[ Python 常見問題 ] requests - How to “log in” to a website?

Question
I am trying to post a request to log in to a website using the Requests module in Python but its not really working.

How-To
If the information you want is on the page you are directed to immediately after login, below is the simple code:

view plaincopy to clipboardprint?

1. payload = {'inUserName': 'USERNAME/EMAIL', 'inUserPass': 'PASSWORD'}  
2. url = 'http://www.locationary.com/home/index2.jsp'  
3. requests.post(url, data=payload)  

Assuming your login attempt was successful, you can simply use the session instance to make further requests to the site. The cookie that identifies you will be used to authorize the requests:

view plaincopy to clipboardprint?

1. import requests  
2.   
3. # Fill in your details here to be posted to the login form.  
4. payload = {  
5.     'inUserName': 'username',  
6.     'inUserPass': 'password'  
7. }  
8.   
9. # Use 'with' to ensure the session context is closed after use.  
10. with requests.Session() as s:  
11.     p = s.post('LOGIN_URL', data=payload)  
12.     # print the html returned or something more intelligent to see if it's a successful login page.  
13.     print p.text  
14.   
15.     # An authorised request.  
16.     r = s.get('A protected web page url')  
17.     print r.text  
18.         # etc...
