lambda - 无法在 Serverless .net core web api 中映射 POST API 的请求参数

Question

我正在尝试在 Visual Studio Serverless Web api 项目中编写一些 api。我面临的问题是如何在 Post 请求中映射参数：

 [HttpPost]
 public async Task<IActionResult> Login([FromBody]LoginRequest request)
 {
  .......
 }

此 API 将托管在 API Gateway 上。如何操作 body 属性以便可以映射 LoginRequest 对象？

{
  **"body": "{\"test\":\"body\"}",  // map LoginRequest here ?**
  "resource": "/{proxy+}",
  "path": "/path/to/resource",
  "httpMethod": "POST",

}
