Question

我已按照以下链接在我的项目中创建启用了ajax的服务 https://msdn.microsoft.com/en-us/library/bb924552(v=vs.110).aspx

我的Asp.Net网络表单项目在不同的文件夹中有多个表单。 admin文件夹包含管理表单。我从admin文件夹创建了wcf服务，代码如下

namespace App.secure.Admin
{
    [ServiceContract(Namespace = "App.secure.Admin")]
    [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
    public class Admin
    {
        [OperationContract]
        public string updateComp(string city, string desc )
        {

在我的webform中，我无法添加单独的ScriptManager，因为我已经在表单中使用了ToolkitScriptManager。

我已添加服务参考，如下所示

 <ajx:ToolkitScriptManager runat="server" ID="sm1">
        <Services>
            <asp:ServiceReference Path="Admin.svc" />
        </Services>
    </ajx:ToolkitScriptManager>

当我尝试调用wcf服务调用时，它无法在wcf服务中实例化该类

 function UpdateStudent(e) {
       city = $("#spnCity").text();
       desc = $("#txtDescEd").val();
       var service = new App.secure.Admin.Admin();
       service.updateComp(city,  desc);
   }

当我运行应用程序时

Unhandled exception in http://localhost/secure/Admin/Add.aspx
0x800a1391 - JavaScript runtime error: 'App' is undefined

我已经尝试将WCf服务移动到根文件夹并尝试调用它，但是它给出了同样的错误。

add.aspx.cs文件，我正在使用

namespace App.secure
{
    public partial class Add : System.Web.UI.Page

web.config：

<system.serviceModel>
        <behaviors>
            <endpointBehaviors>
                <behavior name="App.AdminSvcAspNetAjaxBehavior">
                    <enableWebScript />
                </behavior>
                <behavior name="App.secure.Admin.AdminAspNetAjaxBehavior">
                    <enableWebScript />
                </behavior>
            </endpointBehaviors>
        </behaviors> <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" /> 
        <services>
            <service name="App.AdminSvc">
                <endpoint address="" behaviorConfiguration="App.AdminSvcAspNetAjaxBehavior" binding="webHttpBinding" contract="App.AdminSvc" />
            </service>
            <service name="App.secure.Admin.Admin">
                <endpoint address="" behaviorConfiguration="App.secure.Admin.AdminAspNetAjaxBehavior" binding="webHttpBinding" contract="App.secure.Admin.Admin" />
            </service>
        </services>
    </system.serviceModel>
</configuration>

谢谢

您需要添加服务行为和其他mex端点才能获取svc元数据。

配置应如下所示：

<system.serviceModel>
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true"
      multipleSiteBindingsEnabled="true" />
    <behaviors>
      <endpointBehaviors>
          <behavior name="AspNetAjaxBehavior">
          <enableWebScript />
        </behavior>
        <behavior name="Call_WCF_WebService_REST_With_jQuery.service.AjaxServiceAspNetAjaxBehavior">
          <enableWebScript />                   
        </behavior>
      </endpointBehaviors>
      <serviceBehaviors>
                <behavior name="MyAjaxSvcBehaviour">
                    <serviceMetadata httpGetEnabled="true" />
                    <serviceDebug includeExceptionDetailInFaults="true" />
                </behavior>
      </serviceBehaviors>
    </behaviors>
    <services>
      <service name="Call_WCF_WebService_REST_With_jQuery.service.AjaxService" behaviorConfiguration="MyAjaxSvcBehaviour">
        <endpoint address="" behaviorConfiguration="Call_WCF_WebService_REST_With_jQuery.service.AjaxServiceAspNetAjaxBehavior"
          binding="webHttpBinding" contract="Call_WCF_WebService_REST_With_jQuery.service.AjaxService" />
                <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
      </service>
    </services>
  </system.serviceModel>

HTML：

<script>
    var svc = new AjaxService();
    var res = svc.DoWork();
    var x = 0;
</script>

服务：

namespace Call_WCF_WebService_REST_With_jQuery.service
{
    [ServiceContract(Namespace = "")]
    [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
    public class AjaxService
    {
        // To use HTTP GET, add [WebGet] attribute. (Default ResponseFormat is WebMessageFormat.Json)
        // To create an operation that returns XML,
        //     add [WebGet(ResponseFormat=WebMessageFormat.Xml)],
        //     and include the following line in the operation body:
        //         WebOperationContext.Current.OutgoingResponse.ContentType = "text/xml";
        [OperationContract]
        public Person DoWork()
        {
            // Add your operation implementation here
            return new Person() { Age = 12, Name = "Jo" };
        }

        // Add more operations here and mark them with [OperationContract]
    }
}
