为了让读者先对ASP.NET Web Api 有一个感性的认知,我们手动创建一个 Web API程序
创建一个空的项目,然后添加一下内容:
Common::空的类库项目。
Webapi:空的ASP.NET Web 应用,引用Common
WebHost:空的ASP.NET Web 应用,它实现了针对ASP.NET Web api的Web Host寄宿,引用webapi
SelHosst:空的控制台应用,它实现了针对ASP.NET Web api的Self Host寄宿,引用webapi
WebApp:空的ASP.NET Web 应用,重要用于ajax实现调用webapi
ConsoleApp:空的控制台应用,主要用于模拟客户端代理实现webapi远程调用
在Common创建Contact和Information
public class Contact { /// <summary> /// ID /// </summary> public string ID { get; set; } /// <summary> /// 姓名 /// </summary> public string Name { get; set; } /// <summary> /// 联系电话 /// </summary> public string PhoneNo { get; set; } /// <summary> /// 电子邮箱 /// </summary> public string EmailAddress { get; set; } /// <summary> /// 联系地址 /// </summary> public string Address { get; set; } /// <summary> /// 资料 /// </summary> public List<Information> lisInfo { get; set; } } public class Information { public string Education { get; set; } }
Webapi引入程序集System.Web.Http,并创建ContactsController
我们定义了Get,Post,Put,Delete这4个Action方法
public class ContactsController : ApiController { static List<Contact> contacts; static ContactsController() { contacts = new List<Contact>() { new Contact { ID = "001", Name = "张三", PhoneNo = "15811100056", EmailAddress = "zhangsanemail@163.com", Address = "北京市", lisInfo = new List<Information>() { new Information { Education = "小学" }, new Information { Education = "中学" } } }, new Contact { ID = "002", Name = "李四", PhoneNo = "0474-577466", EmailAddress = "lisiemail@163.com", Address = "内蒙古", lisInfo = new List<Information>() { new Information { Education = "高中" }, new Information { Education = "大学" } } } }; } public IEnumerable<Contact> Get(string id = null) { return from contact in contacts where contact.ID == id || string.IsNullOrEmpty(id) select contact; } public void Post(Contact contact) { contact.ID = "003"; contacts.Add(contact); } public void Put(Contact contact) { contacts.Remove(contacts.First(C => C.ID == contact.ID)); contacts.Add(contact); } public void Delete(string id) { contacts.Remove(contacts.First(C => C.ID == id)); } }
