如何使用带有授权类型“客户端凭据”的请求 OAuthlib？

Question

所以我尝试调用一个仅在文档中提供令牌 url 的 API。为此，我想使用 python requests 包中的 OAuthlib。当我查看他们的文档时，他们给出了这个例子：# Credentials you get from registering a new applicationclient_id = '<the id you get from github>'client_secret = '<the secret you get from github>'# OAuth endpoints given in the GitHub API documentationauthorization_base_url = 'https://github.com/login/oauth/authorize'token_url = 'https://github.com/login/oauth/access_token'from requests_oauthlib import OAuth2Sessiongithub = OAuth2Session(client_id)# Redirect user to GitHub for authorizationauthorization_url, state = github.authorization_url(authorization_base_url)print ('Please go here and authorize,', authorization_url)# Get the authorization verifier code from the callback urlredirect_response = input('Paste the full redirect URL here:')# Fetch the access tokengithub.fetch_token(token_url, client_secret=client_secret,        authorization_response=redirect_response)# Fetch a protected resource, i.e. user profiler = github.get('https://api.github.com/user')print (r.content)但在 API 文档中，该服务仅提供令牌 url。它给出了这个 Http BodyPOST示例：Method: POSTHost: https://login.bol.com/tokenContent-Type: application/x-www-form-urlencodedAccept: application/jsonBody: client_id=oRNWbHFXtAECmhnZmEndcjLIaSKbRMVE&client_secret= MaQHPOnmYkPZNgeRziPnQyyOJYytUbcFBVJBvbMKoDdpPqaZbaOiLUTWzPAkpPsZFZbJHrcoltdgpZolyNcgvvBaKcmkqFjucFzXhDONTsPAtHHyccQlLUZpkOuywMiOycDWcCySFsgpDiyGnCWCZJkNTtVdPxbSUTWVIFQiUxaPDYDXRQAVVTbSVZArAZkaLDLOoOvPzxSdhnkkJWzlQDkqsXNKfAIgAldrmyfROSyCGMCfvzdQdUQEaYZTPEoA&grant_type=client_credentials或者这个 HTTP 标头POST示例：Method: POSTHost: https://login.bol.com/token?grant_type=client_credentialsAccept: application/jsonAuthorization: Basic <credentials><credentials>的串联在哪里<client_id>:<client_secret>。如何通过此 API 使用请求 OAuthlib？因为API 文档没有说明任何授权基础 url。

Answer 1

我认为你可以提供<client_id>:<client_secret>这样的：

from oauthlib.oauth2 import BackendApplicationClient

client = BackendApplicationClient(client_id=client_id)

oauth = OAuth2Session(client=client)

token = oauth.fetch_token(token_url='https://provider.com/oauth2/token', client_id=client_id,

        client_secret=client_secret)

看到这个
