WCF Rest Webservice 在本地主机上工作，但在服务器上不起作用

Question

我正在实现 WCF Rest WebGet 服务，它以 json 格式返回数据。它在 localhost 和本地 IIS 上完美运行。

这就是我在 localhost 上调用 webservice 的方式：

http://localhost:59395/WallpaperService.svc/GetCategory?intId=1

但它在服务器上不起作用。

以下两种情况在服务器上不起作用：

(1)http://xyz.co.in/WallpaperService.svc

它给出以下错误：

"Endpoint not found. Please see the service help page for constructing valid requests to the service."

(2)http://xyz.co.in/WallpaperService.svc/GetCategory?intId=1

它给出以下错误： 未找到 HTTP 404 资源

Code Snippet:

1. IWallpaperServices.cs


    using System.Text;

    namespace AwesomeWallpapers
    {
        // NOTE: You can use the "Rename" command on the "Refactor" menu to change the interface name "IAndroidAppWCF" in both code and config file together.
        [ServiceContract]
        public interface IWallpaperService
        {
            [OperationContract]
            [WebGet(UriTemplate = "GetCategory?intId={intId}",ResponseFormat=WebMessageFormat.Json)]
            string GetCategory(int intId);
        }
    }


2. WallpaperService.svc

     <%@ ServiceHost Language="C#" 
                        Debug="true" 
                        Service="AwesomeWallpapers.WallpaperService" 
                        CodeBehind="WallpaperService.svc.cs" 
                        Factory="System.ServiceModel.Activation.WebServiceHostFactory"%>

3. WallpaperService.svc.cs

using AwesomeWallpapers.Controllers;
using AwesomeWallpapers.Models;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.Text;
using System.Web.Script.Serialization;

namespace AwesomeWallpapers
{    
    public class WallpaperService : IWallpaperService
    {
        public string GetCategory(int intId)
        {
            try
            {
                List<Category_GetAllResult> lstCategory = new List<Category_GetAllResult>();
                DataController objController = new DataController();
                lstCategory = objController.GetAllCategory(intId);
                if (lstCategory != null && lstCategory.Count > 0)
                {
                    JavaScriptSerializer js = new JavaScriptSerializer();
                    return js.Serialize(lstCategory);
                }
            }
            catch (Exception ex)
            {
                ErrorLog.Write(ex);
            }
            return string.Empty;
        }
    }
}

我在 Web.config 中尝试了不同的标签，但没有任何效果。

请提供帮助或提出任何想法。

如果需要任何其他信息，请告诉我。

Answer 1

您将地址指向 mex

<endpoint contract="IMetadataExchange" 
                      binding="mexHttpBinding" 
                      address="mex" />

所以试着把 mex 放在你的 url 上，比如：

http://xyz.co.in/WallpaperService.svc/mex
