.net - REST 服务未在浏览器中显示结果

Question

我正在尝试使用 Rest 为大学项目创建自己的 Web 服务。在完成一些教程后，我已经能够创建自己的服务，并且该服务正在使用 wcf 测试客户端在 Visual Studio 中运行并返回结果。

但是，当我浏览到服务(http://localhost:53215/UserService1.svc)时，我可以看到服务页面，但是http://localhost:53215/UserService1。 svc/GetUsersNames 发送给我 404，页面未找到错误!

有人能看出我做错了什么吗？

这是我的代码。

Web.config

    <compilation debug="true" targetFramework="4.0">

      </service>

</configuration>

IUserService.cs

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

namespace WcfRestSample
{
    // NOTE: You can use the "Rename" command on the "Refactor" menu to change the interface name "IUserService1" in both code and config file together.
    [ServiceContract]
    public interface IUserService1
    {
        [OperationContract]
        [WebGet(ResponseFormat = WebMessageFormat.Xml)]
        List<string> GetUsersNames();
    }
}

UserService1.svc

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

namespace WcfRestSample
{
    // NOTE: You can use the "Rename" command on the "Refactor" menu to change the class name "UserService1" in code, svc and config file together.
    // NOTE: In order to launch WCF Test Client for testing this service, please select UserService1.svc or UserService1.svc.cs at the Solution Explorer and start debugging.
    public class UserService1 : IUserService1
    {
        public List<string> GetUsersNames()
        {
            using (cs4_databaseEntities entities = new cs4_databaseEntities())
            {
                return entities.Users.Select(user => user.Name).ToList();
            }
        }
    }
}

我使用的教程在浏览器上运行良好!

Answer 1

您的端点是http://localhost:53215/UserService1.svc/rest/GetUsersNames。 “rest”部分来自您的配置“address=”rest””

编辑:

服务名称设置为接口(interface)而不是实现类，更改:

<service name="WcfRestSample.IUserService1">

到

<service name="WcfRestSample.UserService1">

这样做的一个后果是该服务不再在 wcf 测试客户端中加载，也许这就是为什么它会造成困惑 - 有些人记录了使用 wcf 测试客户端的步骤，而其他人则记录了使用 Web 浏览器的步骤 但它是一个简单的修复方法，可以将其改回使用界面!
