my CHttpFile::SendRequest() timeout when sending request to google translator

[m_code]

I want to use google translator api through an application I wrote the following code but CHttpFile::SendRequest() method always time out I could n't found what's my problem. Can any one help me?

CString szTranReq(L"/translate_a/t?client=t&sl=en&tl=tr");

CString szText(L"text=Hello");

CString szServer(L"www.google.com");

DWORD inetPort = 80;




CInternetSession inetSession(::AfxGetAppName(), 1, PRE_CONFIG_INTERNET_ACCESS, NULL, NULL, NULL);

inetSession.SetOption(INTERNET_OPTION_CONNECT_TIMEOUT, 1000 * 3);
inetSession.SetOption(INTERNET_OPTION_CONNECT_BACKOFF, 1000);
inetSession.SetOption(INTERNET_OPTION_CONNECT_RETRIES, 1);

CHttpConnection* pInetHttpConnection = inetSession.GetHttpConnection(szServer, inetPort, NULL, NULL);


CHttpFile* pHttpFile = pInetHttpConnection->OpenRequest(
CHttpConnection::HTTP_VERB_POST,
szTranReq, NULL, 1, NULL, NULL,
INTERNET_FLAG_EXISTING_CONNECT | INTERNET_FLAG_DONT_CACHE);



pHttpFile->AddRequestHeaders(L"Host: www.google.com\r\n", HTTP_ADDREQ_FLAG_ADD_IF_NEW);
pHttpFile->AddRequestHeaders(L"User-Agent: Mozilla/5.0\r\n", HTTP_ADDREQ_FLAG_ADD_IF_NEW);
pHttpFile->AddRequestHeaders(L"Accept-Encoding: deflate\r\n", HTTP_ADDREQ_FLAG_ADD_IF_NEW);
pHttpFile->AddRequestHeaders(L"content-length: 5\r\n", HTTP_ADDREQ_FLAG_ADD_IF_NEW);
pHttpFile->AddRequestHeaders(L"Connection: Close\r\n", HTTP_ADDREQ_FLAG_ADD_IF_NEW);

pHttpFile->SendRequest(); //always timeout

Any one could help me with this problem?
a program with the same coding in QT Works fine

You are trying to translate the text "Hello", but I don't see where you actually pass it to the server.
You just declare the szText variable, but never use it.

thanks You were right.
But unfortunately the following code failed too with Http Status 400(Bad Request)

CString szTranReq(L"/translate_a/t?client=t&sl=en&tl=tr");

CString szText(L"text=Hello");

CString szServer(L"www.google.com");

DWORD inetPort = 80;




CInternetSession inetSession(::AfxGetAppName(), 1, PRE_CONFIG_INTERNET_ACCESS, NULL, NULL, NULL);

inetSession.SetOption(INTERNET_OPTION_CONNECT_TIMEOUT, 1000 * 3);
inetSession.SetOption(INTERNET_OPTION_CONNECT_BACKOFF, 1000);
inetSession.SetOption(INTERNET_OPTION_CONNECT_RETRIES, 1);

CHttpConnection* pInetHttpConnection = inetSession.GetHttpConnection(szServer, inetPort, NULL, NULL);


CHttpFile* pHttpFile = pInetHttpConnection->OpenRequest(
CHttpConnection::HTTP_VERB_POST,
szTranReq, NULL, 1, NULL, NULL,
INTERNET_FLAG_EXISTING_CONNECT | INTERNET_FLAG_DONT_CACHE);



pHttpFile->AddRequestHeaders(L"Host: www.google.com\r\n", HTTP_ADDREQ_FLAG_ADD_IF_NEW);
pHttpFile->AddRequestHeaders(L"User-Agent: Mozilla/5.0\r\n", HTTP_ADDREQ_FLAG_ADD_IF_NEW);
pHttpFile->AddRequestHeaders(L"Accept-Encoding: deflate\r\n", HTTP_ADDREQ_FLAG_ADD_IF_NEW);
pHttpFile->AddRequestHeaders(L"content-length: 10\r\n", HTTP_ADDREQ_FLAG_ADD_IF_NEW);
pHttpFile->AddRequestHeaders(L"Connection: Close\r\n", HTTP_ADDREQ_FLAG_ADD_IF_NEW);

pHttpFile->SendRequestEx(szText.GetLength(),HSR_INITIATE,1);
pHttpFile->WriteString(szText);
pHttpFile->EndRequest();


DWORD dwRet;
pHttpFile->QueryInfoStatusCode(dwRet); ///dwRet is always 400

Actually I Want to implement the following code wriiten in Qt to MFC:


QString url = QString("/translate_a/t?client=t&sl=en&tl=tr");


QHttpRequestHeader header = QHttpRequestHeader("POST", url, 1, 1);
header.setValue("Host", "www.google.com");
header.setValue("User-Agent", "Mozilla/5.0");
header.setValue("Accept-Encoding", "deflate");
header.setContentLength( text.length() );
header.setValue("Connection", "Close");

QByteArray ba("text=");
ba.append( text );

a_Http->setHost("www.google.com");
a_Http->request(header,ba);

a_done.exec(QEventLoop::AllEvents|QEventLoop::WaitForMoreEvents);

QString out = QString::fromUtf8( a_Http->readAll() );
