WinHTTP Error Invalid URL

c++, winhttp

Solution

`WinHttpConnect` takes only the hostname part. You should pass the rest of the path to `WinHttpOpenRequest` (the third parameter, `pwszObjectName`):

WinHttpOpenRequest( hConnect, L"GET", L"/questions", NULL,WINHTTP_NO_REFERER, 
       WINHTTP_DEFAULT_ACCEPT_TYPES, 
      WINHTTP_FLAG_SECURE );

Problem

How do you specify a URL with path for example: `http://stackoverflow.com/questions`. The following works but not with the URL specified above in example. ``` LPCWSTR useragent = L"Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.2.12) Gecko/20101026 Firefox/3.6.12 GTB7.1 ( .NET CLR 3.5.30729)"; DWORD dwSize = 0; DWORD dwDownloaded = 0; LPSTR pszOutBuffer; BOOL bResults = FALSE; HINTERNET hSession = NULL, hConnect = NULL, hRequest = NULL; // Use WinHttpOpen to obtain a session handle. hSession = WinHttpOpen(useragent, WINHTTP_ACCESS_TYPE_DEFAULT_PROXY, WINHTTP_NO_PROXY_NAME, WINHTTP_NO_PROXY_BYPASS, 0 ); // Specify an HTTP server. if( hSession ) hConnect = WinHttpConnect( hSession, L"www.stackoverflow.com", INTERNET_DEFAULT_HTTPS_PORT, 0 ); // Create an HTTP request handle. if( hConnect ) hRequest = WinHttpOpenRequest( hConnect, L"GET", NULL, NULL,WINHTTP_NO_REFERER, WINHTTP_DEFAULT_ACCEPT_TYPES, WINHTTP_FLAG_SECURE ); // Send a request. if( hRequest ) bResults = WinHttpSendRequest(hRequest, WINHTTP_NO_ADDITIONAL_HEADERS, 0, WINHTTP_NO_REQUEST_DATA, 0, 0, 0 ); // End the request. if( bResults ) bResults = WinHttpReceiveResponse( hRequest, NULL ); ```
