如何使用C++/MFC將POST POST到Web表單？

Question

我在GetHttpConnection中使用CInternetSession，但是我找不到任何關於如何填寫和發佈Web表單的好信息。

Answer 1

This knowledge base article說明如何使用CInternetSession來模擬POST請求。

附帶的範例代碼是這樣的：

CString strHeaders = _T("Content-Type: application/x-www-form-urlencoded"); 
// URL-encoded form variables - 
// name = "John Doe", userid = "hithere", other = "P&Q" 
CString strFormData = _T("name=John+Doe&userid=hithere&other=P%26Q"); 

CInternetSession session; 
CHttpConnection *pConnection = session.GetHttpConnection(_T("ServerNameHere")); 
CHttpFile *pFile = pConnection->OpenRequest(CHttpConnection::HTTP_VERB_POST, 
    _T("FormActionHere")); 
BOOL result = pFile->SendRequest(strHeaders, (LPVOID) (LPCTSTR) strFormData, 
    strFormData.GetLength());
