你好，Firebase专家最近我用实时数据库实现了防火墙的身份验证，现在我想上传用户的个人资料图像又如何呢？

Question

注册活动屏幕截图

我实现了从图片库中提取图像的其余部分，并将其设置为图像视图！现在我想要的功能是上传用户个人资料图像和注册细节，也请注意，是否需要在用户模型类中增加一个变量？以及我必须在后面添加哪些参数、构造函数、getter或setter。下面也给出了用户模型类的代码，谢谢:)

//这是注册用户的函数：

        private void register_doctor () {
            String dname = et_name.getText().toString().trim();
            String demail = et_email.getText().toString().trim();
            String dpass = et_pass.getText().toString().trim();
            String dcpass = et_cnf_pass.getText().toString().trim();
            String dcontact = et_contact.getText().toString().trim();
            String dcity = et_city.getText().toString().trim();
            String dage = et_age.getText().toString().trim();


            if (dname.isEmpty()) {
                et_name.setError("Full Name is Required");
                et_name.requestFocus();
                return;
            }
            if (demail.isEmpty()) {
                et_email.setError("Email is Required");
                et_email.requestFocus();
                return;
            }

            if (dpass.isEmpty()) {
                et_pass.setError("Password is Required");
                et_pass.requestFocus();
                return;
            }

            if (dpass.length() < 6) {
                et_pass.setError("Password Length Should be greater than 6 characters");
                et_pass.requestFocus();
                return;
            }

            if (dcpass.isEmpty()) {
                et_cnf_pass.setError("Password is Required");
                et_cnf_pass.requestFocus();
                return;
            }
            if (!dcpass.equals(dpass)) {
                et_cnf_pass.setError("Password Does not Matched!");
                et_cnf_pass.requestFocus();
                return;
            }

            if (dcontact.isEmpty()) {
                et_contact.setError("Contact is Required");
                et_contact.requestFocus();
                return;
            }

            if (dcity.isEmpty()) {
                et_city.setError("City is Required");
                et_city.requestFocus();
                return;
            }

            if (dage.isEmpty()) {
                et_age.setError("Age is Required");
                et_age.requestFocus();
                return;
            }

            progressBar.setVisibility(View.VISIBLE);

            mAuth.createUserWithEmailAndPassword(demail, dpass)
                    .addOnCompleteListener(new OnCompleteListener<AuthResult>() {
                        @Override
                        public void onComplete(@NonNull Task<AuthResult> task) {
                            if (task.isSuccessful()) {
                                User user = new User(dname, demail, dcontact, dcity, dage);
                                
                                FirebaseDatabase.getInstance().getReference("doctors")
                                        .child("Doctors_Registration")
//                                        .child(FirebaseAuth.getInstance().getCurrentUser().getUid())
                                        .child(demail.replace(".", ","))
                                        .setValue(user)
                                        .addOnCompleteListener(new OnCompleteListener<Void>() {
                                            @Override
                                            public void onComplete(@NonNull Task<Void> task) {

                                                if (task.isSuccessful()) {
                                                    Toast.makeText(signup.this, "Doctor Registered", Toast.LENGTH_SHORT).show();
                                                    progressBar.setVisibility(View.GONE);
                                                } else {
                                                    Toast.makeText(signup.this, "Failed to Registered, Try Again!" + task.getException(), Toast.LENGTH_LONG).show();
                                                    progressBar.setVisibility(View.GONE);
                                                }
                                            }
                                        });
                            } else {
                                Toast.makeText(signup.this, "Failed to Registered, Try Again!", Toast.LENGTH_LONG).show();
                                progressBar.setVisibility(View.GONE);
                            }
                        }
                    });

        }




// here is my user-model class code
package com.example.iotbaseddriverhealthmonitoring;

public class User {
    public String name, email, password, contact, city, age;
    public  User(){
    }
    public User(String name, String email, String contact, String city, String age){
        this.name = name;
        this.email = email;
        this.contact = contact;
        this.city = city;
        this.age = age;
    }
}

我认为您的意思是setPhotoUri() (然后更新用户)：

来自[消]火基文件

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

UserProfileChangeRequest profileUpdates = new UserProfileChangeRequest.Builder()
    .setDisplayName("Jane Q. User")
    .setPhotoUri(Uri.parse("https://example.com/jane-q-user/profile.jpg"))
    .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.");
            }
        }
    });

还可以将图像存储在Firebase存储中，然后将该下载链接保存在Firebase数据库中。
