cookie_0">一次可不可以发送多个cookie?

创建一个cookieDemo3传两个Servlet

java">@WebServlet("/cookieDemo3")
public class CookieDemo3 extends HttpServlet {
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

        //创建cookie对象
        Cookie c1 = new Cookie("msg","hello");
        //发送cookie
        response.addCookie(c1);

        //创建cookie对象
        Cookie c2 = new Cookie("name","zhangsan");
        //发送cookie
        response.addCookie(c2);
    }

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

在火狐浏览器中的展示如下:两个cookie都发过去了

在CookieDemo2中接收数据

java">@WebServlet("/cookieDemo2")
public class CookieDemo2 extends HttpServlet {
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

        //获取cookie
        Cookie[] cs = request.getCookies();
        //获取数据, 遍历Cookies
        if (cs != null) {
            for (Cookie c : cs) {
                String name = c.getName();//对应名称
                String value = c.getValue();//对应值
                System.out.println(name+":"+value);
            }
        }

    }

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

在火狐浏览器中访问cookieDemo2, 打开开发者模式, 如下:

在控制台中打印如下

所以, 一次可不可以发送多个cookie
