我正在尝试设置一个规则,在firebase中进行存储,只有经过身份验证的用户才能编写名为avatar的头像图像
这是firebase docs示例:
// Grants a user access to a node matching their user ID
service firebase.storage {
match /b/{bucket}/o {
// Files look like: "user/<UID>/path/to/file.txt"
match /user/{userId}/{allPaths=**} {
allow read, write: if request.auth.uid == userId;
}
}
}
这些是我在storage.rules文件中定义的规则:
service firebase.storage {
match /b/{bucket}/o {
match /{allPaths=**} {
allow read, write: if request.auth != null;
}
match /images/{allPaths=**} {
allow write: if request.resource.size < 5 * 1024 * 1024
&& request.resource.contentType.matches("image/.*")
&& request.resource.contentType == resource.contentType
}
match /images/user-{userId}/avatar.* {
allow read;
allow write: if request.auth.uid == userId;
}
}
}
当我部署抛出的错误是
[E] 13:25 - 意外的'userId'
我在文档中找不到任何其他内容,告诉我如何定义此userId。文档指定它,我做错了什么?
答案 0 :(得分:4)
与这两位评论者一样,语法不允许带“ -
的”文件夹“所以你必须选择像
这样的结构/images/user/{userId}
制定规则:
match /images/user/{userId}/avatar.* {
allow read;
allow write: if request.auth.uid == userId;
}
