【问题描述】:
我已经为我的应用设置了 firebase 存储,并在应用和 firebase 控制台上添加了匿名身份验证代码。
一开始可以,但是不知道为什么停止了,说用户没有访问对象的权限
匿名身份验证已正确设置,我确实看到它工作正常,代码几乎就像 Google Firebase 文档
日志猫:
D/FirebaseAuth:signInAnonymously:onComplete:true
D/Firebase 身份验证: onAuthStateChanged:signed_in: (随机认证用户 id)
...当我从 firebase 请求项目时
E/StorageUtil:获取令牌时出错 java.util.concurrent.ExecutionException:com.google.firebase.FirebaseException:发生内部错误。 [遇到内部错误。] I/DpmTcmClient:RegisterTcmMonitor 来自:com.android.okhttp.TcmIdleTimerMonitor W/NetworkRequest:无身份验证 请求 E/StorageException 的令牌:已发生 StorageException。 用户无权访问此对象。 代码:-13021 HttpResult:403
有人可以帮忙吗?
声明变量
private FirebaseAuth mAuth;
private FirebaseAuth.AuthStateListener mAuthListener;
关于 OnCreate 方法
mAuthListener = new FirebaseAuth.AuthStateListener() {
@Override
public void onAuthStateChanged(@NonNull FirebaseAuth firebaseAuth) {
FirebaseUser user = firebaseAuth.getCurrentUser();
if (user != null) {
// User is signed in
Log.d("FirebaseAuth", "onAuthStateChanged:signed_in:" + user.getUid());
} else {
// User is signed out
Log.d("FirebaseAuth", "onAuthStateChanged:signed_out");
}
// ...
}
};
mAuth.signInAnonymously()
.addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(@NonNull Task<AuthResult> task) {
Log.d("FirebaseAuth", "signInAnonymously:onComplete:" + task.isSuccessful());
// If sign in fails, display a message to the user. If sign in succeeds
// the auth state listener will be notified and logic to handle the
// signed in user can be handled in the listener.
if (!task.isSuccessful()) {
Log.w("FirebaseAuth", "signInAnonymously", task.getException());
Toast.makeText(SingleMemeEditor.this, "Authentication failed.",
Toast.LENGTH_SHORT).show();
}
// ...
}
});
以及从存储中获取的方法:
Bitmap bmp;
final Context lContext = context; //getting the MainActivity Context
final String lFileName = fileName; //filename to download
final String lCatPath = catPath; //internal categorization folder
FirebaseStorage storage = FirebaseStorage.getInstance();
// Create a storage reference from our app
StorageReference storageRef = storage.getReferenceFromUrl(context.getResources().getString(R.string.firebase_bucket));
// Create a reference with an initial file path and name
StorageReference filesRef = storageRef.child("files/" + fileName);
try
{
final File localFile = File.createTempFile("images", "jpg");
filesRef.getFile(localFile).addOnSuccessListener(new OnSuccessListener<FileDownloadTask.TaskSnapshot>()
{
@Override
public void onSuccess(FileDownloadTask.TaskSnapshot taskSnapshot)
{
// Local temp file has been created
File file = new File(getDirectory(lContext)
+ File.separator + lCatPath + File.separator + lFileName);
try
{
Boolean b = file.createNewFile();
if(b)
{
FileInputStream in = new FileInputStream(localFile);
FileOutputStream out = new FileOutputStream(file);
// Transfer bytes from in to out
byte[] buf = new byte[(int)localFile.length()];
int len;
while ((len = in.read(buf)) > 0) {
out.write(buf, 0, len);
}
in.close();
out.close();
}
Drawable.createFromPath(file.getPath())).getBitmap());
}
catch (IOException ex)
{
// Handle any errors
Log.e("CopyingFromTemp", ex.getMessage());
}
}
}).addOnFailureListener(new OnFailureListener()
{
@Override
public void onFailure(@NonNull Exception ex)
{
// Handle any errors
Log.e("FirebaseDownloadError", ex.getMessage());
}
});
}
catch(Exception ex)
{
Log.e("FirebaseDownloadError", ex.getMessage());
}
我也在使用标准的安全规则:
match /{allPaths=**} {
allow read, write: if request.auth != null;
}
【问题讨论】:
-
显示存储的安全规则和重现问题的最少代码(流程在这里相当重要)。
-
帖子已编辑以添加您要求的内容
-
不幸的是,该代码没有显示您如何确保在上传图像之前对用户进行身份验证。在开始实际上传之前,您可能需要添加一个简单的检查
if (FirebaseAuth.getInstance().getCurrentUser !0 null)。 -
因为我正在使用匿名身份验证,并且我看到身份验证“成功”,我认为这实际上是不必要的,无论如何感谢确保用户通过身份验证的代码,但是因为我之前作为答案发布(由于我必须等待一天,所以没有接受它是正确的)解决方案是退出当前经过身份验证的“用户”
