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' }))

Instructions

Tests

tests:
  - text: 应正确地加载 helmet.hidePoweredBy() 中间件
    testString: 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); })
