WCF Rest Web服务在localhost上运行，但在服务器上不运行

Question

I am implementing WCF Rest WebGet service which returns data in json format. It perfectly works on localhost and local IIS.

This is how I call webservice on localhost:

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

But it does not work on server.

Below two scenarios on server does not work:

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

It gives below error:

"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

It gives below error: HTTP 404 Resource not found

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;
        }
    }
}

I tried different tags in Web.config but nothing works.

Please help or suggest any ideas.

Let me know if any additional information is required.

Answer 1

You're pointing the address to mex

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

So try put mex at the of your url, like:

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