无服务器框架 |如何在前缀路径中使用通配符 (*)

Question

我正在使用无服务器框架创建 S3 Lambda 触发器：

functions:
  profilePictureInput:
    handler: triggers/handler.profilePictureInput
    memorySize: 10240
    timeout: 25
    events:
      - s3:
          bucket: ${self:custom.mediaInputBucketName}
          existing: true
          event: s3:ObjectCreated:*
          rules:
            - prefix: private/*/profile-pictures

问题：是否可以在前缀路径中使用通配符？

我希望在对象键为 private/foo/profile-pictures 或 private/bar/profile-pictures 时触发 lambda。

上面的例子似乎不起作用（lambda 未触发）

不，你不能。

Because the wildcard asterisk character (*) is a valid character that can be used in object key names, Amazon S3 literally interprets the asterisk as a prefix or suffix filter. You can't use the wildcard character to represent multiple characters for the prefix or suffix object key name filter.

您必须将所有前缀值字符串注册到 S3 事件。对于您的情况，它将如下所示：

functions:
  profilePictureInput:
    handler: triggers/handler.profilePictureInput
    memorySize: 10240
    timeout: 25
    events:
      - s3:
          bucket: ${self:custom.mediaInputBucketName}
          existing: true
          event: s3:ObjectCreated:*
          rules:
            - prefix: private/foo/profile-pictures
            - prefix: private/bar/profile-pictures
