微软MVC实现REST风格编程

1、总体来说很简单,首先新建一个MVC框架的项目,模板选择WebAPI,这样就搞定80%了。

2、WebApiConfig.cs

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

namespace UrlToPngWebAPI
{
    public static class WebApiConfig
    {
        public static void Register(HttpConfiguration config)
        {
            config.Routes.MapHttpRoute(
                name: "DefaultApi",
                routeTemplate: "api/{controller}/{id}",
                defaults: new { id = RouteParameter.Optional }
            );

            config.EnableSystemDiagnosticsTracing();
        }
    }
}

3、RouteConfig.cs

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

namespace UrlToPngWebAPI
{
    public class RouteConfig
    {
        public static void RegisterRoutes(RouteCollection routes)
        {
            routes.MapRoute(
                name: "Default",
                url: "{controller}/{action}/{id}",
                defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
            );
        }
    }
}

4、请求结构
Web2PNGRequest.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using Newtonsoft.Json;

namespace UrlToPngWebAPI.Models
{
    public class Web2PNGRequest
    {
        [JsonProperty]
        public String WebURL { get; set; }
        [JsonProperty]
        public String HeaderPath { get; set; }
        [JsonProperty]
        public String FooterPath { get; set; }
    }
}

5、返回结构
Web2PNGResponse.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using Newtonsoft.Json;

namespace UrlToPngWebAPI.Models
{
    public class Web2PNGResponse
    {
        [JsonProperty]
        public int ErrorCode { get; set; }
        [JsonProperty]
        public String ErrorInfo { get; set; }
        [JsonProperty]
        public String PNGPath { get; set; }
    }
}

6、Controller
Url2PNGController.cs

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Text;
using System.Web.Helpers;
using System.Web.Http;
using Newtonsoft.Json;
using UrlToPngCsTest;
using UrlToPngWebAPI.Models;
using UrlToPngWebAPI.Pulgins;

namespace UrlToPngWebAPI.Controllers
{
    public class Url2PNGController : ApiController
    {
        // 返回输入参数示例
        public HttpResponseMessage Get()
        {
            Web2PNGRequest req = new Web2PNGRequest();
            req.WebURL = "webURL";
            req.HeaderPath = "headerPath";
            req.FooterPath = "footerPath";

            String jsonString = JsonConvert.SerializeObject(req);
            HttpResponseMessage result = new HttpResponseMessage { Content = new StringContent(jsonString, Encoding.GetEncoding("UTF-8"), "application/json") };
            return result;
        }

        // GET
        public HttpResponseMessage Get(String WebURL, String HeaderPath, String FooterPath)
        {
            UrlToPng4Web.InitUrlTOPng4CS();

            Web2PNGRequest req = new Web2PNGRequest();
            req.WebURL = WebURL;
            req.HeaderPath = HeaderPath;
            req.FooterPath = FooterPath;
            Web2PNGResponse rsp = UrlToPng4Web.UrlToPNG(req);
            
            String jsonString = JsonConvert.SerializeObject(rsp);
            HttpResponseMessage result = new HttpResponseMessage { Content = new StringContent(jsonString, Encoding.GetEncoding("UTF-8"), "application/json") };
            return result;
        }

        // POST
        public HttpResponseMessage Post(Web2PNGRequest req)
        {
            UrlToPng4Web.InitUrlTOPng4CS();

            Web2PNGResponse rsp = UrlToPng4Web.UrlToPNG(req);

            String jsonString = JsonConvert.SerializeObject(rsp);
            HttpResponseMessage result = new HttpResponseMessage { Content = new StringContent(jsonString, Encoding.GetEncoding("UTF-8"), "application/json") };
            return result;
        }
    }
}
