How to check the connectivity for a URL in python-CodePudding

My requirement is almost same as Requests — how to tell if you're getting a success message?

But I need to print error whenever I could not reach the URL..Here is my try..

# setting up the URL and checking the conection by printing the status

url = 'https://www.google.lk'

try:
    page = requests.get(url)
    print(page.status_code)
except requests.exceptions.HTTPError as err:
    print("Error")

The issue is rather than printing just "Error" it prints a whole error msg as below.

Traceback (most recent call last):
  File "testrun.py", line 22, in <module>
    page = requests.get(url)
  File "/root/anaconda3/envs/py36/lib/python3.6/site-packages/requests/api.py", line 76, in get
    return request('get', url, params=params, **kwargs)
  File "/root/anaconda3/envs/py36/lib/python3.6/site-packages/requests/api.py", line 61, in request
    return session.request(method=method, url=url, **kwargs)
  File "/root/anaconda3/envs/py36/lib/python3.6/site-packages/requests/sessions.py", line 530, in request
    resp = self.send(prep, **send_kwargs)
  File "/root/anaconda3/envs/py36/lib/python3.6/site-packages/requests/sessions.py", line 643, in send
    r = adapter.send(request, **kwargs)
  File "/root/anaconda3/envs/py36/lib/python3.6/site-packages/requests/adapters.py", line 516, in send
    raise ConnectionError(e, request=request)
requests.exceptions.ConnectionError: HTTPSConnectionPool(host='docs.microsoft.com', port=443): Max retries exceeded with url: /en-us/microsoft-365/enterprise/urls-and-ip-address-ranges?view=o365-worldwide (Caused by NewConnectionError('<urllib3.connection.VerifiedHTTPSConnection object at 0x7ff91a543198>: Failed to establish a new connection: [Errno 110] Connection timed out',))

Can someone show me how should I modify my code to just print "Error" only if there is any issue? Then I can extend it to some other requirement.

CodePudding user response：

You're not catching the correct exception.

import requests


url = 'https://www.googlggggggge.lk'

try:
    page = requests.get(url)
    print(page.status_code)
except (requests.exceptions.HTTPError, requests.exceptions.ConnectionError):
    print("Error")

you can also do except Exception, however note that Exception is too broad and is not recommended in most cases since it traps all errors

CodePudding user response：

You need to either use a general exception except or catch all exceptions that requests module might throw, e.g. except (requests.exceptions.HTTPError, requests.exceptions.ConnectionError).
