Android：Cloud End Point 的 Firebase 身份验证不工作

Question

我已经按照 link 的要求在服务器上完成了配置。

"/users":
post:
  description: "<Description>"
  operationId: "<OperationID>"
  produces:
  - "application/json"
  responses:
    200:
      description: "user List"
      schema:
        $ref: "#/definitions/echoMessage"
  parameters:
  - description: "Search Criteria"
    in: body
    name: message
    required: true
    schema:
      $ref: "#/definitions/echoMessage"
  security:
    - firebase: []

和

  firebase:
authorizationUrl: ""
flow: "implicit"
type: "oauth2"
x-google-issuer: "https://securetoken.google.com/<Project-ID>"
x-google-jwks_uri: "https://www.googleapis.com/service_accounts/v1/metadata/x509/securetoken@system.gserviceaccount.com"

在通过 JWT 标准后，我开始知道在调用服务时我们必须添加授权 header 和 Bearer 所以我添加了 header 如下，

授权：不记名

我最初尝试使用

String token = FirebaseInstanceId.getInstance().getToken();

但它给出了错误，所以我尝试了，

FirebaseUser firebaseUser = FirebaseAuth.getInstance().getCurrentUser();
    if (firebaseUser != null) {

        firebaseUser.getIdToken(true)
                .addOnSuccessListener(new OnSuccessListener<GetTokenResult>() {
                    @Override
                    public void onSuccess(GetTokenResult getTokenResult) {
                        String token = getTokenResult.getToken();
                        SharedPreferences.Editor editor = mSharedPreferences.edit();
                        editor.putString(Constants.PREFS_FCM_TOKEN, token);
                        editor.apply();
                    }
                });
    }

但即使使用这两种代码，我也会收到错误 401 和 invalid_token

经过这么多天的斗争，我能够解决这个问题。

我按照这个解决了这个问题，

    "/users":
post:
  description: "<Description>"
  operationId: "<OperationID>"
  produces:
  - "application/json"
  responses:
    200:
      description: "user List"
      schema:
        $ref: "#/definitions/echoMessage"
  parameters:
  - description: "Search Criteria"
    in: body
    name: message
    required: true
    schema:
      $ref: "#/definitions/echoMessage"
  security:
    - firebase: []

和

firebase:
authorizationUrl: ""
flow: "implicit"
type: "oauth2"
x-google-issuer: "https://securetoken.google.com/<Project-ID>"
x-google-jwks_uri: "https://www.googleapis.com/service_accounts/v1/metadata/x509/securetoken@system.gserviceaccount.com"
x-google-audiences: "<Project-ID>" //I have added this, this was the main culprit.

如评论中所述，我失踪了

x-google-audiences: ""

在服务器配置中。

关于使用哪个令牌的另一个说明：我们必须使用我在问题中提到的第二种方法，即如下所示，

FirebaseUser firebaseUser = FirebaseAuth.getInstance().getCurrentUser();
    if (firebaseUser != null) { 

        firebaseUser.getIdToken(true)
                .addOnSuccessListener(new OnSuccessListener<GetTokenResult>() { 
                    @Override 
                    public void onSuccess(GetTokenResult getTokenResult) {
                        String token = getTokenResult.getToken();
                        SharedPreferences.Editor editor = mSharedPreferences.edit();
                        editor.putString(Constants.PREFS_FCM_TOKEN, token);
                        editor.apply();
                    } 
                }); 
    }
