Python 带身份验证的请求 (access_token)

Question

I am trying to use an API query in Python. From the command line I can use curl like so:

curl --header "Authorization:access_token myToken" https://website.example/id

This gives some JSON output. myToken is a hexadecimal variable that remains constant throughout.

I would like to make this call from python so that I can loop through different ids and analyze the output. Before authentication was needed I had done that with urllib2 . I have also taken a look at the requests module but couldn't figure out how to authenticate with it.

Answer 1

The requests package has a very nice API for HTTP requests, adding a custom header works like this ( source: official docs ):

>>> import requests
>>> response = requests.get(
... 'https://website.example/id', headers={'Authorization': 'access_token myToken'})

If you don't want to use an external dependency, the same thing using urllib2 of the standard library looks like this ( source: the missing manual ):

>>> import urllib2
>>> response = urllib2.urlopen(
... urllib2.Request('https://website.example/id', headers={'Authorization': 'access_token myToken'})

Answer 2

I had the same problem when trying to use a token with Github.

The only syntax that has worked for me with Python 3 is:

import requests

myToken = '<token>'
myUrl = '<website>'
head = {'Authorization': 'token {}'.format(myToken)}
response = requests.get(myUrl, headers=head)

Answer 3

>>> import requests
>>> response = requests.get('https://website.com/id', headers={'Authorization': 'access_token myToken'})

If the above doesnt work , try this:

>>> import requests
>>> response = requests.get('https://api.buildkite.com/v2/organizations/orgName/pipelines/pipelineName/builds/1230', headers={ 'Authorization': 'Bearer <your_token>' })
>>> print response.json()

Answer 4

import requests

BASE_URL = 'http://localhost:8080/v3/getPlan'
token = "eyJhbGciOiJSUzI1NiIsImtpZCI6ImR"

headers = {'Authorization': "Bearer {}".format(token)}
auth_response = requests.get(BASE_URL, headers=headers)

print(auth_response.json())

Output :

{
"plans": [
    {
        "field": false,
        "description": "plan 12",
        "enabled": true
    }
  ]
}

Have you tried the uncurl package ( https://github.com/spulec/uncurl )? You can install it via pip, pip install uncurl . Your curl request returns:

>>> uncurl "curl --header \"Authorization:access_token myToken\" https://website.com/id"

requests.get("https://website.com/id",
    headers={
        "Authorization": "access_token myToken"
    },
    cookies={},
)

Answer 6

I'll add a bit hint: it seems what you pass as the key value of a header depends on your authorization type, in my case that was PRIVATE-TOKEN

header = {'PRIVATE-TOKEN': 'my_token'}
response = requests.get(myUrl, headers=header)

Answer 7

A lot of good answers already, but I didn't see this option yet:

If you're using requests , you could also specify a custom authentication class, similar to HTTPBasicAuth . For example:

from requests.auth import AuthBase


class TokenAuth(AuthBase):
    def __init__(self, token, auth_scheme='Bearer'):
        self.token = token
        self.auth_scheme = auth_scheme

    def __call__(self, request):
        request.headers['Authorization'] = f'{self.auth_scheme} {self.token}'
        return request

This could be used as follows (using the custom auth_scheme from the example):

response = requests.get(
    url='https://example.com', 
    auth=TokenAuth(token='abcde', auth_scheme='access_token'),
)

This may look like a more complicated way to set the Request.headers attribute, but it can be advantageous if you want to support multiple types of authentication. Note this allows us to use the auth argument instead of the headers argument.

Answer 8

One of the option used in python to retrieve below:

import requests

token="abcd" < retrieved based>
headers = {'Authorization': "Bearer {}".format(token)}
response = requests.get(
    'https://<url api>',
    headers=headers,
    verify="root ca certificate"
)

print(response.content)

If you get hostname mismatch error then additional SANs need to be configured in the server with the hostnames.

Hope this helps.
