How to receive url parameter value using python-CodePudding

I am new to python, i want to know in python how to receive the URL parameter value? I tried with below code, but

import urllib.parse as urlparse
from urllib.parse import urlencode

url = "http://domainanme.com/api/filename.py?para_name=value"


url_parts = list(urlparse.urlparse(url))

query = dict(urlparse.parse_qsl(url_parts[4]))

Using python i am unable to receive para_name = value But in PHP can easily get URL parameter value using $_GET['para_name'], with out knowing the full URL, but in python how do i know the full URL with params

Note: i want to do using core python without any Python framework

You can try this:

  import urllib.parse as urlparse
  from urllib.parse import urlencode

  url = "http://domainanme.com/api/filename.py?para_name=value"

  url_parts = urlparse.urlparse(url)

  query = urlparse.parse_qs(url_parts.query)

  value = query['para_name']

You can access the query string from the query attribute of the ParseResult object. Then just access the value by key name.

I hope this will help you

cgi.FieldStorage()

It returns a dictionary with the key as the field and value as its value.

Without any python framework, you can get the URL parameter value

Sample code

import cgi
import cgitb; cgitb.enable() # Optional; for debugging only

print("Content-Type: text/html")

arguments = cgi.FieldStorage()
for i in arguments.keys():

    print(arguments[i].value)

Example: save this file as test.py and execute it in your browser like http://youdomainname.com/test.py?name=john in the browser, you can see the result as a john
