WebApi个人理解概要

WebApi概要

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);
    }
}

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
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);

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();
    }
} 

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 }
