Java HttpServletResponse addCookie在chrome和ie上无用

标签: java cookies

我使用addCookie方法设置scdid,就像jsessionid一样。但遗憾的是,它在Chrome和IE浏览器上没用,这对Firefox来说还不错。

那么,有人能帮助我吗?

Cookie cookie = new Cookie("xx", "xxx");
cookie.setMaxAge(3600);
cookie.setDomain("xxxx"); 
cookie.setPath("/");
response.addCookie(cookie);

这是请求/响应正文:

2015-06-10编辑: 我通过以下方式解决了这个问题,但我仍然感到困惑。

Cookie cookie = new Cookie("examid", UUID.randomUUID().toString());
response.addCookie(cookie);

在此解决方案中,我没有设置过期,域名和路径,从Chrome中的jsessionid获取灵感。

2015-06-12编辑: 我逐个设置MaxAge,路径,域。我发现设置域(来自请求参数)时它会出错。我的代码是如何获取域名的:

private static final String getDomainName(HttpServletRequest request) {
    String domainName = null;

    String serverName = request.getRequestURL().toString();
    if (serverName == null || serverName.equals("")) {
        domainName = "";
    } else {
        serverName = serverName.toLowerCase();
        serverName = serverName.substring(7);
        final int end = serverName.indexOf("/");
        serverName = serverName.substring(0, end);
        final String[] domains = serverName.split("\\.");
        int len = domains.length;
        if (len > 3) {
            // www.xxx.com.cn
            domainName = "." + domains[len - 3] + "." + domains[len - 2] + "." + domains[len - 1];
        } else if (len <= 3 && len > 1) {
            // xxx.com or xxx.cn
            domainName = "." + domains[len - 2] + "." + domains[len - 1];
        } else {
            domainName = serverName;
        }
    }

    if (domainName != null && domainName.indexOf(":") > 0) {
        String[] ary = domainName.split("\\:");
        domainName = ary[0];
    }
    return domainName;
}

回答更新后的问题:

  

实际上,我得到了域名&#34; localhost&#34;按我的代码

所以这就是问题所在:如果您的域名= localhost,则不会设置cookie。通过spec,cookie域名必须至少有2或3个点(。)。 Localhost是顶级域名,因此无法使用。不遵守此规则可能会导致某些浏览器出现问题:

  

只有指定域中的主机才能为域设置cookie   和域必须至少有两(2)或三(3)个句点   防止表格的域名:&#34; .com&#34;,&#34; .edu&#34;,&#34; va.us&#34;。

作为解决方案,在使用localhost时,我建议您不要设置域名,或者只使用127.0.0.1

您的Chrome和IE浏览器中是否禁用了Cookie?

答案 2 :(得分:0)

HttpServletResponse-> flushBuffer()对我来说绝对好用。

response.flushBuffer();
