Python requests ошибка 401

You could have wrapped this in a function and used a decorator to evaluate the response and retry the auth on 401. Then you only need to decorate any function that requires this re-auth logic….

Update:
As requested, a code example. I’m afraid this one is an old piece of code, Python 2 based, but you’ll get the idea. This one will retry an http call a number of times as defined in settings.NUM_PLATFORM_RETRIES and will call a refresh_token on auth failures. you can adjust the use case and result to whatever.
You can then use this decorator around methods:

@retry_on_read_error
def some_func():
   do_something()



def retry_on_read_error(fn):
    """
    Retry Feed reads on failures
    If a token refresh is required it is performed before retry.
    This decorator relies on the model to have a refresh_token method defined, othewise it will fail
    """
    @wraps(fn)
    def _wrapper(self, *args, **kwargs):
        for i in range(settings.NUM_PLATFORM_RETRIES):
            try:
                res = fn(self, *args, **kwargs)

                try:
                    _res = json.loads(res)
                except ValueError:
                    # not a json response (could be local file read or non json data)
                    return res

                if 'error' in _res and _res['error']['status'] in (401, 400):
                    raise AccessRefusedException(_res['error']['message'])

                return res
            except (urllib2.URLError, IOError, AccessRefusedException) as e:
                if isinstance(e, AccessRefusedException):
                    self.refresh_token()
                continue
        raise ApiRequestFailed(
            "Api failing, after %s retries: %s" % (settings.NUM_PLATFORM_RETRIES, e), args, kwargs
        )

    return _wrapper

It doesn’t get any less ugly than this, I think:

import requests
from requests.auth import HTTPBasicAuth

response = requests.get('http://your_url')

if response.status_code == 401:    
    response = requests.get('http://your_url', auth=HTTPBasicAuth('user', 'pass'))

if response.status_code != 200:
    # Definitely something's wrong

You can use something like this

The 401 Error in Chrome,The 401 status code in the developer console in Chrome,The Internet Engineering Task Force (IETF) defines the error 401 Unauthorized as:,If you encounter an error code in the 400s, you know you’re dealing with a client-side (or browser-side) issue. While the problem may be happening within your browser, however, it doesn’t necessarily always mean that’s the culprit, which we’ll explain in more detail later.

Another method you can try to resolve the 401 error is flushing your Domain Name Server (DNS). While this is a rarer issue, it can be a possible cause, so it’s worth giving it a try if the first two solutions don’t work.

To do this in Windows, click on the Start button and type cmd into the search bar. Hit Enter, and the Command Prompt will open. Copy and paste the command ipconfig/flushdns, and then hit Enter again:

cmd

What I want to do is GET from a site and if that request returns a 401, then redo my authentication wiggle (which may be out of date) and try again. But I don’t want to try a third time, since that would be my authentication wiggle having the wrong credentials. Does anyone have a nice way of doing this that doesn’t involve properly ugly code, ideally in python requests library, but I don’t mind changing.,Consider returning an http status of 401, and a JSON object detailing the reason. If you’re using jQuery, that’ll drop you to the error() callback, which you can then parse your object.,I’m not familiar with PHP anymore, but this should work for just about any environment. You may have to suppress any automatic login form redirection though. In asp.net mvc the framework will see the 401 and push the default login form back, with a status of 200.,The above code will attempt to send all the POST requests at once. Despite the intention, it will be throttled by aiohttp.ClientSession’s TCP connector which allows a maximum of 100 simultaneous connections by default. To increase or remove this limitation, you must set a custom connector on the session.

It doesn’t get any less ugly than this, I think:

import requests
from requests.auth import HTTPBasicAuth

response = requests.get('http://your_url')

if response.status_code == 401:    
    response = requests.get('http://your_url', auth=HTTPBasicAuth('user', 'pass'))

if response.status_code != 200:
    # Definitely something's wrong

I get the exact same error when I try calling the Payment Processing Authorization endpoint.,Whenever I try to authenticate with Two Way SSL, I keep getting Error 401 code 9124. ,Using SoapUI, you can find the x-correlation-id in the Raw Tab of the response header.,I solved this by generating and importing my own CSR and private key.. I have still do not know why I could not get the auto generated own to work though.
