$.ajax({
    url: 'api/products',type: 'POST',data: { Id: 2012,Name: 'test',Category: 'My Category',Price: 99.5 },dataType: 'json',success: function (data) {
        alert(data);
    }
});

但它不工作怎么做？

$.ajax({
    url: 'api/products',data: JSON.stringify({ Id: 2012,Price: 99.5 }),success: function (data) {
        alert(data);
    }
});

$.ajax({
            url: url,dataType: 'json',type: 'Post',data: {token:"4",Feed:{"id":0,"message":"Hello World","userId":4} }
        });

服务器端Web API：

[HttpPost]
 public HttpResponseMessage Post(string token,Feed Feed)
 {
    /* Some code */

    return new HttpResponseMessage(HttpStatusCode.Created);
 }

Error Code 404: {“message”:”No HTTP resource was found that matches
the request URI ‘localhost:8080/api/Feed’.”,”messageDetail”:”No action
was found on the controller ‘Feed’ that matches the request.”}

为什么我收到此错误以及为什么我无法将多个参数POST到我的API？

public class Myviewmodel
{
    public string Token { get; set; }
    public Feed Feed { get; set; }
}

您的控制器操作将作为参数：

[HttpPost]
public HttpResponseMessage Post(Myviewmodel model)
{
    /* Some code */

    return new HttpResponseMessage(HttpStatusCode.Created);
}

最后调整你的jQuery调用将其作为JSON发送：

$.ajax({
    url: url,type: 'POST',contentType: 'application/json',data: JSON.stringify({
        token: '4',Feed: {
            id: 0,message: 'Hello World',userId: 4
        } 
    })
});

AJAX调用需要注意的重要事项：

>将请求contentType设置为application / json>将数据包装在JSON.stringify函数中,以有效地将javascript对象转换为JSON字符串>删除无用的dataType：’json’参数. jQuery将自动使用服务器发送的Content-Type响应头来推断如何解析传递给成功回调的结果.

< a href =“#”onclick =“编辑(@Interest);”>编辑< / a>

我在哪里

@ {string Interest =“”}

<a href="#" onclick="Edit('@Interest');">edit</a>

<% Html.RenderPartial("Details",Model.test,new ViewDataDictionary { { "labelName","Values1" },{"header","Header1"},{"header2","Header2"}}); %>

代码,我有错误信息

) missing.

怎么了？

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<IEnumerable<MvcUI.Models.Label>>" %>

 <%var label = ViewData["labelName"];%>
 <%int count = 0; %>


            <%if (Model!=null) {%>           
               <% foreach (var model in Model){ %>     


                    <%if (!String.IsNullOrEmpty(model.Name))                   
                   {%>
                    <li>
                          <%: Html.Hidden((label)+".Index",count.ToString())%>
                          <%: Html.TextBox((label)+"[" + (count) + "].Name",model.Name,new {})%>
                          <%: Html.Hidden((label)+"[" + (count++) + "].ID",model.ID,new {})%>
                        <input type="button" value = "Delete"/>
                    </li>
                    <%}
                     %>
                 <%} %>

                <% } %>

public class MyModel
{
    public string Test { get; set; }
    public string LabelName { get; set; }
    public string Header { get; set; }
    public string Header2 { get; set; }
}

然后简单地说：

<% Html.RenderPartial("Details",Model); %>

除此之外,你的语法没有任何问题.你得到的错误来自其他地方：

<% Html.RenderPartial(
    "Details",new ViewDataDictionary { 
        { "labelName",{ "header","Header1" },{ "header2","Header2" }
    }
); %>

更新：

现在您已经展示了代码,让我建议您使用编辑器模板更清晰的方法.

首先定义一个模型：

public class MyModel
{
    public IEnumerable<Label> Labels { get; set; }
}

public class Label
{
    public string ID { get; set; }
    public string Name { get; set; }
}

然后一个控制器将填充此模型：

public class HomeController : Controller
{
    public ActionResult Index()
    {
        var model = new MyModel
        {
            Labels = new[] 
            {
                new Label { ID = "l1",Name = "Label 1" },new Label { ID = "l2",Name = "Label 2" },new Label { ID = "l3",Name = "Label 3" }
            }
        };
        return View(model);
    }
}

然后是视图(〜/ Views / Home / Index.aspx)：

<%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<SomeNs.Models.MyModel>" %>
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
    <ul>
        <%: Html.EditorFor(x => x.Labels) %>
    </ul>
</asp:Content>

最后是编辑器模板(〜/ Views / Home / EditorTemplates / Label.ascx)：

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<SomeNs.Models.Label>" %>
<li>
    <%: Html.HiddenFor(x => x.ID) %>
    <%: Html.TextBoxFor(x => x.Name) %>
    <input type="button" value="Delete" />
</li>

如您所见,使用编辑器模板,您不再需要担心命名输入,维护和增加索引,编写循环,所有这些容易出错的事情都由框架自动处理.

        [AcceptVerbs(HttpVerbs.Post)]
        public JsonResult PostMoreData(DataContracts.Address address,DataContracts.GeoLocation geoLocation)
        {
            return Json("test");
        }

where DataContracts.Address and DataContracts.GeoLocation are complex types.

从我的视图我试图使用jQuery发布如下：

        function PostMoreData() {

            var JsonAddress = {

                "Building": $('Building').val(),"UnitNumber": $('UnitNumber').val(),"StreetNumber": $('StreetNumber').val(),"StreetName": $('StreetName').val(),"StreetType": $('StreetType').val(),"Suburb": $('Suburb').val(),"State": $('State').val(),"Postcode": $('Postcode').val(),"MonthsAtAddress": $('MonthsAtAddress').val()

            };

            var JsonGeoLocation = {
                "Latitude": $('Latitude').val(),"Longitude": $('Longitude').val()
            };


            jQuery.post("/AddressValidation/PostMoreData",{address: JsonAddress,geoLocation: JsonGeoLocation},function(data,textStatus) {
                if (textStatus == "success") {
                    var result = eval(data);
                    if (result.length > 0) {
                        alert(result);
                    }
                }
            },"json");
        } 

但是,在控制器上,我得到空值.

它可以工作,如果我的控制器只需要一个参数,我只发布一个对象.

        [AcceptVerbs(HttpVerbs.Post)]
        public JsonResult PostMoreData(DataContracts.Address address)
        {
            return Json("test");
        }

        function PostMoreData() {

            var JsonAddress = {

                "Building": $('Building').val(),"MonthsAtAddress": $('MonthsAtAddress').val()

            };


            jQuery.post("/AddressValidation/PostMoreData",JsonAddress,"json");
        } 

任何想法如何我可以发布多个对象？

address=[object]&geoLocation=[object]

另一个工作示例不包含任何子对象,因此它是直接翻译的,如下所示：

Building=value&UnitNumber=value&...&MonthsAtAddress=value

最简单的解决方法是使参数映射平坦,每个键都以“地址”为前缀.或’GeoLocation.’,取决于.
