用户无权访问此对象。带有存储firebase
问题描述 投票：1回答：2
我正在制作一个类似于社交媒体应用程序的android应用程序但是当我尝试从图库或摄像机中放入图像作为配置文件或封面时，会发生此问题。
我希望用户从他的画廊中选择照片或使用相机拍摄新照片，然后将图像上传到Firebase存储。
用户无权使用Firebase存储访问此对象。
有我的权限..
<uses-permission android:name="android.permission.VIBRATE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

搜索后，我找到了解决方案..我在Firebase中的规则不正确..
我们应该那样做..
service firebase.storage
{ match /b/learno-fc8fc.appspot.com/o
{ match /{allPaths=**}
{ // Allow access by all users
allow read, write; }
