我想将 email 验证发送到 firebase 中未用于注册帐户的另一个帐户

Question

我的注册活动中有 3 个字段。

用户名 Email 和密码。

因此，将使用将显示在身份验证页面上的用户名创建帐户，但我想将 email 发送到 Email 字段，但如何将其发送到编辑文本中指定的 email 字段。 这是我使用的代码。

所以我想要名为 email 的字段来获得验证 email 有人可以提供解决方案吗？

Answer 1

在 firestore 中创建一个文档，文档名称为username和字段email 。

简介

• fatalcoder524 //用户名
  1. email: test@test.com //电子邮件验证
  2. dob: 12/12/12 //其他细节

首先检查用户名是否存在于firestore中。

• 如果存在，请使用 firestore 中的 email 和用户密码进行验证。
• 如果没有，请让用户注册。

示例代码：（注册）

String email; //user input
String username; //user input
String password; //user input

Map<String, Object> user = new HashMap<>();
user.put("email", email);   // data to add to firestore

db.collection("profiles").document(username) //username is set as firestore document name, profiles is the collection name
        .set(user)  //Store the email in above document.
        .addOnSuccessListener(new OnSuccessListener<Void>() {
            @Override
            public void onSuccess(Void aVoid) // If data is added successfully
            {
                mAuth.createUserWithEmailAndPassword(email, password) // create account
        .addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
            @Override
            public void onComplete(@NonNull Task<AuthResult> task) {
                if (task.isSuccessful()) {
                    // Sign in success, update UI with the signed-in user's information
                    Log.d(TAG, "createUserWithEmail:success");
                } else {
                    // If sign in fails, display a message to the user.
                    Log.w(TAG, "createUserWithEmail:failure", task.getException());
                }
            }
        });

            }
        });

示例代码：（登录）

String username;  //get username from user
String password; //get password from user
DocumentReference docRef = db.collection("profiles").document(username); //get doc reference
docRef.get().addOnCompleteListener(new OnCompleteListener<DocumentSnapshot>() {
    @Override
    public void onComplete(@NonNull Task<DocumentSnapshot> task) {
        if (task.isSuccessful()) {
            DocumentSnapshot document = task.getResult();
            if (document.exists()) // if username is present
            { 
                String email=document.getData().email; //get email from document
                mAuth.signInWithEmailAndPassword(email, password) //signin with email
        .addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
            @Override
            public void onComplete(@NonNull Task<AuthResult> task) {
                if (task.isSuccessful()) // if password and email id matches
                {
                    // Sign in success, update UI with the signed-in user's information
                    Log.d(TAG, "signInWithEmail:success");
                } else {
                    // If sign in fails, display a message to the user.
                    Log.w(TAG, "signInWithEmail:failure", task.getException());
                }
            }
        });
            } else {
                Log.d(TAG, "No such document");
                //add code (user not found/registered) 
            }
        } else {
            Log.d(TAG, "get failed with ", task.getException());
        }
    }
});

修改您的代码：

FirebaseFirestore db = FirebaseFirestore.getInstance();
private void registerUser (){
        String email = editTextEmail.getText().toString().trim();
        String username = editTextUsername.getText().toString().trim();
        String password = editTextPassword.getText().toString().trim();

        if (email.isEmpty()) {
            editTextEmail.setError("Email is required");
            editTextEmail.requestFocus();
            return;
        }

        if (!Patterns.EMAIL_ADDRESS.matcher(email).matches()) {
            editTextEmail.setError(("Please enter a valid email"));
            editTextEmail.requestFocus();
            return;
        }

        if (password.isEmpty()) {
            editTextPassword.setError("Password is required");
            editTextPassword.requestFocus();
            return;
        }

        if (password.length() < 6) {
            editTextPassword.setError("Your password must be at least 6 characters");
            return;
        }

        progressBar.setVisibility(View.VISIBLE);
        Map<String, Object> user = new HashMap<>();
        user.put("email", email);

        db.collection("profiles").document(username) //username is set as firestore document name, profiles is the collection name
        .set(user)  //Store the email in above document.
        .addOnSuccessListener(new OnSuccessListener<Void>() {
            @Override
            public void onSuccess(Void aVoid) // If data is added successfully
            {
                mAuth.createUserWithEmailAndPassword(email, password).addOnCompleteListener(new OnCompleteListener<AuthResult>() {
            @Override
            public void onComplete(@NonNull final Task<AuthResult> task) {
                if (task.isSuccessful()) {
                    // send user verification link using firebase

                    FirebaseUser user = mAuth.getCurrentUser();
                    user.sendEmailVerification().addOnSuccessListener(new OnSuccessListener<Void>() {
                        @Override
                        public void onSuccess(Void aVoid) {
                            Toast.makeText(ChildSignUpActivity.this, "Verification Email Has Been Sent", Toast.LENGTH_SHORT).show();
                        }
                    }).addOnFailureListener(new OnFailureListener() {
                        @Override
                        public void onFailure(@NonNull Exception e) {
                            Toast.makeText(getApplicationContext(), task.getException().getMessage(), Toast.LENGTH_SHORT).show();;
                        }
                    });



                    Toast.makeText(getApplicationContext(), "User Register Succesfull", Toast.LENGTH_SHORT).show();
                } else {

                    if(task.getException() instanceof FirebaseAuthUserCollisionException) {
                        Toast.makeText(getApplicationContext(), "User already exists", Toast.LENGTH_SHORT).show();
                    }else{
                        Toast.makeText(getApplicationContext(), task.getException().getMessage(), Toast.LENGTH_SHORT);
                    }

                }
            }
        });

            }
        });

    }

Answer 2

“因此，将使用将显示在身份验证页面上的用户名创建帐户。” 您是否希望用户名出现在 firebase 控制台的身份验证页面上。 我不认为可以这样做或为什么应该这样做。 正确的方法是使用 email 和密码创建用户，然后使用他想要的用户名更新用户的个人资料，如下所示 -

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

UserProfileChangeRequest profileUpdates = new UserProfileChangeRequest.Builder()
        .setDisplayName("Jane Q. User")
        .build();

user.updateProfile(profileUpdates)
        .addOnCompleteListener(new OnCompleteListener<Void>() {
            @Override
            public void onComplete(@NonNull Task<Void> task) {
                if (task.isSuccessful()) {
                    Log.d(TAG, "User profile updated.");
                }
            }
        });

稍后，如果您需要用户名，您可以使用 -

FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();
if (user != null) {
    for (UserInfo profile : user.getProviderData()) {
        String name = profile.getDisplayName();
    }
}

解决我的问题的最佳方法是首先使用 Firestore 保存用户名的用户数据，然后使用致命编码员帖子中的技巧然后应该修复它并让您登录。
