WEBAPI Overview of Personal understanding

Webapi Overview

1. The role of the global file:

   12345678910111213141516

   publicclassMvcApplication : System.Web.HttpApplication{    protectedvoidApplication_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);    }}

3. WEBAPI Features

1. Class must inherit Apicontroller

2. The return type is no longer actionresult

3. The default is to request a method with the same name as HttpMethod in the WEBAPI controller

5. Sets the default return format for the current WEBAPI to json--remove XML format

1. Config. Formatters.remove (config. Formatters.xmlformatter);

6. Web site access Webapi, to provide the appropriate URL interface

   //http://localhost:4221/api/values/getpiglistprotectedvoidPage_Load(objectsender, EventArgs e){    //1.拼装要请求数据的url    stringurl = "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=newStreamReader(responseBody))    {        //5.1将相应报文体转换为json字符串        stringresponseBodyText = 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 = newSystem.Web.Script.Serialization.JavaScriptSerializer();        List<Entity> list = jss.Deserialize(responseBodyText, typeof(List<Entity>)) asList<Entity>;        GridView1.DataSource = list;        GridView1.DataBind();    }}

7. Dynamic page Turn static

   1 Private voidMakestaticpage (stringURL)2 {3 stringtxthtml ="";4 stringFileName = Guid.NewGuid (). ToString () +". html";5 //1.c# Impersonation browser making a request6WebRequest Request =webrequest.create (URL);7 //2. Get the Response object8WebResponse response =request.getresponse ();9 //3. Get the byte stream based on the response messageTenStream stream =Response. GetResponseStream (); One //4. Byte stream is converted to HTML text and stored in the corresponding text A using(StreamReader sr =NewStreamReader (stream)) - { -txthtml =Sr. ReadToEnd (); theFile.writealltext (Server.MapPath ("/staticpage/"+fileName), txthtml); - } -Response.Write ("<script>alert (' static success! '); </script>"); -}

Third, the MVC plug-in system
