[Delphi, Lazarus] WiniNet - jak się łączyć przez proxy ?
Siemanko, witam w mojej kuchni. Potrzebuję pomocy w jaki sposób mogę za pomocą tych o to moich funkcji łączyć się przez proxy ? gdzie tu umieścić ip/port ? bo trochę ciemny jestem jeśli o takie rzeczy chodzi (hehe moja pierwsza apka - bot - internetowy)
moja funkcja
Kod:
Function sslInet(Const AServer, AUrl, AData : AnsiString; blnSSL:Boolean = True): AnsiString;
var
aBuffer : Array[0..4096] of Char;
Header : TStringStream;
BufStream : TMemoryStream;
sMethod : AnsiString;
BytesRead : Cardinal;
pSession : HINTERNET;
pConnection : HINTERNET;
pRequest : HINTERNET;
begin
Result := '';
pSession := InternetOpen(nil, INTERNET_OPEN_TYPE_PRECONFIG, nil, nil, 0);
if Assigned(pSession) then
try
case blnSSL of
True : pConnection := InternetConnect(pSession, PChar(AServer), INTERNET_DEFAULT_HTTPS_PORT, nil, nil, INTERNET_SERVICE_HTTP, 0, 0);
False : pConnection := InternetConnect(pSession, PChar(AServer), INTERNET_DEFAULT_HTTP_PORT, nil, nil, INTERNET_SERVICE_HTTP, 0, 0);
end;
if Assigned(pConnection) then
try
if (AData = '') then
sMethod := 'GET'
else
sMethod := 'POST';
case blnSSL of
True : pRequest := HTTPOpenRequest(pConnection, PChar(sMethod), PChar(AURL), nil, nil, nil, INTERNET_FLAG_SECURE or INTERNET_FLAG_KEEP_CONNECTION, 0);
False : pRequest := HTTPOpenRequest(pConnection, PChar(sMethod), PChar(AURL), nil, nil, nil, INTERNET_SERVICE_HTTP, 0);
end;
if Assigned(pRequest) then
try
Header := TStringStream.Create('');
with Header do
begin
WriteString('Host: ' + AServer + sLineBreak);
WriteString('Content-Type: application/x-www-form-urlencoded'+SlineBreak);
WriteString('User-Agent: Firefox/3.0.10'+SLineBreak);
WriteString('Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8'+SLineBreak);
WriteString('Accept-Language: en-us,en;q=0.5' + SLineBreak);
WriteString('Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7'+SLineBreak);
WriteString('Keep-Alive: 300'+ SLineBreak);
WriteString('Connection: keep-alive'+ SlineBreak+SLineBreak);
end;
HttpAddRequestHeaders(pRequest, PChar(Header.DataString), Length(Header.DataString), HTTP_ADDREQ_FLAG_ADD);
if HTTPSendRequest(pRequest, nil, 0, Pointer(AData), Length(AData)) then
begin
BufStream := TMemoryStream.Create;
try
while InternetReadFile(pRequest, @aBuffer, SizeOf(aBuffer), BytesRead) do
begin
if (BytesRead = 0) then Break;
BufStream.Write(aBuffer, BytesRead);
end;
aBuffer[0] := #0;
BufStream.Write(aBuffer, 1);
Result := PChar(BufStream.Memory);
finally
FreeAndNil(BufStream);
end;
end;
finally
InternetCloseHandle(pRequest);
FreeAndNil(Header);
end;
finally
InternetCloseHandle(pConnection);
end;
finally
InternetCloseHandle(pSession);
end;
end;
Jeśli ma to jakieś znaczenie to łączę się przez https [hail tibia.com]
