  • Asp.net Mvc Web Api 学习(一)

    看了很久终于有点眉目了。

    首先建一个项目Asp.net MVC4 Web Application下的Web Api项目;

    在Controllers文件夹下新建一个类(继承 ApiController)

     public class UserController : ApiController
        {
            public IQueryable<User> Get()
            {
                return List.AsQueryable();
            }

            public User Get(string id)
            {
                User user = List.Single<User>(u => u.userNo == id);
                if (user != null)
                {
                    return user;
                }
                return user;
            }

            public bool Post(User user)
            {
                if (user != null)
                {
                    List.Add(user);
                    return true;
                }
                return false;
            }

            public bool Put(User user)
            {
                if (user != null)
                {
                    User u = List.Single<User>(mu => mu.userNo == user.userNo);
                    List.Remove(u);
                    List.Add(user);
                    return true;
                }
                return false;
            }

            public bool Delete(string id)
            {
                if (id != null)
                {
                    User u = List.Single<User>(mu => mu.userNo == id);
                    List.Remove(u);
                    return true;
                }
                return false;
            }

            /// <summary>
            /// 测试数据
            /// </summary>
            private static List<User> List = new List<User>();
           
            public class User
            {
                public string userNo { get; set; }
                public string Name { get; set; }
                public string Pwd { get; set; }
            }
        }

    需要注意一下方法名(get ,post,put,delete)和参数名(string id)和Global.asax对应。

    客户端代码:

    好像其他没啥要改的,初步就这样吧。
