SendRequest function error

CString strHeaders = _T ("Content-Type: application / x-www-form-urlencoded"); // http protocol
CString strFormData;
strFormData.Format ("UserName =% s, circle);

CString serverName = _T ("127.0.0.1"); // ip
INTERNET_PORT nPort = 8088; // Port number
CString formAction = _T ("\\web\\Service.jsp");
CInternetSession session;
CHttpConnection * pConnection = session.GetHttpConnection (serverName, nPort);
CHttpFile * pFile = pConnection-> OpenRequest (CHttpConnection :: HTTP_VERB_POST, formAction);

// A fatal error may occur when the server is not open
BOOL result = pFile-> SendRequest (strHeaders, (LPVOID) (LPCTSTR) strFormData, strFormData.GetLength ()); // Send request
Ranch
CString strResult;
pFile-> ReadString (strResult);
strResult.TrimLeft ();
strResult.TrimRight ();
return atoi (strResult);

This code calls pFile-> SendRequest (strHeaders, (LPVOID) (LPCTSTR) strFormData, strFormData.GetLength ()); if the server is not turned on, a fatal error will occur. Ask the expert for a solution to the problem, thank you

Fatal error?
If it is not open, it should be a failure to send and return 0. .

I am also getting this one, there will be no fatal errors when using synchronization,
It’s just mine. Sometimes I get stuck when I run SendRequest. I want to use asynchronous, but I ran into it again.
The problem cannot be solved. If you are familiar with it, we can discuss it.

Fatal error, what error?
If pFile is not opened by the server, it is NULL, how can it go to SendRequest if the three-way handshake fails. . .

Is there a way to check whether it is connected to the server?

I also use sendreqest(). Some machines don’t block, and some are blocked. I don’t know how you guys solve it. Please ask me!

I am also very concerned about this. Recently I also used this thing to multi-thread the old error
