taskSnapshot.getDownloadUrl()方法不起作用

Question

private void uploadImageToFirebaseStorage() {
    StorageReference profileImageRef =
        FirebaseStorage.getInstance().getReference("profilepics/" + System.currentTimeMillis() + ".jpg");

    if (uriProfileImage != null) {
        progressBar.setVisibility(View.VISIBLE);
        profileImageRef.putFile(uriProfileImage)
            .addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
                @Override
                public void onSuccess(@NonNull UploadTask.TaskSnapshot taskSnapshot) {
                    progressBar.setVisibility(View.GONE);
                    profileImageUrl = taskSnapshot.**getDownloadUrl**().toString();
                }
            })
            .addOnFailureListener(new OnFailureListener() {
                @Override
                public void onFailure(@NonNull Exception e) {
                    progressBar.setVisibility(View.GONE);
                    Toast.makeText(ProfileActivity.this, e.getMessage(), Toast.LENGTH_SHORT).show();
                }
            });
    }
}

taskSnapshot.getDownloadUrl() 不工作的方法在它下面出现红线

Answer 1

在Firebase Storage API版本16.0.1中.使用taskSnapshot对象的getDownloadUrl()方法已更改.现在您可以使用'
Firebase Storage API 从firebase存储中获取下载URL.

Answer 2

要从存储获取imageUrl路径，请使用以下代码：

uploadTask.addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
    @Override
    public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
        if (taskSnapshot.getMetadata() != null) {
            if (taskSnapshot.getMetadata().getReference() != null) {
                Task<Uri> result = taskSnapshot.getStorage().getDownloadUrl();
                result.addOnSuccessListener(new OnSuccessListener<Uri>() {
                    @Override
                    public void onSuccess(Uri uri) {
                        String imageUrl = uri.toString();
                        //createNewPost(imageUrl);
                    }
                });
            }
        }
    }});

就这些

注意：不要忘记在uploadFile方法中初始化StorageReference和UploadTask。

尝试使用它会从FireBase存储下载图像

FireBase库版本16.0.1

Task<Uri> result = taskSnapshot.getMetadata().getReference().getDownloadUrl();
result.addOnSuccessListener(new OnSuccessListener<Uri>() {
      @Override
      public void onSuccess(Uri uri) {
             String photoStringLink = uri.toString();
      }
});
