所以我嘗試調用一個僅在文檔中提供令牌 url 的 API。為此，我想使用 python requests 包中的 OAuthlib。當我查看他們的文檔時，他們給出了這個例子：# 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 文檔中，該服務僅提供令牌 url。它給出了這個 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或者這個 HTTP 標頭POST示例：Method: POSTHost: https://login.bol.com/token?grant_type=client_credentialsAccept: application/jsonAuthorization: Basic <credentials><credentials>的串聯在哪里<client_id>:<client_secret>。如何通過此 API 使用請求 OAuthlib？因為API 文檔沒有說明任何授權基礎 url。
