587d8248367417b2b2512c3b 使用 helment.ieNoOpen() 防止 IE 打开不受信任的 HTML 2 301584 prevent-ie-from-opening-untrusted-html-with-helmet-ienoopen

--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。

有些网站会下载不安全的 HTML 文件,某些版本的 IE 默认情况下还会在你网站的作用域下打开这些 HTML 文件。换句话说,这些不安全的 HTML 页面可以在你的网站做恶意行为。我们可以通过中间件来设置 header 中的 X-Download-Options 字段,让它的值为 noopen。这样就可以防止 IE 在不信任的网站下执行下载的文件。

--hints--

应正确加载 helmet.ieNoOpen() 中间件

(getUserInput) =>
  $.get(getUserInput('url') + '/_api/app-info').then(
    (data) => {
      assert.include(data.appStack, 'ienoopen');
      assert.equal(data.headers['x-download-options'], 'noopen');
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );
