Question

我试图使用jquery从MVC（razor）调用我的WCF方法然后我收到错误

请求网址：localhost：8377 / Service / ajaxServiceEstimate.svc / Location
请求方法：POST状态
代码：HTTP / 1.1 404 Not Found

网络配置

    <system.serviceModel>
    <services>
      <service name="Estimate.Service.ajaxServiceEstimate" behaviorConfiguration="Estimate.Service.ajaxServiceEstimate" >
        <endpoint address="" behaviorConfiguration="Estimate.Service.ajaxServiceEstimateAspNetAjaxBehavior"
          binding="webHttpBinding" contract="Estimate.Service.ajaxServiceEstimate" />
        <endpoint contract="IMetadataExchange" binding="mexHttpBinding" address="mex" />
      </service>
    </services>

    <behaviors>
      <endpointBehaviors>
        <behavior name="Estimate.Service.ajaxServiceEstimateAspNetAjaxBehavior">
          <enableWebScript />
        </behavior>
      </endpointBehaviors>
      <serviceBehaviors>
        <behavior name="Estimate.Service.ajaxServiceEstimate" >
         <serviceMetadata httpGetEnabled="true" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>

服务代码

    namespace Estimate.Service
{
    [ServiceBehavior(IncludeExceptionDetailInFaults = true)]
    [ServiceContract(Namespace = "")]
    [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
    public class ajaxServiceEstimate
    {
        [OperationContract]
        public void DoWork()
        {
            // Add your operation implementation here
            return;
        }

        // Add more operations here and mark them with [OperationContract]
        [OperationContract]
        [WebInvoke(Method = "GET", ResponseFormat = WebMessageFormat.Json)]
        public string Location()
        {
            return "anurag";
        }
    }
}

jQuery代码：

    <script src="~/Scripts/jquery-1.7.1.min.js" type="text/javascript"></script>
<script type="text/javascript">
    function GetTeamData() {
        $.ajax(
        {
            async: true,
            type: "POST",
            contentType: "application/json; charset=utf-8",
            url: "http://localhost:8377/Service/ajaxServiceEstimate.svc/Location",
            dataType: "json",
            data: '{}',
            success: function (content) {
                DisplayRun(map, content);
            }
        });
    }
</script>
<div>
    <input id="btnSave" type="button" value="Save" onclick="GetTeamData();" />
    <div id="divOutput"></div>
</div>

Answer 1

是否有必要使用WCF。更好地使用WebAPI它们非常简单快速。如果卡在绑定中，WCF会产生问题。如果可以，请尝试使用WebAPI。

Answer 2

您应该检查路由文件，并将Services文件夹设置为忽略。还要添加要接受的文件类型。

            routes.IgnoreRoute("{resource}.svc/{*pathInfo}");
            routes.IgnoreRoute("{folder}/{*pathInfo}", new { folder = "Service" });
