对于某个项目,有人向我提供了我在Postman中用于测试目的的数据:
在Postman中,这很有效。
验证网址:https://api.example.com/oauth/access_token
访问令牌网址:https://api.example.com/access_token
客户ID:abcde
客户秘密:12345
令牌名称:access_token
授予类型:客户端凭据
我只需要取回访问令牌。
有一次,我得到了访问令牌,我可以继续。
我已经尝试了几个Python包和一些自定义代码,但不知怎的,这个看似简单的任务开始引起真正的麻烦。
我试过一个例子:
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"]
然后我有了这个:
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"]
如果这样做,我应该将什么放入code
参数
我真的希望有人可以帮助我。
提前致谢。

我终于能够完成它
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
答案 1 :(得分:2)
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"]
或者您可以使用rauth library。
在docs中,facebook oAuth2身份验证有一个有趣的例子:
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/')
并在开会后:
session = facebook.get_auth_session(data={'code': 'foo','redirect_uri': redirect_uri})
在会话json中有你的访问令牌
