--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。

如果你为你的网站发布了一个更新,此时你一定想要用户看到最新的版本。为此,你可以通过禁用浏览器缓存来实现。而且,这个功能在开发环境中也非常有用。但另一方面,缓存可以为你的网站带来性能方面的提升,因此你应该只在必要的时候禁用缓存。

--hints--

应正确加载 helmet.noCache() 中间件

(getUserInput) =>
  $.get(getUserInput('url') + '/_api/app-info').then(
    (data) => {
      assert.include(data.appStack, 'nocache');
      assert.equal(
        data.headers['cache-control'],
        'no-store, no-cache, must-revalidate, proxy-revalidate'
      );
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );
