问题描述

到目前为止，从 Firebase 存储文件中获取 url 的方法，我曾经这样做过taskSnapshot.getDownloadUrl，但现在不推荐使用，我应该使用哪种方法?

Until now, the way to get the url from file on Storage in Firebase, I used to do thistaskSnapshot.getDownloadUrl, but nowadays is deprecated, which method I should use?

推荐答案

正如 Doug 所说，你需要在 Task 中运行它

As Doug says, you will need to run it inside a Task

这里有一个关于你需要如何实现它的提示

Here is a hint of how you need to implement it

final StorageReference ref = storageRef.child("your_REF");
uploadTask = ref.putFile(file);

    Task<Uri> urlTask = uploadTask.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 ref.getDownloadUrl();
        }
    }).addOnCompleteListener(new OnCompleteListener<Uri>() {
        @Override
        public void onComplete(@NonNull Task<Uri> task) {
            if (task.isSuccessful()) {
                Uri downloadUri = task.getResult();
                String downloadURL = downloadUri.toString();
            } else {
                // Handle failures
                // ...
            }
        }
    });
