授权在使用OAuth2客户端+资源服务器的网关中不起作用

import requests

# 获取授权码
def get_authorization_code():
    client_id = 'your_client_id'
    redirect_uri = 'http://localhost:8000/callback'
    scope = 'read write'
    auth_url = f'https://auth.example.com/oauth/authorize?client_id={client_id}&redirect_uri={redirect_uri}&response_type=code&scope={scope}'
    print(f'Please navigate to: {auth_url}')
    authorization_code = input('Enter the authorization code: ')
    return authorization_code

# 获取访问令牌
def get_access_token(authorization_code):
    client_id = 'your_client_id'
    client_secret = 'your_client_secret'
    redirect_uri = 'http://localhost:8000/callback'
    token_url = 'https://auth.example.com/oauth/token'
    data = {
        'grant_type': 'authorization_code',
        'code': authorization_code,
        'redirect_uri': redirect_uri,
        'client_id': client_id,
        'client_secret': client_secret
    }
    response = requests.post(token_url, data=data)
    if response.status_code == 200:
        return response.json().get('access_token')
    else:
        raise Exception(f'Failed to get access token: {response.text}')

# 使用访问令牌访问资源
def access_resource(access_token):
    resource_url = 'https://api.example.com/resource'
    headers = {'Authorization': f'Bearer {access_token}'}
    response = requests.get(resource_url, headers=headers)
    if response.status_code == 200:
        return response.json()
    else:
        raise Exception(f'Failed to access resource: {response.text}')
