Web API 设置Cookie 以及 Session 问题

 

1： 设置Cookin 方法一

　　　请参考我的另一篇: Connkin 方法一

2： 设置Cookin 方法二

　　　　

            //Cookie 的设置读取
            HttpCookie coo = HttpContext.Current.Request.Cookies["BF"];
            if (coo == null)
            {
                coo = new HttpCookie("BF");
                coo["User.ITCode"] = "张三";
                coo["CurrentLanguage"] = "Chinese";
                coo.Expires = DateTime.Now.AddDays(7.0);

                HttpContext.Current.Request.Cookies.Remove("BF");
                HttpContext.Current.Response.Cookies.Remove("BF");
                HttpContext.Current.Request.Cookies.Add(coo);
                HttpContext.Current.Response.Cookies.Add(coo);
            }

　　

3： API 设置Session 问题，

　　 API 在默认的情况下是不开启Session的，所以我们需要重写配置，否则我们在HttpContext.Current.Session  使用的时候，返回的都是NULL。

第一步： 从写 SessionRouteHandler

　　　　

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

namespace BF.API
{
    public class SessionRouteHandler : HttpControllerHandler, IRequiresSessionState
    {
        public SessionRouteHandler(RouteData routeData) : base(routeData) { }
    }
}

　　

第二步： 从写 SessionControllerRouteHandler

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

namespace BF.API
{
    public class SessionControllerRouteHandler : IRouteHandler
    {
        public IHttpHandler GetHttpHandler(RequestContext requestContext)
        {
            return new SessionRouteHandler(requestContext.RouteData);
        }
    }
}

　　

第三步：配置路由WebApiConfig

using BFKR.API.Cookie;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Http;
using System.Web.Http.Cors;
using System.Web.Routing;

namespace BFKR.API
{
    public static class WebApiConfig
    {
        public static void Register(HttpConfiguration config)
        {
            //跨域配置
            config.EnableCors(new EnableCorsAttribute("*", "*", "*"));

            //webApi路由
            config.MapHttpAttributeRoutes();

            RouteTable.Routes.MapHttpRoute(
               name: "DefaultApi",
               routeTemplate: "api/{controller}/{action}/{id}",
               defaults: new { id = RouteParameter.Optional }
             ).RouteHandler = new SessionControllerRouteHandler();

            //移除xml返回格式数据
            GlobalConfiguration.Configuration.Formatters.XmlFormatter.SupportedMediaTypes.Clear();

            //配置返回的时间类型数据格式  
            GlobalConfiguration.Configuration.Formatters.JsonFormatter.SerializerSettings.Converters.Add(
                new Newtonsoft.Json.Converters.IsoDateTimeConverter()
                {
                    DateTimeFormat = "yyyy-MM-dd HH:mm:ss"
                }
            );
        }
    }
}

　　

第四步：配置Global

　　

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Http;
using System.Web.Mvc;
using System.Web.Routing;
using System.Web.Security;
using System.Web.SessionState;

namespace BFKR.API
{
    public class Global : System.Web.HttpApplication
    {

        protected void Application_Start(object sender, EventArgs e)
        {
            AreaRegistration.RegisterAllAreas();
            GlobalConfiguration.Configure(WebApiConfig.Register);
        }

        public override void Init()
        {
            this.PostAuthenticateRequest += (y, z) => HttpContext.Current.SetSessionStateBehavior(System.Web.SessionState.SessionStateBehavior.Required);

            base.Init();
        }

        protected void Session_Start(object sender, EventArgs e)
        {

        }

        protected void Session_End(object sender, EventArgs e)
        {

        }

        protected void Application_BeginRequest(object sender, EventArgs e)
        {

        }

        protected void Application_AuthenticateRequest(object sender, EventArgs e)
        {

        }

        protected void Application_Error(object sender, EventArgs e)
        {

        }

        protected void Application_End(object sender, EventArgs e)
        {

        }
    }
}

　　

第五步： 这个时候就可以设置Session了

            //Session 的读取
            string SESSION_KEY = "BF_Session";
            string name = "李四";
            //赋值
            HttpContext.Current.Session[SESSION_KEY] = name;
            //设置过期时间
            HttpContext.Current.Session.Timeout = 30;
            //读取
            string namestr = HttpContext.Current.Session[SESSION_KEY] as string;

            //都是删除
            HttpContext.Current.Session.Remove(SESSION_KEY);
            HttpContext.Current.Session[SESSION_KEY] = null;
