如何从Web应用程序调用Windows服务应用程序中托管的WCF服务？

我想从Web应用程序调用Windows服务应用程序中的方法。为此，我在Windows服务应用程序中托管了WCF服务。但是我不知道如何从Web应用程序中调用Windows服务应用程序中托管的WCF服务中的方法。

我能否知道是否可以从Web应用程序与托管在其中的WCF服务进行通信Windows服务应用程序以你称之为web api的方式？ （我尝试使用Angularjs调用WCF服务）

如果是这样，任何人都可以帮我一个例子。

我是学生并原谅我，如果我说的话事实错误。



我尝试过：



我的WCF服务代码



HelloService.cs

I wanted to call a method in a windows service application from a web application. To do so i hosted a WCF service in Windows service application. Yet I have no any idea, how to call a method in WCF service hosted in windows service application from web application.
can i know whether is it possible to communicate from web application to a WCF service hosted in windows service application in a way you call a web api? (I try to call the WCF service using Angularjs)
If so can anyone help me with an example.
I'm a student and forgive me if i'm stating facts wrong.

What I have tried:

My WCF service code

HelloService.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.Text;

namespace HelloService
{
    // NOTE: You can use the "Rename" command on the "Refactor" menu to change the class name "HelloService" in both code and config file together.
    
    public class HelloService : IHelloService
    {      
        
        public string GetMessage()
        {
            return "Hello ";
        }
    }
}

IHelloService.cs

IHelloService.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.Text;
using System.ServiceModel.Web;

namespace HelloService
{
    // NOTE: You can use the "Rename" command on the "Refactor" menu to change the interface name "IHelloService" in both code and config file together.
    [ServiceContract]
    public interface IHelloService
    {
        [OperationContract]
        [WebInvoke(Method = "GET", UriTemplate = "GetMessage",
      ResponseFormat = WebMessageFormat.Xml, RequestFormat = WebMessageFormat.Xml,
      BodyStyle = WebMessageBodyStyle.Bare)]
        string GetMessage();
    }
}

我的Windows服务应用程序代码



HelloWindowsService.cs

My Windows service application code

HelloWindowsService.cs

using System;
using System.Collections.Generic;

using System.Text;
using System.Threading.Tasks;
using System.ServiceModel;

namespace WindowsServiceHost
{
   
    public partial class HelloWindowsService : ServiceBase
    {
        ServiceHost host;
        public HelloWindowsService()
        {
            InitializeComponent();
        }

        protected override void OnStart(string[] args)
        {
            host = new ServiceHost(typeof(HelloService.HelloService));
            host.Open();
        }

        protected override void OnStop()
        {
            host.Close();
        }
    }
}
