我想创建一个s3 bucket，每当有文件上传到bucket中的"uploads"文件夹时，就会触发lambda函数。我想在aws中使用无服务器框架来创建这些资源。
我已经在"provider.s3"下定义了我的s3 bucket配置，然后我试图在functions.hello.events.bucket 下引用该bucket
然而，当我运行sls package时，我得到了以下错误
Serverless Error ----------------------------------------
MyS3Bucket - Bucket name must conform to pattern (?!^(d{1,3}.){3}d{1,3}$)(^(([a-z0-9]|[a-z0-9][a-z0-9-]*[a-z0-9]).)*([a-z0-9]|[a-z0-9][a-z0-9-]*[a-z0-9])$). Please check provider.s3.MyS3Bucket and/or s3 events of function "hello".

我的下一个尝试是在"resources"下定义s3 bucket，并在lambda触发器中使用bucket的引用。我仍然收到的警告信息
Serverless: Configuration warning at 'functions.hello.events[0].s3.bucket': should be string

创建一个自定义s3存储桶名称变量，例如
custom:
bucket: foo-thumbnails
并使用它事件
events:
- s3:
bucket: ${self:custom.bucket}
您应该使用您的bucket名称，而不是MyS3Bucket:
events:
- s3:
bucket: ${env:MY_BUCKET_NAME}
