when need subscription, login success or fail?

[flyingfoxlee]

When a site requires a subscription, how to confirm whether login was successful or not. Currently, calibre returns nothing no matter what I put the correct user profile or just anything.
I overwrite get_Browser as follows:

     def get_browser(self):
         br = BasicNewsRecipe.get_browser()
         if self.username is not None and self.password is not None:
             br.open('login site')
             br.select_form(name = 'mainLoginForm')
             br['username']   = self.username 
             br['password'] =  self.password 
             br.submit()
         return br

the login form is as follows
<form name="mainLoginForm" id="mainLoginForm" method="POST" action="" target="_self">

onclick="CheckLoginForm(); return false;"

returned_html = br.submit().read()

Then look for something like "Log Out" or Welcome" or whatever in the returned html to check if the login succeeded.

Thanks for the reply. there was nothing like that.
It seems as if it was still in the login page or redirecting .
the source of the form is as follows:

<dd><label>email address</label>
<input id="username" name="username" 
title="email" class="txt" onblur="UserCheck(this);" type="text">
</dd>
                        
<dd><label>pswd</label>
<input id="password" name="password" 
value="" class="txt" type="password"></dd>

<dd><label>&nbsp;</label>
<input onclick="CheckLoginForm(); return false;" id="sButton" 
src="http://somesite/file/other/login/images/btn_login.png" type="image"></dd>

Did I miss something in the get_browser function?

Many websites need some kind of extra trickery to get the login to work, like a special cookie or hidden form value you'll have to figure out what that is, use some kind of http inspector tool like live http headers for firefox and login using your browser, then investigate what happens.
