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);
}
}
});
