无法写入 Firebase 存储 onSuccess 侦听器内的 Firebase 数据库

Question

我正在尝试存储将文件上传到 Firebase 存储后获得的 Firebase 存储 URL，但由于我无法理解的原因，我无法写入 Firebase 上的某个位置Storage onSuccess 侦听器内部的数据库。任何想法为什么？如果这不是存储上传文件 URL 位置的正确方法，那么什么才是？

我似乎找不到这方面的例子。这是为了 android。谢谢

你想要完成的是完全可行的，这里有一个例子

    StorageReference fileRef = ....;
    Uri fileUri = ....;
    UploadTask uploadTask = fileRef.putFile(fileUri);

    uploadTask.addOnFailureListener(new OnFailureListener() {
        @Override
        public void onFailure(@NonNull Exception exception) {
            // Handle unsuccessful uploads
            Log.d("TAG", "onFailure: " + exception);

        }
    }).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
        @Override
        public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
       // This is the URL you are looking for, here you should insert it into your db instance...Something like this
         Uri downloadUrl = taskSnapshot.getDownloadUrl();

         DatabaseReference dbRef = FirebaseDatabase.getInstance().getReference(); 
         dbRef.child("uploadUrls").child("url1").setValue(downloadUrl.toString());
        }
    });

希望对您有所帮助

 DatabaseReference dbRef = FirebaseDatabase.getInstance().getReference();

 uploadTask.addOnFailureListener(new OnFailureListener() {
            @Override
            public void onFailure(@NonNull Exception exception) {
                // Handle unsuccessful uploads
                Log.d("TAG", "onFailure: " + exception);

            }
        }).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
            @Override
            public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
           // This is the URL you are looking for, here you should insert it into your db instance...Something like this
             Uri downloadUrl = taskSnapshot.getDownloadUrl();

            addData(downloadUrl.toString());

            }
        });


public void addData(String downloadUrl)
{

dbRef.child("uploadUrls").child("url1").setValue(downloadUrl);

}
