Detailed ways

In order to enable those skilled in the art to better understand the solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

With the development of Internet technology, more and more users socialize through the Internet, and social software is the carrier that supports the above social behaviors. Users can socialize online through user accounts registered on social software. Among them, the user can add other users as friends through the account registered on the social software, so as to meet the friend socialization required by the user.

In related technologies, there are many technical solutions for adding friends in social software, but most of them initiate an invitation to add friends based on the premise that the invited party has registered and used the same social software account; however, if the invited party If there is no account registered for the social software, the invitation path will become longer, and the inviting user needs to perform some repeated operations, which is very cumbersome and affects the user experience. For example, when a user wants to invite a friend, he needs to search through the corresponding user's mobile phone number. If the other party has registered an account through the mobile phone number, when inviting, enter the mobile phone number to query the user and initiate an invitation; if the other party If the mobile phone number is not used to register an account, then when inviting, it will prompt "the user does not exist". At this time, the user needs to notify the friends who want to invite to download and install the application, and register an account, and then repeat the invitation process to complete. The process of adding friends will be very cumbersome.

In view of the above problems, the inventor proposed the method, device, server and storage medium for adding friends provided by the embodiment of the present application, which can realize that when a user adds a friend who has not registered an account, both parties can complete the friend adding without too many operations. added to improve the user experience. . Wherein, the specific method of adding a friend will be described in detail in the subsequent embodiments.

The application environment involved in the embodiment of the present application is firstly introduced below.

Please refer to FIG. 1 , the application environment involved in the method for adding friends provided by the embodiment of the present application includes a friend adding system 10 . The friend adding system 10 includes a server 100 and multiple user terminals (only the first user terminal 201 and the second user terminal 202 are shown in FIG. 1 ). The server can communicate with the user terminal to implement the method for adding a friend provided in the embodiment of the present application. For example, the first user terminal 201 uses the installed target application to send a friend addition request carrying communication information to the server 100; after the server 100 receives the friend addition request sent by the first user terminal 201, if The corresponding second user account, based on the communication information, sends invitation information to the second user terminal 202, the invitation information carries a download link, so that the second user can register the target application based on the download link carried in the invitation information. User account: After the user corresponding to the second user terminal 202 registers the second user account on the second user terminal 202, the server 100 can query the second user account, and then send a friend addition request to the second user terminal, to be received When the second user terminal 202 returns the indication information for indicating that the request for adding a friend is approved, a friend relationship between the first user account and the second user account is established in the target application.

Wherein, the first user terminal 201 and the second user terminal 202 may be smartphones, wearable devices, tablet computers, notebook computers, vehicle-machine equipment, etc., which are not limited here; the server 100 may be an independent physical server, or It is a server cluster or distributed system composed of multiple physical servers, and it can also be a cloud server. For example, as shown in Figure 2, the server 100 may include a first server 101, a second server 102, and a third server 103, and the first server 101, the second server 102, and the third server 103 may communicate with each other, and the first server 101 can be used for account management, when receiving a friend adding request, query whether there is an account registered by the added user; the second server 102 can be used to send a friend adding request to the user terminal of the added user; the third server 103 can be used to send invitation information carrying the download link of the target application to the user terminal of the invited user. For example, the third server 103 can serve as a short message platform server and send a short message carrying the download link to the invited user. terminal.

The method for adding a friend provided by the embodiment of the present application will be described in detail below with reference to the accompanying drawings.

Please refer to FIG. 3 . FIG. 3 shows a schematic flowchart of a method for adding a friend provided by an embodiment of the present application. In a specific embodiment, the method for adding friends is applied to the above-mentioned server. The following will take the server as an example to illustrate the specific process of this embodiment. The process shown in Figure 3 will be described in detail below, and the method for adding a friend may specifically include the following steps:

Step S110: Receive a first friend addition request sent by a first user terminal, where the first friend addition request carries communication information.

In this embodiment of the present application, the first user may initiate a first friend addition request for adding the user account of the second user as a friend in the target application through the first user terminal. Correspondingly, the server may receive the first friend addition request sent by the first user terminal. Wherein, the target application can be any application program including social functions, which can provide a friend function, and different users can use the target application in their respective terminals, and perform addition of friends and social interaction required by the user; the communication information is used for The server notifies the second user of the information related to the request for adding the first friend, which may be a mobile phone number, an email address, etc., and the specific communication information may not be limited.

In some embodiments, the target application may be installed in the first user terminal, and when the first user terminal runs the target application, the friend management interface may be displayed according to the user's operation; During the operation, in response to the operation, the input communication information is received, and a friend addition request carrying the communication information is sent to the server. Wherein, when the first user inputs an operation on the friend management interface, he may initiate a friend addition request by inputting the communication information of the second user. For example, the first user terminal may send a request for adding a friend corresponding to the mobile phone number to the server according to the mobile phone number input by the user.

In other embodiments, the first user terminal can access the online web page of the target application, and the first user terminal can access the online page managed by the friend of the target application according to the user's operation; The operation in the online page sends a friend addition request to the server. Certainly, the specific manner in which the first user terminal initiates the request for adding the first friend may not be limited.

Step S120: If there is no second user account corresponding to the communication information, based on the communication information, send invitation information to the second user terminal, where the invitation information is used to instruct the second user terminal to The download link carried in registers the second user account of the target application.

In this embodiment of the application, after receiving the above-mentioned first friend addition request, the server may, in response to the first friend addition request, search for the second user account corresponding to the communication information from the stored user accounts of the target application; if If the second user account corresponding to the communication information is not found, it means that the user corresponding to the communication information has not previously registered the second user account of the target application. In this case, a friend addition request cannot be initiated to the second user account. Therefore, the server The invitation information carrying the download link of the target application may be generated, and based on the communication information carried in the first friend adding request, the invitation information is sent to the second user terminal corresponding to the communication information. Thus, after the second user terminal receives the invitation information, the second user corresponding to the second user terminal can directly register the second user account based on the download link in the invitation information. Optionally, the second user can download and install the target application through the second user terminal. After the target application is installed, the target application can be run through the second user terminal, and a user account of the target application can be registered, so as to complete the subsequent friends added.

In this embodiment of the present application, after receiving the above-mentioned first friend addition request, if the server finds the user account corresponding to the communication information, it may send the first friend addition request to the second user terminal. Specifically, the server may send the first friend addition request to the target application installed on the second user terminal, so that the second user can process the first friend addition request in the target application installed on the second user terminal.

In some implementations, the type of invitation information corresponds to the type of communication information. For example, when the communication information is a mobile phone number, the server may send an invitation text message to the second user terminal, and the invitation text message carries a download link of the target application, and is used to instruct the user to register the target application based on the download link in the invitation text message. The second user account; when the communication information is an email address, the server may send an invitation email to the email client of the second user terminal, and the invitation email carries a download link of the target application. Certainly, the specific type of the invitation information may not be limited.

In some implementations, besides the download link of the target application, the invitation information may also include prompt content, so as to prompt the second user account for registering the target application based on the download link. For example, if the first user corresponding to the first user terminal is A, and the target application is application 1, the prompt content may be "A is inviting you to become a friend in application 1, please download and install application 1 through this download link. , after installing App 1, you can register a user account to pass A's friend request and become friends with A in App 1." Of course, the content of the reminder is just an example, and does not represent a limitation to the specific content of the reminder.

Step S130: When the second user account exists, send the first friend addition request to the second user terminal.

In this embodiment of the application, after the server sends the above invitation information to the second user terminal, if the second user corresponding to the second user terminal completes the target application through the second user terminal based on the invitation information received by the second user terminal, For the registration of the second user account, the server may detect the second user account of the target application registered by the second user terminal, and send the first friend addition request to the second user terminal, so as to complete the friend addition required by the user. Specifically, the server may send the first friend addition request to the target application installed on the second user terminal, so that the second user corresponding to the second user terminal can process the first friend request in the target application installed on the second user terminal. Friend add request.

In some implementations, after the server sends the above invitation information to the second user terminal, if the second user corresponding to the second user terminal registers a user account based on the download link in the invitation information, the server may receive the registration request, and In response to the registration request, a second user account is generated. After the second user account is generated, a first friend adding request may be sent to the second user terminal.

In some implementations, if the server used to manage user accounts is another server, that is, the server that executes the method for adding friends provided in the embodiments of the present application is not the same server as the server used to manage user accounts, then the second user When the user account of the target application is registered, the server cannot know that the second user has registered the user account of the target application. Therefore, the server may query from the server for managing user accounts in real time whether there is a second user account for the target application registered by the second user terminal, or query the server for managing user accounts whether there is a second user account for the target application every interval of target time. The second user account of the target application registered by the second user terminal, so as to be able to know in time that the second user terminal has registered the second user account of the target application, so as to send the first friend adding request to the second user terminal in time.

Step S140: Responding to receiving the target indication information returned by the second user terminal, establishing a friend relationship between the first user account corresponding to the first user terminal and the second user account in the target application , the target indication information is used to instruct the second user terminal to agree to the first friend addition request.

In this embodiment of the application, after receiving the first friend addition request, the second user terminal may display the first friend addition request for the second user corresponding to the second terminal to process the first friend addition request; When the second user terminal detects that the second user has passed the operation of the first friend request, it can send target indication information indicating that the first friend request has passed to the server. After receiving the target indication information, the server can respond to the target. The instruction information determines that the second user has agreed to the friend application, thereby establishing a friend relationship between the first user account corresponding to the first user terminal and the second user account in the target application, and storing the friend relationship.

It should be noted that the first user terminal and the second user terminal in this embodiment and subsequent embodiments do not refer to only one user terminal, and the first user terminal may be all users corresponding to the user account corresponding to the first friend addition request. The user terminal, the second user terminal may be all user terminals corresponding to the above communication information.

In the method for adding a friend provided by the embodiment of the present application, if there is no user account corresponding to the communication information carried in the friend addition request, the server sends the invitation information carrying the download link of the target application to the second user terminal, which is convenient. It saves the second user terminal from downloading the target application, and avoids the cumbersome operations of searching and installing the target application; only when the second user terminal completes the registration of the user account of the target application, the friend addition request is initiated to the second user terminal, ensuring that the server There is no need to send an invalid friend addition request; and when the second user terminal passes the friend addition request, a friend relationship between the first user account and the second user's user account in the target application is established, thereby realizing the first A user adds a friend to a second user who has not registered a user account, and the first user does not need to perform repeated operations, which effectively reduces user operations and improves user experience.

Please refer to FIG. 4 , which shows a schematic flowchart of a method for adding a friend provided by another embodiment of the present application. The method for adding a friend is applied to the above-mentioned server. The process shown in FIG. 4 will be described in detail below. The method for adding a friend may specifically include the following steps:

Step S210: Receive a first friend addition request sent by a first user terminal, where the first friend addition request carries communication information.

Step S220: If there is no second user account corresponding to the communication information, based on the communication information, send invitation information to the second user terminal, where the invitation information is used to instruct the second user terminal to The download link carried in registers the second user account of the target application.

In the embodiment of the present application, reference may be made to the contents of other embodiments for step S210 and step S220, and details are not repeated here.

Step S230: Store the first friend addition request in a queue to be invited.

In this embodiment of the application, after receiving the first friend addition request, the server may also store the first friend addition request in the queue to be invited if it determines that there is no second user account corresponding to the communication information. , so that the server can record the unexecuted friend addition request, and execute the first friend addition request when the second user corresponding to the second user terminal completes registration of the user account of the target application. Understandably, when processing each user's friend addition request, the server may temporarily store the friend addition request in the queue to be invited when the added user has not registered a user account, so that the added user can register When the user account is registered, execute the friend addition request to complete the invitation required by the user.

In some implementations, the friend addition requests stored in the queue to be invited may not be prioritized, and for new friend addition requests that need to be stored in the queue to be invited, the server may store them in an idle position in the queue. Optionally, the server can also record the moment when the server in the queue to be invited receives each friend addition request, so as to determine the time length from the current moment when each friend addition request is received, so that the friend addition request in the invitation queue can be treated according to the time length Do the corresponding processing.

It should be noted that, in this embodiment of the present application, the sequence of the server performing "sending invitation information to the second user terminal based on the communication information" and "storing the first friend addition request in the queue to be invited" may not be performed. It is defined that when it is determined that there is no second user account, an invitation message may be sent to the second user terminal based on the communication information first, and then the first friend addition request is stored in the queue to be invited; The first friend addition request may be stored in the queue to be invited first, and then based on the communication information, send invitation information to the second user terminal; or, "based on the communication information, send the invitation information to the second user terminal" may be executed in parallel. The second user terminal sends invitation information" and "stores the first friend addition request in the queue to be invited".

Step S240: When the second user account exists, send the first friend addition request to the second user terminal, and delete the first friend addition request from the queue to be invited.

In this embodiment of the application, after the server sends the above invitation information to the second user terminal, if the second user terminal completes the registration of the user account in the target application based on the download link, the server can detect the second user account. In this case, the server may execute the first friend addition request in the queue to be invited, and send the first friend addition request to the second user terminal, so as to complete the friend addition required by the user. In addition, since the first friend addition request initiated by the first user terminal has been executed, the server may also delete the first friend addition request from the queue to be invited after successfully sending the first friend addition request, so as to ensure that the first friend addition request The friend addition requests stored in the queue to be invited are unexecuted friend addition requests.

Step S250: In response to receiving target indication information returned by the second user terminal, establish a friend relationship between the first user account and the second user account in the target application, the target indication information It is used to instruct the second user terminal to agree to the first friend addition request.

In the embodiment of the present application, for step S250, reference may be made to the contents of other embodiments, which will not be repeated here.

In the method for adding a friend provided by the embodiment of the present application, if the communication information carried in the friend addition request does not correspond to the second user account, the friend addition request will not be executed temporarily, but the friend addition request will be stored in the to-be-invited In the queue; only when the second user terminal completes the registration of the second user account of the target application based on the download link carried in the invitation information, execute the first friend addition request in the queue to be invited, and send the friend request to the second user terminal The adding request is to establish a friend relationship between the user account in the target application and the user account of the second user under the condition that the second user terminal agrees to the friend adding request, thereby realizing the first user's registration of the unregistered user account. The friend of the second user is added, and the first user does not need to perform repeated operations, which effectively reduces user operations and improves user experience. Moreover, storing unsent friend addition requests in the queue to be invited can avoid missing unexecuted friend invitations.

Please refer to FIG. 5 , which shows a schematic flowchart of a method for adding a friend provided by another embodiment of the present application. The method for adding a friend is applied to the above-mentioned server. The process shown in FIG. 5 will be described in detail below. The method for adding a friend may specifically include the following steps:

Step S310: Receive a first friend addition request sent by a first user terminal, where the first friend addition request carries communication information.

Step S320: If there is no second user account corresponding to the communication information, based on the communication information, send invitation information to the second user terminal, where the invitation information is used to instruct the second user terminal to The download link carried in registers the second user account of the target application.

Step S330: Store the first friend addition request in a queue to be invited.

In this embodiment of the present application, for steps S310 to S330, reference may be made to the contents of other embodiments, and details are not repeated here.

Step S340: If the second friend addition request carrying the communication information sent by the first user terminal is received, determine whether the first friend addition request exists in the queue to be invited.

After the server receives the above-mentioned first friend addition request, if it is determined that there is no second user account, add the first friend addition request to the queue to be invited, and send the invitation information to the second user terminal based on the communication information , if the second user terminal does not register the second user account of the target application according to the invitation information, the server will not perform the step of sending the first friend addition request to the second user terminal, that is, the first friend addition request will continue to exist in It's in the invite queue. In this case, there may be a situation where the first user terminal initiates the same friend addition request again. At this time, the re-initiated friend addition request can be used as the second friend addition request. If the server directly responds to the second friend addition request, then If the invitation information is sent to the second user terminal again, the user may maliciously add friends and the problem of information bombing may occur.

Therefore, in this embodiment of the application, if the second friend addition request carrying the communication information sent by the first user terminal is received, the server can determine whether the above-mentioned first friend addition request exists in the queue to be invited. The above-mentioned first friend addition request means that the server has sent invitation information to the second user terminal before, but the second user terminal has not registered the user account according to the invitation information.

In this embodiment of the application, if there is no first friend addition request in the waiting queue, it means that the second user terminal has completed the registration of the user account according to the invitation information. In this case, it may be that the second user terminal has not passed the first friend request. The request to add a friend may also be that the second user terminal has canceled the account of the target application after passing the first request to add a friend. At this time, the first user terminal needs to add a friend again. Therefore, the server may send invitation information to the second user terminal based on the communication information if there is no second user account according to the processing logic of the first friend addition request, and send invitation information to the second user terminal if there is a second user account. The user terminal sends the second friend addition request, and establishes a friend relationship between the first user account and the second user account when receiving the target indication information returned by the second user terminal. If there is a second user account, the server may directly send a second friend addition request to the second user terminal, so as to complete the friend invitation required by the user.

Step S350: If there is the first friend addition request, ignore the second friend addition request.

In this embodiment of the application, if there is the above-mentioned first friend addition request in the queue to be invited, in order to avoid causing information bombardment to the second user, the server may ignore the second friend addition request received this time.

In some implementations, if there is the above-mentioned first friend addition request in the queue to be invited, the server may obtain the interval between the current time and the target time as the first time, and the target time is the time when the invitation information is sent; if the first If the duration is less than the first threshold, the second friend addition request is ignored. Understandably, if the server sends the invitation information to the second user terminal according to the first friend addition request, but the second user fails to download and install the target application and register the user account according to the invitation information, it may be that the second user missed the request. the invitation message. Therefore, in order to realize that the first user can send the invitation information to the second user terminal through another friend addition request, the server can obtain the interval time from sending the invitation information last time as the first time length, and compare the first time length with the second time length. If the first time length is greater than or equal to the first threshold value, it means that the invitation information has been sent for a long time, so the invitation information can be sent again; if the first time length is less than the first threshold value, it means that the invitation information has been sent before. The interval of the second friend can be ignored in order to avoid text message bombing. Wherein, the specific value of the first threshold may not be limited, for example, it may be 5 hours, 12 hours, 24 hours, 1 week and so on.

In some implementations, if the first friend addition request continues to exist in the queue to be invited, and the second user terminal does not process the invitation information, the first user terminal cannot initiate a friend addition request again to the second user. The terminal sends an invitation message. Therefore, the server can also detect the length of time that the first friend addition request exists in the queue to be invited, and if the time length of the first friend addition request to exist in the queue to be invited reaches the second length of time, it means that it is longer than the time since the last invitation message was sent. Therefore, the first friend addition request can be deleted from the invitation queue, so that the first user terminal can send the invitation information to the second user terminal by initiating a friend addition request again. Wherein, the specific value of the second duration may not be limited, for example, it may be 5 hours, 12 hours, 24 hours, 1 week and so on.

Step S360: When the second user account exists, send the first friend addition request to the second user terminal.

Step S370: In response to receiving the target indication information returned by the second user terminal, establish a friend relationship between the first user account corresponding to the first user terminal and the second user account in the target application , the target indication information is used to instruct the second user terminal to agree to the first friend addition request.

In this embodiment of the present application, reference may be made to the contents of other embodiments for step S360 and step S370, and details are not repeated here.

The method for adding a friend provided by the embodiment of the present application enables a first user to add a friend of a second user who has not registered a user account, and the first user does not need to perform repeated operations, which effectively reduces user operations and improves user experience. Moreover, storing unsent friend addition requests in the queue to be invited can avoid missing unexecuted friend invitations. In addition, when a friend addition request is received again, if the previous friend addition request exists in the queue to be invited, the friend addition request received again is ignored, which can avoid bombardment of user information and ensure user experience.

Please refer to FIG. 6 . FIG. 6 shows a schematic flowchart of a method for adding a friend provided by another embodiment of the present application. The method for adding a friend is applied to the above-mentioned server. The process shown in FIG. 6 will be described in detail below. The method for adding a friend may specifically include the following steps:

Step S410: Receive a first friend addition request sent by a first user terminal, where the first friend addition request carries communication information.

In the embodiment of the present application, for step S410, reference may be made to the contents of other embodiments, which will not be repeated here.

Step S420: Obtain the target request that satisfies the target condition among the friend adding requests sent by the first user terminal in history, and the target condition is used to indicate that there is no target application registered by the other party when the server receives the friend adding request user account.

In this embodiment of the application, after receiving the above-mentioned first friend adding request, before responding to the first friend adding request, the server may first obtain all friend adding messages sent by the first user terminal history and carrying communication information of other users. request, and determine the target request that meets the target condition from all friend adding requests. This target condition is used to represent that there is no user account of the target application registered by the other party when the server receives the friend adding request, that is, when the server receives the target request, there is no user account of the target application registered by the added friend. That is, the server will send invitation information to the user terminal of the other party. Therefore, the above-mentioned target request can be obtained, so that the above-mentioned target request can determine whether the first user corresponding to the first user terminal has a behavior of maliciously triggering sending invitation information to other users.

Step S430: Obtain the response information corresponding to each friend addition request in the target request, the response information is used to indicate whether the other party has downloaded and registered the user account of the target application.

In this embodiment of the application, the server may store the response information of each friend addition request in the friend addition request initiated by the user history, the response information refers to whether the user terminal that is sent the invitation information registers the target application according to the download link Results for user accounts. After determining the target request, the server may determine the response information corresponding to each friend adding request in the target request according to the stored response information.

Step S440: If the response information corresponding to the target request satisfies the preset response condition, and there is no user account of the target application registered by the second user, based on the communication information, send invitation information to the second user terminal The invitation information is used to instruct the second user terminal to register the second user account of the target application based on the download link carried in the invitation information.

In this embodiment of the application, after the server obtains the response information corresponding to each friend adding request in the target request, it can determine whether it satisfies the preset response condition according to the response information corresponding to the target request; if it meets the preset response condition, which means that the first user corresponding to the first user terminal does not have any behavior of maliciously triggering the sending of invitation information to other users; Steps to add friends required by the user; if the preset response conditions are not met, it means that the first user maliciously triggers sending invitation information to other users.

In some embodiments, the preset response condition may include: the quantity of the first response information in the response information corresponding to the above-mentioned target request is greater than the preset quantity, and the first response information indicates that the other party registers the target application based on the download link user account. It can be understood that if the number of the first response information is greater than the preset number, it means that when the first terminal initiates a request to add a friend before, the added user often registers a user account through the user terminal, so it can be determined that the first The user does not maliciously trigger the behavior of sending invitation information to other users; if the number of the first response information is not greater than (less than or equal to) the preset number, it means that when the first user terminal initiated a friend addition request before, the added user It is rare to register a user account through a user terminal, so it can be determined that the first user maliciously triggers sending invitation information to other users. Wherein, the specific value of the preset number may not be limited, it may be a preset fixed value, or may be determined according to the total number of the above-mentioned friend addition requests initiated by the first user terminal history, for example, the total number may be compared with the target ratio The product, as a preset quantity, can be 50%, 60%, 80% and so on, which is not limited here.

In some implementations, the preset response condition may include: the proportion of the first response information in the response information corresponding to the target request is greater than a preset ratio, and the first response information is a user account representing that the other party has downloaded and registered the target application . It can be understood that if the proportion of the first response information is greater than the preset proportion, it means that when the first user terminal initiates a friend addition request before, there are many cases of the added user registering a user account through the user terminal, so it can be determined that this The first user does not maliciously trigger the behavior of sending invitation information to other users; if the proportion of the first response information is not greater than (less than or equal to) the preset proportion, it means that when the first user terminal initiated a friend addition request before, It is rare for the added user to register a user account through the user terminal, so it can be determined that the first user maliciously triggers sending invitation information to other users. Wherein, the specific value of the preset ratio may not be limited, for example, it may be 50%, 60%, 80%, etc., which is not limited here.

Step S450: When the second user account exists, send the first friend addition request to the second user terminal.

Step S460: In response to receiving the target indication information returned by the second user terminal, establish a friend relationship between the first user account and the second user account in the target application, the target indication information It is used to instruct the second user terminal to agree to the first friend addition request.

In this embodiment of the present application, reference may be made to the contents of other embodiments for step S450 and step S460, and details are not repeated here.

In the method for adding a friend provided by the embodiment of the present application, if there is no user account corresponding to the communication information carried in the friend addition request, the server determines the Whether the user corresponding to the first user terminal maliciously triggers the behavior of sending invitation information to other users, and only executes the sending of the invitation information and subsequent steps when it is determined that there is no malicious behavior of triggering the sending of invitation information to other users, effectively This prevents the user from maliciously triggering the behavior of sending invitation information to other users.

Please refer to FIG. 7 . FIG. 7 shows a schematic flowchart of a method for adding a friend provided by yet another embodiment of the present application. The method for adding a friend is applied to the above-mentioned server. The process shown in FIG. 7 will be described in detail below. The method for adding a friend may specifically include the following steps:

Step S510: Receive a first friend addition request sent by a first user terminal, where the first friend addition request carries communication information.

Step S520: If there is no second user account corresponding to the communication information, based on the communication information, send invitation information to the second user terminal, where the invitation information is used to instruct the second user terminal to The download link carried in registers the second user account of the target application.

In this embodiment of the present application, reference may be made to the contents of other embodiments for step S510 and step S520, and details are not repeated here.

Step S530: Receive a friend query request sent by the first user terminal for searching the second user account corresponding to the communication information.

Step S540: In response to the friend query request, if there is no friend relationship between the first user account and the second user account, send the invitation information to the second user terminal again.

In this embodiment of the application, after the server sends the above invitation information to the second user terminal, since the first user corresponding to the first user terminal cannot know whether the second user corresponding to the second user terminal has completed the account registration according to the invitation information, The first user addition request is received and the processing of the first user addition request is completed, so the first user may search for friends of the second user account corresponding to the above communication information through the first user terminal. Correspondingly, the server may receive a friend query request sent by the first user terminal; after receiving the friend query request, the server responds to the friend query request to determine whether there is currently a friend relationship between the first user account and the second user account ; If there is no friendship relationship between the first user account and the second user account, the first query result is fed back to the first user terminal, and the invitation information can be sent to the second user terminal again, so as to complete the user's required Adding friends; if there is a friend relationship between the first user account and the second user account, feeding back the second query result to the first user terminal. Wherein, the first query result indicates that there is no friendship relationship between the first user account and the second user account; the second query result indicates that there is a friendship relationship between the first user account and the second user account.

In some implementations, in order to prevent users from querying through friends, other users are bombarded with information. After the server receives the above-mentioned friend query request, if it determines that there is no friend relationship between the first user account and the second user account, it can obtain the interval time between the current time and the target time as the third time. The time when the information is invited; if the third duration is greater than the second threshold, the invitation information is sent to the second user terminal again. Wherein, the specific value of the second threshold may not be limited, for example, it may be 5 hours, 12 hours, 24 hours, 1 week and so on.

Step S550: When the second user account exists, send the first friend addition request to the second user terminal.

Step S560: In response to receiving the target indication information returned by the second user terminal, establish a friend relationship between the first user account and the second user account in the target application, the target indication information It is used to instruct the second user terminal to agree to the first friend addition request.

In this embodiment of the present application, reference may be made to the contents of other embodiments for step S550 and step S560, and details are not repeated here.

In some implementations, since the user corresponding to the first user terminal cannot know whether the first friend addition request has been sent to the second user terminal, it may occur that the first user searches for the added friend. In combination with the above-mentioned embodiment where the friend addition request is stored in the queue to be invited, after the server sends the first friend addition request in the queue to be invited to the second user terminal, the first friend addition request may not be deleted temporarily. If the friend query request sent by the first user terminal is received, the server may check whether there is a friend relationship between the first user account and the second user account; if there is no friend relationship between the first user account and the second user account , then it can be judged whether there is a first friend addition request in the queue to be invited; The user corresponding to the second user terminal initiates a friend addition request.

Optionally, the above-mentioned establishment of a friend relationship may also be establishment of a relationship in which the first user account and the second user account are in the same user group. Exemplarily, in the application scenario where the first user invites the second user to join the family group in the target application through the first user terminal, the above friend query request initiated by the first user through the first user terminal may be to query the second user Whether the second user account is already in the group, the specific processing flow diagram may be as shown in FIG. 8 . Wherein, the first user can query whether the second user account of the second user is already in the group by logging into the target application; if the second user account of the second user is already in the group, the first user account of the first user The terminal enters the function page with the group information; if the second user account of the second user is not in the group, it can be judged whether there is a first friend addition request in the queue to be invited; if there is the first friend addition request, then Send the first friend addition request to the second user terminal; correspondingly, the second user terminal may receive the first friend addition request; if the second user terminal accepts the first friend addition request, the server may establish the second user The corresponding relationship between the account number and the group, so that after the first user terminal inquires whether the second user account of the second user is already in the group, it can enter the function page with the group information; A friend addition request, or after sending the first friend addition request to the second user terminal, the second user terminal does not accept the first friend addition request, then returns instruction information to the first user terminal, so that the first user terminal stays in the query page.

The method for adding a friend provided by the embodiment of the present application enables a first user to add a friend of a second user who has not registered a user account, and the first user does not need to perform repeated operations, which effectively reduces user operations and improves user experience. Moreover, storing unsent friend addition requests in the queue to be invited can avoid missing unexecuted friend invitations. In addition, after sending the invitation information to the second user terminal, if a friend query request for the second user account is received from the first user terminal, if there is no friend between the first user account and the second user account relationship, send the invitation message to the second user terminal again, so as to better prompt the second user to process the invitation message, and complete the friend addition required by the user.
