急问：客户端http程序怎么把数据以post的方式传给服务器端的asp文件？

[sxsy]

譬如说，我要把command＝getparam以post方式提交，
是不是直接使用CHttpFile::AddRequestHeaders添加呢？

我试了几次，CHttpFile::AddRequestHeaders返回都是0，即函数调用失败，这又是为什么？
是不是和CHttpConnection::OpenRequest有关系？

多谢各位了！

void post()
{
CInternetSession session("My Session");
CHttpConnection* pServer = NULL;
CHttpFile* pFile = NULL;
CString ServerName = "webmail.21cn.com";
INTERNET_PORT nPort = 80;
DWORD retcode;
char outBuff[300] = "LoginName=avalidloginname&passwd=avalidloginpwd&DomainName=21cn.com";//I have test this with my loginname and password
try
{
pServer = session.GetHttpConnection(ServerName,nPort);
pFile = pServer->OpenRequest(CHttpConnection::HTTP_VERB_POST,"/NULL/NULL/NULL/NULL/NULL/SignIn.gen",NULL,1,NULL,NULL,INTERNET_FLAG_EXISTING_CONNECT);
pFile -> AddRequestHeaders("Content-Type: application/x-www-form-urlencoded");
pFile -> AddRequestHeaders("Accept: */*");
pFile -> SendRequest(NULL,0,outBuff,strlen(outBuff)+1);
pFile -> QueryInfoStatusCode(retcode);
// you can read from the file after this......I've just left it out.
for(int i=0;i<10;i++)//read ten line of returned HTML,you need to edit this to use the result
{
CString smsg;
pFile->ReadString(smsg);
AfxMessageBox(smsg);
}
}
catch (CInternetException * e){};
delete pFile;
delete pServer;
session.Close();
}

谢谢，刚刚搞定（调用SendRequest错误）。正准备来删帖子的，不想已经有人回了，仍很感谢。
