Api Gateway将空参数发送到AWS Lambda [英] Api Gateway sends empty parameters to AWS lambda

问题描述

我正在尝试从API网关向AWS Lambda函数发送一些参数，问题是网关将所有空参数发送到lambda，因此失败.我查看了我所知道的配置，虽然数量不多，但我无法解决它.

I am trying to send some parameters to an AWS Lambda function from API Gateway, the problem is that Gateway sends all the empty parameters to the lambda, so it fails. I have reviewed the configurations that I know, which are not many, but I have not been able to solve it.

这是我的请求正文:

{
      "functionName": "register",
      "name": "camilo",
      "nick": "kmilo",
      "email": "[e-mail]",
      "phone": "555555",
      "birthdate": "29-09",
      "password": "000000"
    }

和映射模板:

 {
  "functionName":"$input.params('functionName')",
  "name":"$input.params('name')",
  "nick": "$input.params('nick')",
  "email": "$input.params('email')",
  "phone": "$input.params('phone')",
  "birthdate": "$input.params('birthdate')",
  "password": "$input.params('password')"
}

当我直接对其进行测试时，lambda函数可以正常工作，因此我认为问题出在API网关中

The lambda function works correctly when I test them directly, so I assume the problem is in API Gateway

推荐答案

{
    "functionName" = $input.json('$.functionName');
    "name":"$input.json('$.name')"
    //try for other body parameters as well.
}
