--description--
请注意,本项目在 这个 Repl.it 项目 的基础上进行开发。你也可以从 GitHub 上克隆。
如果黑客发现你的网站是用 Express 搭建的,那么他们就可以利用 Express 或 Node 现存的漏洞来攻击你的网站。X-Powered-By: Express
默认情况下会添加到所有响应的 header。不过 helmet.hidePoweredBy()
中间件可以帮你把 header 中的 X-Powered-By 字段移除。你甚至可以把它设置成其它的值来骗过黑客,比如 app.use(helmet.hidePoweredBy({ setTo: 'PHP 4.2.0' }))
--hints--
应正确地加载 helmet.hidePoweredBy() 中间件
(getUserInput) =>
$.get(getUserInput('url') + '/_api/app-info').then(
(data) => {
assert.include(data.appStack, 'hidePoweredBy');
assert.notEqual(data.headers['x-powered-by'], 'Express');
},
(xhr) => {
throw new Error(xhr.responseText);
}
);
