However, information interaction based on the Internet also has drawbacks.

[0060] Optionally, in the embodiments of the present application, the above information interaction method can be applied to a hardware environment composed of a first interaction terminal 101, a server 103, and a second interaction terminal 105 as shown in Figure 1 As shown, the server 103 is connected to the first interaction terminal 101 and the second interaction terminal 105 through a network, and can be used to provide services (such as information interaction services) for the interaction terminal or the client installed on the interaction terminal.

A database 107 can be set on the server or independently of the server to provide data storage services for the server 103. The above network includes but is not limited to: wide area network, metropolitan area network, or local area network. The first interaction terminal 101 and the second interaction terminal 105 include but are not limited to PCs, mobile phones, tablet computers, etc.

[0061] The information interaction method includes:

[0062] Step 1, when the first interaction terminal establishes a connection with the server, it sends a calibration information request to the server;

[0063] Step 2, when the server receives the calibration information request sent by the first interaction terminal, it returns first calibration information to the first interaction terminal, where the first calibration information is used to determine the manner of generating a calibration sequence in the current connection;

[0064] Step 3, the first interaction terminal receives the first calibration information returned by the server in response to the calibration information request, and replaces the second calibration information used in the previous connection with the first calibration information, where different calibration information is used to determine the manner of generating a calibration sequence in different connections;

[0065] Step 4, each time the first interaction terminal sends interaction information to the server under the current connection, it generates a corresponding calibration sequence for each interaction information according to the first calibration information, and sends the interaction information carrying the calibration sequence;

[0066] Step 5, when the server receives the interaction information sent by the first interaction terminal, it sorts the interaction information using the calibration sequence carried in the interaction information and updates the calibration sequence;

[0067] Step 6, the server forwards the sorted interaction information to the second interaction terminal, and returns the updated calibration sequence to the first interaction terminal; and maps and stores the updated calibration sequence and the interaction information;

[0068] Step 7, the second interaction terminal receives and displays the interaction information.

[0069] To describe the technical solution of the present application more clearly and in detail, the following will be described separately for each end.

[0070] In the embodiment of the present application, the information interaction method executed by the first interaction terminal 101, as Figure 2 shown, this method may include the following steps:

[0071] Step S202, when establishing a connection with the server, send a calibration information request to the server;

[0072] Step S204, receive the first calibration information returned by the server in response to the calibration information request, and replace the second calibration information used in the previous connection with the first calibration information, where different calibration information is used to determine the manner of generating a calibration sequence in different connections; and

[0073] Step S206, each time the interaction information is sent to the server under the current connection, generate a corresponding calibration sequence for each interaction information according to the first calibration information, and send the interaction information carrying the calibration sequence, so that the server sorts the interaction information using the calibration sequence and forwards the sorted interaction information to the second interaction terminal.

[0074] Through the above steps S202 to S206, when the present application establishes a connection with the server through the interaction terminal, calibration is performed, and each interaction message sent by the interaction terminal carries a calibration sequence, so that the server can sort the interaction messages sent by the interaction terminal according to the calibration sequence, and can timely adjust the order of the interaction messages according to the calibration sequence in the case of out-of-order interaction messages, so that all the interaction messages exchanged between the interaction terminals maintain the same order, and the technical problem of inconsistent information order between information interaction parties caused by changes in the network environment is solved.

[0075] In the embodiment of the present application, the first interaction terminal is the sender of interaction messages between multiple interaction terminals, and the second interaction terminal is the receiver of interaction messages between the multiple interaction terminals. The same interaction terminal can be used as both the first interaction terminal and the second interaction terminal.

[0076] In step S202, each time the interaction terminal establishes a connection with the server, it needs to send a calibration information request to the server, and the server will return the calibration information dedicated to this connection.

[0077] In step S204, since the above first calibration information is the calibration information dedicated to this connection returned by the server in response to the calibration information request, it is necessary to replace the second calibration information used in the previous connection with the first calibration information used in this connection.

[0078] In step S206, each interaction message sent by the first interaction terminal in this connection generates a corresponding calibration sequence according to the above first calibration information, and the corresponding calibration sequence is carried when sending the interaction message. This calibration sequence represents the sending order of all the interaction messages sent by the first interaction terminal. When the server receives each interaction message, it extracts the calibration sequence to determine the position of the just-received interaction message. Normally, the sorting result of the interaction messages according to the calibration sequence is at the end of the information list. If the interaction messages are out of order due to network instability, network latency, etc., for example, the first interaction terminal sequentially sends interaction message A and interaction message B, and the order received by the server is interaction message B and interaction message A. At this time, the server can sort the interaction messages according to the calibration sequence and then forward the sorted interaction messages to the second interaction terminal to ensure that all the interaction messages exchanged between the interaction terminals maintain the same order.

[0079] Optionally, in step S206, generating a corresponding calibration sequence for each interaction message according to the first calibration information includes:

[0080] Step 1, extract the synchronization clock embedded by the server from the first calibration information, where the synchronization clock is synchronized with the server's own clock;

[0081] Step 2, determine the client sequence of the interaction information by using the synchronous clock, where the client sequence includes at least one of the sending timestamp, sending serial number, and information verification code of the interaction information; and,

[0082] Step 3, generate a calibration sequence by using the first server sequence, connection establishment time, and client sequence, where the first server sequence is the server sequence returned by the server stored locally in the first interaction terminal for the last time, and the server sequence is the sequential sequence assigned by the server to each interaction information sent to the first interaction terminal.

[0083] In the embodiment of the present application, the first calibration information returned by the server is used to determine the method of generating the calibration sequence in this connection. First of all, it is clock synchronization. The server embeds the synchronous clock that is completely synchronized with its own clock into the first calibration information. After the first interaction terminal extracts the synchronous clock, it uses the synchronous clock to record time throughout this connection, avoiding the situation that the calibration sequence generated according to the first calibration information is incorrect due to the asynchronous clock between the local clock of the first interaction terminal and the server clock. Based on this synchronous clock, the first interaction terminal can determine the client sequence clientSeq, and the client sequence can include the sending timestamp, sending serial number, and information verification code of the interaction information recorded based on this synchronous clock, device identification, user identification, and other identification features.

[0084] The first interaction terminal can also determine the connection establishment time between the first interaction terminal and the server based on this synchronous clock. The time when the first interaction terminal initiates the connection can be used as the connection establishment time, or the time when the server sends the first calibration information can be used as the connection establishment time. Among them, when the time when the first interaction terminal initiates the connection is used as the connection establishment time, the connection establishment time based on the synchronous clock can be determined based on the time difference between this synchronous clock and the local clock of the first interaction terminal; when the time when the server sends the first calibration information is used as the connection establishment time, when the server returns the first calibration information, the connection establishment time is carried.

[0085] The server can also assign a server sequence serverSeq to each interaction information sent by the first interaction terminal to record the order of the interaction information. Under normal network conditions, the order of the interaction information sent by the first interaction terminal is the same as the order of the interaction information received by the server. The order of the server sequence assigned by the server to each interaction information is the same as the order of receiving the interaction information, and the server sequence increases. In the case of unstable network, network delay, etc., due to out-of-order messages, the server can first sort the interaction information according to the calibration sequence. When it is detected that there are out-of-order messages, a new server sequence is re-assigned to the out-of-order messages, so that the increasing order of the server sequence of the interaction information is consistent with the order of the interaction information sent by the first interaction terminal.

[0086] In the embodiment of the present application, the first interaction terminal may generate a calibration sequence for this interaction message by using the above client sequence, connection establishment time, and server sequence. However, since this interaction message is newly sent and the server has not received it and assigned a server sequence for it, the first server sequence assigned by the server for the previous interaction message needs to be used to generate the calibration sequence for this interaction message. Of course, after the server receives the interaction message and assigns a server sequence for it, it will return the newly assigned server sequence to the first interaction terminal for storage, so as to generate the calibration sequence for the next interaction message. That is, after the first interaction terminal sends an interaction message carrying the calibration sequence, the method further includes:

[0087] Step 1, receive the second server sequence returned by the server in response to the interaction message, and replace the first server sequence in the calibration sequence corresponding to the interaction message with the second server sequence to keep the sequence in the server synchronized, where the second server sequence is the sequential sequence assigned by the server for the interaction message; and,

[0088] Step 2, store the updated calibration sequence and the second server sequence.

[0089] In the embodiment of the present application, the second server sequence is the latest server sequence assigned by the server for this interaction message. After obtaining the second server sequence, the first interaction terminal needs to update the calibration sequence of this message, that is, replace the first server sequence with the second server sequence. The server performs the same operation, so that the server sequence increases, and the calibration sequences on the first interaction terminal and the server are kept consistent.

[0090] In the present application, calibration is performed when the interaction terminal and the server establish a connection, and each interaction message sent by the interaction terminal carries a calibration sequence, so that the server can sort the interaction messages sent by the interaction terminal according to the calibration sequence, and can timely adjust the order of the interaction messages according to the calibration sequence in the case of out-of-order interaction messages, so that all the interaction messages exchanged between the interaction terminals are kept in the same order, solving the technical problem of inconsistent information order between information interaction parties caused by changes in the network environment.

[0091] In the embodiment of the present application, the information interaction method executed by the server 103, as Figure 3 shown, the method may include the following steps:

[0092] Step S302, in the case of receiving a calibration information request sent by the first interaction terminal, return the first calibration information to the first interaction terminal, where the first calibration information is used to determine the method of generating the calibration sequence in the current connection;

[0093] Step S304, when receiving the interaction information sent by the first interaction terminal, sort the interaction information by using the calibration sequence carried in the interaction information, and update the calibration sequence;

[0094] Step S306, forward the sorted interaction information to the second interaction terminal, and return the updated calibration sequence to the first interaction terminal; and,

[0095] Step S308, map and store the updated calibration sequence and the interaction information.

[0096] Through the above steps S302 to S308, when the present application establishes a connection through the interaction terminal and the server, calibration is performed, and each piece of interaction information sent by the interaction terminal carries the calibration sequence, so that the server can sort the interaction information sent by the interaction terminal according to the calibration sequence, and can timely adjust the order of the interaction information according to the calibration sequence in the case of out-of-order interaction information, so that all the interaction information exchanged between the interaction terminals maintains the same order, and solves the technical problem that the information order between information interaction parties is inconsistent due to changes in the network environment.

[0097] In step S302, the first calibration information is specifically used to determine the manner in which the first interaction terminal generates the calibration sequence for each piece of interaction information in this connection. The first calibration information may include the synchronization clock of the server itself. After the first interaction terminal extracts the synchronization clock, it uses the synchronization clock to record time throughout this connection, so as to avoid the situation that the calibration sequence generated according to the first calibration information is incorrect due to the out-of-synchronization between the local clock of the first interaction terminal and the server clock.

[0098] In step S304, sorting the interaction information by using the calibration sequence carried in the interaction information and updating the calibration sequence includes:

[0099] Step 1, extract the connection establishment time from the calibration sequence according to a preset rule, where the preset rule includes the location and character length of the connection establishment time;

[0100] Step 2, regard the interaction information with the same connection establishment time as the same group of interaction information, and sort the interaction information based on the group according to the connection establishment time;

[0101] Step 3, in the same group of interaction information, extract the client sequence from the calibration sequence according to a preset rule, and sort the interaction information in the same group according to the client sequence, where the preset rule includes the location and character length of the client sequence; and,

[0102] Step 4: According to the sorting order of the interaction information, assign a corresponding server sequence to each piece of interaction information, and replace the original server sequence in the calibration sequence with the newly assigned server sequence, where the server sequences increase in the sorting order.

[0103] In the embodiment of the present application, the preset rule corresponds to the first calibration information, including the composition settings of all calibration sequences in this connection, such as the location and character length of the connection establishment time, the location and character length of the client sequence, etc. The server first extracts the connection establishment time from the calibration sequence according to the preset rule, groups the interaction information according to the connection establishment time, and regards the interaction information with the same connection establishment time as the same group of interaction information. Multiple groups are sorted in the order of the connection establishment time. In the same group, the server extracts the client sequence from the calibration sequence according to the preset rule to sort the interaction information within the group. Since the client sequence includes information such as the sending timestamp and sending serial number of the interaction information determined based on the synchronous clock, the server can obtain the same sorting order as the order in which the first interaction terminal sends the interaction information after sorting the interaction information according to these information. Finally, the server assigns a corresponding server sequence to each piece of interaction information according to the sorting order of the interaction information, and replaces the original server sequence in the calibration sequence with the newly assigned server sequence.

[0104] Optionally, the sorting of the interaction information can determine the sorting range through a time window. For example, if the time window is 1 minute, after the server receives new interaction information, it sorts the new interaction information with all the interaction information received within 1 minute. This time window can be set as needed. If the sorting result shows that there is out-of-order interaction information, reassign the server sequence to the out-of-order interaction messages according to the re-sorted order.

[0105] In step S304, forwarding the sorted interaction information to the second interaction terminal includes:

[0106] Step 1: Send the latest server sequence to the second interaction terminal so that the second interaction terminal can determine the sequence difference between the locally existing server sequence and the latest server sequence; and

[0107] Step 2: When receiving an information acquisition request sent by the second interaction terminal for the sequence difference, determine the interaction information corresponding to the sequence difference;

[0108] Step 3: Return the interaction information to the second interaction terminal.

[0109] In the embodiments of the present application, after the server sorts the interaction information, an information list that is exactly the same as the order in which the first interaction terminal sends the interaction information is obtained. Each interaction information is assigned a server sequence number that increases sequentially according to the sending order. The server can send the latest server sequence number in the information list to the second interaction terminal, so that the second interaction terminal can determine the sequence difference between the server sequence number that already exists locally and the latest server sequence number, and then the second interaction terminal can fetch the interaction information corresponding to the sequence difference from the server. The interaction information fetched by the second interaction terminal is also displayed according to the server sequence number. Therefore, the information lists on the first interaction terminal, the server, and the second interaction terminal are exactly the same.

[0110] The above server sequence numbers can be pre-generated, and when a new interaction information is received, a pre-generated server sequence number is assigned to the interaction information according to the sorting order, as long as it is ensured that the numbers increase sequentially. It is also possible to newly generate server sequence numbers for the sorted interaction information when a new interaction information is received. The above latest server sequence number sent by the server to the second interaction terminal can be the latest assigned one or the latest generated one.

[0111] Optionally, after forwarding the sorted interaction information to the second interaction terminal, the method further includes:

[0112] Step 1, when the connection establishment time of the newly received interaction information is less than the connection establishment time of the stored interaction information and / or the client sequence number of the newly received interaction information is less than the client sequence number of the stored interaction information, re-sort the interaction information according to the connection establishment time and / or the client sequence number, and re-assign server sequence numbers to the re-sorted interaction information;

[0113] Step 2, determine the smallest server sequence number at which the re-sorted interaction information has changed;

[0114] Step 3, send a server sequence number discard instruction to the second interaction terminal, so that the second interaction terminal discards the server sequence numbers and information that are greater than or equal to the smallest server sequence number; and,

[0115] Step 4, send the latest server sequence number after re-sorting to the second interaction terminal, so that the second interaction terminal can determine the sequence difference between the server sequence number that already exists locally and the latest server sequence number, and fetch the interaction information corresponding to the sequence difference from the server.

[0116] In an embodiment of the present application, if the connection establishment time in the calibration sequence of the newly received interaction information is less than the connection establishment time of the stored interaction information, the interaction information is excluded from the sorting range of the current connection, and the new interaction information is sorted in the actual information group. If the client sequence in the calibration sequence of the newly received interaction information is less than the client sequence of the stored interaction information, re-sorting is performed in the information group of the current connection, and a new server sequence is re-assigned to the interaction information after re-sorting. The server determines the minimum server sequence of the interaction information whose order has changed after re-sorting, and sends a server sequence discard instruction to the second interaction terminal, so that the second interaction terminal discards the server sequences and information greater than or equal to the minimum server sequence, and finally sends the latest server sequence after re-sorting to the second interaction terminal, so that the second interaction terminal determines the sequence difference between the locally existing server sequence and the latest server sequence, and pulls the interaction information corresponding to the sequence difference from the server.

[0117] Optionally, the server may include a server cluster composed of a primary server and a secondary server. When the primary server executes the above method steps, they are synchronized to the secondary server to form a master-slave synchronization. Thus, when the primary server fails and cannot continue to provide services, the secondary server can immediately continue to provide services. For example, when the primary server and the secondary server synchronize the server sequences, when the primary server fails, the secondary server continues to assign new server sequences to the interaction information sent by the first interaction terminal based on the synchronized server sequences, and notifies the second interaction terminal to pull the interaction information corresponding to the latest server sequence.

[0118] In the present application, calibration is performed when the interaction terminal establishes a connection with the server, and each interaction information sent by the interaction terminal carries a calibration sequence, so that the server can sort the interaction information sent by the interaction terminal according to the calibration sequence, and can timely adjust the order of the interaction information according to the calibration sequence in the case of out-of-order interaction information, so that all the interaction information exchanged between the interaction terminals maintains the same order, solving the technical problem of inconsistent information order between information interaction parties caused by changes in the network environment.
