Detailed Description

In order that the above-recited objects, features and advantages of the present invention will become more readily apparent, a more particular description of the invention will be rendered by reference to the appended drawings and appended detailed description.

Referring to fig. 1, a flowchart of steps of an offline message transmission method provided in an embodiment of the present invention is shown, where the flowchart is applied to a server, and the server is communicatively connected to at least one client, and may specifically include the following steps:

Step 101, receiving and storing a message sent by any user through the client and a version number corresponding to the message;

The embodiment of the invention can realize the roaming of the message under the condition that the user uses multiple devices, and can store the message generated in the instant messaging service. Meanwhile, each message can also have a unique version number, and the version number can be distributed to the message by the server after the server obtains the message, and meanwhile, the version numbers are stored together.

In the process of using the instant messaging service, the user can send messages to other users through the client of the instant messaging service held by the user, and can also receive messages sent by other users through the client. The client can upload the message to be sent to the server, and the message is forwarded to the client of the corresponding user by the server. Thus, the server can receive the message sent by any user through the client. Thereafter, the server may generate unique version numbers for the messages, respectively, and store both the messages and the version numbers corresponding to the messages.

Step 102, for any one of the clients, receiving a message synchronization request sent by the client when the client is online; the message synchronization request records a user identification and a first version number of the latest message stored locally by the client;

For any client, if the user accesses the server through the client itself to obtain the instant messaging service, the client can be considered to log on. At this time, in the offline process from the last online of the client to the current online login, the user may access the instant messaging service through other clients, receive and/or send the message, and the client is in an offline state, and does not acquire the information, so that the history message is missing. In order to acquire the missing history message, the client may send a message synchronization request to the server when the client is online, so as to request to acquire a message generated in an offline process.

In particular, the message synchronization request may be documented with a user identification so that the server may look up a message generated for the user based on the user identification, including a message sent to the user, as well as a message sent by the user.

The message synchronization request may record a first version number of a latest message stored locally by the client to inform the server of the latest message currently stored by the client, facilitating the server to determine a missing message for the client.

Step 103, searching a target offline message generated later than the message corresponding to the first version number based on the version number in the message corresponding to the user identifier;

in a specific implementation, the message may be associated with a user identification. If the message is a message sent by a user or a message received by the user, the message may be associated with a user identification of the user. Therefore, the server can search the message generated for the user according to the user identification as the message corresponding to the user identification. The messages can form a message queue which is arranged according to time sequence based on the version numbers, therefore, the server can search the messages which are generated later than the messages corresponding to the first version numbers in the messages corresponding to the user identification based on the version numbers, namely, the messages which are not synchronized to the client in the offline process of the client, so as to obtain the target offline messages.

And 104, transmitting the target offline message to the client.

And then, the target offline message can be issued to the client, so that the client can acquire the message generated by the user in the offline process, and multi-terminal synchronization of the message is realized. The client can store the message locally, and even if the server subsequently deletes the stored message, the client can retain the user's message, so that the user can view his history message on any client.

In one embodiment of the present invention, the step of searching for the target offline message generated later than the first version number corresponding message in the messages corresponding to the user identification based on the version number comprises

S11, searching a second version number of the latest message corresponding to the user identifier in the message stored by the server;

In particular implementations, the server may confirm whether the client has an unsynchronized offline message. Thus, the server may first look up the second version number of the latest message to which the user identification corresponds from among the messages it stores.

In a specific implementation, the server may store the version numbers corresponding to the user identifiers in time sequence. For example, the information in the version number may be associated with time, so that the server may sort it by time directly based on the information in the version number associated with time. For another example, when the server stores a message, the server may further record a timestamp corresponding to the message, and then the server may sort the version numbers by time based on the timestamp of the version number corresponding to the message.

Then, due to the one-to-one correspondence between the messages and the version numbers, the version number with the latest time is generated in the version numbers in time sequence, namely the version number corresponding to the latest message is used as the user identifier, and the version number is used as the second version number.

S12, comparing whether the first version number is the same as the second version number;

Thereafter, the first version and the second version numbers may be compared to determine whether the message locally stored at the client has been synchronized with the message stored at the server. If the first version is the same as the second version, the client can be considered that no new message is generated in the offline process, and at the moment, the message stored locally by the client is the same as the message stored by the server, and the client and the server are in a synchronized state, so that no offline message needs to be acquired. If the first version is different from the second version, the client can be considered to generate a new message in the offline process, and the message stored locally by the client is different from the message stored by the server, so that the client needs to acquire the offline message to synchronize with the server.

And S13, if the first version number is different from the second version number, searching a target offline message generated later than the first version number corresponding message in the user identification corresponding message based on the version number.

If the first version number is different from the second version number, the client needs to acquire the message generated in the offline process. Specifically, the messages corresponding to the user identifiers may also be arranged according to a time sequence, and the server may determine the messages corresponding to the first version number first, and use the messages with a time sequence later than that of the messages corresponding to the first version number as the messages to be synchronized, so as to obtain the target offline message. The server may determine a target version number generated later than the first version number among the version numbers arranged in time sequence, and extract a corresponding message based on the target version number to obtain a target offline message.

In addition, the message synchronization request may also have a time stamp of the sending request time, so that the server processes the message synchronization request from at least one client according to the actual requirement and in time sequence.

In one embodiment of the present invention, the message synchronization request further records a device identifier;

the method further comprises the steps of:

S21, creating a device online state table; the equipment online state table is used for recording the user identification of the user, and the equipment identification and online state of the client held by the user;

In a specific implementation, in order to better manage multiple clients of a user, synchronization of messages is enabled to be more real-time and accurate. Whether the client of the user is online or not can be managed. Thus, a device presence table is possible. The device presence table may record a user identifier of a user, and a device identifier of a client held by the user, and may record a presence of the client.

And S31, based on the equipment identification recorded in the message synchronization request, updating the online state of the client corresponding to the equipment identification in the equipment online state table to be online.

In the event that a message synchronization request sent when a client comes online is received, the server may determine that the client is going from offline to online. Therefore, the server can acquire the equipment identification recorded in the message synchronization request, and update the online state of the equipment identification corresponding to the client in the online state table of the equipment to be online, so that the equipment in the online state can be managed later.

Optionally, the method further comprises:

S41, under the condition that a message generated for a target user is received, a version number update notification is sent to a target online client corresponding to the target user; the target online client is a client with online state corresponding to a target user in the equipment online state table;

Specifically, for a target user, if the server receives a message generated for the target user, that is, a message sent by the target user, or the target user receives a message sent by another user. In order to keep the information synchronization of a plurality of online clients, the client corresponding to the target user can be searched in the online state table of the device, and the client with online state is extracted from the client corresponding to the target user as the target online client. And sending a version number update notification to the target online client to inform the current online client that an updated message exists.

S42, receiving a message synchronization request sent by the target online client based on the version number update notification;

For the target online client, after receiving the version number update notification, the target online client may request the server to issue the latest message, so that the target online client may generate a message synchronization request in response to the version number update notification. The message synchronization request may be similar to a message synchronization request sent on-line, in which a user identifier is recorded, and a first version number of a latest message stored locally by the client, so that the server searches for an offline message that is not synchronized by the client.

S43, based on the message synchronization request, the message generated for the target user is issued to the target online client.

The server may search for a message generated for the user according to the user identifier, as a message corresponding to the user identifier. The messages can form a message queue which is arranged according to time sequence based on the version numbers, therefore, the server can search the messages generated later than the messages corresponding to the first version numbers in the messages corresponding to the user identifications based on the version numbers, obtain updated messages generated aiming at the target users, and send the messages generated aiming at the target users to the target online clients, so that the synchronization of the messages is realized.

Alternatively, the message may have a read status, which may include read and unread. When the message generated for the target user is issued to the target online client, the reading state of the message can be further issued. If the user has read the message at a certain client, the reading state of the message is changed from unread to read, the client can send the read state of the message to the server, and the server can further synchronize the read state to other online clients of the user, so that the real-time performance of the message synchronization is further improved.

In one embodiment of the invention, the method further comprises:

s51, establishing communication connection with an online client in a long connection mode; the online client is a client with online state in the online state table of the equipment;

In particular, to more efficiently transfer messages, a communication connection is established between a server and an online client by way of a long connection. For example, a long connection between a server and an online client may be established through WebSocket protocol. Thus, clients in the device presence table whose presence is online can always remain in communication with the server.

S52, if the online state is detected to be that the online client is disconnected from communication, updating the online state of the online client to be offline in the equipment online state table;

If the client is offline, i.e. changes from online to offline, the client may be disconnected from the server. Thus, the server can detect whether the client with the online state is disconnected from the communication connection, so as to confirm whether the client is offline. If the client with the online state being online is detected to disconnect the communication connection, the client can be considered to be offline, and the online state needs to be converted into offline. The server may update the presence status of the presence client to offline in the device presence status table.

And S53, stopping sending the version number update notification to the client with the offline online state.

Because the offline client can no longer need real-time synchronous information, the server can stop sending the version number update notification to the client with the offline online state, thereby avoiding wasting processing resources.

s61, merging and compressing the target offline message to obtain a compressed offline message;

in a specific implementation, if the client is not online for a long time, a large number of unsynchronized offline messages may be generated, and if the offline messages are directly issued to the client one by one, the client may be blocked, and at the same time, processing resources of the server may be wasted. For this purpose, the target offline message may be first combined and compressed before being delivered, so that at least one of the target offline messages is compressed into a data packet, resulting in a compressed offline message.

And S62, the compressed offline message is issued to the client.

And then, the server can send the compressed offline message to the client, so that the network transmission time and the user traffic consumption can be reduced, and the transmission efficiency of the message can be improved.

Referring to fig. 2, a flowchart of steps of an offline message transmission method provided in an embodiment of the present invention is shown, where the offline message transmission method is applied to a client, and the client is communicatively connected to a server, where the method specifically may include the following steps:

Step 201, when the client is online, sending a message synchronization request to a server; the message synchronization request records a user identification and a first version number of the latest message stored locally by the client;

Step 202, receiving a target offline message issued by a server; and the target offline message is a message generated later than the message corresponding to the first version number in the messages corresponding to the user identification stored in the server.

According to the offline message transmission method provided by the embodiment of the invention, when the client is online, a message synchronization request is sent to a server; the message synchronization request records a user identification and a first version number of the latest message stored locally by the client; receiving a target offline message issued by a server; and the target offline message is a message generated later than the message corresponding to the first version number in the messages corresponding to the user identification stored in the server. Therefore, the synchronization of multiple clients of the message can be realized based on the version number of the message, and the information is stored locally at the client, so that a user can view the complete historical message at any client, and the use convenience of the user is improved.

In one embodiment of the present invention, the message synchronization request further records a device identifier. The server can update the online state of the device identifier corresponding to the client to online in the online state table of the device according to the device identifier, so that the device in the online state can be managed later.

In one embodiment of the present invention, the method further comprises:

Receiving a version number update notification sent by a server under the condition that the online state of the client is online; the version number update notification is sent to a target online client corresponding to a target user; the target online client is a client with online state corresponding to the target user; based on the version number update notification, sending a message synchronization request to the server; and acquiring a message which is issued by the server and is generated aiming at the target user.

Specifically, for a target user, if the server receives a message generated for the target user, that is, a message sent by the target user, or the target user receives a message sent by another user. In order to keep the information synchronization of a plurality of online clients, the client corresponding to the target user can be searched in the online state table of the device, the online state of the client corresponding to the target user is extracted, and a version number update notification is sent to inform the current online client of the updated information.

And under the condition that the online state of the client is online, the version number update notification sent by the server can be received. Thereafter, the client may generate a message synchronization request in response to the version number update notification. The message synchronization request may be similar to a message synchronization request sent on-line, in which a user identifier is recorded, and a first version number of a latest message stored locally by the client, so that the server searches for an offline message that is not synchronized by the client.

The server may search for a message generated for the user according to the user identifier, as a message corresponding to the user identifier. The messages can form a message queue which is arranged according to time sequence based on the version numbers, therefore, the server can search the messages generated later than the messages corresponding to the first version numbers in the messages corresponding to the user identifications based on the version numbers, obtain updated messages generated aiming at the target users, and send the messages generated aiming at the target users to the client side, so that the synchronization of the messages is realized.

In one embodiment of the present invention, the client establishes a communication connection with the server through a long connection after being online.

In particular, to more efficiently transfer messages, a communication connection is established between a server and an online client by way of a long connection. Meanwhile, the server can also determine whether the client is still online according to whether the communication connection is disconnected or not.

In one embodiment of the present invention, the step of receiving the target offline message sent by the server includes:

Receiving compressed offline messages issued by a server; decompressing the compressed offline message to obtain at least one item of marked offline message.

In a specific implementation, if the client is not online for a long time, a large number of unsynchronized offline messages may be generated, and if the offline messages are directly issued to the client one by one, the client may be blocked, and at the same time, processing resources of the server may be wasted. For this purpose, before the target offline message is issued, the target offline message may be first combined and compressed, so that at least one of the target offline messages is compressed into a data packet, and the compressed offline message is obtained and issued to the client.

After obtaining the compressed offline message, the client can decompress the compressed offline message to obtain at least one unsynchronized target offline message, thereby realizing the synchronization of the messages.

As a specific example of the present invention, fig. 3 is a schematic flow chart of an offline message transmission method provided in an embodiment of the present invention.

Step 1: the equipment 4 held by the user B is online, and a message synchronization request is sent to a gateway of the server;
