Note: Send an HTTP message using the Python emulation browser

Python's own urllib,urllib2 can be very convenient to do HTTP operations, after we submit a message request in HTTP, it is possible to see the return of the error "403 Forbidden", which is the request of the site to prevent, so we need to disguise themselves as a simulator. In this case, you can add headers={' user-agent ': user-agent, ' Cookie ': cookie}, note that the operation of the website needs to login account, you need to add a cookie, these two values can be viewed through Chrome's developer tools:

Add them up, then add them to the request value:

req = Urllib2. Request (url = req_url,data = trans_data_urlencode,headers=headers)

This will allow you to simulate the browser sending the message.
