[ANDROID-BUG] Getting firebase token?

[IvRRimum]

How can i get the auth token from:

 57     this.ngZone.run(() => {
 58       firebase.getCurrentUser().then((data) => {
 59         this.currentUserId.next(data.uid);
 60       });
 61     });

I need the token, so i can send it to my backend and upload resized photos to firebase. Is there a better way to do this?

[xerotolerant]

You can access it using data.refreshToken.

this.ngZone.run(() => {
 58       firebase.getCurrentUser().then((data) => {
 59         this.currentUserId.next(data.uid);
               this.token = data.refreshToken;
 60       });
 61     });

@xerotolerant That is exactly what i need, but:

 app/views/header/header.component.ts(60,26): error TS2339: Property 'refreshToken' does not exist on type 'User'.

Versions:

 1 {
  2   "name": "nativescript-plugin-firebase",
  3   "version": "3.6.3",
  4   "description": "Fire. Base. Firebase!",

[IvRRimum]

Okey, this is a bit weird. But the property refreshToken is there only in IOS. Not android.

There is this method in user.

getToken()

but when called:

[IvRRimum]

@EddyVerbruggen Maybe you have ideas?

[xerotolerant]

What happens if you stringify the user object?
console.log(JSON.stringify(user));

can you see the token under another name or something?

[IvRRimum]

@xerotolerant The getToken() methid is inside the getCurrentUser method inside the plugin. I will try console stringify it.

In this context. user has property getToken().

but whats weird:

Comments the token out, this is a method called, when a login has been successful.

[EddyVerbruggen]

I'll take a look..

[EddyVerbruggen]

I think it's best to add a new method (something like) getAuthToken with an optional forceRefresh property which gets a Firebase authentication token. The reason is that it's an async method on both platforms so it would delay the login promise. The iOS refreshToken will remain but (as documented by Firebase) that should only be used for "advanced scenario's".

Sounds good?

[EddyVerbruggen]

The problem was getToken is nowgetToken(forceRefresh:boolean), so that explains the error (the signature is incorrect).

The GitHub version now has a new getAuthToken:

firebase.getAuthToken({
  forceRefresh: false
}).then(
  function (token) {
    console.log("Auth token retrieved: " + token);
  },
  function (errorMessage) {
    console.log("Auth token retrieval error: " + errorMessage);
  }
);

Please give it a spin and I'll soon publish to npm as well.

[EddyVerbruggen]

Available in 3.6.4.

[IvRRimum]

firebase.getAuthToken is not a function

var firebase = require("nativescript-plugin-firebase");

 67     firebase.getAuthToken({
 68       forceRefresh: false
 69     }).then(
 70       function (token) {
 71         console.log("Auth token retrieved: " + token);
 72       },
 73       function (errorMessage) {
 74         console.log("Auth token retrieval error: " + errorMessage);
 75       }
 76     );

  1 {
  2   "_args": [
  3     [
  4       {
  5         "raw": "nativescript-plugin-firebase@3.6.4",
  6         "scope": null,
  7         "escapedName": "nativescript-plugin-firebase",
  8         "name": "nativescript-plugin-firebase",
  9         "rawSpec": "3.6.4",
 10         "spec": "3.6.4",
 11         "type": "version"
 12       },

Still doesn't work on android.

[IvRRimum]

Tryed removing the plugin and install again. Delete the platform folder. and reinstall the app. Still the same error. When i open node_modules/firebase.d.ts i can see the getAuthMethod()

[IvRRimum]

the firebase.android.js file doesnt contain the getAuthToken method

[IvRRimum]

I am calling console.log(user.getToken(false)); in firebase.android.js in the get getCurrentUser method.
I am getting this: JS: com.google.android.gms.tasks.zzh@3f76ac84 This is not the token...

[EddyVerbruggen]

All ok now?

[IvRRimum]

Looks like it :)

I'm using the Facebook login on an Android emulator. When I call firebase.getAuthToken() it always returns the uid as the token instead of a JWT. Is that how it's supposed to work? How can I get a JWT to authenticate the user in my own web services?
