在ngx-admin中设置令牌以连接到Firebase

Question

I am trying to configure my ngx-admin to connect to Firebase using REST API. Most of the posts on Stack Overflow instruct to rewrite the authentication code using Firebase's SDK. This is not what I want. Instead, ngx-admin is already designed to use REST API for authentication, which is also supported by Firebase. I therefore decided to take this approach to use the ngx-admin codebase as much as possible.

My setting under NB_CORE_PROVIDERS in core.module.ts is as follows (showing only the login setting for simplicity):

providers: {
      email: {
        service: NbEmailPassAuthProvider,
        config: {
          baseEndpoint: 'https://www.googleapis.com/identitytoolkit/v3/relyingparty',
          delay: 3000,
          login: {
            rememberMe: true,
            endpoint: '/verifyPassword?key='+environment.firebase.apiKey,
          },
          // ...
          token: {
            // How to set this properly for Firebase?
          }, 
        },
      },
    },

My difficulty is in how to set the token properly for Firebase. The tutorial at https://akveo.github.io/nebular/#/docs/auth/getting-user-token says that

By default Nebular expects that your token is located under the data.token keys of the JSON response

This translates to the following default setting in @nebular/auth/providers/email-pass-auth.provider.ts :

token: {
  key: 'data.token',
  getter: (module: string, res: HttpResponse<Object>) => getDeepFromObject(res.body,
        this.getConfigValue('token.key')),
},

The tutorial then gives an example which assumes that:

our API returns a token as just {token: 'some-jwt-token'} not wrapping your response in the data property

and this translates to:

token: {
  key: 'token', // this parameter tells Nebular where to look for the token
},

First I tried skipping the token setting (which means I use the default, which is key: 'data.token' . While I could got a 200 status code (which means I successfully connected to Firebase), I got the following error: NbEmailPassAuthProvider: Token is not provided under 'data.token' key with getter 'function (module, res) { return Object(__WEBPACK_IMPORTED_MODULE_9__helpers__["getDeepFromObject"])(res.body, _this.getConfigValue('token.key')); }', check your auth configuration.

Then I tried key: 'token' which gave me a similar error.

Upon consulting the Firebase documentation at https://firebase.google.com/docs/reference/rest/auth/#section-sign-in-email-password , I found that the response payload of Firebase consists of six properties: kind, idToken, email, refreshToken, expliresIn, localId, registered . I then tried key: 'idToken' and this time it worked. I could successfully logged into Firebase. Trying the same for signup also successfully signed me up in Firebase, as I could verify from the Firebase console.

However, this only gets one of the six properties returned. I tried key: 'data' instead but it gave me a similar error as above. How can I configure the token key properly so that I can store all the six properties of the token?

Or, should I not attempt to get the other properties but should stick to idToken instead? In that case, how could I specify different tokens when the API returns something else in the payload (eg when requesting email verification Firebase only returns kind and email in the payload).

Thank you very much.

Answer 1

try with this:

  key: 'idToken'
},

it is working for me, with a successful authResult. Good Coding;
