3.         CString strCookieData="name+xxxxxxxxxxxx";
4.         char PacketBuff[1024];
5.         char szBuff[1024]={0};
6.         DWORD dwRet;
7.         strcpy(GETaddr,"/sample/list.php");
8.         if(!pSession->SetOption(INTERNET_OPTION_SEND_TIMEOUT,3600*1000/2) /
9.             ||!pSession->SetOption(INTERNET_OPTION_RECEIVE_TIMEOUT,3600*1000/2))//30min 
10.         {

2.POST方法：（可以post文件）

1. try
2. {
3.     //接收所有文件類型
4.     char accept[] = "*/*";
5.     //參數需要的數組
6.     const char *acArray[2] = {accept,NULL};
7.     LPCTSTR* ppstrAcceptTypes = acArray;
8.     pFile = pServer->OpenRequest("POST", "/sample/submit_sample.php",NULL,1,ppstrAcceptTypes,
9.         NULL,INTERNET_FLAG_EXISTING_CONNECT);
10.     pFile->AddRequestHeaders(strHeaders,HTTP_ADDREQ_FLAG_ADD);
11.     
12.     if(!pFile->SendRequestEx(size))
13.     {
14.         MessageBox(NULL,"SendRequest False!","Post",MB_OK);
15.         return;
16.     }
17.     //  pFile->WriteString((char *)databuff);  
18.     pFile->Write(databuff,size);    
19.     pFile->EndRequest();
20.     
21.     pFile->QueryInfoStatusCode(dwRet);
22.     if (dwRet == HTTP_STATUS_OK)
23.     {
24.         while(UINT nRead=pFile->Read(PacketBuff, 1024-1))
25.                 strncat(szBuff,PacketBuff,nRead);
26.     }
27.     else
28.     {
29.         MessageBox(NULL,"HTTP_STATUS_ERR","HTTP連接錯誤!",MB_ICONERROR);
30.         delete [] databuff;
