java处理cookie中带特殊符号的方法

String cookieValue = '';
String cookieStr = request.getHeader('cookie');
String[] cookies = cookieStr.split(';');
for(int i=0;i<cookies.length;i++){
   String cookie = cookies[i].trim();
   if(cookie.startsWith('LtpaToken=')){//判断的是cookie的名称
      cookieValue = cookie;
      break;
   }
}
