WebAPI调用的问题

[dengyi425]

      $.ajax({
            type: 'POST',
            url: 'api/login/UserLogin?LoginName=test&LoginPwd=123',
            data: “”,
            dataType: 'json',
            async: false,
            cache: false,
            success: function (data, textStatus) {

调用WebAPI登录的方法，传参的时候只能在URL地址上接上，能不能向下面一样？

        $.ajax({
            type: 'POST',
            url: 'api/login/UserLogin',
            data: { LoginName: "test", LoginPwd: "123" },
            dataType: 'json',
            async: false,
            cache: false,
            success: function (data, textStatus) {}

用这种方法提示
POST http://localhost:52655/api/login 404 Not Found

应该怎么写？

[dengyi425]

 public class RouteConfig
    {
        public static void RegisterRoutes(RouteCollection routes)
        {
            routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

            routes.MapRoute(
                name: "Default",
                url: "{controller}/{action}/{id}",
                defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
            );
        }
    }

这是mvc的route，不是webapi的

[dengyi425]

            config.Routes.MapHttpRoute(
             name: "Api_Get",
             routeTemplate: "api/{controller}/{action}/{id}",
             defaults: new { id = RouteParameter.Optional, action = "Get" },
             constraints: new { httpMethod = new HttpMethodConstraint("GET") }
            );

            config.Routes.MapHttpRoute(
             name: "Api_Post",
             routeTemplate: "api/{controller}/{action}/{id}",
             defaults: new { id = RouteParameter.Optional, action = "Post" },
             constraints: new { httpMethod = new HttpMethodConstraint("POST") }
            );

你这样设置有啥意思呢？还不如去除掉约束和action呢……而且你的约束在MVC5下面不对，MVC5下面是new HttpMethodConstraint(new HttpMethod("POST"))

唉，我猜测出你的问题了，你的userlogin方法是不是有两个参数？要么你组合成一个实体，要么你在这两个参数前面都加[FromBody]特性

这是你route的问题，你将你的route配置写出来呢
