英文:
Find Signed up User from redirect of AWS Cognito Hosted UI
问题
我想知道哪个用户在我的Cognito托管UI上注册了。
根据AWS文档的配置，一切都正常。
打开UI后，它能正常工作。
但是，一旦重定向到我的网站，它会附加一个类似这样的UUID代码：
https://example.com/signup?code=140ac1a7-aaaa-bbbb-cccc-180bcb7c55f0
但似乎提供的代码与刚刚创建的用户无关。
我漏掉了什么地方？
附加信息：我正在使用Java后端开发，因此无法使用JS SDK。
我尝试将response_type更改为token而不是code，但然后托管UI会将我重定向到：
https://example.com/signup?#error_description=unauthorized_client&error=invalid_request
英文:
I want to know which user has signed up on my Cognito hosted UI.
I configured everything accordingly to the AWS documentation.
When opened, the UI works just fine.
As soon as it comes to the redirect to my website it appends a UUID code like this:
https://example.com/signup?code=140ac1a7-aaaa-bbbb-cccc-180bcb7c55f0
But it seems that the given code has nothing in common with the user that was just created.
Where am I missing something?
Additional info: I'm working on a java backend, so I cannot use the JS SDK
I tried to change the response_type to token instead of code but then the hosted UI redirects me to:
https://example.com/signup?#error_description=unauthorized_client&error=invalid_request

UUID是访问代码。 使用它，您可以获取访问令牌，该令牌可以提供用户信息。
文档可以在此处找到：
https://docs.aws.amazon.com/cognito/latest/developerguide/token-endpoint.html
而请求如下所示：
POST https://your-pool.auth.your-region.amazoncognito.com/oauth2/token
Content-Type: application/x-www-form-urlencoded
grant_type=authorization_code&
client_id=your-code&
code=the-access-code&
redirect_uri=your-redirect
英文:
The UUID is the access code. With it u can get the access token which can provide you with the user information.
The documentation can be found here:
https://docs.aws.amazon.com/cognito/latest/developerguide/token-endpoint.html
And the request looks like this:
POST https://your-pool.auth.your-region.amazoncognito.com/oauth2/token
Content-Type: application/x-www-form-urlencoded
grant_type=authorization_code&
client_id=your-code&
code=the-access-code&
redirect_uri=your-redirect
