用jmespath按日期排序 [英] Sort by date with jmespath

问题描述

具有json输出，如:

With a json output like :

{
   "Functions":[
      {
         "CodeSha256":"7NBvXXacp9x3aK3cKaI=",
         "FunctionName":"function_1",
         "FunctionArn":"arn:aws:lambda:eu-west-1:1111:function:function_1",
         "LastModified":"2015-02-09T11:35:31.084+0000"
      },
      {
         "CodeSha256":"7NBvXXacKaI=",
         "FunctionName":"function_3",
         "FunctionArn":"arn:aws:lambda:eu-west-1:1111:function:function_3",
         "LastModified":"2015-03-09T11:35:31.084+0000"
      },
      {
         "CodeSha256":"7NBvXXacaK3cKaI=",
         "FunctionName":"function_2",
         "FunctionArn":"arn:aws:lambda:eu-west-1:1111:function:function_2",
         "LastModified":"2015-02-11T11:35:31.084+0000"
      }
   ]
}

如何返回按LastModified排序的两个最新函数?

How can I return the two most recent Functions sorted by LastModified?

推荐答案

您需要先使用reverse和sort_by.然后仅对两个记录添加[:2]:

You need to use reverse and sort_by first. Then add [:2] for only two record :

aws lambda list-functions --query "reverse(sort_by(Functions, &LastModified))[:2]"
