AWS Ruby SDK Cloudformation不会验证模板

遇到ruby Cloudformation问题时，我有一个超级简单的Cloudformation模板，它将使用AWS CLI验证并创建_堆栈，但在使用ruby SDK运行相同命令时失败

$ cat net.yml
AWSTemplateFormatVersion: '2010-09-09'

Resources:
  Vpc:
    Type: AWS::EC2::VPC
    Properties:
      CidrBlock: 10.0.0.0/16

无论我是否在

模板\u body

字段中使用

文件：//

，这都无关紧要。如果我将Ruby上传到S3，我可以让它使用相同的模板工作，但我不想这样做。以前有人遇到过此问题吗？

根据，模板体的值应为字符串

模板体（字符串）-包含模板体的结构，最小长度为1字节，最大长度为51200字节

因此，您只需读取文件并将其作为字符串传递给选项

irb(main):001:0> File.read('x.yml')
=> "Resources:\n        myvpc:\n                Type: AWS::EC2::VPC\n                
Properties: \n                        CidrBlock: String\n"
irb(main):002:0>


irb(main):038:0> cfn.validate_template({template_body: File.read('x.yml').to_s})
=> #<struct Aws::CloudFormation::Types::ValidateTemplateOutput parameters=[],
 description=nil, capabilities=[], capabilities_reason=nil, declared_transforms=[]>
irb(main):039:0>

irb（main）：001:0>File.read（'x.yml'）
=>“资源：\n myvpc:\n类型：AWS:：EC2:：VPC\n
属性：\n CidrBlock:字符串\n“

建议您通过btw退房，您会发现更多
