Whether step 202, the first client judge itself to the server request chat messages.
If step 203, the first client to server request chat messages, the first client terminate to After the process of server request chat messages, the first client is pulled based at least one chat messages having been received Any bar chat messages in notice pull notice and pull request to server transmission chat messages, at least one chat messages Pulling notice includes that the first chat messages pull notice.
In conclusion method for message transmission provided in an embodiment of the present invention, is receiving server by the first client After the chat messages of transmission pull notice, itself is determined whether to server request chat messages, if the first client Rectify to server request chat messages, then the first client can be at itself to server request chat messages Process after, just to server send chat messages pull request, so as to guarantee the first client every time to service The chat messages that device is sent, which pull, requests indicated timestamp all different, then avoids generation and shows to same chat messages At least twice the case where, to ensure that the validity of real-time interactive between the user of chatroom.
Fig. 3 is a kind of flow chart of method for message transmission provided in an embodiment of the present invention, and this method is applied to as shown in Figure 1 At least one server 120 in.As shown in figure 3, this method may include:
Step 301, server receive the first chat messages that the second client in chatroom is sent.
Step 302, server send the first chat messages to the first client and pull notice, which is that should chat Any client in its room in addition to second client.
Step 303, server receive at least one chat that first client is had been received based on the first client Any bar chat messages that message pulls in notice pull the chat messages that notice is sent and pull request, which disappears It includes that the first chat messages pull notice that breath, which pulls notice,.Wherein, it is first client true which, which pulls request, Fixed first client is not to sending after the server request chat messages.
In conclusion method for message transmission provided in an embodiment of the present invention, the received chat messages of server pull request It is to determine itself not to sending after server request chat messages in the first client, this can guarantee to service The chat messages that the first user end to server that device receives every time is sent, which pull, requests indicated timestamp all different, after And the case where generation shows at least twice to same chat messages is avoided, to ensure that real-time interactive between the user of chatroom Validity.
Fig. 4 A is a kind of flow chart of method for message transmission provided in an embodiment of the present invention, and this method is applied to such as Fig. 1 institute In the chat room system shown.As shown in Figure 4 A, this method may include:
Step 401, the second user end to server send the first chat messages.
Wherein, which can be any client at least one client 110 described above, the clothes Business device can be the server cluster of at least one server 120 composition.
In practical applications, if the corresponding user of the second client watch main broadcaster live streaming when want with chatroom in its His user is exchanged in real time, then the user can input a certain chat in the chat messages input frame that the second client provides Content, for example, the user can be inputted in chat messages input frame in the chat of " main broadcaster is good severe, I likes him well " Hold.Then, which can trigger the message delivery option of the second client offer, so that the second client receives chat messages Send instruction.Second client can send the first chat messages to server after receiving the chat messages and sending instruction, So that first chat messages are sent in other clients (that is to say the first client) of chatroom by server, thus Realize that the user exchanges with the real-time of the other users in chatroom.Wherein, the message content that above-mentioned first chat messages include The as chat content that is inputted in chat messages input frame of the user, for example, the message content of first chat messages can be with For " main broadcaster is good severe, I likes him well " in exemplified above, above-mentioned first client is referred in chatroom except the second visitor Any client other than the end of family that is to say appointing in addition to the second client at least one client 110 described above One client.
It, in some cases can be with it should be noted that above-mentioned first chat messages are other than comprising message content Specific limit is not done to this comprising sending other informations, the present invention such as User ID (that is to say the corresponding User ID of the second client) It is fixed.
It should also be noted that, triggering message delivery option described above is so that the second client receives chat messages hair It send the mode of instruction to be only exemplary, in practical applications, receives chat messages there are also other second clients and send The mode of instruction, the present invention no longer illustrate one by one herein.
Step 402, server receive the first chat messages that the second client is sent, based on reception first chat messages At the time of for first chat messages add timestamp, and with timestamp be index first chat messages are stored to server Memory in.
Specifically, after the first chat messages that server receives, user can be sent for the addition of the first chat messages The information such as ID (only when the first chat messages received, which do not include, sends User ID), timestamp, and with the timestamp of addition First chat messages are stored into the memory of server for index.
In practical application, server can be stored first chat messages to service after receiving the first chat messages In the memory of device, to improve the access speed of chat messages.Specifically, server first chat messages can be stored to In the storage container of Key-Value data structure, the Key-Value data structure can for TreeMap or The data structures such as ConcurrentSkipListMap, the present invention are not specifically limited in this embodiment, wherein due to ConcurrentSkipListMap data structure can use random manner ergodic data under same time complexity, Its better performances.Then server can send chat messages to the first client and pull notice, and according to the first client The first chat messages for storing server are requested to be sent to the first client.
In practical applications, server can be chatted according to the request of the first client by store in server a plurality of first Its message is successively sent to the first client, and the first client can be shown according to the sequence for receiving a plurality of first chat messages A plurality of first chat messages.In order to guarantee that the first client shows that the sequence of a plurality of first chat messages is received with server The chronological order of a plurality of first chat messages is identical, that is to say and guarantees that the first client first shows that server is first received First chat messages, rear received chat messages after showing server, thus guarantee that the displaying of the first chat messages is not out-of-order, after And guaranteeing the validity that user exchanges in real time in chatroom, server is first at the time of needs based on the first chat messages of reception Chat messages add timestamp, and with timestamp be index first chat messages are stored into server, then according to when Between stamp ascending order arrangement mode successively send a plurality of first chat messages.
For example, as shown in table 1,18:54:22:11, the 18:54:23 of server in system time on November 16th, 2016: 11,18:54:24:12 and 18:54:25:13 is respectively received the first chat messages a, the first chat messages b, the first chat messages C and the first chat messages d, wherein t:y:u:i refer to when t y divide u seconds i milliseconds.Server is based on receiving first chat messages A, the system time of the first chat messages b, the first chat messages c and the first chat messages d are first chat messages a, first Chat messages b, the first chat messages c and the first chat messages d add timestamp, and the timestamp of addition is respectively 1479293662344,1479293663344,1479293664345 and 1479293665346.Then server can be with the time Stamp stores first chat messages a, the first chat messages b, the first chat messages c and the first chat messages d to clothes for index Be engaged in device, and according to the request of the first client in such a way that timestamp ascending order arranges (ascending sequence) successively to the One client sends first chat messages a, the first chat messages b, the first chat messages c and the first chat messages d.First visitor Family end shows that first chat messages a, the first chat messages b, the chat of the first chat messages c and first disappear in the order received D is ceased, a schematic diagram of displaying is as shown in Figure 4 B, so that the first client shows first chat messages a, the first chat Message b, the sequence of the first chat messages c and the first chat messages d and server receive first chat messages a, the first chat The sequence of message b, the first chat messages c and the first chat messages d are identical, to ensure that the displaying of the first chat messages is not random Sequence then guarantees the validity that user exchanges in real time in chatroom.
Table 1

First chat messages d 2016/11/16 18:54:25:13 1479293665346
It should be noted that the system time and timestamp when above-mentioned reception are all only exemplary, it can not The limitation present invention.
It should also be noted that, the quantity for the chat messages that can be seen clearly within the unit time due to user is limited, Therefore, certain first chat messages can not issue the first client, but directly be abandoned by server, so that it is empty to save storage Between and network flow.Specifically, in one embodiment of the invention, server can obtain before storing the first chat messages Take in the memory of server in certain scheduled unit time, it is such as per second in, the quantity of the chat messages of storage, if the quantity is more than the One preset threshold, then server can be abandoned based on certain strategies while storing first chat messages and be stored in service Certain chat messages in device memory, for example, server can be when storing first chat messages by correspondent time minimum Chat messages delete;In another embodiment of the present invention, when the first chat that server receives within the unit time When the quantity of message reaches the second preset threshold, server can also disappear the first chat subsequently received in the unit time Breath abandons.Certainly, in practical applications, the strategy that server abandons chat messages can be there are many kind, and the present invention is herein no longer It repeats one by one.
In practical applications, the time of reception of timestamp reflection at most may be only accurate to a millisecond rank, and due to chatroom The coincidence that middle server receives the first chat messages is very high, that is to say, can receive in 1 millisecond of server in chatroom more The first chat messages of item, this results in that the elder generation that same millisecond server receives the first chat messages cannot be distinguished by timestamp Sequence afterwards.Further, since the first chat messages are that index is stored in storage container with timestamp, one is indexed in storage container As do not allow to repeat, therefore, there is a plurality of first chat messages same timestamp will lead to some of the in same millisecond One chat messages are lost, i.e., are not abandoned by preset message drop policy by server.
For example, server successively receives the first chat messages e in same millisecond, the first chat messages f and first is chatted Its message g, but the timestamp of first chat messages e, the first chat messages f and the first chat messages g are all 1477456674562.Therefore, it is impossible to determine that server receives first chat messages e, the first chat by the size of timestamp The sequencing of message f and the first chat messages g, moreover, server store the first chat messages e, the first chat messages f and It when the first chat messages g, is not repeated to guarantee to index in storage container, the first chat messages e and first may be abandoned and chatted Its message f, and the first chat messages g is only stored, so as to cause the loss of important messages.
The sequencing for receiving the first chat messages in same millisecond in order to Differentiated Services device takes also for guarantee Business device will not lose certain first chat messages when storing the first chat messages, i.e., do not abandon the by preset message drop policy One chat messages are the mode that the first chat messages add timestamp the present invention provides following two:
The first, server based at the time of receiving the first chat messages determine the timestamps of first chat messages, clothes Business device judges whether the timestamp of the timestamp of first chat messages and the chat messages stored in memory of server is identical, If the timestamp of first chat messages is identical as the timestamp of any chat messages stored in memory of server, change The timestamp of first chat messages, by first chat messages for changing timestamp with change after timestamp it is corresponding store to In the memory of server.
Above-mentioned " timestamp for changing the first chat messages " can be by the timestamp and preset value of first chat messages It is added etc., the present invention is not specifically limited in this embodiment, and in practical applications, timestamp after change and is stored in the memory of server The timestamps of any chat messages be different from.
It should be noted that the modification in order to avoid timestamp causes confusion, server can add thread lock to guarantee this Server can serially execute the step of timestamp for changing the first chat messages.
For example, server can be based on the timestamp for determining first chat messages g at the time of receiving the first chat messages g Be 1477456674562, then, server query service device storage each chat messages index whether be 1477456674562.By inquiry, server determines that the timestamp of the chat messages e of server storage is also 1477456674562, then the timestamp 1477456674562 of first chat messages g can be added by server with 1, be obtained The new timestamp of first chat messages g is 1477456674563, and then server continues each chat of query service device storage Whether the index of message is 1477456674563.Repeat the above process, until the first chat messages g new timestamp with The index of any chat messages of server storage is different, can then store first chat messages g to server In memory, index is the timestamp of finally obtained first chat messages g.
In another example server receives the first chat messages e, the first chat messages f and the first chat in same millisecond The timestamp of message g, first chat messages e, the first chat messages f and the first chat messages g are 1477456674562. Then, server can add thread lock to guarantee that the server can be executed serially and change first chat messages e, first chat The step of timestamp of its message f and the first chat messages g, causes confusion to avoid because of timestamp modification.Illustratively, it services Device can successively change the timestamp of the first chat messages e, the first chat messages f and the first chat messages g, make change after when Between stamp be respectively 1477456674562,1477456674563 and 1477456674564 (in practical applications, if server The timestamp of any chat messages stored in memory and the timestamp of the first chat messages e are different from, it may not be necessary to be repaired Change the timestamp of first chat messages e).
Second, server is based on determining the timestamps of first chat messages at the time of receiving first chat messages, Server judge the timestamp of first chat messages and the chat messages stored in memory of server timestamp whether phase Together, if the timestamp of first chat messages is identical as the timestamp of target chat messages stored in memory of server, clothes First chat messages and the target chat messages are merged to obtain the second chat messages by business device, and second chat messages when Between stamp be first chat messages timestamp, then server is by the time of second chat messages and second chat messages Stamp is accordingly stored into the memory of server, and deletes the target chat messages.
It should be noted that above-mentioned, " first chat messages and the target chat messages are merged to obtain second by server What chat messages " referred to can be first chat messages and target chat messages one ordered set of composition.Wherein, above-mentioned One chat messages and target chat messages include message content and other information, which may include sending user ID etc..Since the second chat messages are the ordered set that the first chat messages and target chat messages form, then the first client The first chat messages for including in second chat messages and target chat can be successively shown according to the sequence of the ordered set Message guarantees that the displaying of chat messages is not out-of-order.
Step 403, server send the first chat messages to the first client and pull notice, which is that should chat Any client in its room in addition to second client.
Server can notify the first client after receiving the first chat messages, that is to say and send to the first client First chat messages pull notice, so that the first client is asked after receiving first chat messages and pulling notice to server Seek acquisition chat messages.
Step 404, the first client judge that first client is after receiving first chat messages and pulling notice It is no to the server request chat messages.
In practical applications, the first client can send to server after receiving chat messages and pulling notice and chat Message pulls request.The chat messages, which pull request, can carry object time mark, and object time mark is used to indicate the Corresponding maximum timestamp in the chat messages that one client has been received, so that server can will be in server The chat messages for the timestamp that the timestamp for depositing middle storage is greater than object time mark instruction are sent to the first client, thus Guarantee server will not the chat messages of received mistake repeat to be sent to the first client the first client.
For example, as shown in table 2, the chat messages that the first client has been received may include chat messages u, chatting disappears It is as shown in table 2 to cease v, chat messages w and chat messages x, corresponding timestamp.According to table 2, the first client is had been received Chat messages in corresponding maximum timestamp be 1477456674568, then the first client send chat messages pull Carried in request object time mark can serve to indicate that this 1477456674568.Server is receiving chat messages drawing The chat messages that the timestamp of the memory storage of server is greater than 1477456674568 can be sent to the first visitor after taking request Family end, thus guarantee server will not the first client received mistake chat messages repeat be sent to the first client, It that is to say that server will not repeat to send chat messages u, chat messages v, chat messages w or chat messages x to the first client.
Table 2
Chat messages Timestamp
Chat messages u 1477456674562
Chat messages v 1477456674565
Chat messages w 1477456674568
Chat messages x 1477456674560
It should be noted that the timestamp of above-mentioned chat messages is only exemplary, the present invention can not be limited.
However, in practical applications, the coincidence that the second user end to server sends the first chat messages may be very Height, this result in the first client during pulling request to server request chat messages based on chat messages also The chat messages that server transmission may be received pull notice.First client pulls notice receiving the chat messages After can continue to server send chat messages pull request, due to the first client last time transmission chat messages pull Request server may respond not yet.Therefore, in this case, the chat twice that the first user end to server is sent disappears Breath pull request carry object time mark may be it is identical, this result in the first client can obtain it is duplicate chat disappear There is the case where same chat messages are shown at least twice so as to cause the first client in breath, this can seriously affect live streaming and chat The validity of real-time interactive between the user of its room.
For example, the first client has connect when the first client pulls request to server transmission chat messages for the first time The chat messages received timestamp corresponding with its can be indicated that the chat messages then sent for the first time pull request and take by table 2 The object time mark of band can indicate 1477456674568.In the server chat messages that response is sent for the first time not yet When pulling request, server can send chat messages to the first client again and pull notice, and the first client can be based on The chat messages pull notice and pull request to second of transmission chat messages of server.Since server does not respond to the first visitor The chat messages that family end is sent for the first time pull request, then the chat messages that the first client has been received at this time and its correspondence Timestamp still can indicate that then second chat messages sent pull object time mark that request carries still by table 2 Instruction 1477456674568.Server responds the chat messages that the first client is sent for the first time and pulls request, can will service Chat messages of the timestamp greater than 1477456674568 of device storage are sent to the first client, and server responds the first client Second of the end chat messages sent pull request, and the timestamp that can still store server is greater than 1477456674568 Chat messages are sent to the first client, duplicate chat messages can be obtained so as to cause the first client, so as to cause first There is the case where same chat messages are shown at least twice in client, and as shown in Figure 4 C, this can seriously affect chatroom user Between real-time interactive validity.
In order to avoid above situation, the first client can be sentenced after receiving above-mentioned first chat messages and pulling notice Whether first client of breaking that is to say to the server request chat messages, judge whether server has rung The chat messages for having answered the first user end to server history to send pull request.The chat messages that the history is sent pull request The chat messages that can be sent for the first user end to server in the preset time period before current time pull request, can also The first client last time pulls request to the chat messages that server is sent before thinking current time, the present invention to this not It is specifically limited.Specifically, the first client can detecte the feedback information for itself whether receiving server transmission, the feedback Information, which is server, to be pulled request based on the chat messages that the first client history is sent and sends to first client, if First client receives the feedback information, it is determined that first client is not disappearing to server request chat Breath;If the first client does not arrive the feedback information, it is determined that first client is chatted to the server request Message.
In practical applications, which can pull the chat that request is sent based on chat messages for server and disappear Breath, or pull error message, this, which pulls error message, to be a null value, in this way can be to avoid " the card of client " generation of phenomenon.
If step 405, the first client to server request chat messages, terminate in first client To after the process of server request chat messages, the first client is drawn based at least one chat messages having been received It takes any bar chat messages in notice to pull notice and pulls request to server transmission chat messages, which disappears It includes that first chat messages pull notice that breath, which pulls notice,.
As described above, in the first client to server request chat messages when, the first client is to service Device transmission chat messages, which pull request, will lead to the duplicate chat messages of the first client acquisition.Therefore, rectify in the first client When to server request chat messages, the first client itself can terminate to server request chat messages Process after send chat messages to server and pull request, which, which pulls request and carry above-mentioned object time, identifies. Certainly, in practical applications, if first client is not to server request chat messages, the first client Chat messages directly can be sent to server pull request.
It should be noted that above-mentioned first client terminates to the process of server request chat messages to be the One client determines that server has had responded to the chat messages that the first client history is sent and pulled request, that is to say, first Client has received above-mentioned feedback information.
It should also be noted that, the first client to server request chat messages during, first The a plurality of chat messages that client is likely to be received server transmission pull notice, that is to say that described above " at least one chats Its message pulls notice ", then terminate after the process of server request chat messages in the first client, the first client Can be based only upon at least one chat messages pull notice in any bar chat messages pull notice to server transmission chat Its message pulls request, and abandons remaining chat messages and pull notice.Wherein, any bar chat messages pull notice can be with Notice is pulled for the chat messages that the first client receives for the last time before current time, or described above First chat messages pull notice, and the present invention is not specifically limited in this embodiment.
Step 406, server disappear after receiving the chat messages that first client is sent and pulling request according to the chat Breath pulls request and sends chat messages to the first client.
As described above, the timestamp that server stores can be greater than chat messages by server pulls the target that request carries The chat messages of the timestamp of time identifier instruction are sent to the first client.
In conclusion method for message transmission provided in an embodiment of the present invention, is receiving server by the first client After the chat messages of transmission pull notice, itself is determined whether to server request chat messages, if the first client Rectify to server request chat messages, then the first client can be at itself to server request chat messages Process after, just to server send chat messages pull request, so as to guarantee the first client every time to service The chat messages that device is sent, which pull, requests indicated timestamp all different, then avoids the first client and disappears to same chat The case where breath is shown at least twice, to ensure that the validity of real-time interactive between the user of chatroom.
