Istio 策略不对 JWT 进行身份验证

Question

我已经实施了一个 istio 政策，这样用户将需要一个 JWT 令牌来访问我的后端和 admin-backend 服务。但是，它并没有让我通过有效的令牌。我在 minikube 上运行 istio-demo，除了为 auth0 配置出口外，我没有对我的部署做任何事情。然后，当我去应用我的政策时，我无法再根据我的请求访问这些服务。

rbac-policy.yaml

apiVersion: "authentication.istio.io/v1alpha1"
kind: "Policy"
metadata:
  name: rbac
  namespace: default
spec:
  targets:
    - name: backend
    - name: admin-backend
  peers:
    - mtls: {}
  origins:
    - jwt:
        issuer: "https://jor2.eu.auth0.com/"
        jwksUri: "https://jor2.eu.auth0.com/.well-known/jwks.json"
  principalBinding: USE_ORIGIN

这是在我的 get 和 post 请求中传递的内容 headers（HEADERS 的值）：

{
  "Authorization": "Bearer eyJ0eXAiOiJKV1QiLCJhbGciOiJSUzI1NiIsImtpZCI6Ik5VVkdPREl4UVRoQlFrWTJOakV4UWpnek1FSkVNalZCUVRjM1FUaEJOVFk0UVRZM016aEVNQSJ9.eyJpc3MiOiJodHRwczovL2pvcjIuZXUuYXV0aDAuY29tLyIsInN1YiI6IlRsdmg5OFl4Wkc2anFpNmRVclhlN2RIejVwZzFiaHR1QGNsaWVudHMiLCJhdWQiOiJodHRwczovL3JiYS5jb20vYWRtaW4iLCJpYXQiOjE1NTI1NTU0NjUsImV4cCI6MTU1MjY0MTg2NSwiYXpwIjoiVGx2aDk4WXhaRzZqcWk2ZFVyWGU3ZEh6NXBnMWJodHUiLCJzY29wZSI6IkFkbWluIiwiZ3R5IjoiY2xpZW50LWNyZWRlbnRpYWxzIn0.grrHHrS_Ey63Tmo1KL9gUmelouYaSj0rPlv04tpJxBeVct-KRA30I1ieVgncmojRBXcdgvfpWKjeGLbb2Q7X6QwkdT0LyO3jmOBgabcTIsnnbCEg4gywc7WrN5_H_bWNiToIsouagJqiAOQ35wrVa9SVK_InR0QVEnV3yvuug042yMiMmFriG6qN2J8HPgXCE440hpSXBIIKuoBqmNZGSjZV3YvQXaLmigCNl2_PUXb52urrQqHEh06dMIT2FFfD5Cdc1RGrRT2o4krMWF2mJMOWXK1sgEOv4FfsOrdkPka24MuGViED514EoJ9a2n2QEK10zxDtv42opYT9Wjmubg"
}

功能正确 header（应该工作）但不显示任何响应。

@app.route("/view_patients/", methods=['GET', 'POST'])
def view_patients():
    global HEADERS
    patients = invoke_backend(page_name="view_patients", headers=HEADERS)
    return render_template(
        'view_patients.html',
        patients=patients
    )

测试以确保令牌在无效的 jwt 上失败：

@app.route("/test/view_patients/", methods=['GET', 'POST'])
def test_view_patients_invalid_jwt():
    jwt = "1nv4l1DJwT"
    header = {
        'Authorization': "Bearer " + jwt
    }
    patients = invoke_backend(page_name="view_patients", headers=header)
    return render_template(
        'view_patients.html',
        patients=patients
    )

几天前我想通了，但忘了 post 答案。我需要从配置中删除 mtls。

apiVersion: authentication.istio.io/v1alpha1
kind: Policy
metadata:
  name: auth-policy
spec:
  targets:
    - name: backend
    - name: admin-backend
  origins:
    - jwt:
        issuer: "https://jor2.eu.auth0.com/"
        jwksUri: "https://jor2.eu.auth0.com/.well-known/jwks.json"
  principalBinding: USE_ORIGIN
