我正在尝试建立博客应用。这个想法是，在用户登录或注册后，他们将被定向到设置页面，在其中选择个人资料图片和名称。图片将保存到Firestore存储中，然后将详细信息记录在Firestore数据库中。
因此，在设置页面加载时，假设首先检查该用户是否具有现有的数据图片和名称，然后让他们更改或填写其详细信息。
一切正常，直到用户尝试上传他的照片和姓名为止。图片成功存储在Firestore中，然后继续登录Firestore并返回错误
用户无权访问此对象。
我的应用程序中的其他活动具有相同的功能，并且它们均返回相同的错误。
我的设置逻辑是这样的：
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_setup);
firebaseAuth = FirebaseAuth.getInstance();
user_id = firebaseAuth.getCurrentUser().getUid();
firebaseFirestore = FirebaseFirestore.getInstance();
storageReference = FirebaseStorage.getInstance().getReference();
setupImage = findViewById(R.id.setup_image);
setupName = findViewById(R.id.setup_name);
setupBtn = findViewById(R.id.setup_btn);
setupProgress = findViewById(R.id.setup_progress);
setupProgress.setVisibility(View.VISIBLE);
setupBtn.setEnabled(false);
firebaseFirestore.collection("Users").document(user_id).get().addOnCompleteListener(new OnCompleteListener<DocumentSnapshot>() {
@Override
public void onComplete(@NonNull Task<DocumentSnapshot> task) {
if (task.isSuccessful()) {
if (task.getResult().exists()) {
String name = task.getResult().getString("name");
String image = task.getResult().getString("image");
mainImageURI = Uri.parse(image);
setupName.setText(name);
RequestOptions placeholderRequest = new RequestOptions();
placeholderRequest.placeholder(R.drawable.dummy);
Glide.with(Setup.this).setDefaultRequestOptions(placeholderRequest).load(image).into(setupImage);
}
} else {
String error = task.getException().getMessage();
Toast.makeText(Setup.this, "(FIRESTORE Retrieve Error) : " + error, Toast.LENGTH_LONG).show();
}
setupProgress.setVisibility(View.INVISIBLE);
setupBtn.setEnabled(true);
}
});
setupBtn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
final String user_name = setupName.getText().toString();
if (!TextUtils.isEmpty(user_name) && mainImageURI != null) {
setupProgress.setVisibility(View.VISIBLE);
if (isChanged) {
user_id = firebaseAuth.getCurrentUser().getUid();
File newImageFile = new File(mainImageURI.getPath());
try {
compressedImageFile = new Compressor(Setup.this)
.setMaxHeight(125)
.setMaxWidth(125)
.setQuality(20)
.compressToBitmap(newImageFile);
} catch (IOException e) {
e.printStackTrace();
}
ByteArrayOutputStream baos = new ByteArrayOutputStream();
compressedImageFile.compress(Bitmap.CompressFormat.JPEG, 100, baos);
byte[] thumbData = baos.toByteArray();
final UploadTask image_path = storageReference.child("profile_images").child(user_id + ".jpg").putBytes(thumbData);
Task<Uri> urlTask = image_path.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();
}
// Continue with the task to get the download URL
return storageReference.getDownloadUrl();
}
}).addOnCompleteListener(new OnCompleteListener<Uri>() {
@Override
public void onComplete(@NonNull Task<Uri> task) {
if (task.isSuccessful()) {
Uri downloadUri = task.getResult();
storeFirestore(task, user_name, downloadUri);
} else {
Toast
.makeText
(Setup.this, task.getException().getMessage(), Toast.LENGTH_SHORT).show();
setupProgress.setVisibility(View.INVISIBLE);
}
}
});
} else {
storeFirestore(null, user_name, null);
}
}else {
Toast.makeText(Setup.this, "Please make sure to put a name and pick a picture", Toast.LENGTH_LONG).show();
}
}
});
setupImage.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if (ContextCompat.checkSelfPermission(Setup.this, Manifest.permission.READ_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {
Toast.makeText(Setup.this, "Permission Denied", Toast.LENGTH_LONG).show();
ActivityCompat.requestPermissions(Setup.this, new String[]{Manifest.permission.READ_EXTERNAL_STORAGE}, 1);
} else {
BringImagePicker();
}
} else {
BringImagePicker();
}
}
});
}
private void storeFirestore(@NonNull Task<Uri> task, String user_name, Uri downloadUri) {
if (task == null) {
downloadUri = mainImageURI;
}
Map<String, String> userMap = new HashMap<>();
userMap.put("name", user_name);
userMap.put("image", downloadUri.toString());
firebaseFirestore.collection("Users").document(user_id).set(userMap).addOnCompleteListener(new OnCompleteListener<Void>() {
@Override
public void onComplete(@NonNull Task<Void> task) {
if (task.isSuccessful()) {
Toast.makeText(Setup.this, "The user Settings are updated.", Toast.LENGTH_LONG).show();
Intent mainIntent = new Intent(Setup.this, MainActivity.class);
startActivity(mainIntent);
finish();
} else {
String error = task.getException().getMessage();
Toast.makeText(Setup.this, "(FIRESTORE Error) : " + error, Toast.LENGTH_LONG).show();
}
setupProgress.setVisibility(View.INVISIBLE);
}
});
}
private void BringImagePicker() {
CropImage.activity()
.setGuidelines(CropImageView.Guidelines.ON)
.setAspectRatio(1, 1)
.start(Setup.this);
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == CropImage.CROP_IMAGE_ACTIVITY_REQUEST_CODE) {
CropImage.ActivityResult result = CropImage.getActivityResult(data);
if (resultCode == RESULT_OK) {
mainImageURI = result.getUri();
setupImage.setImageURI(mainImageURI);
isChanged = true;
} else if (resultCode == CropImage.CROP_IMAGE_ACTIVITY_RESULT_ERROR_CODE) {
Exception error = result.getError();
}
}
}
因此，setupButton触发上传，并在将图片存储在Firebase Storage中之后调用storeInFirestore方法。
我在Firestore中有这样的规则
service cloud.firestore {
match /databases/{database}/documents {
match /{document=**} {
allow read, write: if request.auth.uid != null;
}
}
}
仔细观察，我发现该文件已在Firebase Storage中上传，但是当我尝试获取下载Uri时返回了错误。所以else语句
addOnCompleteListener(new OnCompleteListener<Uri>() {
@Override
public void onComplete(@NonNull Task<Uri> task) {
if (task.isSuccessful()) {
Uri downloadUri = task.getResult();
storeFirestore(task, user_name, downloadUri);
} else {
Toast
.makeText
(Setup.this, task.getException().getMessage(), Toast.LENGTH_SHORT).show();
是返回错误的原因，因此永远不会触发登录Firestore的方法。
由于我关注文档，因此我尝试获取downloadUri的方式出了问题。
我的存储规则也是如此
service firebase.storage {
match /b/{bucket}/o {
match /{allPaths=**} {
allow read, write: if request.auth != null;
}
}
}
