【问题标题】：OAuth1 authentication using Requests-OAuthlib failing使用 Requests-OAuthlib 的 OAuth1 身份验证失败

【问题描述】：

我正在尝试使用 Requests-OAuthlib 对 OAuth1 进行身份验证，但它失败了。我正在从以下网站获取帮助：

https://requests-oauthlib.readthedocs.io...#oauth-1-0

>> client_key = 'xxxx'
>> client_secret = 'xxxx'
>> callback_uri = 'https://127.0.0.1/callback'
>> request_token_url='https://rest.immobilienscout24.de/restapi/security/oauth/request_token',
>> access_token_url='https://rest.immobilienscout24.de/restapi/security/oauth/access_token',
>> authorize_url='https://rest.immobilienscout24.de/restapi/security/oauth/confirm_access',
>> oauth_session = OAuth1Session(client_key,client_secret=client_secret, callback_uri=callback_uri)
>> oauth_session.fetch_request_token(request_token_url)

请教如何解决这个问题

【解决方案1】：

据我了解，此错误是由以下原因引起的：

normalized_uri = signature.base_string_uri(uri, headers.get('Host', None))

在这段代码中，uri 是None，所以它会在标题中使用Host：

headers.get('Host', None)

但是，标头中的 Host 将不包含架构，Host 看起来像：

www.google.com

Host 中没有 https://。您可能需要向库报告错误。

还有一个库（我是作者），和requests-oauthlib共享一个熟悉的API，可以查看：https://docs.authlib.org/en/latest/client/oauth1.html

from authlib.integrations.requests_client import OAuth1Session
