我有一个自己托管WCF服务的控制台应用程序。当用户访问asp.net应用程序并单击页面上的按钮时,如何编写脚本以将此自托管WCF服务称为本地托管的服务。我想我的剧本有问题,请帮忙

namespace SelfHost
{
  [ServiceContract]
  public interface IHelloWorldService
  {
      [OperationContract]
      string SayHello(string name);
  }

  [AspNetCompatibilityRequirements(RequirementsMode =     AspNetCompatibilityRequirementsMode.Allowed)]
  public class HelloWorldService : IHelloWorldService
  {
    public string SayHello(string name)
    {
        return string.Format("Hello, {0}", name);
    }
}

class Program
{
    static void Main(string[] args)
    {
        Uri baseAddress = new Uri("http://127.0.0.1/hello");

        // Create the ServiceHost.
        using (ServiceHost host = new ServiceHost(typeof(HelloWorldService), baseAddress))
        {
            // Enable metadata publishing.
            ServiceMetadataBehavior smb = new ServiceMetadataBehavior();
            smb.HttpGetEnabled = true;
            smb.MetadataExporter.PolicyVersion = PolicyVersion.Policy15;
            host.Description.Behaviors.Add(smb);

            // Open the ServiceHost to start listening for messages. Since
            // no endpoints are explicitly configured, the runtime will create
            // one endpoint per base address for each service contract implemented
            // by the service.
            host.Open();

            Console.WriteLine("The service is ready at {0}", baseAddress);
            Console.WriteLine("Press <Enter> to stop the service.");
            Console.ReadLine();

            // Close the ServiceHost.
            host.Close();
        }
    }
}
调用服务的脚本

<script type="text/javascript">
    function invokeService() {
        $(document).ready(function () {
            var userName = " test";

            $.ajax({
                type: "POST",
                async: "false",
                url: "http://127.0.0.1:8080/hello",
                data: "{'name':'" + userName + "'}",
                contentType: "application/json; charset=utf-8",
                dataType: "json",
                processData: true,
                method: "SayHello",
                success: function (result) {
                    AjaxSucceeded(result);
                },
                error: function (retult) {
                    AjaxFailed(result);
                }
            });
        });
    }

不要希望以这种方式使用jquery调用WCF服务

最大的问题是您正在公开一个Soap服务,并试图使用一个类似rest的客户端来调用它

自.NET3.5以来,WCF允许您向非SOAP端点公开WCF服务操作。您必须以这种方式公开您的服务,才能使用Jquery来使用它

MSDN ie的起点,几年前有一个很好的介绍

一个非常简单的例子是没有任何配置

[ServiceContract]
public interface IService
{
    [OperationContract]
    [WebGet(BodyStyle=WebMessageBodyStyle.Bare, RequestFormat=WebMessageFormat.Json, ResponseFormat=WebMessageFormat.Json)]
    string EchoWithGet(string s);

    [OperationContract]
    [WebInvoke(BodyStyle=WebMessageBodyStyle.Bare, RequestFormat=WebMessageFormat.Json, ResponseFormat=WebMessageFormat.Json)]
    string EchoWithPost(string s);
}

public class Service : IService
{
    public string EchoWithGet(string s)
    {
        return "You said " + s;
    }

    public string EchoWithPost(string s)
    {
        return "You said " + s;
    }
}

class Program
{
    static void Main(string[] args)
    {
        WebServiceHost host = new WebServiceHost(typeof(Service), new Uri("http://localhost:8000/"));
        ServiceEndpoint ep = host.AddServiceEndpoint(typeof(IService), new WebHttpBinding(), "");
        ServiceDebugBehavior sdb = host.Description.Behaviors.Find<ServiceDebugBehavior>();
        sdb.HttpHelpPageEnabled = false;
        host.Open();
        Console.WriteLine("Service is running");
        Console.WriteLine("Press enter to quit...");
        Console.ReadLine();
        host.Close();
    }
}

刚刚发现不允许通过脚本进行跨域调用。所以另一种方法是使用命令行应用程序或控制台文件来调用wcf服务。然后在注册表中注册此应用程序。然后从脚本启动应用程序。

我们需要查看您的自托管服务的配置文件!所有有趣的东西,比如绑定和行为,都是在这里配置的——如果没有这些,我们就无能为力,真的。。。但是调用自托管WCF服务与调用IIS托管的WCF服务没有什么不同,真的-只要获得正确的WCF地址、绑定和合同的ABC,您就可以开始了!当您尝试调用该服务时,控制台应用程序是否正在运行?从WCF服务可以看出,您正在使用BasicHttpBinding公开SOAP服务。如果您想从JQuery/Ajax调用您的服务,而不是在JQuery/Ajax中构建完整的SOAP消息,那么最好使用chrome提供的WebHttpBindingDebug公开WCF服务,因为在本地脚本上调用自托管服务似乎是跨域的,我将尝试解决这个问题。
