服務器端得到cookie

1.
getname 獲取key getvalue 獲取值

Cookie[] cookie = request.getCookies();

response.getWriter().write("cookie獲取成功！");
for(Cookie cookie1:cookie)
{
response.getWriter().write(cookie1.getName()+cookie1.getValue()+cookie1.getPath());
}

當我們想要得到某個cookie的時候 可以將其封裝成一個工具類
Cookie IwantCookie=null;
if("key".equals(cookie1.getName())){
IwantCookie=cookie1;
response.getWriter().write(IwantCookie.getValue()+"</br>");
}
if(IwantCookie!=null)
System.out.println("找到了");
