如何验证OAuth2 + PCKE流的访问令牌 [英] How to Validate an Access Token for OAuth2 + PCKE flow

问题描述

根据本文档

因此，我如何使用验证令牌API https://developers.onelogin.com/openid-connect/api/validate-session ，因为它支持基本身份验证或 POST ，但不支持 None(PCKE)我找不到与此相关的任何信息.

注意::我尝试使用基本身份验证请求，但没有使用+ client_id，client_secret作为参数，但是无法正常工作.

响应401未经授权

  {错误":"invalid_client"，"error_description":客户端身份验证失败"} 

解决方案

我正在将OIDC与PKCE结合使用，并且设法调用了

从身份验证代码流.

确保未设置 Authorization 标头，而仅在有效负载中设置 client_id .

According to this document https://developers.onelogin.com/openid-connect/guides/auth-flow-pkce

Token Endpoint for PCKE flow is None (not Basic or POST)

So, how can I use the validation token API https://developers.onelogin.com/openid-connect/api/validate-session because it supports Basic authentication or POST but not for None (PCKE) I can't find any information relate to this.

NOTE: I have tried to request with Basic authentication and without + client_id, client_secret as a parameter but not working.

response 401 Unauthorized

{
    "error": "invalid_client",
    "error_description": "client authentication failed"
}

解决方案

I'm using OIDC with PKCE, and I managed to call the https://openid-connect.onelogin.com/oidc/token/introspection endpoint with a token retrieved via the authorization code flow:

$ curl -i -d "token=...&token_type_hint=access_token&client_id=..." https://openid-connect.onelogin.com/oidc/token/introspection

Both the access_token and refresh_token returned from the auth code flow https://developers.onelogin.com/openid-connect/api/authorization-code-grant worked, and the access_token only returned {"active":false} after it expired.

Make sure you are not setting the Authorization header, and only set your client_id in the payload.
