CookieManager 提供 CookieHandler 的具体实现，它将 cookie 的存储区与围绕接受和拒绝 cookie 的策略分离开来。使用管理存储的 CookieStore 以及做出 cookie 接受/拒绝决策的 CookiePolicy 对象来初始化 CookieManager。 -/********************************************************************************//**

A typical usage of this class would look something like this:



CookieManager cookieManager = new CookieManager()

// Set a cookie value

cookieManager.CookieValues["FavoriteCookie"] = "Chocolate Chip"



HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(url)

// Publish the cookies to the request before asking for the response

cookieManager.PublishCookies(webRequest)



HttpWebResponse webResponse = (HttpWebResponse)webRequest.GetResponse()

// Store any cookies returned from the response

cookieManager.StoreCookies(webResponse)



// Get the value of a cookie

string session = cookieManager.CookieValues["SESSIONID"]



webRequest = (HttpWebRequest)WebRequest.Create(url2)

cookieManager.PublishCookies(webRequest)



webResponse = (HttpWebResponse)webRequest.GetResponse()
