How can I get an oauth2 access_token using Python
提问by Johan Vergeer
For a project someone gave me this data that I have used in Postman for testing purposes:
对于一个项目，有人给了我这个我在 Postman 中用于测试目的的数据：
In Postman this works perfectly.
在邮递员中，这非常有效。
Auth URL: https://api.example.com/oauth/access_token
Access Token URL: https://api.example.com/access_token
client ID: abcde
client secret: 12345
Token name: access_token
Grant type: Client Credentials
身份验证 URL：https://api.example.com/oauth/access_token
访问令牌 URL：https
://api.example.com/access_token
客户端 ID：abcde客户端密钥：12345
令牌名称：access_token
授权类型：客户端凭据
All I need is to get back the access token.
我所需要的只是取回访问令牌。
Once, I got the access token I can continue.
有一次，我获得了可以继续的访问令牌。
I have already tried several Python packages and some custom code, but somehow this seemingly simple task starts to create a real headache.
我已经尝试了几个 Python 包和一些自定义代码，但不知何故，这个看似简单的任务开始让人头疼。
One exemple I tried:
我试过的一个例子：
import httplib
import base64
import urllib
import json
def getAuthToken():
CLIENT_ID = "abcde"
CLIENT_SECRET = "12345"
TOKEN_URL = "https://api.example.com/oauth/access_token"
conn = httplib.HTTPSConnection("api.example.com")
url = "/oauth/access_token"
params = {
"grant_type": "client_credentials"
}
client = CLIENT_ID
client_secret = CLIENT_SECRET
authString = base64.encodestring('%s:%s' % (client, client_secret)).replace('\n', '')
requestUrl = url + "?" + urllib.urlencode(params)
headersMap = {
"Content-Type": "application/x-www-form-urlencoded",
"Authorization": "Basic " + authString
}
conn.request("POST", requestUrl, headers=headersMap)
response = conn.getresponse()
if response.status == 200:
data = response.read()
result = json.loads(data)
return result["access_token"]
Then I have got this one:
然后我得到了这个：
import requests
import requests.auth
CLIENT_ID = "abcde"
CLIENT_SECRET = "12345"
TOKEN_URL = "https://api.example.com/oauth/access_token"
REDIRECT_URI = "https://www.getpostman.com/oauth2/callback"
def get_token(code):
client_auth = requests.auth.HTTPBasicAuth(CLIENT_ID, CLIENT_SECRET)
post_data = {"grant_type": "client_credentials",
"code": code,
"redirect_uri": REDIRECT_URI}
response = requests.post(TOKEN_URL,
auth=client_auth,
data=post_data)
token_json = response.json()
return token_json["access_token"]
If this would work, what should I put into the codeparameter
如果这行得通，我应该在code参数中输入什么
I really hope someone can help me out here.
我真的希望有人能在这里帮助我。
Thanks in advance.
提前致谢。

I was finally able to get it done
我终于能够完成它
This is the code I used:
这是我使用的代码：
class ExampleOAuth2Client:
def __init__(self, client_id, client_secret):
self.access_token = None
self.service = OAuth2Service(
name="foo",
client_id=client_id,
client_secret=client_secret,
access_token_url="http://api.example.com/oauth/access_token",
authorize_url="http://api.example.com/oauth/access_token",
base_url="http://api.example.com/",
)
self.get_access_token()
def get_access_token(self):
data = {'code': 'bar',
'grant_type': 'client_credentials',
'redirect_uri': 'http://example.com/'}
session = self.service.get_auth_session(data=data, decoder=json.loads)
self.access_token = session.access_token

Simply (in case of Facebook Authentication):
简单（在 Facebook 身份验证的情况下）：
import requests, json
access_token = requests.get("https://graph.facebook.com/oauth/access_token?grant_type=client_credentials&client_id=your_client_id&client_secret=your_client_secret").json()["access_token"]
Or you can use rauth library.
或者您可以使用rauth 库。
In the docsthere is an interesting example with facebook oAuth2 authentication:
在文档中有一个有趣的示例，其中包含 facebook oAuth2 身份验证：
from rauth import OAuth2Service
facebook = OAuth2Service(
client_id='your_client_id',
client_secret='your_client_secret',
name='facebook',
authorize_url='https://graph.facebook.com/oauth/authorize',
access_token_url='https://graph.facebook.com/oauth/access_token',
base_url='https://graph.facebook.com/')
and after open a session:
打开会话后：
session = facebook.get_auth_session(data={'code': 'foo','redirect_uri': redirect_uri})
in the session json there is your access token
在会话 json 中有您的访问令牌
