AWS Lambda代理Swagger模板集成

Question

我正在尝试设置Swagger模板来调用我的一体化Lambda函数。

假设在processlambda下有两个"functions"。 这是否是正确的OpenAPI 3.0模板，还是我需要专门配置请求类型和响应类型？

         "variables": {
            "basePath": {
              "default": "/Process"
            }
         }
      }
   ]
}

我尚未测试过这个功能，但C#函数代码使用了APIGateway响应/请求标准的aws对象。

作为替代方案，您可以使用的一个好路径是配置API Gateway（指向AWS Lambda），然后从API Gateway配置生成您的openapi规范，然后生成您的c#客户端。

在配置API Gateway之后，您可以执行以下步骤：

第1步/2步) 运行get-export，例如:

aws apoigateway get-export 
  --rest-api-id 'idfromapigateway-grab-inside-awsdashboard' 
  --stage-namem 'stage-grab-inside-awsdashboard' 
  --export-type 'swagger' outputfile-with-openapispec-generated-step1.json

第二步（2 of 2）：生成客户端，例如：

nswag swagger2csclient /input:outputfile-with-openapispec-generated-step1.json
  /classname:SpecifyYourCSharpClassName
  /namespace:SpecifyYourCSharpNamespace
  /output:SpecifyYourCSharpFile

第二步的结果会生成 C# 类，可用于集成测试。
