颤振Firebase-与firebase_auth一起使用firebase_storage [英] Flutter & Firebase - using firebase_storage along with firebase_auth

问题描述

使用firebase软件包: https://pub.dartlang.org/packages/firebase_auth https://pub.dartlang.org/packages/firebase_storage

Working with the firebase packages: https://pub.dartlang.org/packages/firebase_auth https://pub.dartlang.org/packages/firebase_storage

我可以使用firebase_auth登录到firebase，并且在那里一切正常，但是当我使用firebase_storage软件包上传文件时，访问被拒绝，我必须进入firebase并将权限设置为:

I can sign into firebase using firebase_auth, and everything works great there, but when I use the firebase_storage package to upload a file I get access denied and I have to go into firebase and set the permissions to:

service firebase.storage {
match /b/{bucket}/o {
match /{allPaths=**} {
  allow read, write;//: if request.auth != null;
   }
 }
}

这对于使用身份验证的应用程序来说不是理想的选择，我如何告诉firebase_storage软件包已通过firebase_auth软件包进行了身份验证?

This is not ideal for an application that uses authentication, how do I tell the firebase_storage package that I am authenticated via the firebase_auth package?

推荐答案

您应该没有这个问题，我分享了一个对我有用的代码.

You should not have that problem, I share a code that works for me.

Future<Null> ensureLoggedIn() async {
  FirebaseUser firebaseUser = await auth.currentUser();
  assert(firebaseUser != null);
  assert(!firebaseUser.isAnonymous);
}

Future<String> uploadFile(File file) async {
    assert(file != null);
    await ensureLoggedIn();
    int random = new Random().nextInt(100000);
    String _instance = '/files/image_$random.jpg';

    StorageReference ref = FirebaseStorage.instance.ref().child(_instance);
    StorageUploadTask uploadTask = ref.putFile(file);

    final Uri downloadUrl = (await uploadTask.future).downloadUrl;

    return downloadUrl.toString();
  }
