mChat add message

[tumba25]

Ok, great. I'll set up a test site. phpBB 3.0 or 3.1?

[deejay_xb]

phpbb 3.0.12

[tumba25]

Now it's up, sorry for the delay. That forum is only up temporarily and will be deleted as soon as your app is done or development stops for some other reason.

You will need to register.

Code: Select all

mchat.dark-side.net

ty, but i need to find how the autogenerate form_token is made..
maybe rich can help?

[tumba25]

maybe rich can help?

Hope so. I'll play around with the Android studio later to see if I can get the same result as mChat.

The form token is generated within the includes/functions.php file within the add_form_key function which is done within mchat.php file via add_form_key('mchat_posting');

[deejay_xb]

this is in functions.php

Code: Select all

$now = time();
	$token_sid = ($user->data['user_id'] == ANONYMOUS && !empty($config['form_token_sid_guests'])) ? $user->session_id : '';
	$token = sha1($now . $user->data['user_form_salt'] . $form_name . $token_sid);

time() is current php time;
$token_sid = $user->session_id;
$form_name = 'mchat_posting';

so $token = sha1( time() $user->data['user_form_salt'] mchat_posting $user->session_id )

is this ok?

edit:
example:
time() = 1421591728
user_form_salt = 68cb19d150c03331
form_name = mchat_posting
user_session_id = 866c119c443d2828691acc126bb92291
token = 142159172868cb19d150c03331mchat_posting866c119c443d2828691acc126bb92291

correct or not?

Ok, played a bit with this, here is what I found.

Code: Select all

$token_sid = ($user->data['user_id'] == ANONYMOUS && !empty($config['form_token_sid_guests'])) ? $user->session_id : '';

That makes $token_sid empty for logged in users. It only holds a value for guests. And the form name is mchat_posting.

This is the data needed to create the token.

Code: Select all

$now       = time();
$form_salt = $user->data['user_form_salt'];
$form_name = 'mchat_posting';
$token_sid = ''; 

$token = sha1($now . $form_salt . $form_name . $token_sid);

[tumba25]

You will also need $config['form_token_lifetime']. If it's -1, then you don't need to bother with the form creation time. If not, you need to.

Code: Select all

$max = max(30, $config['form_token_lifetime']);
$diff = time() - abs($form_creation_time);
if ($diff <= $max) {
    // Good to go.
} else {
    // Form to old, need a new one.
}

@RMcGirr83: Do you have a non mini version of mchat_ajax_mini.js?

@deejay_xb: You really need to get the form token and form created time from mChat. The best would have been a API, but since the author didn't think about that you need to scrape it from the site.

@RMcGirr83: Do you have a non mini version of mchat_ajax_mini.js?

It is in the download of the mod within the contrib directory

So it is, thanks.

[deejay_xb]

ok so token is sha1('time''user_form_salt''mchat_posting')

and it seems that is correct:

Code: Select all

time() = 1421591728
user_form_salt = 68cb19d150c03331
form_name = postform
string = 142159172868cb19d150c03331mchat_posting

token = sha1(142159172868cb19d150c03331mchat_posting)
token = 379ad196d7b4b446d96b882f3ce231ddb50a90fc

and

Code: Select all

mchat autogenerated form_token = 379ad196d7b4b446d96b882f3ce231ddb50a90fc

[RMcGirr83]

The code you posted doesn't look anything like what tumba25 posted. Well it does but it isn't correct. Use what tumba25 posted.

[deejay_xb]

do i need something else because:

Code: Select all

http://www.gameforest.ro/mchat.php?mode=add&message=testdecacat2&addbbcode20=100&addbbcode_custom=%23&creation_time=1421350220&form_token=cc82c5c4493aa22shjewja6800618817930fe57

does not work.. it does nothing, no error, no message in mchat..
