A kind of method and device realizing message and pulling provided in an embodiment of the present invention, long connection server receive next spontaneousThe instant message is stored in local by the instant message of sending end, is distributed version number to the instant message, is received from receiving endMessage acquisition request, the maximum message version number comprising local message received in the request, long connection server, which receives, to disappearAfter ceasing acquisition request, the message for being greater than maximum message version number is collected from stored instant message, is disappeared collectedBreath is pushed to receiving end.The technical method provided through the embodiment of the present invention, can or switching live streaming not online in receiving endBetween when, directly carry out the phenomenon that message pulls, avoids the occurrence of information drop-out from long connection server.
It should be noted that those skilled in the art, what above-mentioned message pulled expression is in IM (InstantMessaging, instant messaging) in service process, server end and client can carry out the interaction of message, for example, direct broadcasting roomChat messages between middle different user and main broadcaster, client can actively from server end pull client needed for message.
The embodiment of the invention provides a kind of methods realizing message and pulling, as shown in Figure 1, being applied in direct broadcasting roomWhen Communications service in, can specifically include following steps:
Step 101, long connection server receives the instant message from transmitting terminal, and received instant message is storedIn local, version number is distributed to the instant message.
In this step, when long connection server receives the instant message from transmitting terminal, long connection server willThe instant message is stored in local, and distributes corresponding version number to the instant message.
Specifically, realizing the transmission interaction of information by communication connection between long connection server and transmitting terminal.Connect when longWhen connecing server and receiving the instant message from transmitting terminal, it is local right which can be stored in by long connection serverIn the memory space answered, even and if generating corresponding version number for message is somebody's turn to do.For example, a certain user is watching certain using mobile phoneWhen live streaming, an instant message is had sent, which is equivalent to above-mentioned transmitting terminal, and server corresponding to the live streaming is equivalent toState long connection server.Therefore, it when the corresponding server of above-mentioned live streaming receives the instant message of user transmission, can incite somebody to actionThe instant message is stored in local memory space, and distributes corresponding version number.It wherein, can about the distribution of version numberSpecifically to be distributed according to the attributive character of each instant message, for example, a certain instant message is user in 10:30It sends, and is the 1st article of instant message at the time point, corresponding version number can be 10H30M1, similarly, 10H30M2The 2nd article of instant message occurred when that indicate is 10:30；Or the message is the 123rd message of today, version number can be withIt is No.123.Since the attributive character of each instant message at least may include temporal characteristics and ranking feature etc., versionThis number method of salary distribution is also possible to different, is just not especially limited herein, as long as the version number can be identified for that out that some disappearsBreath, and can be according to the attributive character for needing to identify the message of current environment.
In embodiments of the present invention, it is contemplated that some special situations are illustrated for software is broadcast live, if certain is for the momentIt carves, there is a large amount of user to log in the live streaming software, and send instant message in corresponding direct broadcasting room, if these instant messagesIt is stored in local, the operation of long connection server may be influenced, it therefore, in embodiments of the present invention, can also be using such asThe modes such as cloud storage store above-mentioned instant message.
Further, after long connection server receives the instant message from transmitting terminal, to the reception of the instant messageBroadcast notice messages are held, to prompt receiving end to there is not received message.
Specifically, long connection server can disappear immediately after receiving the instant message from transmitting terminal according to thisBreath generates corresponding notification message, and the notification message is broadcast to receiving end, so that receiving end be prompted to connect server longThere is not received message in end.
In embodiments of the present invention, long connection server is not to be pushed to the message when receiving instant messageReceiving end, but receiving end is broadcast in the form that message is broadcasted.Assuming that a certain moment, long connection server receives 5 i.e.When message, correspond to and the notification message of at least one byte can be generated, for example, " you have 5 unread messages " or " you have notThe form notification message in this way such as reading message ".The notification message can be sent to receiving end by long connection server, receiving end according toThe notification message, which determines, has not received message.
It can be seen from the above, long connection server prompts receiving end presence not received by way of broadcast notice messagesMessage can make receiving end timely learning have unread message, and then can selectively check above-mentioned instant message.
Further, whether the receiving end that long connection server can detecte instant message is online, if online, then to instantThe receiving end broadcast notice messages of message.
Specifically, in the instant message that above-mentioned long connection server can be sent according to transmitting terminal, it is directly wide to receiving endBroadcast notification message；Can also be whether online to receiving end before the broadcast notice messages of receiving end, is first detected, according to the knot of detectionFruit determines whether receiving end broadcast notice messages.Because receiving end is likely to occur offline, or is dodged due to networkPhenomena such as disconnected, so long connection server can first detect whether receiving end is online, and according to detection as a result, when receiving end existsBroadcast them notification message when line.Continue to watch certain match for example, a certain user logs in certain live streaming software again after 30 minutesThing live streaming, when the user just logins successfully, long connection server can broadcast notice letter to equipment used in the userBreath, to notify there is unread message in offline 30 minutes of the user.The application does not limit the message content of broadcast noticeIt is fixed, it for example, how many unread message in 30 minutes can be notified, can also notify how many unread message shared, can also notifyPeople of unread information in 10 minutes, or only notice has people of unread information etc..
In embodiments of the present invention, above-mentioned long connection server is not to fix to receiving end broadcast notice messages time point's.In the actual process, suitable time point sending out notice message can be selected according to the actual situation, for example, can connect longIt connects server and detects that receiving end is in online, but for a long time in when being not logged in state, from long connection server to connecingReceiving end pushes above-mentioned notification message.Alternatively, server can also be connected by long when receiving end has just logged in long connection serverAbove-mentioned notification message is pushed to receiving end.
Step 102, the message acquisition request from receiving end, the maximum comprising local message received in the request are receivedMessage version number.
In this step, server is connected for long, long connection server can receive the acquisition of the message from receiving endRequest, wherein the maximum message version number of receiving end message received is included at least in the message acquisition request.
Specifically, the transmission interaction of information is realized by communication connection in long connection server and receiving end, when receiving end toWhen long connection server sends message acquisition request, long connection server will receive the message acquisition request.Wherein, at thisThe maximum message version number of receiving end received message is included at least in message acquisition request.
In embodiments of the present invention, the message that receiving end is received is the message pushed from long connection server, becauseThis, what above-mentioned maximum message version number indicated is receiving end before sending message acquisition request, and receiving end institute is received lastThe version number of one message corresponding distribution in above-mentioned steps 101.It should be noted that above-mentioned maximum message version number may be used alsoTo be the corresponding version number of particular message at preset time point.For example, certain user logs in certain live streaming software, the live streaming for the first timeThere is no the records that it receives instant message in the corresponding long connection server of software, at this point it is possible to choose preset time pointThe version number for locating particular message, as maximum message version number, it is assumed that current time 11:00, which logs in for the first time shouldThe a certain direct broadcasting room of software is broadcast live, at this point it is possible to when by 10:00, corresponding to first instant message occurring in the direct broadcasting roomVersion number as maximum message version number.
It can be seen from the above, in above-mentioned steps 101, it is long between long connection server and transmitting terminal and in step 102It is all to carry out information transmission by communication connection to interact between connection server and receiving end.And the specific connection of communication connectionWhat mode can be determined according to existing communication protocol, for example, can be according to Transmission Control Protocol (Transmission ControlProtocol, transmission control protocol), long connection server is established with transmitting terminal and receiving end respectively in a manner of TCP connection and is led toNews connection.In addition, in embodiments of the present invention, above-mentioned transmitting terminal and receiving end belong to client, and the equipment of client both may be usedCan also be used as receiving end as transmitting terminal.For example, certain user watches certain live streaming using computer, which both can be used as hairSending end sends instant message for the user, can also be used as receiving end and receives the instant message that other users send.
Step 103, it after long connection server receives message acquisition request, collects and is greater than from stored instant messageCollected message is pushed to receiving end by the message of maximum message version number.
In this step, long connection server is after the message acquisition request for receiving receiving end transmission, according to the messageThe maximum message version number for the receiving end message received for including in acquisition request, in long connection server local, rootIt according to the version number distributed in step 101, collects version number and is greater than message corresponding to above-mentioned maximum message version number, and will be receivedThe message collected is pushed to receiving end.
Specifically, be illustrated by taking the version number 10H30M1 in above-mentioned steps 101 as an example, in long connection server 11:When 00, the message acquisition request of the receiving end transmission received, it is assumed that the maximum message version for including in the message acquisition requestIt number is 10H30M1, at this point, long connection server is according to the corresponding version number of the instant message stored in local, it is confirmableIt is the last item message that receiving end is received when sending message acquisition request be version number is to disappear corresponding to 10H30M1Breath, therefore, long connection server may collect in after this message of 10H30M1 occurs to current time 11:00, this periodAll instant messages of interior appearance, and these message are pushed to receiving end.
In embodiments of the present invention, above-mentioned message push refers to that long connection server is greater than maximum message for what is be collected intoAfter the message of version number summarizes the corresponding unread message list of generation, it is sent to receiving end in batches according to unread message list.
Further, after collected message is pushed to receiving end by long connection server, long connection serverReceive the reception success receipt from receiving end.
Specifically, receiving end can incite somebody to action after growing connection server and the above-mentioned message being collected into is pushed to receiving endMessaging list has been read in the message generation that user has read in PUSH message, is sent to long connection server expression and is received successfully, is convenient forTracking of the long connection server to message traces.
In embodiments of the present invention, when above-mentioned long connection server server corresponding for live streaming software, length connectionServer can correspond to multiple direct broadcasting rooms, each direct broadcasting room has its corresponding direct broadcasting room mark.
Further, when receiving end constantly switches direct broadcasting room, above-mentioned disappear is collected the embodiment of the invention also provides a kind ofThe method of breath, as shown in Fig. 2, may comprise steps of:
Step 201, direct broadcasting room mark where long connection server identification receiving end.
Specifically, long connection server can pass through the live streaming where identification receiving end when receiving end switches direct broadcasting roomBetween, determine the corresponding direct broadcasting room mark of the direct broadcasting room.
Step 202, the corresponding stored instant message of inquiry direct broadcasting room mark.
Specifically, inquiring for the direct broadcasting room in step 201 and connecting server sheet long corresponding to direct broadcasting room markStored instant message in ground.
Step 203, summarize the message greater than the maximum message version number.
Specifically, inquiring obtained instant message according to step 202, summarize disappear corresponding greater than maximum message version numberBreath, as the message pushed to receiving end.
It can be seen from the above, technical solution provided in an embodiment of the present invention, can at least be used in following two scene, toolBody is as follows:
Scene one, when receiving end long time treatment off-line state, or when there is flash due to network etc.,Receiving end is asked by the message acquisition request to long connection server transmission, long connection server according to the message acquisition receivedIt asks, is collected from the instant message being locally stored and be greater than message corresponding to above-mentioned maximum message version number, and the message is pushed awayReceiving end is given, the message that transmitting terminal is sent when receiving end being allowed to obtain offline effectively avoids the loss of message.
Scene two, when receiving end constantly switches direct broadcasting room, long connection server is according to direct broadcasting room where current receiving endCorresponding stored instant message, collects and is greater than message corresponding to above-mentioned maximum message version number, and the message is pushedTo receiving end, avoids receiving end when being switched to new direct broadcasting room, occur the phenomenon that awkward silence at a meeting due to information drop-out.
In conclusion using technical solution provided in an embodiment of the present invention, it is possible to prevente effectively from offline, sudden strain of a muscle occurs in receiving endWhen disconnected or switching direct broadcasting room, the phenomenon that server message goes out active.
