You can implement one function, first include the header file AFXINET.H
The following is the required code.
Bool cdownloaddlg :: GetFromweb (lpstr purl, lpstr saveasfilepath) {cinternetSession session; // session time object)
ChttpConnection * pserver = null; // Point to the server address (URL)
Chttpfile * phttpfile = null; // http file pointer
CString strservername; // server name
CSTRING STROBJECT; / / Query Object Name (HTTP file)
Internet_port nport; // port
DWORD DWSERVICEPE; // Service Type
DWORD DWHTTPREQUESTFLAGS = // Request Sign
// Internet_flag_existing_connect;
Internet_flag_no_auto_redirect;
Const tchar szheaders [] = _ t ("accept: text / * / r / nuser-agent: httpclient / r / n");
BOOL OK = AFXPARSEURL (// lexical analysis
PURL, // is analyzed URL string
DWSERVICETYPE, // Service type, FTP, HTTP, etc.
STRSERVERNAME, // server name
Strobject, // URL query object
NPORT); // URL specified port, may be empty
OK = OK && // This example only considers the HTTP protocol
(dWServiceType ==
Internet_Service_HTTP);
IF (! ok)
{AFXMessageBox ("URL error"); // report error
Return False;
}
PServer = session.gethttpConnection (strserverName, nport); // Get server name
PHTTPFILE = PServer-> OpenRequest (chttpConnection :: http_verb_get, strobject, null, 1, null, null, dwhttpRequestflags);
/ / Send a request to the server, establish an HTTP connection,
/ / Establish the HTTP file pointer on this unit
PHTTPFILE-> AddRequestHeaders (Szheaders);
Phttpfile-> sendrequest (); // Send request
CSTDIOFILE F; // Output file object
IF (! f.Open (// Open Output File
SaveasfilePath, CFile :: ModeCreate | CFILE :: Modewrite | CFILE :: Typebinary))
{MessageBox ("Unable to open file");
Return False;
}
// Save the search result to the file below
TCHAR SZBUF [1024]; // Cache INT length = 0; long a = phttpfile-> getLength (); while (length = phttpfile-> read (szbuf, 1023)))
F.Write (SZBUF, Length);
f.close (); // after work
PHTTPFILE -> Close ();
PSERVER -> Close ();
IF (PHTTPFILE! = null) delete phttpfile;
IF (PServer! = null) delete PServer;
Session.close (); Return True;
}
