在post的時(shí)候有時(shí)也用的到cookie洞渔，像登錄163發(fā)郵件時(shí)候就需要發(fā)送cookie堡妒，所以在外部一個(gè)cookie屬性隨時(shí)保存 CookieContainer cookie = new CookieContainer();
员凝！注意：有時(shí)候請(qǐng)求會(huì)重定向咆槽，但我們就需要從重定向url獲取東西，像QQ登錄成功后獲取sid瓣履，但上面的會(huì)自動(dòng)根據(jù)重定向地址跳轉(zhuǎn)船响。我們可以用:
request.AllowAutoRedirect = false;設(shè)置重定向禁用，你就可以從headers的Location屬性中獲取重定向地址
