In one embodiment, which can be broadcast to the business processing of client by long connection service module In module.

In the embodiment of the present application, based on healthy and strong long connection communication link, mobile client can receive long company at any time The business datum for connecing server push improves the availability of long connection service.

The embodiment of the present application can also carry out mobile client and server by synchronous point information to the business datum Data management by synchronization ensure that the synchronous of the data between server and client.

In view of in mobile terminal network state it is unstable, when long connection server is to user's propelling data, if with The mobile terminal at family is in suspension state, this message will lose.Therefore the arrival rate in order to guarantee propelling data, this Shen Please embodiment provide push and pull two kinds of operating modes, if propelling data fails, user can be under pull mode The long connection server data to be pushed are taken, does so and data arrival rate can be improved.

Pull mode occurs after the long connection of each foundation, and this occasion is special in entire mobile client life cycle It is not more, connection behaviour is established as that can re-execute when app is initially opened the long connection of needs foundation, app does not receive heartbeat response message Make, therefore can still enter pull mode.

Referring to Fig. 3, a kind of step flow chart of communication means embodiment two of the application is shown, the embodiment of the present application can To be applied in mobile client, suitable for the scene of pull mode, it can specifically include following steps:

Step 301, long connection service initialisation is carried out；

In the concrete realization, initial work can be with Exactly-once in the life cycle of entire application program app.

In a kind of preferred embodiment of the embodiment of the present application, initial work can include but is not limited to following one kind Or it combines:

Create the type of Service Processing Module and the mapping relations of call back function；For the type addition of Service Processing Module Corresponding data decryptor；Initialize the information of server and/or the information of the corresponding application program of the mobile client；For Application program switches to the setting of the case where backstage and monitors；It is monitored for application program from setting the case where switching to front end from the background； Or, the monitoring of addition user's logging state.

Specifically, being illustrated below to the case where various initialization:

1) type of Service Processing Module and the mapping relations of call back function are created.

The process for creating the type (type) of Service Processing Module and the mapping relations of call back function is properly termed as service line Initialization a, wherein type represents a Service Processing Module.

For example, if Service Processing Module is message center module, if message center module makes to realize push in real time When with long connection service, can define type is AT_TRIPWMC_NOTIFY, and call back function class is TRIPMsgCenterRPCSyncService realizes call back function processing module in such, when there is new data, long connection Service by socket long connection communication link by newest data-pushing to mobile client, Data will be received in the call back function of TRIPMsgCenterRPCSyncService.

2) corresponding data decryptor is added for the type of Service Processing Module.

After the long connection service module of client obtains data from server by long interface channel, it will be counted to realize According to calling service side is passed to, data decryptor can be added for each type herein, for receiving data, because in 1) It is the binding for realizing type and call back function, thus may be implemented to handle the data received in call back function.

3) information of server and/or the information of the corresponding application program of the mobile client are initialized.

As an example, the information of server can include but is not limited to: server address and port numbers.Using journey The information of sequence can include but is not limited to: Apply Names and application version.

In the embodiment of the present application, setting server address can be used for being arranged with server communication the letter of application program Breath can be used for notifying server with the mobile client of its communication which to be using which version, the purpose for the arrangement is that allowing clothes Business device identifies the identity information of mobile client.

For socket service, it is 443 that its port numbers, which can be set,.

4) the case where switching to backstage for application program setting is monitored.

Monitoring when App cuts backstage is added herein, switches to backstage to detect application program in time.

In the concrete realization, it is monitored due to there is the case where switching to backstage for application program setting, when App is switched to When backstage, can send long connection this long interface channel of server of out code notice first will be closed, to reduce resource Waste, then deletes all data decryptors, prevents system crash crash, this is because after App switches to backstage, the App meeting Fallen by operating system kill, at this time if there are also data decryptor, system is easy crash.

5) it is monitored for application program from setting the case where switching to front end from the background.

Monitoring when addition App arouses to front end herein, is aroused with detecting application program in time to front end.It is implementing In, due to existing for application program from monitoring is arranged the case where switching to front end from the background, when App is aroused again to front end When, long connection communication link can be re-established.

6) monitoring of user's logging state is added.

In the embodiment of the present application, it supports to press User ID PUSH message, therefore, mobile client needs in time step on user Related news whether record are reported to long connection server, add the monitoring of user's logging state thus.

In the concrete realization, since there are the monitorings of user's logging state, when users log on, mobile client can be to The instruction of server end transmission user bound；When user logs off, mobile client can send unbundlings to server-side and refer to It enables, so that server end be allowed to know that the mobile client of this current long connection communication link has logged out login, cannot press again PUSH message is removed according to User ID.

Step 302, the Socket connection between the mobile client and server is created；

In the concrete realization, can call Basic API create Socket, and call Basic API realize data transmission and It receives.

In one embodiment, if the system that mobile client is currently located is iOS system, since iOS system is base In the operating system of FreeBSD (FreeBSD is a type UNIX operating system) exploitation, in FreeBSD operating system, BSD Socket is realized with C language completely, and can be used in Objective-C code, but this primary Socket without Method accesses the included network characteristic (wifi, cellular network) of iOS operating system.If there is no thread accesses bee in iOS system Nest network, it can be automatically closed to save electricity, but primary Socket will not automatically open the wifi of equipment, if long connect The service of connecing is based on primary Socket, with regard to will appear very big problem.

Similar with the Socket socket of Windows system, iOS system provides CFNetwork and carries out Socket communication, CFNetwork is the high performance framework of bottom (framework), and BSD socket is encapsulated and extended, is provided With the function of HTTP/FTP/TCP/DNS server communication, (Cocoa is that Apple Inc. is created by Mac OS X to Cocoa The API of primary object-oriented) in Webkit and NSURL be dependent on CFNetwork.In addition, CFNetwork is integrated with Runloop mechanism, each thread has the run-loop of oneself, therefore the event source in CFNetwork can be added to Processing network event is removed in run-loop, the advantage of doing so is that allow developer without in the case where considering multithreading, it can be with Operate network protocol.Meanwhile CFNetwork is integrated into iOS system, and cellular network can be kept not to be automatically closed, solution Determined BSD Socket the problem of.

In the embodiment of the present application, it can realize that long connection communication for service, CFNetwork are mainly wrapped based on CFNetwork API: the first module for including two modules is CFSocket, and major function is the TCP link of building client and server, and And it is integrated into run-loop；Second module is CFStream, provides a kind of and device-independent data exchange Side is below introduced creation Socket and the Key Functions being written and read.

1, Basic API is called to create Socket

The first, socket is created

In the concrete realization, CFNetwork provides an easily creation function CFStreamCreatePairWithSocketToHost, can be a pair of for given host name and port creation Socket, one is used to read, and one for writing.Call API as follows: CFStreamCreatePairWithSocketToHost(kCFAllocatorDefault,(__bridge CFStringRef) [url host],[[url port]integerValue],&readStream,&writeStream)；

Wherein, url represents the address of long connection server, and CFNetwork frame is responsible for host name being converted to IP address, Port numbers are converted into network bytes sequence, readStream represents the byte stream for reading data, and writeStream is represented For writing the byte stream of data.

The second, data flow binds call back function

Data flow is bound into a call back function readSocketCallback, corresponding number can be handled in this function According to API is as follows:

CFStreamClientContext ctx={ 0, (_ _ bridge void*) (self), NULL, NULL, NULL }；

CFOptionFlags registeredEvent=(kCFStreamEventHasBytesAvailable | kCFStreamEventEndEncountered|kCFStreamEventErrorOccurred| kCFStreamEventOpenCompleted)；

CFReadStreamSetClient(readStream,registeredEvents, readSocketCallback,&ctx))；

Wherein, CFReadStreamSetClient indicates the bindings of reading data flow readStream, first ginseng Number represents the stream of generation event, and all each functions for processing stream have the application for being directed toward it；Second parameter generation Table wants the stream event received, and kCFStreamEventHasBytesAvailable representative has the data that can be read, KCFStreamEventErrorOccurred represents operation and mistake occurs, and kCFStreamEventEndEncountered is represented The end of byte stream is reached, kCFStreamEventOpenCompleted indicates that Socket is successfully opened；Third parameter is The call back function of binding, is passed into as event；4th parameter is represented as stream assembly CFStreamClientContext structural body is directed toward oneself info object and call back function come the context pointers created, leads to It can be often a self reference.

For writing data flow writeStream, CFNetwork provides following API:

CFWriteStreamSetClient(writeStream,registeredEvents, writeSocketCallback,& ctx))；

Its parameter definition is similar with CFReadStreamSetClient.

Runloop (incident management object) is added in third, data flow

By data flow be added runloop after, client just can in next runloop distribution processor data flow, API is such as Shown in lower:

CFReadStreamScheduleWithRunLoop(readStream,CFRunLoopGetCurrent(), kCFRunLoopCommonModes)；

CFWriteStreamScheduleWithRunLoop(writeStream,CFRunLoopGetCurrent(), kCFRunLoopCommonModes)；

Wherein, CFRunLoopGetCurrent () returns to current thread default operation circulation, and runloop operational mode is kCFRunLoopCommonModes。

4th, flow data is opened

It needs that CFReadStreamOpen is called to open reading flow before using flow data, calls CFWriteStreamOpen opening writes data flow.

5th, start runloop

It calls CFRunLoopRun (), starts runloop, because being added to read-write data flow in thirdly In runloop, need to do start-up operation in this step.

2, Basic API is called to realize sending and receiving for data

In above-mentioned second point, time data stream readStream is tied up with call back function readSocketCallback It is fixed, write data flow writeStream and call back function writeSocketCallback and bound, it is long connect be successfully established with Afterwards, client will receive data and realize in function readSocketCallback, and wanting to send data to server end need to be It is realized in function writeSocketCallback.

ReadSocketCallback function is as follows:

readSocketCallback(CFReadStreamRef stream,CFStreamEventType event, void*myPtr)；

Wherein, parameter stream represents the character stream received, and parameter event represents received stream event, myPtr representative office The object of character stream is managed, myPtr parameter is passed to when calling CFReadStreamSetClient in above-mentioned second point, according to not Same event type has different processing clients.

Specifically, event value is that kCFStreamEventOpenCompleted indicates that long communication channel connects and is successfully established； Event value is that kCFStreamEventHasBytesAvailable expression has the data that can be read at present, connects lower utilization and follows The data of stream are all read local character string by constantly cumulative by ring；Event value is KCFStreamEventEndEncountered is indicated to have read the end of byte stream, is needed to notify upper layer module this time Data are successfully received, and CFReadStreamClose is called to close stream, are called CFReadStreamUnscheduleFromRunLoop takes down stream from runloop.Event value is KCFStreamEventErrorOccurred indicates socket operation failure.The processing client of writeSocketCallback End is similar with readSocketCallback, and details are not described herein.

Step 303, judge whether the Socket connection is successfully established；If so, 304 are thened follow the steps, if it is not, then executing Step 305；

In a kind of preferred embodiment of the embodiment of the present application, step 303 be can further include: read what connection was established Return value；According to the return value, judge whether the Socket connection is successfully established.

Specifically, can judge whether Socket connection is successfully established by the return value that connection is established, for example, if returning Returning value is kCFStreamEventOpenCompleted, then can be determined that bottom Socket long connection creates successfully；If return value For kCFStreamEventErrorOccurred, then it can be determined that bottom Socket long connection creation failure.

Step 304, the long connection communication link between the mobile client and server is established；

When determining that Socket connection is successfully established, mobile client and server can be by<ports IP+>in network The TCP layer of agreement establishes long connection communication link, next can carry out data communication on this link.

Step 305, it executes and retries operation.

In the embodiment of the present application, when determining that Socket connection establishes unsuccessful, it can execute and retry operation.

In a kind of preferred embodiment of the embodiment of the present application, step 305 may include following sub-step: will retry in real time Connection number subtracts one, wherein the initial value for retrying connection number in real time is that preset maximum retries connection number；If the real-time weight Try connection number and be greater than default connection number thresholding, it is determined that delay duration, and according to delay duration delay after, continue to execute institute State step 302；If the connection number that retries in real time is less than or equal to default connection number thresholding, current long connection service is determined not It can use.

In the concrete realization, mobile terminal is to be connected by wireless signal with base station, and base station forwards the information to long connection Server, when meeting the barriers such as high building or switching base station, long connection is easy to break, meanwhile, for long connection service For device, each long connection can occupy a port, and communication failure is also easy when loading excessive, in order to avoid leading to because of network Letter or server health are bad and cause long connection service unavailable, and retry mechanism can be set in the embodiment of the present application, and sets Maximum retries connection number.

Maximum, which retries connection number, indicates the number that can at most retry, for example, it is 15 that maximum, which can be set, to retry connection number.

When determining that Socket connection establishes unsuccessful, start to retry, real-time will retry connection number (when retrying for the first time, Retrying connection number in real time is that maximum retries connection number, i.e., the initial value for retrying connection number in real time is that preset maximum retries connection Number) subtract one, expression, which has wasted, once retries chance, judges to retry whether connection number is greater than default connection in real time after subtracting one Number thresholding (for example, numerical value 0), if it is not, indicating that number of retries has reached upper limit value, this vice-minister connection service is unavailable, if so, really Determine delay duration, and according to delay duration delay after, return to step 302, re-establish socket connection.

In the concrete realization, incremental state can be presented in the delay duration retried each time, such as delay 2S for the first time Execution retries, and second of delay 3S execution retries, etc..

The reason of being delayed herein is: building the major reason successively lost and lost is exactly that server overload is excessively high, this time-frequency Numerous request cannot not only respond, and can aggravate server burden instead, and the success of server response can be improved in delay operation Rate.

Step 306, mobile client passes through the long connection server sending device information of the long connection communication chain road direction；

In the embodiment of the present application, mobile client can send the facility information of local device to long connection server, Connection server long so just knows what concrete property is the equipment for establishing connection with it have.

In one embodiment, the such data of identification device information can be active message.

As the equipment letter that in a kind of preferable example of the embodiment of the present application, mobile client is sent to long connection server Breath can include but is not limited to: operating system, operating system version, app title where mobile client, are set app version number Standby mark, protocol version and network state etc..

For example, the example of a kind of pair of facility information is as follows:

{"osType":"iOS","osversion":"10.2","appName":"ALITRIP","appVer":" 8.1.2",

"dId":"ArweOM01VHF4J79C4etS21nSe0SN9M9IEmlP5gdANG1","network":" wifi","linkExtInfo":"ee3633ab346b358cb1da2bd3f1bd6912","linkVersion":" 2.0.0 ", " action ": " active " },

In order to distinguish different data types, above-mentioned action can be set to active, bottom can do data Compression and encryption.

Step 307, judge whether receive in first time period, the long connection server is based on the facility information The equipment response message of return；If so, thening follow the steps 308 and step 309；If it is not, thening follow the steps 305；In the application reality It applies in example, after sending active data to long connection server, the active data creation active order can be directed to Timer, whether long connection server end has return after which can be used for monitoring sending device information Value, which is equipment response message, wherein equipment response message can serve to indicate that the corresponding business of the facility information Server is in active state.

Specifically, the purpose of active order timer is to guarantee have corresponding service server to handle long link information, The socket long connection of foundation is based on mobile client and long connection server, if not as corresponding service server The service is still unavailable.For this purpose, mobile client connects server uploading device information to long, at the same create timer do it is super When handle, for example, 10S can be set by the timing of active order timer.

If not receiving the return value of long connection server in the timing length of active order timer, illustrate to grow Connection is broken, can execute step 305 at this time.

It should be noted that active order timer only needs to be implemented once in the embodiment of the present application, without repeating Execute, this is because waste a large amount of cpu resources if endless loop will be entered by repeating, build successively lose lose after retry it is primary such as Fruit still fails, and illustrates that long connection server does not have corresponding service server, services unavailable.

If receiving the return value of long connection server in the timing length of active order timer, illustrate following two Point: one, local App and long connection server have created Socket long connection；The second, at the corresponding service server of the App In active state, and service server has been obtained for the facility information of equipment.

When the return value for receiving long connection server in the timing length of active order timer, active can be ordered Enable timer be set to nil (nil is an object value, uses nil if when an object is set as sky).

In the concrete realization, mobile client can be in call back function readSocketCallback Equipment response letter is determined in (CFReadStreamRef stream, CFStreamEventType event, void*myPtr) Breath, event value are that kCFStreamEventEndEncountered expression completely receives an information, first pass through decompression, Then data parse, and distinguish protocol header and message body, last mobile client obtains following returned data:

{"action":"active","connnectCode":

" WIHJc2BxYcDAHTxtEbqYAK ", " keepLiveTime ": " 240 " },

Wherein action field indicates type of message, and connnectCode is generated by long connection server end, for marking Know unique field of equipment and long connection, long connection and facility information can be established mapping table, subsequent shifting by long connection server end The message that dynamic client is sent needs to carry this value, facilitates the identity of long connection server identification client, KeepLiveTime represents heart beat cycle.

In the embodiment of the present application, mobile client can also obtain user's logging state information, and the user is logged in Status information is sent to long connection server, to be bound or be unbinded operation.

Specifically, bind order can be sent to long connection server if mobile client is in logging state, for example, Specific instructions are as follows:

{"connnectCode":"WIHJc2BxYcDAHTxtEbqYAK","action":"bind"," SessionId ": " 3c008beb359660009e459c7bbaf6a721 " },

Wherein, connnectCode is for identifying unique field of equipment and long connection in return value, and action value is Bind, for distinguishing different upstream messages, sessionId is used for identity user userId, when long connection server receives this The corresponding user information of equipment is known that after item order, connection server long in this way can push different for different users Content.

Further, since the monitoring of User Status is added to, when User Status is by being not logged in long connection service initialisation Long connection server will be notified when becoming logging state, bind order be sent, when User Status becomes not step on by having logged in When record, unbind unbundling commands are sent, notify long connection server equipment is in be not logged in state, for pushing by userId Content cannot issue this equipment.

For example, the format of unbind order are as follows:

{"connnectCode":"WIHJc2BxYcDAHTxtEbqYAK","action":"unbind",

" sessionId ": " 3c008beb359660009e459c7bbaf6a721 " }, action unbind is used for area Divide different orders.

For bind/unbind message, response can not be received in time-out time with creation state status timer When, such message can be retransmitted, rather than re-creates Socket connection.

In the embodiment of the present application, when listening to mobile client and being switched to backstage, mobile client can Xiang Changlian It connects server and sends the message that action value is close.This kind of message is for notifying long connection server current device to break Fall long connection, long connection server can sufficiently provide the utilization rate of resource this resource allocation to other equipment.

Step 308, it determines heart beat cycle, and sends heartbeat message to long connection server according to the heart beat cycle, when It is not received by what long connection server returned in the second preset time period, for the heartbeat response message of the heartbeat message When, return to step 305；

In the concrete realization, established long connection communication link may be broken at any time, and therefore, the embodiment of the present application can be with Long interface channel is safeguarded using heartbeat packet.

Specifically, heartbeat timer heratTimer can be created, every a heart beat cycle keepLiveTime to length It connects server and sends heartbeat message, it, will if time-out does not receive the response that long connection server is directed to the heartbeat message Step 305 is executed, to re-establish socket connection, the purpose for the arrangement is that being used to guarantee the long connection with long connection server Channel keeps connection.

In the concrete realization, heart beat cycle can be arranged by long connection server, mobile client can be in call back function Heart beat cycle is parsed in middle state value kCFStreamEventEndEncountered.

For example, mobile client state value kCFStreamEventEndEncountered in call back function indicates complete Ground receives an information, first passes through decompression, and then data parse, and distinguishes protocol header and message body, last client obtains Following returned data " action ": " active ", " connnectCode ":

" WIHJc2BxYcDAHTxtEbqYAK ", " keepLiveTime ": " 240 " }, wherein keepLiveTime is represented Heart beat cycle 240S.

In practice, heart beat cycle can be arranged according to network state in long connection server, if equipment is in wifi state, Heart beat cycle can be set longer, for example, can be set to 240S；If equipment is in 4G/3G, period setting can be with short by one A bit, for example, can be set to 180S；If equipment is in weak net state, value can be smaller, for example, can be set to 120S；That is net A possibility that network state is better, and long connection is broken is smaller, and heart beat cycle can be longer, the period about long wave that can more reduce resource Take.

The plan of establishment of this heart beat cycle of the embodiment of the present application both can efficiently utilize cpu system resource, simultaneously With extensive flexibility, because server end can be modified at any time.

In the embodiment of the present application, heartbeat message does not have special service logic, it is merely meant that a kind of message body, in order to subtract The data volume transmitted less can use certain amount of byte representation.

For example, heartbeat message can use 15 byte representations are as follows: 04,030,000 00,000,030 30,303,030 303030.

At the same time it can also create overtime timer heartbeatTimeoutTimer, for after monitoring transmission heartbeat message Second time period in whether receive heartbeat response message.

The second time period of heartbeatTimeoutTimer setting, can be set longer, example under wifi state Such as, be set as 15S, can be set under other states it is shorter, for example, being set as 10S.

If not receiving heartbeat response message in second time period, step 305 can be entered, to re-create Socket link illustrates that the long connection of bottom keeps good, does not need to weigh again if receiving heartbeat response message in second time period New creation allows the timed task to fail at this point it is possible to which heartbeatTimeoutTimer timer is set to nil.

Step 309, data acquisition request is generated, and the data acquisition request is sent to by long connection communication link Long connection server, wherein the data acquisition request includes first synchronous point information, continues to execute step 310；

Every time when mobile client receives the return value of active message, into data pull mode, at this point, mobile visitor Family end can be generated data acquisition request (pull message), and send pull message to long connection server, which can To include first synchronous point information, it is therefore an objective to tell long connection server, the progress of local client message synchronization.

In the embodiment of the present application, which may include multiple business processing requests, wherein each business Processing request is for corresponding to one or more business datums.That is, the data acquisition request can be for for different business Business processing request merge after obtained message, to reduce request number of times.For example, pull message can indicate Are as follows:

{"action":"pull","sData":[{"type":"AT_PUSH_RC","sKey":0},{"type":"AT_ H5_PUSH","sKey":170150112736000001},{"type":"AT_TRAIN_TK","sKey":0},{"type":" AT_DIS_MSG","sKey":0},{"type":"AT_CONTROL_PUSH_DEVICE","sKey":0},{"type":"AT_ CONTROL_COMMAND_PUSH_DEVICE ", " sKey ": 0 }] }, wherein action is pull, for distinguishing different uplinks Data, sData are the array array comprising the request of multiple business processings, and each business processing request includes corresponding industry Be engaged in line type and synchronous point skey, and such as the AT_H5_PUSH of type type, last time is synchronized to 170150112736000001, service Next data that device returns are counted since last synchronous point, to realize the data transmission of zero defect.

The synchronous point information of the embodiment of the present application can be generated by the sequence number generator of long connection server end, and with Business datum is sent to mobile client, and a Service Processing Module is provided with a synchronous point information.

Step 310, long connection server is received by long connection communication link acquisition request returns based on the data, The business datum of update, the business datum of the update include the synchronous point information updated, continue to execute step 311；

Specifically, mobile client carries each Service Processing Module to the data acquisition request that long connection server is sent First synchronous point information, the first synchronous point information from local data base obtain.

Long connection server end can be by service identification and synchronous point message reference data center, because protecting in data center The data for having stayed the service line to be pushed may determine that corresponding Service Processing Module synchronized according to the first synchronous point information Progress obtains service line data to be pushed (business datum updated), then by the data to be pushed and newest Synchronous point information is pushed to the long connection service module of mobile client by long interface channel.

Step 311, the business datum of the update and the synchronous point letter of corresponding update are stored in the local database Breath, continues to execute step 312；

For the synchronous point information that long connection server-side issues, mobile client needs to carry out serializing processing, in time will The business datum of update and the synchronous point information preservation of corresponding update in the local database, so that it is guaranteed that data increment, Order transfer.

Step 312, the business datum based on the update generates notification information；The notification information is broadcasted to one or In multiple Service Processing Modules, step 313 is continued to execute；

After serializing work, the long connection service module of mobile client can be generated according to the business datum of the update Notification information, and notification information is notified to by way of broadcast the Service Processing Module of mobile client.

Step 313, the data response message that returns based on the notification information of Service Processing Module is received, and by the number Long connection server is sent to according to response message.

After Service Processing Module receives data, a successful data reception can be sent to long connection service module Data response message, this data response message finally reach long connection server by bottom socket connection.

In the embodiment of the present application, which may include the information and synchronous point letter of Service Processing Module Breath, for informing long connection server, client has had received all data of synchronous point position, and long connection server can be with Notification data center carries out the update update operation of data, for example, carrying out the cleaning operation of some data.
