一、GET 數(shù)據(jù)，下載網(wǎng)頁，文件等，用于可下載的文件，不能用于服務(wù)端運(yùn)行的程序，比如.aspx文件等，否則會(huì)返回500錯(cuò)誤。
CString?strSentence,?strWriteName="1.htm";
????CString?strFileName="http://localhost/InDesign/"?+?strWriteName;
????CInternetSession?sess;
????CHttpFile*?fileGet;
????try
????
{
????????fileGet=(CHttpFile*)sess.OpenURL(strFileName);
????}
????catch(CException*?e)
????{
????????fileGet?=?0;
????????throw;
????}????
????if(fileGet)
????{
????????DWORD?dwStatus;
????????DWORD?dwBuffLen?=?sizeof(dwStatus);
????????BOOL?bSuccess?=?fileGet->QueryInfo(HTTP_QUERY_STATUS_CODE|HTTP_QUERY_FLAG_NUMBER,?&dwStatus,?&dwBuffLen);
????????if(?bSuccess?&&?dwStatus>=?200&&?dwStatus<300?)?
????????{?
????????????CStdioFile?fileWrite;?
????????????if(fileWrite.Open(strWriteName,?CFile::modeWrite|CFile::modeCreate))
????????????{?
????????????????while(fileGet->ReadString(strSentence))
????????????????{
????????????????????fileWrite.WriteString(strSentence+"\n");
????????????????}
????????????????fileWrite.Close();
????????????????AfxMessageBox("下載完畢");
????????????}
????????????else
????????????{
????????????????AfxMessageBox("本地文件"+strWriteName+"打開出錯(cuò).");?
????????????}
????????}
????????else?
????????{
????????????strSentence.Format("打開網(wǎng)頁文件出錯(cuò)，錯(cuò)誤碼：%d",?dwStatus);
????????????AfxMessageBox(strSentence);
????????}
????????fileGet->Close();
????????delete?fileGet;
????}
????else
????????AfxMessageBox("不能找到網(wǎng)頁文件！");
????sess.Close();二、POST 數(shù)據(jù)，比如用于提交注冊(cè)信息等
CString?strHttpName="http://localhost/TestReg/RegForm.aspx";?//?需要提交數(shù)據(jù)的頁面
????CString?strFormData?=?"username=abc&password=123";????//?需要提交的數(shù)據(jù)
????CInternetSession?sess;
????CHttpFile*?fileGet;
????CString?strHeaders?=?_T("Content-Type:?application/x-www-form-urlencoded");?//?請(qǐng)求頭
????try
????{
????????fileGet=(CHttpFile*)sess.OpenURL(strHttpName);//打開文件
????}
????catch(CException*?e)
????{
????????fileGet?=?0;
????????throw;
????}
????CString?strSentence,?strGetSentence?=?"";
????if(fileGet)
????{
????????DWORD?dwStatus;
????????DWORD?dwBuffLen?=?sizeof(dwStatus);
????????BOOL?bSuccess?=?fileGet->QueryInfo(HTTP_QUERY_STATUS_CODE|HTTP_QUERY_FLAG_NUMBER,?&dwStatus,?&dwBuffLen);
????????if(?bSuccess?&&?dwStatus>=?200?&&dwStatus<300?)
????????{?
????????????BOOL?result?=?fileGet->SendRequest(strHeaders,?(LPVOID)(LPCTSTR)strFormData,?strFormData.GetLength());
????????????while(fileGet->ReadString(strSentence))????//?讀取提交數(shù)據(jù)后的返回結(jié)果
????????????{
????????????????strGetSentence?=?strGetSentence?+?strSentence?+?char(13)?+?char(10);
????????????}
????????????AfxMessageBox(strGetSentence);?//?顯示返回網(wǎng)頁內(nèi)容
????????}
????????else?
????????{
????????????strSentence.Format("POST出錯(cuò)，錯(cuò)誤碼：%d",?dwStatus);
????????????AfxMessageBox(strSentence);
????????}
????????
????????fileGet->Close();
????????delete?fileGet;
????}
????else
????????AfxMessageBox("不能找到網(wǎng)頁文件！");
