Python - 缺少“client_id”。怎么解决？

Question

我一直在使用 LinkedIn api (OAuth 2)，并找到了一个示例来帮助测试它。我已按照教程进行操作，但由于某种原因，当我提供完整的重定向 URL（按照代码中的要求）时，出现错误：(invalid_request) A required parameter "client_id" is missing。我不确定我做错了什么，但如果有人有任何想法，我感谢您的反馈。

在寻找解决方案时，我发现另一个人正在为此苦苦挣扎："client_id" is missing when authenticate with LinkedIn

这是示例中的代码：

Linkedin.py

from requests_oauthlib import OAuth2Session
from requests_oauthlib.compliance_fixes import linkedin_compliance_fix

# Credentials you get from registering a new application
client_id = SECRET
client_secret = SECRET

# OAuth endpoints given in the LinkedIn API documentation
authorization_base_url = 'https://www.linkedin.com/uas/oauth2/authorization'
token_url = 'https://www.linkedin.com/uas/oauth2/accessToken'

linkedin = OAuth2Session(client_id, redirect_uri='http://localhost:8000')
linkedin = linkedin_compliance_fix(linkedin)

# 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:')

# Fetch the access token
linkedin.fetch_token(token_url, client_secret=client_secret,authorization_response=redirect_response)

# Fetch a protected resource, i.e. user profile
r = linkedin.get('https://api.linkedin.com/v1/people/~')
print (r.content)

附加说明：我使用的教程没有日期。我只能假设 API 教程中使用的链接是正确且最新的。

Answer 1

这个有点旧，但我想我会从 oauth requests 文档网站分享一些需要对 LinkedIn 示例进行的额外更改。

随着更新的链接，LinkedIn 似乎在用验证器代码交换令牌时期望请求正文中的client_id。我不确定它在何处或何时被遗忘，但在深入了解 oauth-request 源代码后，我发现fetch 方法有一个参数，它强制将client_id 包含在请求正文中（@987654324 @) 将它添加到 fetch 方法应该可以使示例工作。

linkedin.fetch_token(token_url, client_secret=client_secret,
                     authorization_response=redirect_response,
                     include_client_id=True)

Answer 2

问题在于URLs，我写了一个类似的程序，它对我来说非常有效：

from requests_oauthlib import OAuth2Session
from requests_oauthlib.compliance_fixes import linkedin_compliance_fix


# Credentials you get from registering a new application
client_id = '<the client id you get from linkedin>'
client_secret = '<the client secret you get from linkedin>'
redirect_url = '<authorized redirect URL from LinkedIn config>'

# OAuth endpoints given in the LinkedIn API documentation (you can check for the latest 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 configuration)
linkedin = OAuth2Session(client_id, redirect_uri=redirect_url)
linkedin = linkedin_compliance_fix(linkedin)

# 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:')

# Fetch the access token
linkedin.fetch_token(token_url, client_secret=client_secret,
                     authorization_response=redirect_response)

# Fetch a protected resource, i.e. user profile
r = linkedin.get('https://api.linkedin.com/v1/people/~')
print(r.content)

希望对你有帮助！

虽然这可能不是您的问题的原因，但您使用的是旧版本的 LinkedIn 身份验证 URL。从 LinkedIn 的 OAuth 文档 (https://docs.microsoft.com/en-us/linkedin/shared/authentication/authorization-code-flow?context=linkedin/consumer/context) 你的 authorzation_base_url 应该是

https://www.linkedin.com/oauth/v2/authorization
