VC++的UNICODE工程和多字节字符集的HTTP请求

CString CServerSession::httpGetRequest(CString url){CInternetSession m_InetSession;CString strHtml;try{CHttpFile* pFile =(CHttpFile*)m_InetSession.OpenURL(url);if (pFile!=NULL){DWORD statusCode;  pFile->QueryInfoStatusCode(statusCode);  if (statusCode==HTTP_STATUS_OK)  { CString strLine;while (pFile->ReadString(strLine)>0)strHtml +=  strLine;}}m_InetSession.Close();pFile->Close();delete pFile;}catch (CInternetException* e){TCHAR info[1024] = {0};e->GetErrorMessage(info,1024);AfxMessageBox(info);}catch (CMemoryException* e){TCHAR info[1024] = {0};e->GetErrorMessage(info,1024);AfxMessageBox(info);}catch (CFileException* e){TCHAR info[1024] = {0};e->GetErrorMessage(info,1024);AfxMessageBox(info);}catch (CException* e){TCHAR info[1024] = {0};e->GetErrorMessage(info,1024);AfxMessageBox(info);}return strHtml;}CString CServerSession::httpPostRequest(CString requestData,CString pageUrl){CInternetSession m_InetSession;     //设置不缓冲CHttpConnection* pServer = NULL;CHttpFile* pFile = NULL;CString strHtml;//POST过去的数据requestDatatry{INTERNET_PORT nPort; //端口nPort=80;pServer = m_InetSession.GetHttpConnection("127.0.0.1", nPort);pFile = pServer->OpenRequest(CHttpConnection::HTTP_VERB_POST,pageUrl);pFile->AddRequestHeaders("Content-Type: application/x-www-form-urlencoded");pFile->AddRequestHeaders("Accept: */*");pFile->SendRequestEx(requestData.GetLength());pFile->WriteString(requestData);pFile->EndRequest();DWORD dwRet;pFile->QueryInfoStatusCode(dwRet);if (dwRet == HTTP_STATUS_OK){CString strLine;while (pFile->ReadString(strLine)>0)strHtml +=  strLine;}m_InetSession.Close();pFile->Close();pServer->Close();delete pFile;delete pServer;}catch (CInternetException* e){TCHAR info[1024] = {0};e->GetErrorMessage(info,1024);AfxMessageBox(info);}catch (CMemoryException* e){TCHAR info[1024] = {0};e->GetErrorMessage(info,1024);AfxMessageBox(info);}catch (CFileException* e){TCHAR info[1024] = {0};e->GetErrorMessage(info,1024);AfxMessageBox(info);}catch (CException* e){TCHAR info[1024] = {0};e->GetErrorMessage(info,1024);AfxMessageBox(info);}return strHtml;}

以上是字节字符集的

下面是UNICODE工程的

CString CServerSession::httpGetRequest(CString url){CInternetSession m_InetSession;CString strHtml;try{CHttpFile* pFile =(CHttpFile*)m_InetSession.OpenURL(url);if (pFile!=NULL){DWORD statusCode;  pFile->QueryInfoStatusCode(statusCode);  if (statusCode==HTTP_STATUS_OK)  { TCHAR buf[1024]= {0};char tmp[2048] = {0};while(pFile->ReadString(buf, 1024)) {for(int i=0, j=0; i<lstrlen(buf); i++, j+=2){tmp[j] = LOBYTE(buf[i]);//取字的低字节tmp[j+1] = HIBYTE(buf[i]);//取字的高字节}CString ss(tmp);strHtml+=ss;}}}m_InetSession.Close();pFile->Close();delete pFile;}catch (CInternetException* e){TCHAR info[1024] = {0};e->GetErrorMessage(info,1024);}catch (CMemoryException* e){TCHAR info[1024] = {0};e->GetErrorMessage(info,1024);}catch (CFileException* e){TCHAR info[1024] = {0};e->GetErrorMessage(info,1024);}catch (CException* e){TCHAR info[1024] = {0};e->GetErrorMessage(info,1024);}return strHtml;}CString CServerSession::httpPostRequest(char* requestData,CString pageUrl){CInternetSession m_InetSession;     //设置不缓冲CHttpConnection* pServer = NULL;CHttpFile* pFile = NULL;CString strHtml;//POST过去的数据requestDatatry{INTERNET_PORT nPort; //端口nPort=80;pServer = m_InetSession.GetHttpConnection(SERVER_URL, nPort);pFile = pServer->OpenRequest(CHttpConnection::HTTP_VERB_POST,pageUrl);pFile -> AddRequestHeaders(_T("Content-Type: application/x-www-form-urlencoded")); pFile -> AddRequestHeaders(_T("Accept: */*"));pFile->SendRequest(NULL,NULL,requestData,(DWORD)strlen(requestData));DWORD dwRet;pFile->QueryInfoStatusCode(dwRet);if (dwRet == HTTP_STATUS_OK){TCHAR buf[1024]= {0};char tmp[2048] = {0};while(pFile->ReadString(buf, 1024)) {for(int i=0, j=0; i<lstrlen(buf); i++, j+=2){tmp[j] = LOBYTE(buf[i]);//取字的低字节tmp[j+1] = HIBYTE(buf[i]);//取字的高字节}strHtml+=UTF8ToUnicode(tmp);}}m_InetSession.Close();pFile->Close();pServer->Close();delete pFile;delete pServer;}catch (CInternetException* e){TCHAR info[1024] = {0};e->GetErrorMessage(info,1024);}catch (CMemoryException* e){TCHAR info[1024] = {0};e->GetErrorMessage(info,1024);}catch (CFileException* e){TCHAR info[1024] = {0};e->GetErrorMessage(info,1024);}catch (CException* e){TCHAR info[1024] = {0};e->GetErrorMessage(info,1024);}return strHtml;}
