【中文标题】用户无权访问此对象。带储藏火库【英文标题】：User does not have permission to access this object . with storage firebase 【发布时间】：2020-08-09 13:25:32 【问题描述】：我正在制作一个类似于社交媒体应用程序的安卓应用程序 但是当我尝试从图库或相机中放置图像以进行配置或覆盖时，会出现此问题。
我希望用户从他的图库中选择一张照片或使用相机拍摄一张新照片，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" />

FIrebase 安全规则：
service firebase.storage
match /b/learno-fc8fc.appspot.com/o
// Allow access by all users
allow read, write;
问题的屏幕截图。
【问题讨论】：
是的，问题出在我的规则中，你应该这样设置..service firebase.storage match /b/learno-fc8fc.appspot.com/o match /allPaths=** // Allow access by all users allow read, write;
【参考方案1】：
搜索后我找到了解决方案.. 我在 Firebase 中的规则不对..
我们应该这样做..
service firebase.storage
match /b/learno-fc8fc.appspot.com/o
match /allPaths=**
// Allow access by all users
allow read, write;
【讨论】：
【参考方案2】：如果正确，请您交叉检查您的存储桶名称。
