WebAPI例子

1.WebApiConfig配置API路由

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web.Http;

namespace WebAPIDemo1
{
    public static class WebApiConfig
    {
        public static void Register(HttpConfiguration config)
        {
            // Web API 配置和服务

            // Web API 路由
            config.MapHttpAttributeRoutes();

            config.Routes.MapHttpRoute(
                name: "DefaultApi",
                 //api/controller控制器名/action方法名/id参数名
                 routeTemplate: "api/{controller}/{action}/{id}",

                // routeTemplate: "api/{controller}",
                defaults: new { id = RouteParameter.Optional }
            );
        }
    }
}

2.配置Global.asax文件中Application_Start

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Http;
using System.Web.Routing;

namespace WebAPIDemo1
{
    public class WebApiApplication : System.Web.HttpApplication
    {
        protected void Application_Start()
        {
            GlobalConfiguration.Configure(WebApiConfig.Register);
        }
    }
}

3.创建PersonController控制器

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Web.Http;
using WebAPIDemo1.Models;

namespace WebAPIDemo1.Controllers
{
    public class PersonController : ApiController
    {
        #region GET
        // /api/person/Get
        public string[] Get()
        {
            return new string[] { "ru", "qq", "wx" };
        }
        // /api/person/Get?id=
        public string Get(int id)
        {
            return "这是：" + id;
        }
        // /api/person/Get?name=
        public string Get(string name)
        {
            return "姓名：" + name;
        }
        #endregion
        #region Post
        /// <summary>
        /// 参数在地址栏上
        /// </summary>
        /// <param name="value"></param>
        /// <returns></returns>
        // /api/person/Post?value=123
        public string Post(string value)
        {
            return "Post请求值" + value;
        }
        /// <summary>
        /// 参数不在地址栏上
        /// </summary>
        /// <param name="value"></param>
        /// <returns>/api/person/Post </returns>
        public string Post([FromBody]BodyValue value)
        {
            return "Post请求值" + value.value;
        } 
        #endregion

        public string Put(int id, [FromBody] string value)
        {
            return "Put请求值：" + value + ",id:" + id;
        }

        public string Delete(int id)
        {

            return "数据id为" + id + "删除成功";
        }
        //[HttpGet]
        [HttpPost]
        // /api/person/Login?Uid=admin&Pwd=123
        public bool Login(string Uid, string Pwd)
        {
            if (Uid == "admin" && Pwd == "123")
                return true;
            else
                return false;
        }

        [HttpGet]
        //入参实体参数FromUri
        //api/person/Login2?Uid=admin&Pwd=456
        public bool Login2([FromUri] UseInfo Model)
        {
            if (Model.Uid == "admin" && Model.Pwd == "123")
                return true;
            else
                return false;
        }
        //Post  表单提交类型application/x-www-form-urlencoded
        //body==>raw==>json==>{"Uid":"admin","Pwd":"123"}
        //api/person/Login3
        [HttpPost]
        public bool Login3([FromBody] UseInfo Model)
        {
            if (Model.Uid == "admin" && Model.Pwd == "123")
                return true;
            else
                return false;
        }

    }
}

4.创建DogController

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Web.Http;

namespace WebAPIDemo1.Controllers
{
    [RoutePrefix("api/Test")]
    //第三种/api/Dog/Get
    public class DogController : ApiController
    {
        [HttpGet]
        //[Route("api/Dog/Get888")]第二种/api/Dog/Get888
        //[Route("Get888")] //第一种/api/Test/Get888
        //不加route  /api/Dog/Get888
        public string Get()
        {
            return "Get666";
        }

        [HttpGet]
        [Route("Login/{Uid}/{Pwd}")]
        //加route /api/Test/Login/123/456
        //参数地址化
        public bool Login(string Uid,string Pwd)
        {
            if (Uid == "admin" && Pwd == "123")
                return true;
            else
                return false;
        }
    }
}
