将视频上传到Android中的Firebase Cloud Storage后，我无法获取视频下载网址.getDownloadUrl无法正常工作
问题描述：
我需要这个:
我可以将视频文件成功上传到Firebase Storage，但没有下载网址.这是我的上传代码:
I can upload video file successfully to Firebase Storage but I don't get the download url. Here is my upload code:
Task<Uri> uriTask = 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();
downloadurl = mStorageRef.getDownloadUrl().toString();
return mStorageRef.child(name1).getDownloadUrl();
}
}).addOnCompleteListener(new OnCompleteListener<Uri>() {
@Override
public void onComplete(@NonNull Task<Uri> task) {
if(task.isSuccessful())
downloadurl = task.getResult().toString();
Map<String,Object> user = new HashMap<>();
user.put("videoname",name1);
user.put("videolink",downloadurl);
firebaseFirestore.collection("videos").document(userID).collection("video").document().set(user).addOnSuccessListener(new OnSuccessListener<Void>() {
@Override
public void onSuccess(Void aVoid) {
Toast.makeText(getActivity(),"Uploaded Successfully",Toast.LENGTH_SHORT).show();
progressBar.setVisibility(View.GONE);
}
});
}
});
}
})
答
尝试一下
private Uri uri; //global variable
当用户从手机中选择视频时，
在 onActivityResult()内部设置uri
Inside onActivityResult() set uri when the user selects a video from phone
onActivityResult(int requestCode, int resultCode, Intent data)
uri = data.getData();
最终获得下载网址
final StorageReference ref = storageReference.child("firebaseFilePath");
ref.putFile(uri).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
@Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
ref.getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {
@Override
public void onSuccess(Uri uri) {
//now sUrl contains downloadURL
sUrl = uri.toString();
}
}).addOnFailureListener(new OnFailureListener() {
@Override
public void onFailure(@NonNull Exception exception) {
}
});
}
});
