Google ESP可选身份验证

Question

我正在使用Google ESP，并且在端点上我具有Auth0的授权，如下所示：

securityDefinitions:
    auth0_jwk:
        authorizationUrl: "AUTH_URL"
        flow: "implicit"
        type: "oauth2"
        x-google-issuer: "AUTHO_URL"
        x-google-jwks_uri: "AUTH0_JWKS_URL"
        x-google-audiences: "AUTH0_AUDIENCE"
paths:
  /pluginviewservice/v1:
    post:
      summary: Submits a page to be analysed with auth.
      operationId: pluginviewservicev1
      x-google-backend:
        address: APP_ENGINE_URL
        path_translation: CONSTANT_ADDRESS
      responses:
        '200':
          description: A successful response
          schema:
            type: string
      x-security:
        - {}
        - auth0_jwk:
            audiences:
              - "AUTH0_AUDIENCE"

但是我想要的是，当auth0访问令牌可用时，它将填充“ X-Endpoint-API-UserInfo”，而当它不存在时，它将使其完全通过。端点被设计为授权和未授权用户均可访问。我已经尝试过添加一个空白的“ x-security”，如上所述，但这似乎不起作用。
