这是我第一次使用无服务器框架，我的任务是用无服务器创建一个lambda、s3和dynamodb，然后调用lambda将其从s3转换到dynamo。我正在尝试获得一个由serverless生成的名称到我的S3中，以便在我的Lambda中使用它，但我没有运气。这是我的serveless.yml的样子：
service: fetch-file-and-store-in-s3
frameworkVersion: ">=1.1.0"
custom:
bucket:
Ref: Outputs.AttachmentsBucketName
provider:
name: aws
runtime: nodejs12.x
stage: dev
region: us-east-1
iamRoleStatements:
- Effect: Allow
Action:
- s3:PutObject
- s3:PutObjectAcl
Resource: "arn:aws:s3:::${self:custom.bucket.Ref}/*"
functions:
save:
handler: handler.save
environment:
BUCKET: ${self:custom.bucket.Ref}
resources:
# S3

缩进对于serverless.yml文件很重要。在本例中，AttachmentsBucket是一个资源，它应该在Resources下的子部分中有一个制表符空格，然后Type和Properties应该在资源名称：AttachmentsBucket中有一个制表符空格，而在提供的示例中实际上有两个制表符空格。CloudFormation将无法处理此特定资源，因为它无法识别具有正确名称和属性资源。
请参阅更新后的示例：
Resources:
AttachmentsBucket:
Type: AWS::S3::Bucket

# Set the CORS policy
