使用 getDownloadUrl() 的 Firebase 存储"retrieves a long lived download URL"现已弃用

Question

此getDownloadUrl()方法在更新为

'

com.google.firebase：firebase-storage：15.0.2'

官方网站上没有其他方式来实现网址，那么有什么方法可以以非弃用的方式实现网址吗？

/** @deprecated */
@Deprecated
@Nullable
public Uri getDownloadUrl() {
StorageMetadata var1;
return (var1 = this.getMetadata()) != null ? var1.getDownloadUrl() : null;
}
}

Answer 1

在文档中它是这样说的：

StorageMetadata类的getDownloadUrl()和getDownloadUrls()方法现已弃用。请改用StorageReference中的getDownloadUrl()。

所以你需要使用StorageReference里面的getDownloadUrl()

public Task<Uri> getDownloadUrl ()

异步检索具有可撤销令牌的长期下载 URL。此功能可用于与他人共享文件，但如果需要，开发者可以在 Firebase 控制台中撤消此功能。

Answer 2

final StorageReference filePath = mImageStore.child("profile_images").child("full_image").child(userId + ".jpg");
filePath.getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {
@Override
public void onSuccess(Uri uri) {
//Bitmap hochladen
uploadBitMap(uri.toString());
}
});strong text

或

final UploadTask uploadTask = thumb_file.putBytes(thumb_bite);
uploadTask.addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
@Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
//Url laden
taskSnapshot.getStorage().getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {
@Override
public void onSuccess(Uri uri) {
Map imageUrls = new HashMap();
imageUrls.put("image", fullImageUrl);
imageUrls.put("thumb_image", uri.toString());
//In database
mAlarmsDatabaseReference.updateChildren(imageUrls).addOnCompleteListener(new OnCompleteListener<Void>() {
@Override
public void onComplete(@NonNull Task<Void> task) {
//Progressbar beende + Bild wieder anzeigen
progressBar.setVisibility(View.GONE);
circleProfilePicture.setVisibility(View.VISIBLE);
if(task.isSuccessful()){
Toast.makeText(SettingsActivity.this, getResources().getString(R.string.ProfilbildUpdate), Toast.LENGTH_SHORT).show();
}else{
Toast.makeText(SettingsActivity.this, "FAILED", Toast.LENGTH_SHORT).show();
}
}
});
}
});
}
});

final UploadTask uploadTask = thumb_file.putBytes(thumb_bite(; uploadTask.addOnSuccessListener(new OnSuccessListener(( { @Override public void onSuccess(UploadTask.TaskSnapshot taskSnapshot( {

//Url laden
taskSnapshot.getStorage().getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {
@Override
public void onSuccess(Uri uri) {
Map imageUrls = new HashMap();
imageUrls.put("image", fullImageUrl);
imageUrls.put("thumb_image", uri.toString());
//In database
mAlarmsDatabaseReference.updateChildren(imageUrls).addOnCompleteListener(new OnCompleteListener<Void>() {
@Override
public void onComplete(@NonNull Task<Void> task) {
//Progressbar beende + Bild wieder anzeigen
progressBar.setVisibility(View.GONE);
circleProfilePicture.setVisibility(View.VISIBLE);
