Asp.net mvc 如何使用URL将param设置为FromURI?

Asp.net mvc 如何使用URL将param设置为FromURI?,asp.net-mvc,asp.net-web-api,routing,Asp.net Mvc,Asp.net Web Api,Routing,因此,我有以下控制: public class ItemQuery { public int storeID { get; set; } public int companyID { get; set; } public string itemName { get; set; } public string itemDescription { get; set; } public string itemPLU { get; set; } publi

因此,我有以下控制:

public class ItemQuery {
    public int storeID { get; set; }
    public int companyID { get; set; }
    public string itemName { get; set; }
    public string itemDescription { get; set; }
    public string itemPLU { get; set; }
    public string itemUPC { get; set; }
    public int supplierID { get; set; }
    public string partNumber { get; set; }
}
public class ItemController : ApiController {
    public List<Item> FindItem([FromUri]ItemQuery query) {
        return new List<Item>();
    }

}
它不工作,但给了我这个错误:

The requested resource does not support http method 'GET'.
我该怎么办?这是我的路线信息,我还没有更改任何内容:

    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 }
        );
    }

您尚未定义WebApi的路由


您拥有的
routes.MapRoute
是用于MVC的。要定义WebApi的路由,您需要使用
routes.MapHttpRoute

我认为您应该确保为Web Api使用System.Web.Http命名空间

然后将方法名称更改为
GetFindItem
或添加
HttpGet
属性,如下所示:

[HttpGet]
public List<Item> FindItem([FromUri]ItemQuery query){  //   }
http://localhost:43751/api/Item/?storeId=1&companyID=2&itemName=ABC&itemDescription=good&itemPLU=aa&itemUPC=dd&&supplierID=1&partNumber=number 
如果您使用Ajax调用Web API,下面是一个示例

Js文件

var data = {
    storeID: 1,
    companyID: 1,
    itemName: 'Test',
    itemDescription: 'Description',
    itemPLU: 'Test',
    itemUPC: 'Test',
    supplierID: 1,
    partNumber: 'Description',
};
$.getJSON('/api/Item', { query:data }, function() {
       alert("success");
});
var data = {
    storeID: 1,
    companyID: 1,
    itemName: 'Test',
    itemDescription: 'Description',
    itemPLU: 'Test',
    itemUPC: 'Test',
    supplierID: 1,
    partNumber: 'Description',
};
$.getJSON('/api/Item', { query:data }, function() {
       alert("success");
});
