Answer 1

catch error with callback:

使用回调捕获错误：

firebase.auth().signOut().then(function() {
  // Sign-out successful.
}, function(error) {
  // An error happened.
});

or with .catch as Adam mentioned.

或使用亚当提到的 .catch 。

firebase.auth().signOut()
  .then(function() {
    // Sign-out successful.
  })
  .catch(function(error) {
    // An error happened
  });

Or with await and try...catchif inside async function

或者使用 await 和try...catchif 在异步函数中

try {
  await firebase.auth().signOut();
  // signed out
} catch (e){
 // an error
}

thanks AndréKoolfor directions :-)

感谢安德烈库尔的指导:-)

Answer 2

Lukas Liesis has the correct firebase signOut() method but to resolve a rejected promise, I used .catch()instead.

Lukas Liesis 有正确的 firebase signOut() 方法，但为了解决被拒绝的承诺，我.catch()改用了。

firebase.auth().signOut()
  .then(function() {
    // Sign-out successful.
  })
  .catch(function(error) {
    // An error happened
  });

This statement logouts the user.

此语句使用户注销。

    FirebaseAuth.getInstance().signOut();
