Firebase - Facebook Auth

Question

我正在努力让我的简单Facebook登录工作。我只是试图在网站上学习这个例子，但是我遇到了这个错误：

Uncaught: L {code: "auth/argument-error", message: "signInWithPopup failed: First argument "authProvider" must be a valid Auth provider."}

我想做的就是：

export const createUserWithFacebook = () => {
  let provider = firebase.auth.FacebookAuthProvider();
  firebaseApp.auth().signInWithPopup(provider).then(function(result) {
    // This gives you a Facebook Access Token. You can use it to access the Facebook API.
    var token = result.credential.accessToken;
    // The signed-in user info.
    var user = result.user;
    // firebaseApp.auth().signInWithRedirect(provider);
  }).catch(function(error) {
    // Handle Errors here.
    var errorCode = error.code;
    var errorMessage = error.message;
    // The email of the user's account used.
    var email = error.email;
    // The firebase.auth.AuthCredential type that was used.
    var credential = error.credential;
  });
}

有人能指出我在这里做错了什么吗？谢谢你的帮忙!

在您的消防实例中，Facebook provider对象应该是：

let provider = new firebase.auth.FacebookAuthProvider();

这个new将为新实例使用firebase自己的构造函数。

而不是：

let provider = firebase.auth.FacebookAuthProvider();
