android - 没有 verificationProof、sessionInfo 或临时证明，无法创建 PhoneAuthCredential。当我删除 firebase 用户时

Question

我正在使用 firebase 和 android studio。我在尝试删除用户时遇到了一个问题。访问我的应用程序的唯一方法是电话号码身份验证。

我已经知道当我删除用户时，必须重新验证。 所以我引用了 firebase 文档并尝试了它们。 AuthCredential.getCredential() 方法需要多个值，尽管我只有 PhoneNumber 和 UID。 这就是我所知道的

这是代码

AuthCredential credential = PhoneAuthProvider
                        .getCredential(user.getUid(), null);

                user.reauthenticate(credential)
                .addOnCompleteListener(new OnCompleteListener<Void>() {

                    //재인증 성공시
                    @Override
                    public void onComplete(@NonNull Task<Void> task) {

                        //삭제
                        user.delete()
                        .addOnCompleteListener(new OnCompleteListener<Void>() {
                            @Override
                            public void onComplete(@NonNull Task<Void> task) {
                                if (task.isSuccessful()) {
                                    Log.d("result", "User account deleted.");
                                }else{
                                    Log.d("", task.getException().getStackTrace().toString());
                                }
                            }
                        });
                    }
                });

这是异常(exception) :

java.lang.IllegalArgumentException: Cannot create PhoneAuthCredential without either verificationProof, sessionInfo, ortemprary proof.

显然，您也可以使用云功能删除用户，而无需重新验证用户，只需提供 uid。方法如下

exports.deleteUser = functions.https.onRequest((req, res) => {
  if (req.body.uid === undefined) {
    res.status(400).send('No user id defined');
  } else {
    var userId = req.body.uid;

    admin.auth().deleteUser(userId)
        .then(function() {
            console.log("Successfully deleted user");    
        })
        .catch(function(error) {
            console.log("Error deleting user: ", error);
        });

    res.status(200).end();
}
});
