Test the given page is found or not on the server Using Python

In this article, we are going to write a Python script to test the given page is found or not on the server. We will see various methods to do the same.

Method 1: Using Urllib.

Urllib is a package that allows you to access the webpage with the program.

Installation:

pip install urllib

Approach:

• Import module
• Pass the URL in urllib.request() reading URLs
• Now check with urllib.error containing the exceptions raised by urllib.request

Implementation:

Python3

# import module
from urllib.request import urlopen
from urllib.error import *

# try block to read URL
try:
    html = urlopen("https://www.geeksforgeeks.org/")

# except block to catch
# exception
# and identify error
except HTTPError as e:
    print("HTTP error", e)

except URLError as e:
    print("Opps ! Page not found!", e)

else:
    print('Yeah !  found ')

Output:

Yeah !  found

Method 2: Using requests

Request allows you to send HTTP/1.1 requests extremely easily. This module also does not come built-in with Python. To install this type the below command in the terminal.

Installation:

pip install requests

Approach:

• Import module
• Pass the Url into requests.head()
• If response.status_code == 200 then server is up
• if response.status_code == 404 then server in down

Implementation:

Python3

# import module
import requests

# create a function
# pass the url
def url_ok(url):

    # exception block
    try:

        # pass the url into
        # request.hear
        response = requests.head(url)

        # check the status code
        if response.status_code == 200:
            return True
        else:
            return False
    except requests.ConnectionError as e:
        return e

# driven code
url = "https://www.geeksforgeeks.org/"
url_ok(url)

Output:

True
