在 Firebase 云功能中获取用户电话号码

Question

我写过https.onCall firebase cloud function 喜欢

exports.sampleFunction=functions.https.onCall((data,context)=>{
console.log(context.auth.token.phoneNumber+" ***** "+context.auth.token.email+" ***** "+context.auth.token.name);
  return userTransaction.sampleFunction(data,context).then(function(message){
    console.log(message);
  })
});

我正在存储用户的phone number，并且可以使用在客户端获取电话号码

FirebaseAuth auth=FirebaseAuth.getInstance();
        FirebaseUser user=auth.getCurrentUser();
        user.getPhoneNumber();

当我调用这个函数时，我可以看到email 和name 正在打印在firebase cloud functions logs 但phoneNumber 是未定义的。 如何在firebase cloud functions 中通过context 获取user phone number？

Answer 1

简单多了：

exports.myFunction = functions.https.onCall((data, context) => {
    const phone = context.auth.token.phone_number;
})

Answer 2

以下使用admin.auth().getUser(uid) 应该可以工作：

const functions = require('firebase-functions');
const admin = require('firebase-admin');
....

exports.sampleFunction = functions.https.onCall((data,context) => {

  return admin.auth().getUser(context.auth.uid)
    .then(userRecord => {
      const phoneNumber = userRecord.phoneNumber;
      console.log(phoneNumber+" ***** "+context.auth.token.email+"      ***** "+context.auth.token.name);   
      return userTransaction.sampleFunction(data,context)    //Not sure what this is doing, I just chained it with the previous and next then(s). Modify as necessary....
    })
    .then(message => {
      console.log(message);
      return { message: message };
    })

});

请参阅相应的文档here 和here。请注意，getUser() 返回一个承诺。
