Use dynamic parameter Action is implemented in webapi Post invoke

Original: Use dynamic parameter Action is implemented in webapi Post invoke

1. controller / action / id webapi path in configuration, open the file [App_Start] - [WebApiConfig]

 

  config.Routes.MapHttpRoute(
                name: "DefaultApi",
                routeTemplate: "api/{controller}/{action}/{id}",
                defaults: new { id = RouteParameter.Optional }
            );

　

2. Use Direct [HttpPost] filter, add method implemented action:

[HttpPost]
// POST api/<controller>
public string AdminLogin(string userName,string passWord)
{
  return "";
}

　　Problems: the front end of the "type" was changed to "Post" way, in any case less than the acquisition method.

 

3. Solution one:

 ① adding transit object class, used to store parameters.

    public class AdminLogin
    {
        public string UserName { get; set; }

        public string PassWord { get; set; }
    }

② modify the action parameters.

   　　 [HttpPost]
        // POST api/<controller>
        public string AdminLogin([FromBody]AdminLogin adminLogin)
        {
           return adminLogin.UserName;
        }    

③ Method distal call:

      $.ajax({

            type: "POST", url: AdminApi.AdminLogin,
　　　　　　 data: {UserName："xxx",PassWord:"XXX"},
　　　　　　 success: function (data) {
           //处理方法

            }
        });

　　

　　

4. Solution two:

① modify parameters for the action and dynamic method call:

      [HttpPost]
        // POST api/<controller>
        public string AdminLogin([FromBody]dynamic adminLogin)
        {
            string userName = adminLogin.UserName;
            string passWord = adminLogin.PassWord;
            return  userName;
        }

② modify the front invocation:

        UserName {obj = var: username, PassWord: password}; 

        // call api authentication method 
        $ .ajax ({ 

            type: "the POST", URL: AdminApi.AdminLogin, Data: the JSON.stringify (obj), contentType: "file application / JSON ", 
　　　　　　 Success: function (Data) { 
             // implementation internal 
            } 
        });
