并且我们知道了Post,Put方法只能有一个FromBody参数,再有多个参数时,上讲提到,需要将它封装成一个对象进行传递,而这讲主要围绕这个话题来说,接口层添加一个新类User_Info,用来进行数据传递,而客户端使用网页ajax和控制台HttpClient的方式分别进行实现,Follow me!
下面定义一个复杂类型对象
public class User_Info { public int Id { get; set; } public string Name { get; set; } public string Info { get; set; } }
下面修改上次的api部分,让它对这个对象进行操作
[CorsAttribute("http://localhost:3321")] public class RegisterController : ApiController { public static List<User_Info> Model = new List<User_Info>() { new User_Info{Id=1,Name="zzl",Info="zzl是楼主"}, new User_Info{Id=2,Name="zhz",Info="zhz是zzl的儿子"}, new User_Info{Id=3,Name="zql",Info="zql是zzl的妻子"}, new User_Info{Id=4,Name="bobo",Info="bobo是zzl的朋友"} }; // GET api/values public IEnumerable<User_Info> Get() { return Model; } // GET api/values/5 public User_Info Get(int id) { var entity = Model.FirstOrDefault(i => i.Id == id); return entity; } // GET api/values/5?leval=1 public HttpResponseMessage Get(int id, int leval) { return new HttpResponseMessage(HttpStatusCode.OK) { Content = new StringContent("<em style=‘color:red‘>成功响应(id,level)</em>", System.Text.Encoding.UTF8, "text/html") }; } // POST api/values public HttpResponseMessage Post([FromBody]User_Info value) { Model.Add(new User_Info { Id = value.Id, Info = value.Info, Name = value.Name, }); //用户登陆相关 return new HttpResponseMessage(HttpStatusCode.OK) { Content = new StringContent("添加数据成功,用户ID:" + value.Id, System.Text.Encoding.UTF8, "text/plain") }; } // PUT api/values?userid=5 public HttpResponseMessage Put(int userid, [FromBody]User_Info value) { var entity = Model.FirstOrDefault(i => i.Id == userid); entity.Info = value.Info; entity.Name = value.Name; return new HttpResponseMessage(HttpStatusCode.OK) { Content = new StringContent("修改数据成功,主键:" + userid + ",对象:" + value.Name) }; } // DELETE api/values/5 public HttpResponseMessage Delete(int id) { Model.Remove(Model.FirstOrDefault(i => i.Id == id)); return new HttpResponseMessage(HttpStatusCode.OK) { Content = new StringContent("删除数据成功") }; }
而最关键的地方还是在各个客户端调用的时候,首先,你不能指望客户端去引用你的程序集,因为,不能平台无法实现这种引用(java & c#,js & C#,php & c#),所以,在调用时需要有它们各自的方法,而JS的ajax调用时,直接使用json对象即可,键名对象
实体的属性,在使用HttpClient时,直接为FormUrlEncodedContent对象赋一个键值对的集合即可,下面分别介绍一下
HTML的JS实现
$.ajax({ url: "http://localhost:52824/api/register", type: "POST", data: { Id: 5, Name: ‘新来的‘, Info: ‘大家好‘ },//这里键名称必须为空,多个参数请传对象,api端参数名必须为value success: function (data) { console.log("post:" + data); } }); $.ajax({ url: "http://localhost:52824/api/register", type: "GET", success: function (data) { for (var i in data) { console.log(data[i].Id + " " + data[i].Name); } } });
结果截图
Console程序中使用HttpClient对象进行实现
/// <summary> /// HttpClient实现Post请求 /// </summary> static async void dooPost() { string url = "http://localhost:52824/api/register"; //设置HttpClientHandler的AutomaticDecompression var handler = new HttpClientHandler() { AutomaticDecompression = DecompressionMethods.GZip }; //创建HttpClient(注意传入HttpClientHandler) using (var http = new HttpClient(handler)) { //使用FormUrlEncodedContent做HttpContent var content = new FormUrlEncodedContent(new Dictionary<string, string>() { {"Id","6"}, {"Name","添加zzl"}, {"Info", "添加动作"}//键名必须为空 }); //await异步等待回应 var response = await http.PostAsync(url, content); //确保HTTP成功状态值 response.EnsureSuccessStatusCode(); //await异步读取最后的JSON(注意此时gzip已经被自动解压缩了,因为上面的AutomaticDecompression = DecompressionMethods.GZip) Console.WriteLine(await response.Content.ReadAsStringAsync()); } } /// <summary> /// HttpClient实现Get请求 /// </summary> static async void dooGet() { string url = "http://localhost:52824/api/register?id=1"; //创建HttpClient(注意传入HttpClientHandler) var handler = new HttpClientHandler() { AutomaticDecompression = DecompressionMethods.GZip }; using (var http = new HttpClient(handler)) { //await异步等待回应 var response = await http.GetAsync(url); //确保HTTP成功状态值 response.EnsureSuccessStatusCode(); //await异步读取最后的JSON(注意此时gzip已经被自动解压缩了,因为上面的AutomaticDecompression = DecompressionMethods.GZip) Console.WriteLine(await response.Content.ReadAsStringAsync()); } } /// <summary> /// HttpClient实现Put请求 /// </summary> static async void dooPut() { var userId = 1; string url = "http://localhost:52824/api/register?userid=" + userId; //设置HttpClientHandler的AutomaticDecompression var handler = new HttpClientHandler() { AutomaticDecompression = DecompressionMethods.GZip }; //创建HttpClient(注意传入HttpClientHandler) using (var http = new HttpClient(handler)) { //使用FormUrlEncodedContent做HttpContent var content = new FormUrlEncodedContent(new Dictionary<string, string>() { {"Name","修改zzl"}, {"Info", "Put修改动作"}//键名必须为空 }); //await异步等待回应 var response = await http.PutAsync(url, content); //确保HTTP成功状态值 response.EnsureSuccessStatusCode(); //await异步读取最后的JSON(注意此时gzip已经被自动解压缩了,因为上面的AutomaticDecompression = DecompressionMethods.GZip) Console.WriteLine(await response.Content.ReadAsStringAsync()); } }
