【问题描述】：

您好，目前我正致力于在浏览器中以 xml 格式显示服务。

但是，它显示一个空白页面，有没有解释为什么？防火墙问题？这是所有文件。

IProductService1.cs

using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Web;
using System.Text;


namespace WCFRESTfulService
{
// NOTE: You can use the "Rename" command on the "Refactor" menu to change     the interface name "IService1" in both code and config file together.
[ServiceContract]
public interface IProductService1
{
    [OperationContract]
    [WebGet]
    List<product> GetAllProducts();

    [OperationContract]
    [WebGet]
    product GetProducts(string id);

}

}

ProductService1.svc.cs

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

namespace WCFRESTfulService
{
// NOTE: You can use the "Rename" command on the "Refactor" menu to change     the class name "Service1" in code, svc and config file together.
// NOTE: In order to launch WCF Test Client for testing this service, please   select Service1.svc or Service1.svc.cs at the Solution Explorer and start    debugging.
public class Service1 : IProductService1
{

    public List<product> GetAllProducts()
    {
        using(var db=new estocktakeEntities())
        {
            return db.products.ToList();
        }
    }


    public product GetProducts(string id)
    {
        Int32 _id = Convert.ToInt32(id);
        using(var db=new estocktakeEntities())
        {
            return db.products.SingleOrDefault(p => p.invtid == id);


        }


    }
}
}

当我使用 WCF 测试工具对其进行测试时，功能正常。

在网站上测试

将函数添加到url后

任何建议都会有很大帮助，很抱歉这篇长文。

-更新- 在 youtube 视频中可能时，仍然无法在浏览器中运行服务。使用 VS2013 网页版 SQL IIS Express

【问题讨论】：

数据库中有数据吗？
@Sajeetharan 是的，我的数据库有记录，它正在测试客户端中工作。
@Chris 看看你的浏览器控制台有什么？
@Mairaj 抱歉，您又指的是什么？我怎么给你看？
当您在浏览器中看到空白页面时，按 F12 并再次刷新页面，然后在控制台中看到错误。

【解决方案1】：

一般浏览器不显示xml结果，要从浏览器调用WCF方法，需要在WCF中创建Restful服务

以下链接应该会有所帮助，

Run WCF methods from a browser
