Oauth 2.0 LinkedIn API获取访问令牌失败

我们正试图基于：

https://docs.microsoft.com/en-us/linkedin/shared/authentication/authorization-code-flow?context=linkedin/context

我们将应用程序设置的重定向url作为公司的主页（

https://www.{site}.com

），我们可以从重定向URL获取身份验证代码。然而，当交换访问令牌时，它给出了下面的401错误：

b'{"error":"invalid_request","error_description":"Unable to retrieve 
access token: authorization code not found"}' 

奇怪的是，如果我们将重定向url切换到另一个站点，比如

https://www.example.com

在API控制台中。下面是我们使用的Py3代码：

from requests_oauthlib import OAuth2Session
from requests_oauthlib.compliance_fixes import linkedin_compliance_fix

# Credentials and redirect uri you get from registering a new application
client_id = 'client_id'
client_secret = 'client_secret'
redirect_url = 'redirect_url'


# OAuth endpoints given in the LinkedIn API documentation (check for updates)
authorization_base_url = 'https://www.linkedin.com/oauth/v2/authorization'
token_url = 'https://www.linkedin.com/oauth/v2/accessToken'

# Authorized Redirect URL (from LinkedIn config)
o2_session = OAuth2Session(client_id=client_id, redirect_uri=redirect_url, scope=['rw_ads', 'r_ads_reporting'])
linkedin = linkedin_compliance_fix(o2_session)

# Redirect user to LinkedIn for authorization
authorization_url, state = linkedin.authorization_url(authorization_base_url)

print('Please go here and authorize,', authorization_url)

# Get the authorization verifier code from the callback url
redirect_response = input('Paste the full redirect URL here:')
linkedin.fetch_token(token_url, include_client_id=client_id, client_secret=client_secret, authorization_response=redirect_response)
token = linkedin.access_token

理解身份验证代码的生命周期很短，因此在代码发回URL后的几秒钟内尝试重定向URL。任何人都能想到任何原因会导致这种奇怪的行为，不同的重定向URL
