首先用Httplook 来查看表单提交的内容。
以下函数能够模拟表单提交
bool CCHttpSockDlg::PostContent(CString strUrl, const CString &strPara, CString &strContent, CString &strDescript)
{
try{
strDescript = "提交成功完成!";
bool bRet = false;
CString strServer, strObject, strHeader, strRet;
unsigned short nPort;
DWORD dwServiceType;
if(!AfxParseURL(strUrl, dwServiceType, strServer, strObject, nPort))
{
strDescript = strUrl + "不是有效有网络地址!";
return false;
}
CInternetSession sess;//Create session
CHttpFile* pFile;
//////////////////////////////////////////////
CHttpConnection *pServer = sess.GetHttpConnection(strServer, nPort);
if(pServer == NULL)
{
strDescript = "对不起,连接服务器失败!";
return false;
}
pFile = pServer->OpenRequest(CHttpConnection::HTTP_VERB_POST,strObject,NULL,1,NULL,NULL,INTERNET_FLAG_EXISTING_CONNECT);
if(pFile == NULL)
{
strDescript = "找不到网络地址" + strUrl;
return false;
}
// pFile -> AddRequestHeaders("Content-Type: text/xml; charset=utf-8");
pFile -> AddRequestHeaders("Content-Type: application/x-www-form-urlencoded");
pFile -> AddRequestHeaders("Accept: */*");
pFile -> SendRequest(NULL, 0, (LPTSTR)(LPCTSTR)strPara, strPara.GetLength());
CString strSentence;
DWORD dwStatus;
DWORD dwBuffLen = sizeof(dwStatus);
BOOL bSuccess = pFile->QueryInfo(
HTTP_QUERY_STATUS_CODE|HTTP_QUERY_FLAG_NUMBER,
&dwStatus, &dwBuffLen);
if( bSuccess && dwStatus>= 200 && dwStatus<300)
{
char buffer[2049];
memset(buffer, 0, 2049);
int nReadCount = 0;
while((nReadCount = pFile->Read(buffer, 2048)) > 0)
{
strContent += buffer;
memset(buffer, 0, 2049);
}
bRet = true;
}
else
{
strDescript = "网站服务器错误" + strUrl;
bRet = false;
}
////////////////////////////////////////
pFile->Close();
sess.Close();
return bRet;
}
catch(...)
{
int nCode = GetLastError();
strDescript.Format("向服务器post失败!错误号:%d", nCode);
return false;
}
}
调用方法(这是自动在www.whctwl.com提交留言的方法)
CString strContent,strDescrip;
PostContent(_T("http://www.whctwl.com/message.asp"),_T("Title=asdfasd&OwnerName=werwer&Phone=232323&[email protected]&Homepage=&Content=asdfasdf&Version=cn&IsChecked=False&acction=add&sub=%B7%A2%B1%ED"),strContent,strDescrip);
