WebForm Submission with Python

WebForm Submission in Python
Sometime
we need to interact with a webpage which needs some data to be submitted to the
server through the forms present in the html page.
These
types of webpages are mainly used for signing up for a new account or supplying
some information like name, registration number and mobile number etc. to
retrieve the result of an examination.
Python
provides a module requests which helps us to handle this type of requirement
gracefully using the POST method with some others required parameters.
Let’s
take an example to understand it in better way.
Example
In this example, we are trying to sign up
into a website and here we are providing user id and password.
Then after filling all the details we are printing the response what we
received from the website.
import requests
USERNAME_ID = 'signup-user-name'
PASSWORD_ID = 'signup-user-password'
USERNAME = 'username'
PASSWORD = 'userpassword'
SIGNUP_URL = 'https://codepad.org/login'
def submit_form():
"""Submit a form"""
payload = {ID_USERNAME : USERNAME, ID_PASSWORD : PASSWORD,}
resp = requests.get(SIGNUP_URL)
print("Response to GET request: %s" %resp.content)
resp = requests.post(SIGNUP_URL, payload)
print("Headers from a POST request response: %s" %resp.headers)
#print "HTML Response: %s" %resp.read()
if __name__ == '__main__':
submit_form()
When we run the above program, we get the below
mentioned response from the webpage−
Response to GET request: <!DOCTYPE html>
<html>
<head>
<meta http-equiv="content-type" content="text/html; charset=UTF-8">
<meta HTTP-EQUIV="Pragma" CONTENT="no-cache">
<meta HTTP-EQUIV="Expires" CONTENT="-1">
<title>Login - codepad</title>
<link href="/main.css" media="screen" rel="stylesheet" type="text/css" />
<style type="text/css">
</style>
<script src='https://www.google.com/recaptcha/api.js'></script>
<script>
function onRecaptcha(token) {
document.getElementById("editor-form").submit();
}
</script>
</head>
<body >
