如果是带验证码的网页登录比较麻烦，如果不带验证码的比较好办一些，你查看网页源代码，找到form表单中各个表单项后，将各表单项组合成字符串如：username=abc&password=123456，最后再用Post方式将这个字符串作为参数提交到服务器上即可。但是注意有的网站在提交时需要将post参数URLEncode，在服务器反馈后可以自己分析信息头，也可以用pFile->QueryInfo(HTTP_QUERY_SET_COOKIE,cookie);得到各个cookie值。

比如说:126邮箱怎么进去呢？

pFile->AddRequest里都要加什么啊

126邮箱,带账号密码的...用上面的方法改了改,不行.
谁位帮我看看,void CPost2Dlg::OnOK()
{
// TODO: Add extra validation here
CString strObject;
INTERNET_PORT nPort;
CString strFormData;
DWORD dwServiceType;
CInternetSession g_Session_HG("My Session");
CString strContent="";
CHttpConnection* pServer = NULL;
CHttpFile* pFile = NULL;

CString strURL="http://www.126.com";
CString strRetMsg;
strFormData="user=yindoor000&password=6675027&style=-1&remUser=checked&secure=checked";

if(!AfxParseURL(strURL,dwServiceType,strServer,strObject,nPort)||
dwServiceType != INTERNET_SERVICE_HTTP)
{
return ;
}
pServer = g_Session_HG.GetHttpConnection(strURL,nPort);

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

pFile->AddRequestHeaders("Content-Type:text/html; charset=gb2312");

BOOL result = pFile->SendRequest(NULL,0,
(LPVOID)(LPCTSTR)strFormData, strFormData.GetLength());
DWORD dwRet;
pFile->QueryInfoStatusCode(dwRet);

if (dwRet != HTTP_STATUS_OK)
{

return ;
}

CString cookie;
pFile->QueryInfo(HTTP_QUERY_SET_COOKIE,cookie);
if( cookie!="" )
g_Session_HG.SetCookie(strURL,"",cookie);
CDialog::OnOK();
CString str=""
CString a="";
while(pFile->ReadString(a))
{
str+=a;
str+="\r\n";
}
SetDlgItemText(IDC_EDIT1,str);
}

pServer = g_Session_HG.GetHttpConnection(strServer,nPort); pFile->SendRequest之间没有取返回值吗?如何获得请指教@!

......这么没人气啊..楼主再加二百分吧.谁能解释下strObject的意思?

好,现在知道strObject是form里的action了.但是我把126上的"http://entry.126.com/cgi/login" 加上,结果却是"找不到指定的文件" 如何解决呢?

给你一段代码
m_strSendData.Format("/imageservice/GetBillImage?USERNAME=%s&PASSWORD=%s&BILLNO=%s&BILLTYPE=%d&ISSUB=%d\r\n",m_strUserName,m_strPassword,m_strBillNO,m_nBillType,m_cbSub.GetCurSel());
// m_strSendData.Format("/imageservice/GetBillImage");
CInternetSession session("ImageSession");
CHttpConnection* pServer = NULL;
CHttpFile* pFile = NULL;
char szBuff[1024];
try
{
static TCHAR hdrs[] = _T("Accept: */*\r\nUser-Agent: Java1.3.1_01\r\nContent-Type: application/x-www-form-urlencoded\r\n");
static TCHAR accept[] = _T("Accept: */*\r\n"); CString strServerName;
CString strHtml="";
INTERNET_PORT nPort;
DWORD dwRet;
// strServerName = "http://" + m_strServerIP;
nPort = m_nPort;
pServer = session.GetHttpConnection(strServerName,0,nPort);
pFile = pServer->OpenRequest(CHttpConnection::HTTP_VERB_POST,m_strSendData,NULL,1,NULL,"HTTP/1.1");
pFile->AddRequestHeaders(hdrs);
pFile->SendRequestEx(m_strSendData.GetLength());
pFile->WriteString(m_strSendData);
pFile->EndRequest(); pFile->QueryInfoStatusCode(dwRet);

if (dwRet == HTTP_STATUS_OK)
{
CString strLine;
while ((pFile->ReadString(strLine))>0)
{
strHtml += strLine;
} }
delete pFile;
delete pServer;
CFile cfImage;
cfImage.Open("c:\\imageinfo.txt",CFile::modeCreate|CFile::modeReadWrite);
cfImage.Write(strHtml,strHtml.GetLength());
cfImage.Close();
}
catch (CInternetException* pEx)
{
//catch errors from WinInet
}
session.Close();

主要是HTTP报头和读出的问题

第一次取得COOKIE,第二次就不能取到COOKIE　什么原因？

只说了一个小问题，事实上，要了解的书包括：http协议（尤其是http头的内容），然后根据协议处理得到的数据javascript cookie产生的机制现在趋于复杂化，往往在javascript中产生关键的cookie

下面的代码我一直在用
至于COOKIE ,有个更简单的办法可以直接去COOKIE的目录进行读取您需要的话,可以给您写SAMPLE CODEVARIANT id, index;
CComPtr<IDispatch> spDispatch;
CComQIPtr<IHTMLDocument2, &IID_IHTMLDocument2> pDoc2;
CComPtr<IHTMLElement> pElement;
CComPtr<IHTMLElementCollection> pElementCol;
CComPtr<IHTMLFormElement> pFormElement;
CComPtr<IHTMLInputTextElement> pInputElement;
if (m_pBrowserApp){ if (SUCCEEDED(m_pBrowserApp->get_Document((IDispatch**) &pDoc2)))
if(pDoc2!=NULL)
{
{
if (SUCCEEDED(pDoc2->get_forms(&pElementCol)))
{
// AfxMessageBox("IHTMLElementCollection");
long p=0;
if(SUCCEEDED(pElementCol->get_length(&p)))
if(p!=0)
{
// AfxMessageBox("1");
for(long i=0;i<=(p-1);i++)
{ V_VT(&id) = VT_I4;
V_I4(&id) = i;
V_VT(&index) = VT_I4;
V_I4(&index) = 0; if(SUCCEEDED(pElementCol->item(id,index, &spDispatch)))
{ // AfxMessageBox("2");
pFormElement = NULL;
if(SUCCEEDED(spDispatch->QueryInterface(IID_IHTMLFormElement,(void**)&pFormElement)))
{
// AfxMessageBox("IHTMLFormElement");
long q=0;
if(SUCCEEDED(pFormElement->get_length(&q)))
for(long j=0;j<=(q-1);j++)
{
V_VT(&id) = VT_I4;
V_I4(&id) = j;
V_VT(&index) = VT_I4;
V_I4(&index) = 0;
spDispatch = NULL;
if(SUCCEEDED(pFormElement->item(id,index, &spDispatch)))
{
pInputElement = NULL;
if(SUCCEEDED(spDispatch->QueryInterface(IID_IHTMLInputTextElement,(void**)&pInputElement)))
{
//AfxMessageBox("IHTMLInputTextElement");
CComBSTR value(in_strValue);
CComBSTR type;
CComBSTR name; pInputElement->get_type(&type); CString strtype(type);
strtype.MakeUpper(); if ((strtype == L"TEXT") || (strtype == L"PASSWORD") )
{
pInputElement->get_name(&name);
CString strName(name);
if(strName.Find(in_strEdtName)!=-1)
{
pInputElement->put_value(value);
return true;
}
}
}
}
}
}
}
}
}
} } }
} return false;
}
