Of course, the above terms are merely explanatory descriptions, and are not to be considered as limiting the present invention.

The following describes the chat record processing method of the instant chat tool according to the exemplary embodiment of the present invention with reference to FIG. 2 to FIG. 6.

2 is a flowchart of a method for processing a chat record of an instant chat tool according to an embodiment of the present invention. As shown in FIG. 2, it may include: S201. In response to a request for obtaining a historical chat record between a current user and a specific user, read a historical chat record between the current user and a specific user from a cache.

In some implementations, the request for obtaining a historical chat record between the current user and a specific user may specifically be a request for triggering the display of the historical chat record between the current user and a specific user. For example, when a user clicks on a control or button such as "Show more messages" or "Get historical chat history", a request is triggered to display the historical chat history between the current user and a specific user. As another example, when the user scrolls down the screen with the mouse in the chat window between the current user and the specific user, a request to trigger the display of the historical chat history between the current user and the specific user can also be sent. It should be noted that the user may send a request to trigger the display of the historical chat record between the current user and the specific user through various operations. The specific implementation manner may be flexible and diverse, and is not limited herein.

In some implementations, the request for obtaining a historical chat record between the current user and the specific user may also be a request for triggering the display of unread instant messages between the current user and the specific user. For example, when a user opens a chat window with a specific user in a chat tool and triggers the display of an unread instant message, it can be determined that a request for obtaining a historical chat record between the current user and the specific user is sent. As another example, if the user closes the chat window with a specific user, when receiving an instant message sent by the specific user to the current user, the instant chat tool can display prompt information to remind the user that there are unread messages . When the user clicks the prompt message to trigger the display of the unread message, it can be determined that a request for obtaining a historical chat record between the current user and a specific user is sent. It should be noted that, in some implementations, after receiving a request to trigger the display of unread instant messages between the current user and a specific user, it may also be determined whether the number or capacity of the unread instant messages is less than a set threshold; If the determination result is yes, it is determined to send a request for obtaining a historical chat record between the current user and a specific user. The setting threshold may be set according to requirements. For example, the setting threshold may be an upper limit of the number or capacity of messages displayed on a display interface of the instant chat tool. The capacity of a message may refer to the number of words, lines, or space occupied by the information contained in the message. For example, suppose the current user A closes the chat window with user B. When receiving a new message from user B to user A, you can determine whether the number or capacity of the new message is greater than the upper limit of the message displayed on the display interface. ; If the judgment result is no, obtain historical chat records, so that new messages and historical chat records can be combined and displayed, so that users can quickly obtain contextual information and facilitate user communication.

In some implementations, the request for obtaining historical chat records between the current user and a specific user may also be receiving an instant message sent by the specific user to the current user and determining that the quantity or capacity of the instant message is less When the threshold is set, a request is sent to obtain the historical chat history between the current user and a specific user. For example, it is different from acquiring historical chat records in response to a user triggering a request to display an unread message. In this embodiment, when a new unread message is obtained and it is determined that the message meets a preset condition, it is triggered. Request to get historical chat history.

In some embodiments, the reading the historical chat records between the current user and the specific user from the cache includes: determining whether the historical chat records between the current user and the specific user have been read from the local storage space; If the determination result is yes, the historical chat history between the current user and the specific user is read from the cache. Further, the method further includes: if the determination result is no, reading the historical chat record between the current user and the specific user from a local storage space, storing the read chat record in a cache, and recording the record from The local storage space has read the historical chat records between the current user and the specific user. For example, when receiving a request for obtaining historical chat records, it can be determined whether the chat records have been read from the local storage space. For example, an identifier can be set to distinguish whether the chat history has been read locally. If it is judged that the chat record has been read from the local storage space according to the set identifier, the chat record is directly read from the cache. If it is determined according to the set identifier that the chat history has not been read from the local storage space, the chat history may be read from the local storage space and stored in the cache. Further, the setting identifier is used to indicate that the chat record has been read from the local storage space. When the request for obtaining the chat history is received again, the chat history can be obtained directly from the cache. Since the local storage space is accessed only when the identity is not read from the local storage space, the chat history is read from the cache in other scenarios, which greatly improves the speed of obtaining chat records and reduces the loss of local storage space. .

In some embodiments, the method further includes: when it is determined that the trigger condition is satisfied, previously reading a historical chat record between the current user and a specific user from a local storage space, and saving the read chat record in a cache in. In this implementation, historical chat records can be read from the local storage space in advance and saved in the cache. When receiving a request to obtain a chat history, the chat history is obtained from the cache every time. The timing for pre-acquiring the historical chat record may be a trigger condition, and the specific trigger condition may be very flexible, as long as the historical chat record is obtained from the local storage space at one time before receiving the request for acquiring the chat record. For example, when receiving an instant message sent by a specific user to the current user, it can be determined that the trigger condition is satisfied. By way of example, when a user triggers an operation to display a chat window between the current user and a specific user, it is determined that the trigger condition is satisfied. Of course, the above is only an exemplary description, and the specific triggering conditions may be flexible and diverse, as long as the historical chat records are obtained from the local storage space at one time before receiving the request for obtaining the chat records.

In some implementations, reading the historical chat records between the current user and the specific user from the cache includes: determining whether the number or capacity of historical chat records between the current user and the specific user stored in the cache is Is greater than the set threshold; if the result of the judgment is yes, historical chat records with a quantity or capacity equal to the set threshold are directly read from the cache; if no, the historical chat records are read from the local storage space and stored in the cache Picking, so that the number or capacity of historical chat records in the cache is greater than or equal to a set threshold. For example, when the user clicks "View more", it can trigger loading of N historical messages. The setting of N can be performed as required. At this time, find the top message of the chat session (the message that is generally the longest from the current time), and then use this message as the boundary to read N historical message records forward from the cache. Specifically, if the history message record in the cache is sufficient, that is, greater than or equal to N, the read historical chat record is directly displayed on the top of the chat session. If it is judged that the history message record saved in the cache is less than N, it is assumed that the eligible cache message is M, and from the local history record, the first message record in the cache is used as the boundary and read forward (NM ), And stored in the cache. Then, find the top message of the chat session, and then use this message as the boundary to read N message records forward from the cache and display them.

In some embodiments, the method further includes: when determining that the historical chat record contains a picture, determining whether a picture corresponding to the picture identifier is stored in the cache according to the picture identifier; if the determination result is yes, starting from the fast Take the picture to get the picture corresponding to the picture ID. Further, if the determination result is no, the picture is obtained from the local storage space, and the picture and the correspondence between the picture and the picture identifier are stored in the cache. For example, when the present invention is specifically implemented, when the chat record is saved, if the chat record contains a picture, only the picture identifier is saved in the chat record for identifying the picture. Further, the present invention may set a picture cache for storing picture data corresponding to the picture ID. When obtaining the historical chat record, if it is determined that the chat record contains a picture, for example, when the chat record contains a picture ID, it can be determined whether the picture corresponding to the picture ID is stored in the picture cache according to the picture ID; if the determination result is yes, The content of the picture is directly obtained for display, thereby greatly improving the speed of obtaining the picture without having to download the picture from the local storage space each time. If it does not exist, read the picture from local storage and save it in the picture cache. Because the pictures in the chat history of the instant chat tool are often duplicated, such as various emoticon pictures, you only need to save the picture in the picture cache and the corresponding relationship between the picture ID and the picture, that is, when you obtain the same picture, you can quickly The picture is directly read in the selection, and the picture with the same picture ID is saved only once in the cache, which reduces the waste of storage space. The picture ID can be obtained by obtaining the MD5 value of the picture. It should be noted that, through the above processing, the speed of obtaining and displaying picture information can be increased independently, without having to read pictures from the local disk each time.

S202: Display historical chat records between the current user and a specific user.

It should be noted that, during specific implementation, the historical chat records can be displayed separately. It can also be combined with unread instant messages. For example, in response to a user triggering a request to display the instant message, the instant message and the historical chat record are combined and displayed.

In some embodiments, the method further includes: saving an access time for obtaining historical chat records from the cache; when a trigger condition is satisfied, determining the least recently used historical chat records according to the access time, and deleting from the cache The history chat. For example, if the current user has a lot of chat records, it will cause more chat records and pictures stored in the cache, occupying computer memory. In order to reduce the memory occupation, you can identify the The access time for the current user to obtain the chat history of a specific user; and it can trigger to determine whether the current cache data exceeds the cache limit and there are no unread new messages in the cache. If so, the latest time is determined based on the access time Least used chat history, delete it from cache. The least recently used chat record may be a record whose access time exceeds a set threshold from the current time, or may be a chat record with the least number of accesses within a preset time. Through the above processing, memory occupation and memory overhead can be effectively reduced.

In some implementation manners, the reading the historical chat records between the current user and the specific user from the cache includes: reading from the cache a part of the historical chat records between the current user and the specific user that meets specific conditions; The specific condition includes a historical chat record that meets a specific time condition, a specific location condition, or a specific keyword; the display of the historical chat record between the current user and the specific user includes: a display of the part of the historical chat record, wherein the part Each chat record in the historical chat record does not have a time-continuous relationship or the historical chat record does not have a time-continuous relationship with the recently displayed chat record of the current instant chat tool. In specific implementation, instead of obtaining all chat records between the current user and a specific user and continuously displaying the chat records in chronological order, only part of the historical chat records that meet specific conditions can be obtained and displayed. Examples are historical chats that meet certain time conditions. Assume that the current time is Friday, and the current user A and the specific user B are chatting through the instant chat tool. User B mentioned: "How are we doing on Tuesday?" At this time, User A is likely to want to see Tuesday ’s chat history. At this time, "Tuesday" can be identified as a keyword. Only get the historical chat history corresponding to Tuesday from the cache, and display the chat history of Tuesday in the chat interface. In this way, the chat history on Tuesday and the most recent chat history (Friday) displayed in the current window do not have a time continuous relationship. In this way, not only can you get less information, but also it is convenient for users to intuitively view the content of interest without having to have a large number of chat records (such as all chat records in the continuous time period from Friday to Tuesday) Find what you ’re interested in. As another example, the chat record may also be a chat record that meets the conditions of a specific place. Assuming that the current user frequently travels on a business trip, the login location may be changed, and the chat history of a specific place may be obtained according to the user's input. By way of example, this part of the historical chat record can also be a chat record that matches a specific keyword. Among them, the keyword match may be an exact match or a partial match, and may be an exact match or a fuzzy match. Further, artificial intelligence can be automatically matched using a machine learning algorithm. For example, user B mentioned "How is XX handled?" At this time, the keyword "XX" can be determined, and a matching chat history can be found. If there are multiple chat records for the keyword "XX", they can be combined and displayed. For example, if the current time is Friday and there are associated chat records on Tuesday and Wednesday, the chat records on Wednesday and Tuesday can be displayed in reverse order of time. At this time, there is no time-continuous relationship between the chat records in this part of the historical chat records displayed.

In order to facilitate a person skilled in the art to more clearly understand the implementation manner of the present invention in a specific scenario, the following describes the implementation manner of the present invention by using two specific examples. It should be noted that this specific example is only to enable those skilled in the art to understand the present invention more clearly, but the embodiments of the present invention are not limited to this specific example.

3 is a flowchart of a method for processing a chat record of an instant chat tool according to another embodiment of the present invention. As shown in FIG. 3, the method may include: S301. The instant chat tool receives a new message sent by a specific user to a current user.

For example, suppose that user A receives a new message sent by user B after logging in to the instant chat tool.

S302. The instant messaging tool saves the new message in a cache and a local disk file.

It should be noted that new messages can be saved in a later storage location in the cache, marked as new messages, and saved in a local disk file at the same time. Historical messages read from a local disk file are stored in the cache's earlier storage location.

S303: In response to a user triggering a request to display a new message, read the new message from the cache, and determine whether the number or capacity of the new message is less than a set threshold; if the determination result is yes, execute S304; if the determination result is No, directly display the new message, and save the displayed message in the historical chat history cache corresponding to the specific user.

4 is a flowchart of a method for processing a chat record of an instant chat tool according to another embodiment of the present invention. As shown in FIG. 4, it may include: S401. The instant chat tool receives a new message sent by a specific user to a current user.

For example, suppose that user A receives a new message from user B after logging in to the instant chat tool.

S402. The instant messaging tool saves the new message in a cache and a local disk file.

It should be noted that new messages can be saved in a later storage location in the cache, marked as new messages, and saved in a local disk file at the same time. Historical messages read from a local disk file are stored in the cache's earlier storage location.

S403. In response to a user triggering a request to display a new message, read the new message from the cache and display the new message.

For example, when user A opens a chat session with user B, in response to the trigger operation, a cache of chat messages between user A and user B can be found from the cache, and the tag marked as read from the cache is Cache information for new messages and clear new message tags. The new message read is then displayed at the bottom of the current chat session.

S404: In response to a user triggering a request for acquiring historical chat records, determine whether the number or capacity of historical chat records saved in the cache is greater than N. If the determination result is yes, execute S405; if the determination result is no, execute S406.

S406. Read part of the historical chat records from the local disk file and save them in the cache, so that the number or capacity of the historical chat records in the cache is greater than N, and read the historical chats with the number or capacity equal to N recording.

For example, when the user clicks "View more", it can trigger loading of N historical messages. The setting of N can be performed as required. At this time, find the top message in the current session window, that is, the message displayed in the current session window that is furthest from the current time. With this message as the boundary, read N historical message records forward from the cache. . If it is determined that the history message records saved in the cache are greater than N, then the read N history records are directly displayed. If it is judged that the history message record saved in the cache is less than N, for example, the history message saved in the current cache is M, then the first message record in the cache is used as the boundary A remote record), from the local historical message record, to the record stored in the cache farthest from the current time as the boundary, read (NM) message record forward and store it in the cache. Then, taking the top message displayed in the current session window as the boundary, read N message records forward from the cache.

S407: Display the N historical chat records obtained from the cache.

5 is a flowchart of a method for processing a chat record of an instant chat tool according to another embodiment of the present invention. As shown in FIG. 5, it may include: S501, receiving an operation of a user to trigger a first control.

S502. In response to the user triggering the operation of the first control, displaying at least part of the historical chat record between the current user and the specific user; wherein each chat record in the at least part of the historical chat record does not have a time continuous relationship. Or there is no time-continuous relationship between the at least part of the historical chat record and the chat record recently displayed by the current instant chat tool.

In some implementations, the method further includes: receiving an operation triggered by the user to trigger the second control; and in response to the user triggering the operation of the second control, displaying at least part of the historical chat record between the current user and the specific user; wherein, There is a time-continuous relationship between the chat records in the at least part of the historical chat record or a time-continuous relationship between the at least part of the historical chat record and the chat record recently displayed by the current instant chat tool. Further, before displaying at least part of the historical chat record between the current user and the specific user, the method further includes: reading at least part of the historical chat record between the previous user and the specific user from the cache; wherein, the The cache stores historical chat records previously read from the local storage space and historical chat records stored directly in the cache.

In the embodiment of the present invention, it is possible to replace the method of obtaining all chat records of users in the prior art and continuously displaying the chat records in chronological order, and it is possible to obtain and display only part of the historical chat records that meet specific conditions. There is no time-continuous relationship between the chat records in the table, or there is no time-continuous relationship between the at least part of the historical chat record and the chat record recently displayed by the current instant chat tool, so as to facilitate users to obtain specific chat records. Because only a part of the historical chat history is acquired, the amount of acquired data is small, the reading speed is fast, and the efficiency of obtaining information by the user is significantly improved, and the user experience is improved.

The specific implementation manners are described in detail below.

In specific implementation, the second control and the first control can be displayed on the user interface of the instant chat tool. The second control is used to display at least part of the historical chat record between the current user and the specific user in response to the user's trigger. Each of the chat records in the at least part of the historical chat record has a time-continuous relationship or the history. The chat history has a time-continuous relationship with the recently displayed chat history of the current instant chat tool. The first control is used to display at least a part of the historical chat records that meet certain conditions between the current user and the specific user in response to the user's trigger. There is no time-continuous relationship between the chat records in the part of the historical chat records or There is no time-continuous relationship between the historical chat record and the recently displayed chat record of the current instant chat tool.

For example, the second control may be to display the latest N chat records or to display all historical chat records, and the first control may be to display related chat records. For example, if the user wants to see the historical chat history with continuous time, such as the chat history from Tuesday to Friday, he can click the second control. If the user wants to view some related chat records, the first control may be triggered. For details, see FIG. 6A.

It should be particularly noted that, in response to the user triggering the operation of the first control, reading from the cache a part of the historical chat record that meets specific conditions between the current user and the specific user may be a part of the historical chat record that meets specific conditions. The specific condition includes a history chat record that meets a specific time condition, a specific location condition, or a specific keyword. In specific implementation, instead of obtaining all chat records between the current user and a specific user and continuously displaying the chat records in chronological order, only part of the historical chat records that meet specific conditions can be obtained and displayed. For example, historical chats that meet certain time conditions. Assume that the current time is Friday, and the current user A and the specific user B are chatting through the instant chat tool. User B mentioned: "How are we doing on Tuesday?" At this time, User A is likely to want to see Tuesday ’s chat history. At this time, "Tuesday" can be identified as a keyword. Only get the historical chat history corresponding to Tuesday from the cache, and display the chat history of Tuesday in the chat interface. In this way, the chat history on Tuesday and the most recent chat history (Friday) displayed in the current window do not have a time continuous relationship. In this way, not only can you get less information, but also it is convenient for users to intuitively view the content of interest without having to have a large number of chat records (such as all chat records in the continuous time period from Friday to Tuesday) Find what you ’re interested in. As another example, the chat record may also be a chat record that meets the conditions of a specific place. Assuming that the current user frequently travels on a business trip, the login location may be changed, and the chat history of a specific place may be obtained according to the user's input. By way of example, this part of the historical chat record can also be a chat record that matches a specific keyword. Among them, the keyword match may be an exact match or a partial match, and may be an exact match or a fuzzy match. Further, artificial intelligence can be automatically matched using a machine learning algorithm. For example, user B mentioned "How is XX handled?" At this time, the keyword "XX" can be determined, and a matching chat history can be found. If there are multiple chat records for the keyword "XX", they can be combined and displayed. For example, if the current time is Friday and there are associated chat records on Tuesday and Wednesday, the chat records on Wednesday and Tuesday can be displayed in reverse order of time. At this time, there is no time continuous relationship between the chat records in the part of the historical chat records displayed.

In this embodiment of the present invention, multiple controls can be displayed in the user interface, and different display modes can be entered according to the user's trigger operation on the controls. One display mode is to display all or part of the chat history in a continuous time manner. One display mode is to display part of the chat history in a non-time continuous manner. 6B and 6C are schematic diagrams showing effects of the embodiment of the present invention. FIG. 6B is a time-continuous display mode, and FIG. 6C is a non-time-continuous display mode. The dashed line is used to separate the new chat history and the historical chat history. For example, suppose that the current user A and user B are chatting through the instant chat tool. The currently displayed chat records are new messages 103 and 104. The generation time of the message 104 is 9:31 on January 8, 2016. The message The generation time of 103 was 9:28 on January 8, 2016. In specific implementation, the second control 105 may be displayed on the display interface of the instant chat tool, such as a control that displays all chat records; and the first control 106, such as a control that displays related chat records, may be displayed.

Referring to FIG. 6B, if the user triggers the second control 105, the historical chat records of the previous user A and the user B within a continuous period of time will be read from the cache, and the chats will be displayed in sequence in chronological order. recording. As shown in FIG. 6B, if the user triggers the second control, in addition to displaying the message 103 and the message 104, the historical chat record messages 101, 102, ... 107 are further displayed. The generation time of the messages 101, 102, and 107 is continuous, that is, the chat records generated by the user retrospectively and continuously from the current time are acquired, and the display is also displayed in chronological order. Corresponding to the display method of FIG. 6B, if the user wants to view the chat history on Tuesday (ie, January 4, 2016), he needs to search in the continuous chat history traced back from the current time.

Referring to FIG. 6C, if the user triggers the first control 106, that is, the user chooses to display related chat records, the historical chat records of the former user A and the user B that meet specific conditions will be read from the cache. As shown in FIG. 6C, if the user triggers the second control, in addition to displaying message 103 and message 104, only the chat history 107 related to the current message will be displayed, that is, only the chat history of Tuesday (January 4, 2016) will be displayed. . Messages 101, 102, etc. are not displayed. Corresponding to the display manner of FIG. 6C, if the user can conveniently view the chat history of Tuesday (ie, January 4, 2016), there is no need to search for a large number of continuous chat records traced back from the current time.
