I would like to login to my facebook account with Indy. The version is 9.00.10 and I use OpenSSL with TIDHTTP and assigned a cookie manager to it. Everything works fine (I can send a POST request a GET, etc.)
I sniffed the actual login to facebook and I have the following information:
UserAgent: Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.2) Gecko/20100115 Firefox/3.6 (.NET CLR 3.5.30729)
There are several POST parameters:
The post is made on https://www.facebook.com/login.php?login_attempt=1. However when I try to login it returns that I have entered an incorrect eMail. I'm sure I used the right eMail and Password.
Here is my code:
procedure TForm1.Button1Click(Sender: TObject);
var
TEST : STRING;
lParamList: TStringList;
i : Integer;
begin
lParamList := TStringList.Create;
lparamlist.Add('lsd=AVoBzJ5G');
lparamlist.Add('email=myeMail%40mysite.com');
lparamlist.Add('pass=mypass');
lparamlist.Add('default_persistent=0');
lparamlist.Add('timezone=240');
lparamlist.Add('lgnrnd=210302_FeQV');
lparamlist.Add('lgnjs=1367035381');
lparamlist.Add('locale=en_US');
IDHTTP1.Request.UserAgent := 'Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.2) Gecko/20100115 Firefox/3.6 (.NET CLR 3.5.30729)';
Test := IdHTTP1.Get('https://www.facebook.com'); // To get the first cookies.
for i := 0 to IDHTTP1.CookieManager.CookieCollection.Count - 1 do begin
ShowMessage(IDHTTP1.CookieManager.CookieCollection.Items[i].CookieText); // Show me the cookies.
end;
TEST := IDHTTP1.Post('https://www.facebook.com/login.php?login_attempt=1', lParamList);
StrToFile ('text.html', test);
ShellExecute (0, 'open', 'text.html', '', '', SW_SHOW);
end;
I used the parameters that I got from LiveHTTPHeaders. How would I successfully login to facebook with Indy?
EDIT: Tried this with XE2 and Indy 10 but I get the 'incorrect email' error:

If the hoForceEncodeParams
flag is enabled in the TIdHTTP.HTTPOptions
property (which it is by default), then you need to fill the posted TStringList
with un-encoded values. TIdHTTP.Post()
will then encode the values for you when transmitting them.
Assuming the hoForceEncodeParams
flag is enabled, lparamlist.Add('email=myeMail%40mysite.com');
would be transmitted as email=myeMail%2540mysite.com
because the %
character gets encoded as %25
. Facebook would decode that as email=myeMail%40mysite.com
and reject it as an invalid email.
You can either:
disable the hoForceEncodeParams
flag so the TStringList
values get transmitted as-is. You would then be responsible for encoding them manually.
leave the hoForceEncodeParams
flag enabled and change lparamlist.Add('email=myeMail%40mysite.com');
to lparamlist.Add('[email protected]');
instead. TIdHTTP.Post()
in Indy 9 will then transmit it as [email protected]
because Indy 9 does not encode the @
character. That may or may not work, depending on how lenient Facebook is.
If you upgrade to Indy 10, TIdHTTP.Post()
will encode the @
character as %40
as expected when the hoForceEncodeParams
flag is enabled.
