存储功能的 Firebase 权限 [英] Firebase permission for storage function

问题描述

我正在尝试使用以下方法在存储桶中的特定路径上触发我的功能:

I'm trying to trigger my function on specific path in storage bucket using:

exports.generateThumbnail = functions.storage.bucket("users").object().onChange(event => {});

当我尝试部署它时，控制台显示:

When I try to deploy it, console shows:

functions[generateThumbnail]: Deploy Error: Insufficient permissions to (re)configure a trigger (permission denied for bucket users). Please, give owner permissions to the editor role of the bucket and try again.

我该怎么做?我是否需要设置 IAM 或存储桶权限或其他什么?

How can I do that? Do I nedd to setup IAM or bucket permission or maybe something else?

推荐答案

看起来问题是您尝试引用名为users"的存储桶，而不是过滤对象前缀.

Looks like the issue is that you're trying to reference a bucket named "users" rather than filtering on an object prefix.

你想要的是:

exports.generateThumbnail = functions.storage.object().onChange(event => {
  if (object.name.match(/users//)) {
    // do whatever you want in the filtered expression!
  }
});

最终我们希望使前缀过滤可用，以便您可以执行 object("users")，但目前您必须像上面一样在您的函数中进行过滤.

Eventually we want to make prefix filtering available so you can do object("users"), but currently you have to filter in your function like above.
