WebApi概要
  1. Global文件的作用:

    public class MvcApplication : System.Web.HttpApplication
    {
        protected void Application_Start()
        {
            //1.注册区域路由
            AreaRegistration.RegisterAllAreas();
            //2.注册webApi的路由
            WebApiConfig.Register(GlobalConfiguration.Configuration);
            //3.注册全局过滤器
            FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
            //4.注册网站路由
            RouteConfig.RegisterRoutes(RouteTable.Routes);
            //5.优化js、cs
            BundleConfig.RegisterBundles(BundleTable.Bundles);
        }
    }
  2. WebApi特点

    1. 类必须继承ApiController            

    2. 返回类型不再是ActionResult

    3. 默认是请求WebApi控制器中的和HttpMethod同名的方法

  3. 设置当前WebApi的默认返回格式为json--移除xml格式

    1. config.Formatters.Remove(config.Formatters.XmlFormatter);

  4. 网站访问WebApi,要提供相应的url接口

    //http://localhost:4221/api/values/getpiglist
    protected void Page_Load(object sender, EventArgs e)
    {
        //1.拼装要请求数据的url
        string url = "http://localhost:4221/api/values/getpiglist";
        //2.利用C#模拟浏览器发出请求
        WebRequest request = WebRequest.Create(url);
        //2.1设置请求方式,如果不设置则默认为get
        request.Method = "get";
        //3.获取响应报文
        WebResponse response = request.GetResponse();
        //4.获取相应报文体的字节数据byte[]
        System.IO.Stream responseBody = response.GetResponseStream();
        //5.将字节数据转换为字符串
        using(StreamReader sr=new StreamReader(responseBody))
        {
            //5.1将相应报文体转换为json字符串
            string responseBodyText = sr.ReadToEnd();
            //5.2利用json序列化器将json字符串反序列化为list集合
            System.Web.Script.Serialization.JavaScriptSerializer jss = new System.Web.Script.Serialization.JavaScriptSerializer();
            List<Entity> list = jss.Deserialize(responseBodyText, typeof(List<Entity>)) as List<Entity>;
            GridView1.DataSource = list;
            GridView1.DataBind();
        }
  5. 动态页面转静态

     1 private void MakeStaticPage(string url) 2 { 3 string txtHtml = ""; 4 string fileName = Guid.NewGuid().ToString() + ".html"; 5 //1.C#模拟浏览器发出请求 6 WebRequest Request = WebRequest.Create(url); 7 //2.获取Response对象 8 WebResponse response = Request.GetResponse(); 9 //3.根据响应报文获取字节流10 Stream stream = response.GetResponseStream();11 //4.字节流转换为html文本,并存储到相应文本中12 using (StreamReader sr = new StreamReader(stream))13 {14 txtHtml = sr.ReadToEnd();15 File.WriteAllText(Server.MapPath("/staticPage/" + fileName), txtHtml);16 }17 Response.Write("<script>alert(‘静态化成功 !‘);</script>");18 }

     

三、MVC插件系统
