C++ 以POST方式向网页提交数据

示例代码如下:


#include 
#include 
#include  //定义了MFC CInternetSession类等

bool PostHttpPage(const std::string& hostName, const std::string& pathName, const std::string& postData)
{
    using namespace std;

    CInternetSession session("your app agent name");

    try
    {
        INTERNET_PORT nPort = 80;
        DWORD dwRet = 0;

        CHttpConnection* pServer = session.GetHttpConnection(hostName.c_str(), nPort);
        CHttpFile* pFile = pServer->OpenRequest(CHttpConnection::HTTP_VERB_POST, pathName.c_str());

        CString strHeaders = "Content-Type: application/x-www-form-urlencoded"; // 请求头

        //开始发送请求

        pFile->SendRequest(strHeaders,(LPVOID)postData.c_str(),postData.size());
        pFile->QueryInfoStatusCode(dwRet);

        if (dwRet == HTTP_STATUS_OK)
        {
            CString result, newline;

            while(pFile->ReadString(newline))
            {//循环读取每行内容
                result += newline+"\r\n";
            }

            std::cout<GetErrorMessage(pszError, 200);

        std::cout<

                    
THE END
