如何在Cloudformation中指定JSON格式的字符串? [英] How to specify JSON-formatted string in Cloudformation?

问题描述

我在CloudFormation模板上拥有以下资源，可从AWS文档中创建运行Lambda函数的规则:

I have the following resource on my CloudFormation template to create a rule to run a Lambda function, from the AWS documentation:

  "ScheduledRule": {
    "Type": "AWS::Events::Rule",
    "Properties": {
    "Description": "ScheduledRule",
    "ScheduleExpression": "rate(5 minutes)",
    "State": "ENABLED",
    "Targets": [{
      "Arn": { "Fn::GetAtt": ["myLambda", "Arn"] },
      "Id": "TargetFunctionV1"
    }]
    }
  }

我想指定输入:

{
  "Arn" : String,
  "Id" : String,
  "Input" : String,
  "InputPath" : String
}

and Input是传递给目标的JSON格式的文本字符串.此值将覆盖匹配的事件.

and Input is a JSON-formatted text string that is passed to the target. This value overrides the matched event.

我希望JSON格式的文本为:

I would like my JSON formatted text to be:

{
  "mykey1": "Some Value"
}

输入时，我不知道如何在输入中指定它:

I do not know how to specify it in the Input, when I put:

  "ScheduledRule": {
    "Type": "AWS::Events::Rule",
    "Properties": {
    "Description": "ScheduledRule",
    "ScheduleExpression": "rate(5 minutes)",
    "State": "ENABLED",
    "Targets": [{
      "Arn": { "Fn::GetAtt": ["myLambda", "Arn"] },
      "Id": "TargetFunctionV1",
      "Input": { "mykey1": "Some Value" }
    }]
    }
  }

我会收到错误消息:

Value of property Input must be of type String

我应该如何正确指定它?

How should I specify it correctly?

推荐答案

我自己找到了答案:

输入":"{\"test \":\"value11 \"，\"test2 \":\"value22 \"}"

"Input": "{ \"test\" : \"value11\", \"test2\" : \"value22\"}"

希望它对其他人有帮助.

Hope it helps someone else.

更新:

您基本上使用JSON.Stringify()的结果将字符串放入输入"字段.使用在线JSON.Stringify()，例如 https://onlinetexttools.com/json-stringify-text

You basically use the result of JSON.Stringify() to get the string into "Input" field. Use online JSON.Stringify() like https://onlinetexttools.com/json-stringify-text
