Question

我是WCF服务的新手。我只想学习带有$ .ajax调用的WCF，因此创建了一个测试应用程序，它有两个项目1.Wcf服务的WcfService1项目和另一个使用该服务的客户端asp.net应用程序。 当我尝试对服务错误404（未找到）进行ajax调用时显示 当我运行WCF服务时，一切正常。即使我尝试从客户端C＃文件中调用它，一切都还可以。。客户的代码是

<body>
<form id="form1" runat="server">
<div>
Enter a number here : &nbsp &nbsp<asp:TextBox runat="server" ID="txtbox"></asp:TextBox><br /><br />
<asp:Button runat="server" ID="btnClick" OnClick="btnClick_Click" Text="ClickMe"/>
</div>
</form>
<script type="text/javascript">
    $('#txtbox').on("keyup", function () {
        debugger;
        var txt = parseInt($(this).val());
        $.ajax({
            url: "http://localhost:2393/Service1.svc/GetData",
            type: "POST",
            contentType: "application/json",
            dataType:"jsonp",
            data: JSON.stringify({ value: txt }),
            success: function (data) {
                alert(data);
                console.log(data.d);
            }
        });
    });
</script>
</body>

我对WcfService进行了简单的ajax调用，它只是回显输入的数字。我的客户端Web.config文件是

<configuration>
<system.web>
    <compilation debug="true" targetFramework="4.0" />
</system.web>

<system.serviceModel>
    <bindings>
        <basicHttpBinding>
            <binding name="BasicHttpBinding_IService1" />
        </basicHttpBinding>
    </bindings>
    <client>
        <endpoint address="http://localhost:2393/Service1.svc" binding="basicHttpBinding"
            bindingConfiguration="BasicHttpBinding_IService1" contract="ServiceReference1.IService1"
            name="BasicHttpBinding_IService1" />
    </client>
</system.serviceModel>
</configuration>

我的WcfService web.config，接口（契约）后跟WcfService实现如下

<configuration>
<system.web>
<compilation debug="true" targetFramework="4.0" />
 </system.web>
  <system.serviceModel>
<bindings />
<client />
<behaviors>
  <serviceBehaviors>
    <behavior>
      <!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
      <serviceMetadata httpGetEnabled="true"/>
      <!-- To receive exception details in faults for debugging purposes, set the value below to true.  Set to false before deployment to avoid disclosing exception information -->
      <serviceDebug includeExceptionDetailInFaults="false"/>
    </behavior>
  </serviceBehaviors>
</behaviors>
<serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
</system.serviceModel>
<system.webServer>
<modules runAllManagedModulesForAllRequests="true"/>
</system.webServer>  
</configuration>

服务合同

namespace WcfService1
{
  [ServiceContract]
   public interface IService1
  {
    [OperationContract]
    [WebGet(UriTemplate = "/GetData/{value}",
   ResponseFormat = WebMessageFormat.Json)] 
    string GetData(int value);
  }   
}

服务实施

namespace WcfService1
{    
public class Service1 : IService1
{
    public string GetData(int value)
    {
        return string.Format("You entered: {0}", value);
    }
}
}

如果我错了，请指导我。提前谢谢。
