console.log("headers: ", resHttps.headers);

得到的结果如下： headers: { server: 'nginx/0.7.64’, date: 'Tue, 17 Jul 2012 06:30:58 GMT’, 'content-type’: 'images/jpg; charset=utf-8’, connection: 'keep-alive’, 'content-length’: '41013’, 'content-disposition’: ‘attachment; filename="23970002402972637061382188.jpg"’ }

怎么写js获取到filename，高手帮忙解答下啊，hoho。
