Symbian中同步socket用法

 

//下边的代码是介绍同步socket的用法：

//需要用到的lib，可能不全，请看sdk的help自己添加

esock.lib

//需要的头文件，可能不全，请看sdk的help自己添加

#include <in_sock.h>

#include <nifman.h>

#include <Es_sock.h>

 

#if defined __WINS__

_LIT(KConnectIP,"192.168.0.1");//连接的ip地址，换成测试的ip

#else

_LIT(KConnectIP,"10.0.0.172");//移动的cmwap代理网关

#endif

const int KConnectPort = 80;//端口

HBufC8 *SocketGetUrl(TDesC8 &geturl);

void TestSocket()

    _LIT8(KSendData, "POST http:://www.google.com.cn http/1.1\r\n\r\n");

    TBuf8<128> sendData(KSendData);

    HBufC8 *body = SocketGetUrl(sendData);

    if(body)

    {

        //服务器端返回的数据处理

        delete body;

    }

}

                {

                    TInt recvSize = 0;

                   

                    for(;;)

                    {

                        iSocket.RecvOneOrMore(recvBuf, 0, iStatus, iDummyLength);

                        User::WaitForRequest(iStatus);

                       

                        if (iStatus.Int()==KErrNone)

                        {

                            recvSize += recvBuf.Length();

                            if(iBuffer==NULL)

                                iBuffer = HBufC8::NewL(recvSize);

                            else

                                iBuffer = iBuffer->ReAlloc(recvSize);

                            iBuffer->Des().Append(recvBuf);

                        }

                        else

                        {

                            break;

                        }

                    }

                }

            }

            iSocket.Close();

        }

       

        iSocketServ.Close();

    }

    iNif.Close();

    return iBuffer;

}

此段代码只是对socket用法的简单介绍，没有超时处理，如果要做超时处理的话，请自己添加。
