MFC之HTTP POST请求 （VS2013环境 多字符编码）

1、函数调用

CString URL ="http://ip:8080/XXXX/Register";

CString para = "username=&password=123456";

CString result;

PostContent(URL, para, result);

2、头文件（调用函数实现）post.h

#include "afxinet.h"

#include <string>

bool PostContent(CString strUrl, const CString&strPara, CString &strContent)

{

       try{

              boolbRet = false;

              CStringstrServer, strObject, strHeader, strRet;

              unsignedshort nPort;

              DWORDdwServiceType;

              if(!AfxParseURL(strUrl, dwServiceType, strServer, strObject, nPort))

              {

                     returnfalse;

              }

              CInternetSessionsess;//Create session

              CHttpFile*pFile;

              CHttpConnection*pServer = sess.GetHttpConnection(strServer, nPort);

              if(pServer == NULL)

              {

                     returnfalse;

              }

              pFile= pServer->OpenRequest(CHttpConnection::HTTP_VERB_POST, strObject, NULL, 1, NULL,NULL, INTERNET_FLAG_EXISTING_CONNECT);

              if(pFile == NULL)

              {

                     returnfalse;

              }

              CStringstrHeaders = "Content-Type:application/x-www-form-urlencoded;";

              pFile->SendRequest(strHeaders,(LPTSTR)(LPCTSTR)strPara, strPara.GetLength());

              AfxMessageBox((LPTSTR)(LPCTSTR)strPara)

              CStringstrSentence;

              DWORDdwStatus;

              DWORDdwBuffLen = sizeof(dwStatus);

              BOOLbSuccess = pFile->QueryInfo(

                     HTTP_QUERY_STATUS_CODE| HTTP_QUERY_FLAG_NUMBER,

                     &dwStatus,&dwBuffLen);

              if(bSuccess && dwStatus >= 200 && dwStatus<300)

              {

                     charbuffer[256];

                     memset(buffer,0, 256);

                     intnReadCount = 0;

                     while((nReadCount = pFile->Read(buffer, 2048)) > 0)

                     {

                            strContent+= buffer;

                            memset(buffer,0, 256);

                     }

                     bRet= true;

              }

              else

              {

                     bRet= false;

              }

              pFile->Close();

              sess.Close();

              returnbRet;

       }

       catch(...)

       {

              intnCode = GetLastError();

              returnfalse;

       }

}
