我正在尝试设置Cookie的域名。但它不起作用,我的cookie不会在此之后创建:
javax.servlet.http.Cookie responseCookie =
new Cookie(startpackCookie.getName(),
startpackCookie.getValue());
responseCookie.setMaxAge(startpackCookie.getMaxAge());
responseCookie.setPath(startpackCookie.getPath());
responseCookie.setDomain(startpackCookie.getDomain());
System.out.println("Cookie max age: " +
responseCookie.getMaxAge());
System.out.println("Cookie path: " + responseCookie.getPath());
System.out.println("Cookie domain: " + responseCookie.getDomain());
response.addCookie(responseCookie);
输出:
10:28:34,899 INFO [stdout] (http-/127.0.0.1:8080-5) Cookie max age: -1
10:28:34,900 INFO [stdout] (http-/127.0.0.1:8080-5) Cookie path: /
10:28:34,900 INFO [stdout] (http-/127.0.0.1:8080-5) Cookie domain: playground.startpack.ru
10:28:34,901 INFO [stdout] (http-/127.0.0.1:8080-5) Cookie was sended
如果我要删除域名设置,则可以使用localhost
域名。怎么了?
答案 0 :(得分:1)
来自Sun的网站, “默认情况下,cookie只会返回给保存它们的主机。”
域名也以点(“.foo.com”)开头,对指定域名系统(DNS)区域中的服务器可见(例如,www.foo.com,但不是abfoo.com)
