Firebase存储允许删除文件 [英] Firebase Storage Allow Deleting Files

问题描述

我对用户上传图片具有以下规则，但是当前规则不允许删除文件。

I have the following rules for user post image uploads, however current rules don't allow file deletion.

如何修改规则以允许用户删除他的照片？

How can I modify the rules to allow user to delete his pictures?

请求变量上的什么属性表示请求已删除？

What property on request variable indicates that a request is DELETE?

  match /{uid}/posts/{pid}/{imageName} {
    allow read;
    allow write: if (uid == request.auth.uid)
        && ((
            ((imageName == "pic.jpg") || (imageName == "pic.png") || (imageName == "pic.gif"))
            && (request.resource.size < 5 * 1024 * 1024)
            && (request.resource.contentType.matches('image/.*')) 
      ));
  }

是否有这样的东西？：

request.method == "DELETE"

我在文档中找不到任何内容。

I can't find anything in the documentation.

推荐答案

找到了它：

request.resource == null

嘿，Firebase开发人员，这应该在文档中！

Hey, Firebase devs, this should be in the docs!
