django - django 3 上带有 keycloak 的 Mozilla-django-oidc

问题描述

我正在尝试使用mozilla-django-oidc (1.2.4) 将 Django (3.2) 与 Keycloak (12.0.2) 连接起来。

单击“登录”按钮（oidc_authentication_init根据文档使用视图）时，我将重定向到 keycloak，但是在成功登录后出现此错误：

Exception Type: HTTPError at /oidc/callback/
Exception Value: 404 Client Error: Not Found for url: http://localhost:8080/auth/realms/mycorp/protocol/openid-connect/token

django设置的相关设置有：

settings.py

INSTALLED_APPS = [
    ...,
    'mozilla_django_oidc',
]
AUTHENTICATION_BACKENDS = (
    'django.contrib.auth.backends.ModelBackend',
    'mozilla_django_oidc.auth.OIDCAuthenticationBackend',
),

OIDC_AUTH_URI = 'http://localhost:8080/auth/realms/mycorp'
OIDC_CALLBACK_PUBLIC_URI = 'http://localhost'

LOGIN_REDIRECT_URL = OIDC_CALLBACK_PUBLIC_URI
LOGOUT_REDIRECT_URL = OIDC_AUTH_URI + '/protocol/openid-connect/logout?redirect_uri=' + OIDC_CALLBACK_PUBLIC_URI

OIDC_RP_CLIENT_ID = 'django'
OIDC_RP_CLIENT_SECRET = os.environ.get("OIDC_CLIENT_SECRET")
OIDC_RP_SCOPES = 'openid email profile'

# Keycloak-specific (as per http://KEYCLOAK_SERVER/auth/realms/REALM/.well-known/openid-configuration)
OIDC_OP_AUTHORIZATION_ENDPOINT = OIDC_AUTH_URI + '/protocol/openid-connect/auth'
OIDC_OP_TOKEN_ENDPOINT = OIDC_AUTH_URI + '/protocol/openid-connect/token'
OIDC_OP_USER_ENDPOINT = OIDC_AUTH_URI + '/protocol/openid-connect/userinfo'
OIDC_OP_JWKS_ENDPOINT = OIDC_AUTH_URI + '/protocol/openid-connect/certs'

urls.py

urlpatterns = [
    ...,
    path('oidc/', include('mozilla_django_oidc.urls')),
]

和详细的错误：

HTTPError at /oidc/callback/
404 Client Error: Not Found for url: http://localhost:8080/auth/realms/mycorp/protocol/openid-connect/token
Request Method: GET

显然一切都按照文档中的说明进行了配置，但我看不出它失败的原因......

标签： djangokeycloakopenid-connect

解决方案

404 对我来说还不够清楚，直到我意识到测试是在 docker-compose 上运行的，所以对 localhost 的访问与主机不同。

在主机网络模式下运行或通过其域名/主机 IP 到达 keycloak（请参阅下面172.20.0.1哪个是主机的 docker 网络 IP）修复了它：

OIDC_AUTH_URI=http://172.20.0.1:8080/auth/realms/mycorp
OIDC_AUTHENTICATION_CALLBACK_URL=http://localhost/openid/callback
OIDC_CALLBACK_PUBLIC_URI=http://localhost/
