单独的资源服务器（Django-oauth-toolkit） - 403 禁止错误（如果使用 RESOURCE_SERVER_INTROSPECTION_CREDENTIALS）

Question

我遇到了一个不确定这是否是错误的问题。任何帮助将不胜感激。

一些上下文：

• 授权授予类型是资源所有者密码凭据，其中客户端类型是“机密”。

• 我在资源服务器中使用 csrf_exempt 装饰器和 protected_resource 装饰器作为视图响应函数。

• 使用 Django REST 框架。

• 使用 Django REST Framework v3.12.4 和 Django OAuth Toolkit v1.5.0。

• 我参考了官方文档：https://django-oauth-toolkit.readthedocs.io/en/latest/resource_server.html

• 测试设置类似于使用两个不同端口的参考文章：https://medium.com/@sarit.r/simple-seperate-auth-server-and-resource-server-36a7813ea8aa

Answer 1

对于资源服务器， 将应用程序注册为“基于资源所有者密码” 这将为您提供客户端 ID 和密码。

使用上述客户端 ID 和密码作为用户名和密码，并带有“http basic auth”

# At resource server, to check token
import requests
from requests.auth import HTTPBasicAuth

introspect_url = '<auth-server-host-here>/o/introspect/'
introspect_data = {'token': access_token_here}
introspect_response = requests.post(introspect_url, data=introspect_data, auth=HTTPBasicAuth(resource_server_client_id_here, resource_server_client_secret_here))
