用到的服务器端接口：

 1     [Route("api/[controller]/[action]")]
 2     [ApiController]
 3     public class FirstController : ControllerBase
 4     {
 5 
 6         /******************************************下面是测试Get请求的相关方法***************************************************/
 7 
 8         #region 下面是测试Get请求的相关方法
 9         [HttpGet]
10         public string GetInfor1(string userName, string pwd)
11         {
12             return $"{userName}+{pwd}";
13         }
14 
15         [HttpGet]
16         public string GetInfor2([FromQuery]UserInfor model)
17         {
18             return $"{model.userName}+{model.pwd}";
19         }
20         [HttpGet]
21         //加上[FromQuery]也报错
22         public string GetInfor3([FromQuery]dynamic model)
23         {
24             return $"{model.userName}+{model.pwd}";
25         }
26 
27         #endregion
28 
29     }
30     [Route("api/[controller]/[action]")]
31     [ApiController]
32     public class ThirdController : Controller
33     {
34        [HttpGet]
35         public IActionResult GetInfor4(string userName, string pwd)
36         {
37             return Json(new
38             {
39                 userName,
40                 pwd
41             });
42         }
43     }
