会话技术_Cookie_细节1_发送多个Cookie

      1.cookie的细节

         1.一次可不可以发送多个cookie?

              是可以的

              可以创建多个Cookie对象,使用response调用多次addCookie方法发送cookie即可

          

 

package bd.xueqiang.Cookie;

import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.Cookie;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

@WebServlet("/cookieDemo03")
public class CookieDemo03 extends HttpServlet {
    /**
     * Cookis快速入门
     * @param request
     * @param response
     * @throws ServletException
     * @throws IOException
     */

    @Override
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        //1.创建Cookie对象
        Cookie msg1 = new Cookie("msg", "hello");
        Cookie msg2= new Cookie("fly", "yinuo");
        //2.发送Cookis
        response.addCookie(msg1);
        response.addCookie(msg2);


    }

    @Override
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        this.doPost(request, response);
    }
}

 

 

         2.cookie在浏览器中保存多次时间?

         3.cookie能不能中文?

         4.cookie获取范围多大?
