Firebase LoginWithCustomToken抛出错误

Question

我正在使用nodejs中的jsonwebtoken创建firebase自定义令牌，一旦创建了令牌并传递给firebase.auth().signInWithCustomToken(令牌)，返回错误消息如下

自定义令牌格式不正确。请查看文档.

Private_key：“--开始私钥

将private_key存储在fb-私有机密. the文件中

Note--以及\n我从防火墙获得的ServiceAccountKey.json文件。

**Sample code:-**

const jwt = require("jsonwebtoken");
const fb_private_key = fs.readFileSync('./fb-private-secret.key').toString().replace(/\\n/gm, '\n');

in Nodejs express :-

const token = jwt.sign({
  "iss": "https://securetoken.google.com/****",
  "sub": user.uid,
  "aud": "banded-totality-****",
  "iat": new Date().getTime(),
  "exp": new Date().getTime()+(60*60*24*5)*1000,
  "uid":user.uid
},fb_private_key,{header:{kid:'#####' }, algorithm:'RS256' });

In Reactjs Front-End:-
//token which i get from the server.
const {user} = await firebase.auth().signInWithCustomToken(token);
At the above line (signInWithCustomToken) error comes says
the custom token format is incorrect. please check the documentation.

任何帮助都将不胜感激。

谢谢

若要使用自定义令牌登录，必须使用正确的属性生成。具体地说：

alg: "RS256"
aud: "https://identitytoolkit.googleapis.com/google.identity.identitytoolkit.v1.IdentityToolkit"

更新

Admin解决方案：

const  admin = require('firebase-admin');
const credentials = require('./credentials.json');

admin.initializeApp({
   credential: admin.credential.cert(credentials)
});

// example of claims
const additionalClaims = {
    premium: true
}

admin.auth().createCustomToken("user_id_goes_here", additionalClaims)
.then((customToken )=> {
    console.log(customToken);
})
.catch(console.error);
