"Python Network data Collection" The Nineth Chapter: cross-form and login window

1. Python Requests Library:

The requests library is a Python third-party library that specializes in handling complex HTTP requests, cookies, headers (response headers and request headers), and so on.

2. Submit a basic form:

1 ImportRequests2 3params = {'FirstName':'Ryan','LastName':'Mitchell'}4R=requests.post ("http://pythonscraping.com/files/processing.php", Data=params)5 6 Print(R.text)

Any POST request for the form actually occurs on this page, not the page on which the form itself is located. Remember: The purpose of the HTML form is simply to help visitors to the site send a reasonably formatted request to the server to request a page that does not appear. Unless you're studying the design style of the request, you don't need to spend too much time on the page where the form is located.
