python - 错误：flask_oidc：错误：无法获取令牌信息 - 错误：flask_oidc:'token_introspection_uri'
问题描述
我有一个从 Javascript 客户端调用的 Flask rest api。尝试将 Keycloak 集成为身份验证服务器时，我使用烧瓶（使用 flask_oidc）没有成功，所以我首先从 javascript 客户端（有效）进行身份验证，然后使用令牌与烧瓶 rest api 对话。
但是，每当我尝试使用令牌调用休息服务时，我都会收到此错误：
ERROR:flask_oidc:ERROR: Unable to get token info
ERROR:flask_oidc:'token_introspection_uri'

这是我在烧瓶中的代码、设置和 keycloak.json：
OIDC_CLIENT_SECRETS='/app/keycloak.json',
OIDC_RESOURCE_SERVER_ONLY='true',
OIDC_INTROSPECTION_AUTH_METHOD='bearer'
...
{
"web": {
"client_id": "MyClient",

"token_introspection_uri": "http://myservice_auth/auth/realms/myservice/protocol/openid-connect/token/introspect",

"ssl-required": "external",
"resource": "MyClient",
"public-client": true,
"use-resource-role-mappings": true,

}
}
...
oidc = OpenIDConnect(app)
@app.route('/welcome', methods=['GET'])
@oidc.accept_token()
def welcome():
return json.dumps('Welcome %s' % g.oidc_token_info['sub'])
有任何想法吗？
更新 我将 httplib2 降级为 0.11.3，现在错误是：
ERROR:flask_oidc:ERROR: Unable to get token info
ERROR:flask_oidc:[Errno 111] ECONNREFUSED
在定义其余入口点时也添加(require_token=True)到@oidc.accept_token装饰器中，然后在邮递员中，当我尝试使用在 javascript 客户端中获得的相同令牌（成功通过身份验证）对服务执行获取请求时，我收到此错误：
{"error": "invalid_token", "error_description": "Token required but invalid"}
