Fig. 2 is a schematic architecture diagram of an application system in a display device provided in the present application. As shown in fig. 2, in some embodiments, the system is divided into four layers, from top to bottom, an application layer (abbreviated as "application layer"), an application framework layer (Application Framework) layer (abbreviated as "framework layer"), a An Zhuoyun line (Android run) and a system library layer (abbreviated as "system runtime layer"), and a kernel layer, respectively.

The framework layer provides an application programming interface (application programming interface, API) and programming framework for application programs of the application layer. The application framework layer includes a number of predefined functions. The application framework layer corresponds to a processing center that decides to let the applications in the application layer act. Through the API interface, the application program can access the resources in the system and acquire the services of the system in the execution.

In some embodiments, the kernel layer may also include a power management module for power management. In some embodiments, the software programs and/or modules corresponding to the software architecture in fig. 2 may be stored in the first memory shown in fig. 1, for example.

In general, when using an application installed in the display device, a user first needs to log in, so that the display device can execute a corresponding function through the logged-in application.

At present, taking a user login application program a as an example, the existing application program login method mainly includes the following steps:

1. the display device receives a user name and a password input by a user for logging in the application program a, and the display device can realize logging in the application program a by using the user name and the password.

2. The user's terminal device (e.g., a mobile phone) also needs to install the application a. The user opens an application a installed on the terminal device. And the terminal equipment responds to the operation of clicking the code scanning control in the interface of the application program A on the terminal equipment by a user, and scans the login two-dimensional code displayed by the display equipment by using the code scanning function provided by the application program A. That is, the method requires login of the application a on the display device based on the terminal device of the user.

3. The display equipment receives a login verification code received by a user terminal and input by a user, and the application program A is logged in through the verification code.

4. A near field communication (Near Field Communication, NFC) module is set in the display device, and a user uses an NFC card storing user name and password information to get close to the NFC module, so that the display device can obtain the user name and password, and further login application a is achieved.

However, when the application program is logged in by using the above method, a user needs to perform a manual operation to log in the application program. That is, each time a user opens a new application, the above-mentioned manual login operation needs to be performed once, and the display device can execute the function corresponding to the newly opened application. Therefore, the existing application program login method has the problem of low efficiency.

Considering that the existing application program login method has low efficiency, the problem is that each time a user opens a new application program, a manual login operation is needed to be performed, so the application program login method can be realized without the need of the user to perform the login operation. By the method, when a user opens an application program, the display device can automatically log in the application program, so that the login efficiency of the application program is improved, and the user experience is improved.

Fig. 3 is a schematic application scenario diagram of an application program login method provided in the present application. As shown in fig. 3, the display device may automatically obtain login information used by the user to login to the first target application from the server in response to the user-triggered operation of opening the first target application, and use the information to perform automatic login of the first target application.

The technical scheme of the present application will be described in detail with reference to specific embodiments. The following embodiments may be combined with each other, and some embodiments may not be repeated for the same or similar concepts or processes.

Fig. 4 is a flow chart of an application program login method provided in the present application. As shown in fig. 4, the method may include the steps of:

s101, the display device responds to the operation of opening the first target application program triggered by the user to determine whether a second target application program which is logged in by the user exists.

Alternatively, the display device may control the display screen to display icons of a plurality of application programs, for example. The user may trigger an operation of opening the first target application by clicking an icon of the first target application.

Optionally, when the display device logs in the second target application program, for example, the login information for logging in the second target application program may be obtained through any one of the existing application program login methods, so as to log in the second target application program by using the login information for logging in the second target application program. In addition, the display device may also store an identification of the second target application. In this implementation, optionally, the display device may determine whether the second target application program that the user has logged in exists by determining whether an identifier of the logged-in application program is stored in itself. If the display device determines that the identifier of the logged-in application program is stored in the display device, it may determine that a second target application program logged-in by the user exists. If the display device determines that the identifier of the logged-in application program is not stored, it may determine that a second target application program that the user has logged in exists.

If there is a second target application that is already logged in, indicating that the display device may log in the first target application based on the second target application, the display device may perform step 102 to send a first login information request to the server.

If there is no second target application program already logged in, optionally, the display device may execute step S106, for example, to control the display screen to display a login interface corresponding to the first target application program.

It should be understood that the types of the first target application and the second target application are not limited in this application. The first target application or the second target application may be, for example, a teaching application or a video application. The first target application and the second target application may be the same type of application or different types of application. In addition, it should be understood that, when the display device responds to the user triggering the operation of opening the first target application program, it is not limited whether the logged-in second target application program still maintains the login state.

S102, the display device sends a first login information request to the server.

Wherein, the first login information request includes: the user logs in the second login information used by the second target application program and the identification of the first target application program to be logged in.

Alternatively, the second login information may be a user name used by the user to log in to the second target application. Alternatively, the second login information may be a user name and a password used by the user to login to the second target application.

The identifier of the first target application to be logged in may be, for example, a name of the first target application, or a unique representation code or the like may be capable of uniquely representing the identifier of the first target application.

Accordingly, the server may receive a first login information request from the display device.

S103, the server acquires first login information used by the user to login the first target application program according to the second login information and the identification of the first target application program.

Alternatively, the first login information may be a user name used by the user to login to the first target application program. Alternatively, the first login information may be a user name and a password used by the user to login to the first target application.

Wherein the server stores login information of at least one application program of the user. The server may acquire first login information for logging in the first target application from the login information of the at least one application.

As a possible implementation, the server may have stored therein login information of at least one application associated with the second login information, for example. The server may acquire first login information for logging in the first target application from the login information of the at least one application associated with the second login information according to the identification of the first target application.

S104, the server sends first login information to the display device.

Accordingly, the display device may receive the first login information used by the user from the server to login to the first target application.

It should be understood that the communication manner between the display device and the server, and the communication protocol used are not limited in this application.

S105, the display device uses the first login information to login the first target application program, and displays a page after the first target application program is logged in.

Optionally, after the first login information is obtained, the display device may use the first login information to connect with a server corresponding to the first target application program, so as to implement the first target application program, and display a page after the first target application program is logged in. It should be understood that the communication manner between the display device and the server corresponding to the first target application program, and the communication protocol used are not limited.

S106, the display device controls the display screen to display a login interface corresponding to the first target application program.

Alternatively, when there is no second target application program that has been logged in, the display device may execute this step S106, and then, the display device may receive the first login information input by the user through the login interface corresponding to the first target application program. Then, the display device may perform the aforementioned step S105, that is, log in the first target application according to the first login information.

It should be understood that, the specific implementation manner of receiving the first login information input by the user through the login interface corresponding to the first target application by the display device is not limited in this application. Alternatively, reference may be made to any of the aforementioned existing application login methods, which are not described herein.

Further, in this implementation manner, as a possible implementation manner, after receiving the first login information input by the user, the display device may further send the first login information to the server, so that the server may store the first login information. By the method, the login information of the application program stored in the server can be updated, and the accuracy of automatically logging in the first target application program by the application program login method is improved.

Further, after receiving the first login information input by the user, the display device may further store the first login information and the identifier of the first target application program, so that when other application programs are opened subsequently, the display device may automatically log in the other application programs based on the first login information and the identifier of the first target application program.

In this embodiment, when there is a second target application program that the user has logged in, the display device may send, to the server, a first login information request including second login information used by the user to login the second target application program, and an identification of the first target application program to be logged in. By the method, the display device can request to acquire the first login information used by the user to login to the first target application program from the server. After receiving the first login information request, the server may acquire the first login information based on the second login information and the identifier of the first target application program, and send the first login information to the display device. Through the first login information, the display device can login the first target application program and display a page after the first target application program is logged in, so that the first application program can be automatically logged in. By the method, when a user opens the first application program, the user does not need to manually input the first login information, the display device can realize automatic login of the first application program, the login efficiency of the application program is improved, and the user experience is improved.

As a possible implementation manner, if the first target application program runs in the display device for the first time, the display device registers the first target application program in the server so that the server can feed back the first login information corresponding to the first target application program. After the first login information is registered in the server, the server can feed back the first login information corresponding to the first target application program, so that the safety of automatically logging in the first target application program through the application program login method is improved.

Optionally, if the first target application is running in the display device for the first time, the display device may first obtain the identifier of the first target application, and then register the first target application in the server according to the identifier of the first target application, so that the server checks the first target application according to the identifier of the first target application. Wherein, optionally, the display device registering the first target application program in the server according to the identifier of the first target application program may refer to that the display device sends a registration request including the identifier of the first target application program to the server, for example. The server may then store the identification of the first target application in a registration list to enable registration of the first target application in the server.

In this implementation manner, as a possible implementation manner, before the server obtains the first login information according to the second login information and the identifier of the first target application program, the server may further verify the first target application program according to the identifier of the first target application program, to obtain a verification result used for characterizing whether the first target application program is registered in the server.

Alternatively, the server may check the first target application program, for example, by determining whether there is an identifier of the first target application program in the registration list stored in the server itself. If the server queries the identity of the first target application program in the registration list stored by the server, the server can determine that the verification result is used for representing that the first target application program is registered in the server. If the server does not query the registration list stored by the server for the identification of the first target application program, the server may determine that the verification result is used to characterize that the first target application program is not registered in the server.

If the verification result is used to indicate that the first target application program is registered in the server, and indicates that the server can perform the service of automatically logging in the first target application program, the server can execute the step S103, that is, can obtain the first login information according to the second login information and the identifier of the first target application program.

If the verification result is used for representing that the first target application program is not registered in the server, the server can not automatically log in the service of the first target application program, and optionally, the server can send first prompt information to the display device. The first prompt information may be used to characterize a failure of the server to acquire the first login information.

Or as another possible implementation manner, after the verification result is used for representing that the first target application program is registered in the server and the first login information is stored, the server further judges whether the duration of the server for storing the first login information exceeds the preset duration, so that the accuracy of acquiring the first login information is further improved, and the accuracy of automatically logging in the first target application program by the display device based on the first login information is further improved.

If the verification result is used for indicating that the first target application program is registered in the server, and the duration of storing the first login information by the server exceeds the preset duration, which indicates that the first login information may not be the login information corresponding to the user triggering the operation of opening the first target application program, the server may also send the first prompt information to the display device. The preset duration may be, for example, stored in the server in advance for the user.

If the verification result is used for indicating that the first target application program is registered in the server, and the duration of storing the first login information by the server does not exceed the preset duration, and the first login information is the login information corresponding to the user triggering the operation of opening the first target application program, the server can send the first login information to the display device.

In this implementation manner, if the display device receives the first prompt information, it is stated that the server fails to acquire the first login information, or the first login information may not be the login information corresponding to the user triggering the operation of opening the first target application program, the display device may execute the step S106 to control the display screen to display the login interface corresponding to the first target application program, and then receive, through the login interface corresponding to the first target application program, the first login information for logging in the first target application program, which is input by the user. According to the first login information, the display device may login to the first target application.

In this embodiment, by registering the first application program in the server, the server may feed back the first login information to the display device only when the first target application program is registered in the server based on the application program that is determined to be capable of feeding back the login information, so that computing resources of the server are saved, and security of the display device automatically logging in the first target application program based on the first login information fed back by the server is improved.

As a possible implementation manner, for the target display device that cannot communicate with the server to obtain login information, the target display device may obtain the login information through, for example, the display device that can communicate with the server to improve the efficiency of the target display device to log in an application program.

Optionally, the target display device may send a synchronous login instruction including an identifier of the third target application program to the display device in response to the operation of opening the third target application program triggered by the user. Accordingly, the display device may receive a synchronous login instruction from the target display device.

The display device may then send a second login information request to the server when there is a second target application that has been logged in. Wherein the second login information request includes: the user logs in second login information used by the second target application program and an identification of a third target application program to be logged in. Alternatively, the server may receive the second login information request and feed back the third login information used by the user to login to the third target application. Optionally, the specific implementation manner of the server feeding back the third login information after receiving the second login information request may refer to the foregoing embodiment, which is not described herein again.

The display device may receive the above-described third login information from the server. Then, the display device may send the third login information to the target display device, so that the target display device may log in the third target application program using the third login information, and display a page after the third target application program is logged in.

Alternatively, the display device may receive a synchronous login instruction from the target display device, for example, based on the WebSocket communication protocol, and send third login information to the target display device. It should be understood that the method for communicating between the display device and the target display device through the WebSocket communication protocol is only one possible implementation provided in the present application, and the communication manner between the display device and the target display device is not limited in the present application.

In this embodiment, the target display device that cannot communicate with the server may obtain the login information through the display device that can communicate with the server, so as to implement automatic login of the application program, and improve efficiency of the target display device to log in the application program.

The following details how the server obtains the first login information used by the user to login to the first target application according to the second login information and the identifier of the first target application:

As a possible implementation manner, the server may determine the user identifier of the user according to the second login information and the mapping relationship between the login information and the user identifier. The user identifier here may be, for example, a mobile phone number of the user, or an identifier such as a user identification card number.

For example, the mapping relationship between the login information and the user identifier may be as shown in the following table 1:

TABLE 1

Login information	User identification
		Login information 1	User identification 1
Login information 2	User identification 2
		Login information 3	User identification 3

Taking the second login information as login information 3 as an example, based on the mapping relationship shown in table 1, the server may determine the user identifier corresponding to the user as identifier 3.

Then, the server may obtain a target mapping relationship corresponding to the user identifier of the user, where the target mapping relationship is a mapping relationship between the identifier of the application program and the login information. Then, the server may obtain the first login information according to the identifier of the first target application program and the target mapping relationship.

For example, the mapping relationship between the identifier of the application program and the login information may be as shown in the following table 2:

TABLE 2

Identification of application programs	Login information
		Identification of application 1	Login information 1
Identification of application 2	Login information 2
		Identification of application 3	Login information 3

Taking the identifier 1 of the first target application as an example, the server may determine that the first login information is login information 1 based on the target mapping relationship shown in table 2.

Taking the foregoing display device as an example of an intelligent blackboard (or referred to as an electronic whiteboard) applied to the teaching field, fig. 5 is a schematic flow chart of another application program login method provided in the present application based on the application scenario shown in fig. 3. As shown in fig. 5, the method may include the steps of:

and step 1, the intelligent blackboard 1 at the main speaker end responds to the operation of opening the first target application program triggered by the user to determine whether a second target application program which is logged in by the user exists.

The first target application program and the second target application program can be created based on a Websocket communication protocol. A server created based on Websocket communication protocol may be installed in the display device so that the display device may perform step 1 and the following steps. The server may be constructed based on (VS), for example.

The display device may acquire an identification of the first target application, an identification of the second target application, data transmission with the server, and the like, based on an application program interface (Application Programming Interface, API) provided by the Websocket communication protocol.

If so, step 2 is performed. If not, step 9 is performed.

And 2, the intelligent blackboard 1 sends a first login information request to the server.

And step 3, the server checks the first target application program according to the identification of the first target application program, and a check result used for representing whether the first target application program is registered in the server is obtained.

If the verification result is used to characterize that the first target application program is registered in the server, step 4 is executed.

If the verification result is used to characterize that the first target application program is not registered in the server, step 8 is executed.

Alternatively, when the first target application is first run in the display device, the display device may implement registration of the first target application in the server by, for example, invoking a first registration synchronization information interface of the server.

And 4, the server acquires first login information used by the user to login the first target application program according to the second login information and the identification of the first target application program.

And 5, the server judges whether the duration of storing the first login information by the server exceeds a preset duration.

If not, executing step 6. If yes, go to step 8.

And 6, the server sends first login information to the intelligent blackboard 1.

Accordingly, the smart blackboard 1 can receive the first login information. Alternatively, the intelligent blackboard 1 may receive the first login information, for example, by acquiring a synchronous login information interface.

And 7, the intelligent blackboard 1 logs in the first target application program by using the first login information, and displays the page after the first target application program is logged in.

And step 8, the server sends first prompt information for representing failure of the server to acquire the first login information to the intelligent blackboard 1.

Accordingly, the intelligent blackboard 1 can receive the first prompt information and execute step 9.

And 9, controlling a display screen to display a login interface corresponding to the first target application program by the intelligent blackboard 1, and receiving the first login information input by a user through the login interface corresponding to the first target application program.

Then, the smart blackboard 1 may perform the aforementioned step 7 to log in the first target application using the first login information, and display the page after the first target application is logged in.

In addition, the display device may also send the first login information to the server by calling a synchronous login user interface of the server, so that the server stores the first login information.

The intelligent blackboard 1 as the main speaker may also receive a synchronous login instruction of the intelligent blackboard 2 as the listening speaker so that the intelligent blackboard 2 can automatically log in an application. The intelligent blackboard 1 and the intelligent blackboard 2 can be a main speaking end and a listening speaking end in a special delivery classroom for remote teaching. When the lectures are given in the special class, the main lecturer logs in the application program, and the lecturer can synchronously and automatically log in a plurality of software, so that the lecture efficiency and the lecture experience of the special class are improved.

Alternatively, the specific implementation procedure may be as follows:

step 10, the intelligent blackboard 2 responds to the operation of opening the third target application program triggered by the user, and sends a synchronous login instruction comprising the identification of the third target application program to the intelligent blackboard 1.

The communication between the smart blackboard 2 and the smart blackboard 1 may be, for example, communication based on Websocket communication protocol. The Websocket communication protocol has the following characteristics:

1. the display device is easy to realize based on the TCP protocol.

2. Has good compatibility with the HTTP protocol. The default ports of Websocket communication protocol are also 80 and 443, and the handshake phase adopts HTTP protocol, so that the handshake is not easy to mask and can pass through various HTTP proxy servers.

3. The Websocket communication protocol belongs to long connection and the HTTP protocol is stateless.

4. The Websocket communication protocol is a two-way communication.

5. The Websocket communication protocol can cross domains and is not limited by the browser homology strategy. The HTTP protocol is not cross-domain.

6. The Websocket communication protocol has the advantages of light data format, low performance cost and high communication efficiency.

7. The Websocket communication protocol may send text or binary data.

8. The protocol identifier of the Websocket communication protocol is ws. If encrypted, wss.

Step 11, the intelligent blackboard 1 obtains third login information used by the user to login to the third target application program from the server based on the identification of the third target application program.

The specific implementation process may refer to the foregoing embodiment, and will not be described herein.

Step 12, the intelligent blackboard 1 transmits the third login information to the intelligent blackboard 2.

And 13, the intelligent blackboard 2 logs in a third target application program by using the third login information, and displays a page after the third target application program is logged in.
