Description
Technical field
The present invention relates to the Internet, applications field, more particularly to a kind of method of client and server bidirectional data transfers.
Background technology
At present, common client and server data interaction has various solutions, such as the HTTP data based on WEB are passed
Give, Socket, database poll, third party's integral data reception processing component etc..Wherein, the client based on HTTP and clothes
The shortcoming of business device end data interaction, including transmission byte number is more, stateless, speed is slow, efficiency is low, it is necessary to largely set up WEB
Main frame, the effect directly brought is high cost, and the inherent stateless of WEB allows the exploitation to become very complicated.Third party is whole
Closing data handling component has not maintainable, bad fault-tolerant, it is difficult to extend, and develops dumb, the shortcomings of copyright is restricted.
Overcome these shortcomings, support the client of all basic Socket exploitations, with long-time line mechanism, design efficiently,
Flexibly, reliability, the client-server end data interactive mode of high-throughput, can be handed over for Set Top Box with AirServer data
Mutually provide and fully ensure, this is the trend of the art development.
The content of the invention
It is an object of the invention to overcome the deficiencies in the prior art part, there is provided a kind of client and server bidirectional data transfers
Method, support the client of all basic Socket exploitations, with long-time line mechanism, realize efficiently, flexibly, it is reliable,
The bi-directional data transmission of high-throughput, is that Set Top Box interacts offer fully guarantee with AirServer data,
In order to achieve the above object, the step of method of the client and server bidirectional data transfers that the present invention is provided is performed is wrapped
Include：
1) AirServer server ends and Socket clients are respectively started；
2) IP at server end and port parameter, binding IP and port numbers are set；
3) client ip and port parameter are set, the server is connected；
4) server end sets up thread, starts Socket and monitors；
5) client and server carries out Socket connections；
6) judge to set up whether connection succeeds, if it is, performing next step；If not, return to step 4)；
7) the client Socket lists are circulated, judges whether to need to transmit data, if it is, performing next step；If not,
Return to step 4)；
8) client will need the content of transmission to switch to byte stream, and data are transmitted to the server end；
9) server end returns or distributes data to the client；
10) server end judges whether the client disconnects, if it is, performing next step；If not, returning
Step 8)；
11) server end removes the client and return to step 1), wait the client to be restored be successfully connected next time after.
The method of client and server bidirectional data transfers of the present invention, wherein described step 8) in, the Socket client
It is TV set-top box to hold, and the content of its transmission at least includes：
(1), the heartbeat data that timing is uploaded for 30 seconds, for recording live box, program request, duration, corrects box service time；

Elaborated below by embodiment.
First, AirServer server ends are started
According to the good IP at server end of software design patterns, port starts Socket and monitors：
1. define a server end and monitor Socket variables
public static Socket listener；Monitor Socket variables
Public List<Socket>OnlineSocket=new List<Socket>()；Preserve client SOCKET lists
2. IP and port parameter are set：
IPAddress ip=IPAddress.Parse (SocketIP)；
IPEndPoint localEndPoint=new IPEndPoint (ip, SocketPort)；
3. binding IP and port numbers
Listener=new Socket (AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp)；
listener.Bind(localEndPoint)；
4. begin listening for
listener.Listen(8000)；
Now server end has been in listening state, is ready to receive client connection.
2nd, client and server is matched
IP is provided according to server end, port numbers carry out Socket pairings：
1. a client Socket variable Socket clientSocket=null is defined；
2. IP and port parameter are set
IPHostEntry hostEntry=Dns.GetHostEntry (server)；
IPEndPoint ipe=new IPEndPoint (IPAddress.Parse (server), port)；
3. connection server SOCKET
ClientSocket=new Socket (ipe.AddressFamily, SocketType.Stream, ProtocolType.Tcp)；
clientSocket.Connect(ipe)；
4. client is preserved in internal memory, for sending data to client
OnlineSocket.Add(clientSocket)；
Being successfully connected rear client can be used clientSocket to be interacted with server end at any time.
3rd, client transmits data and receives return data
Need the content of transmission
String request=" FMath=01 "+Ascii (01)+" CID=XXXXXXXXX "+Ascii (01)
+ " EST=000000000X "+Ascii (01)+" NST=0000000000 "+Ascii (01)+" FMode=0000 "+Ascii (01)
+ " CTime=0000 "；
Switch to byte stream
Byte [] bytesSent=Encoding.UTF8.GetBytes (request)；
If (clientSocket==null) return (" Connection failed ")；
Send data
ClientSocket.Send (bytesSent, bytesSent.Length, 0)；
Receive data
4th, server end transmits data to client
Set up a thread and make broadcast in time for the change of monitored data database data：
Previous step one is stored in client side list in OnlineSocket variables, and newly-built thread can be directed to these clients
Socket is distributed data
Thread taskThread=new Thread (new ThreadStart (ClientHeart))；
taskThread.Start()；
This mission thread can continually scan for database tasks change, and make corresponding distribution in time according to changing content.
Distribute data according to client SOCKET lists have been received：
Above step realizes the transmitted in both directions of data, and server end only needs to a sub- thread poll needs the task of distribution simultaneously wide
Hair data, client does not need continual polling server task, effectively increases operating efficiency.
Function, the performance of the various data below by embodiment to transmitting, input, output are specifically described.
