Android Firebase - 使用 Profiles 照片进行用户注册

提问于
浏览 次
2

我一直在浏览Firebase文档，以及在stackoverflow，google和YouTube上搜索以下内容：

创建允许电子邮件，密码和 Profiles 照片的用户注册 .

我能够成功地为用户添加他们的电子邮件和密码，但我似乎无法获取其他信息（最重要的是 Profiles 照片） . 所有教程和文档都显示了某人（已登录）用户可以如何将照片上传到firebase，但不能将某人注册 . 有人可以帮忙，我怎样才能获得新用户上传的 Profiles 照片和名字/姓氏？

我正在使用FirebaseAuth添加用户 .

这是我到目前为止：

checkmarkImage.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {


        auth.createUserWithEmailAndPassword(emailET.getText().toString(), passwordET.getText().toString())
            .addOnCompleteListener(RegisterActivity.this, new OnCompleteListener() {
                            @Override
                            public void onComplete(@NonNull Task task) {
                                        Toast.makeText(RegisterActivity.this, "createUserWithEmail:onComplete:" + task.isSuccessful(), Toast.LENGTH_SHORT).show();
                                          //progressBar.setVisibility(View.GONE);
                                if (!task.isSuccessful()) {
                                              Toast.makeText(RegisterActivity.this, "Authentication failed." + task.getException(),
                                                      Toast.LENGTH_SHORT).show();
                                } else {
                                        startActivity(new Intent(RegisterActivity.this, HomeActivity.class));
                                        finish();
                                          }
                                          }
                                  });
                      }
                  });

        uploadProfilePhoto.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                handleChooseImage(view);
            }
        });


    }

    //END OF onCreate

    //Separate methods

    //Actually opens the CameraRoll
        public void handleChooseImage(View v) {
            Intent i = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
            startActivityForResult(i, SELECTED_PICTURE);  //then goes to onActivityResult
        }
        public void handleInsertData(View v) {

        }

    public void onActivityResult(int requestCode, int resultCode, Intent imageReturnedIntent) {
        super.onActivityResult(requestCode, resultCode, imageReturnedIntent);
        switch (requestCode) {
            case 0:
                if(requestCode == RESULT_OK) {
                    Log.i("RegisterActivity", "case 0");
                }
                break;
            case 1:
                if(resultCode == RESULT_OK) {
                    Uri selectedImage = imageReturnedIntent.getData();
                    Log.i("RegisterActivity", "selected image = " + selectedImage);

                }
                break;
        }
    }

    这可能有点晚了，但是对于其他来这里寻求可靠答案的人，我会告诉你我是如何做到的 .

    我有一个POJO类CreatedUserDetail，带有电子邮件和照片字段 .

    我还创建了一个User类：

    public class User{
private String uid;
private String password;
private String email;
private String photo;

public User( String email, String photo, String password ){
    this.email = email;
    this.photo = photo;
    this.password = password;
}

public void saveToFirebase(){
    CreatedUserDetail userDetail = new CreatedUserDetail();
    userDetail.setEmail( email );
    userDetail.setImage( photo );

    FirebaseDatabase.getInstance()
            .getReference()
            .child( "Users" )
            .child( uid ).setValue( userDetail );
}

private void uploadProfileImage(){
    final StorageReference mStorageReference = FirebaseStorage.getInstance()
            .getReference()
            .child( "pics" +
                    uid +
                    photo.substring( photo.lastIndexOf( "." ) ) );

    UploadTask uploadTask = mStorageReference.putFile( Uri.fromFile( new File( photo ) ) );
    uploadTask.continueWithTask( new Continuation< UploadTask.TaskSnapshot, Task< Uri > >(){
        @Override
        public Task< Uri > then( @NonNull Task< UploadTask.TaskSnapshot > task ) throws Exception{
            if( !task.isSuccessful() )
                throw task.getException();

            return mStorageReference.getDownloadUrl();
            }
        } ).addOnCompleteListener( new OnCompleteListener< Uri >(){
        @Override
        public void onComplete( @NonNull Task< Uri > task ){
            if( task.isSuccessful() ){
                photo = task.getResult().toString();
                FirebaseDatabase.getInstance().getReference( "Users" )
                        .child( uid )
                        .child( "image" )
                        .setValue( photo );
            }
        }
    } );
}

public void RegisterUser( final OnUserRegistrationCallback onUserRegistrationCallback ){
    FirebaseAuth.getInstance()
            .createUserWithEmailAndPassword( email, password )
            .addOnSuccessListener( new OnSuccessListener< AuthResult >(){
                @Override
                public void onSuccess( AuthResult authResult ){
                    uid = authResult.getUser().getUid();
                    saveToFirebase();
                    uploadProfileImage();
                }
            } )
            .addOnFailureListener( new OnFailureListener(){
                @Override
                public void onFailure( @NonNull Exception e ){
                }
            } );
}

    }

    如您所见，它具有RegisterUser功能，该功能首先使用给定的电子邮件和密码在Firebase身份验证中创建用户 . 注册后，我在Firebase数据库中创建了一个用户，其中包含电子邮件和LOCAL PATH照片 . 同时，它还会将照片上传到Firebase存储 . 最后，在完成上传后，我使用最近上传的照片的downloadUrl更新Firebase数据库节点 .

    在活动中，我只是这样做：

    mUserWithEmailAndPassword = new User( mEmailToVerify, mLocalPath, mPass );
    mUserWithEmailAndPassword.RegisterUser();

    就这样 . 您可以包含一个回调来显示Toast或重定向到另一个活动 .

    您需要先注册，然后在存储中上传用户图像，这是标准方式 .

    因为根据firebase存储默认规则 user != null 所以必须用户身份验证状态不为null，否则你可以将firebase规则更改为public（这不是更好）

    我希望这能帮到您 .

    auth.createUserWithEmailAndPassword(email, password)
                        .addOnCompleteListener(SignupActivity.this, new OnCompleteListener<AuthResult>() {
                            @Override
                            public void onComplete(@NonNull Task<AuthResult> task) {
                                     if (!task.isSuccessful()) {
                                    aDialog.show();
                                } else {
                                    final String uid = task.getResult().getUser().getUid();

                                    StorageReference filepath = mStorage.child("user_profile").child(mImageUri.getLastPathSegment());
                                    filepath.putFile(mImageUri).addOnProgressListener(new OnProgressListener<UploadTask.TaskSnapshot>() {
                                        @Override

                                            double progress = (100.0 * taskSnapshot.getBytesTransferred()) / taskSnapshot.getTotalByteCount();
                                            if (progress == 100) {
                                                hideProgressDialog();
                                                //upload();

    您可以上传图像，无论用户在firebase上注册，但是，当用户登录时，您需要用户引用来保存图像以便再次获取图像，如果用户是，则无法让用户参考尚未注册 . 说得通？ :)
