java - 尝试将图像保存到 firebase 存储时，android studio 出现错误

Question

我正在制作一个 Android 应用程序，这个应用程序的一部分是为用户保存显示图像。下面的代码块是将图像保存在 firebase 存储中的方法。我已经在 firebase 中配置了规则，并在 list 文件中设置了访问图像的权限。该方法在用户选择图库中的图像后被调用。选择图像有效，但保存部分无效。我已经做了很多方法来解决这个问题，但似乎没有任何效果。 IDE 无法检测到的代码中似乎存在错误。错误在运行时。用户在图库中选择图片后应用关闭。

mStorage 已经在onCreate 方法中初始化。所选图像保存在 uriProfileImage 中。 uploadProgress 只是一个进度条。

private void uploadImageToFirebaseStorage() {
mStorage = FirebaseStorage.getInstance().getReference();
StorageReference profileImageRef = mStorage.child("displayImages/" + System.currentTimeMillis() + uriProfileImage.getPath().substring(uriProfileImage.getPath().lastIndexOf(".")));
uploadProgress.setVisibility(View.VISIBLE);
if (uriProfileImage != null) {
    profileImageRef.putFile(uriProfileImage).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
        @Override
        public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
            uploadProgress.setVisibility(View.GONE);
            profileImageUrl = taskSnapshot.getDownloadUrl().toString();
        }
    }).addOnFailureListener(new OnFailureListener() {
        @Override
        public void onFailure(@NonNull Exception e) {
            uploadProgress.setVisibility(View.GONE);
            Toast.makeText(getActivity(), e.getMessage(), Toast.LENGTH_SHORT).show();
        }
    });
}

我得到了这个错误

请帮帮我。我已经尝试了很多方法来解决它，但我根本没有取得任何进展。

Answer 1

伙计们，我找到了解决方案。我发布这个是为了帮助其他有同样问题的人。

问题是我提供的 StorageReference 是错误的。

我把它改成

mStorage = FirebaseStorage.getInstance().getReference();
StorageReference profileImageRef = mStorage.child("displayImages/" + System.currentTimeMillis() + uriProfileImage.getPath().substring(uriProfileImage.getPath().lastIndexOf(".")));

到

StorageReference profileImageRef = FirebaseStorage.getInstance().getReference("displayImages/"+System.currentTimeMillis()+".jpg");

似乎之前的 StorageReference 返回了一个无效的存储引用。我还更新了我的 firebase 存储和数据库依赖项。

另一件事是，上面用于获取上传图片的 downloadUrl 的代码不起作用。

所以我把它改成了

profileImageUrl = taskSnapshot.getDownloadUrl().toString();

到

profileImageUrl = taskSnapshot.getMetadata().getReference().getDownloadUrl().toString();

希望对您有所帮助。
