步骤(常规方法)

1. 新建一个控制器--LarsController.cs

   using Microsoft.AspNetCore.Mvc;
   namespace Blog.Controller;
   public class LarsController:Controller      -----继承
   {public IActionResult Index(){return View();}
   }
   

2. 获取id

   // program.cs中默认值是idpublic IActionResult Index(int id)
   {return Content(id.ToString());
   }
   

3. 获取方法中的name

   public class Students
   {public string name{get;set;}=null!;     ----字符串需要=null!public int age{get;set;}
   }// 在LarsController中
   [HttpPost]
   public IActionResult Create([FromBody]Students stu)
   {return Content(stu.name);
   }//[FromBody]传递复杂数据
