将复杂类型传递给 AWS API 网关端点

Question

我有一个 aws api 网关端点，我正在尝试使用Mock Lambda Test Tool命令进行测试。 aws api 网关端点需要一个具有 NoOFHours、AutoRecharge 属性的输入类型。 我将正文作为“body”传递：“{“NoOFHours”：51&“\AutoRecharge”：false}”，但 aws 框架抛出“错误反序列化输入 JSON 以键入 APIGatewayProxyRequest”错误。

应如何将复杂类型传递给 aws api 网关进行测试？

 public async Task<APIGatewayProxyResponse> CreatePaymentIntent(APIGatewayProxyRequest apiGatewayProxyRequest, ILambdaContext context)
      {

      }

public class CreatePaymentIntentInput
    {
        [JsonProperty(Required = Required.Always)]
        public int NoOFHours { get; set; }
        [JsonProperty(Required = Required.Always)]
        public bool AutoRecharge { get; set; }=false;
      }

Answer 1

我可以通过将"body"更改为"{'NoOFHours':51,'AutoRecharge':false}"来完成这项工作。
