Firebase Auth-使用GoogleAuthProvider重新验证用户时遇到困难

Question

根据文档，我需要重新验证用户谁试图删除他们的帐户，但没有登录一段时间。下面是文档（非常底部）：

文件编制

如果执行其中一个操作，而用户登录时间太长，则操作失败并出现错误。当发生这种情况时，通过从用户获取新的登录凭据并将凭据传递给reauthenticateWithCredential来重新验证用户

var user = firebase.auth().currentUser;
var credential;

// Prompt the user to re-provide their sign-in credentials

user.reauthenticateAndRetrieveDataWithCredential(credential).then(function() {
  // User re-authenticated.
})

var credential = firebase.auth.EmailAuthProvider.credential(email, password);

var user = firebase.auth().currentUser;
let credential = firebase.auth.GoogleAuthProvider.credential(firebase.auth().currentUser.email);

user.reauthenticateAndRetrieveDataWithCredential(credential).then(() => {
  // User re-authenticated.
});

请帮忙。

您的问题是，您试图检索谷歌凭据使用电子邮件地址，这是不可能的。

let credential = firebase.auth.GoogleAuthProvider.credential(firebase.auth().currentUser.email);

根据文件，

credential(idToken，accessToken)返回firebase.auth.oAuthCredential

var credential = firebase.auth.GoogleAuthProvider.credential(id_token);

var credential = firebase.auth.GoogleAuthProvider.credential(null,access_token);

firebase.auth().currentUser.reauthenticateWithPopup(
    new firebase.auth.GoogleAuthProvider()).then(function(userCredential) {
        // You can now delete the user:
        return firebase.auth().currentUser.delete();  
    }).catch(function(error) {
        // Credential mismatch or some other error.  
    }
);
