Question

I am quite new in python and trying to write a script to login to the page at http://ryushare.com/login.python.

I have try many attempt, but it fails to login and i have no idea why.
After login to the page, I wish to get the return of http://ryushare.com/file-manager.python

Here’s the code I try to attempt by reading the example from others.

import urllib, urllib2, cookielib
username = 'myusername'
password = 'mypassword'

cj = cookielib.CookieJar()
opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cj))
login_data = urllib.urlencode({'login' : username, 'password' : password})
opener.open('http://www.ryushare.com/login.python', login_data)
resp = opener.open('http://ryushare.com/file-manager.python')
print resp.read()

I check the source code of the login page, it said the username and password value is “login and password” so i change it.
I have try some other example which can be found here like google news feed, It also can not able to login : (

Answer 1

In the page’s source, we have the following HTML:

<form method="POST" action="http://ryushare.com/" name="FL">

You should be open()’ing the “action” page, e.g.

opener.open('http://ryushare.com/", login_data)
# Now you can interact with site

http://www.w3schools.com/html/html_forms.asp:

Submit Button

<input type="submit" /> defines a submit button.

A submit button is used to send form data to a server. The data is
sent to the page specified in the form’s action attribute. The file
defined in the action attribute usually does something with the
received input:

<form name="input" action="html_form_action.asp" method="get">
Username: <input type="text" name="user" /> <input type="submit"
value="Submit" /> </form>

How the HTML code above looks in a browser:

Username: (Entry box)

If you type some characters in the text field above, and
click the “Submit” button, the browser will send your input to a page
called “html_form_action.asp”. The page will show you the received
input.

Edit: Other Form Data

As can be seen in the comments, the OP still had trouble after applying this fix. The answer is that there are often hidden form tags, including the for the submit button. Include these tags’ data in your request as well as your username and password.
