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

但是，当我浏览到服务时（http://localhost:53215/UserService1.svc），我可以看到服务页面，但http://localhost:53215/UserService1.svc/GetUsersNames发送给我 404，找不到页面错误！

谁能看到我做错了什么？

这是我的代码。

namespace WcfRestSample

    [ServiceContract]
    public interface IUserService1

        [OperationContract]
        [WebGet(ResponseFormat = WebMessageFormat.Xml)]
        List<string> GetUsersNames();
    }
}

用户服务1.svc

using System;

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！

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服务不再加载到 wcf 测试客户端中，也许这就是它造成混淆的原因 - 有些人记录了他们使用 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，但它很容易解决改回使用界面！

更改<service name="WcfRestSample.IUserService1">为<service name="WcfRestSample.UserService1">. 感谢评论中的用户-Marvin Smitt
