node.js - Express 在浏览器中返回 200，但使用 curl -I 返回 404

Question

我有一个快速服务器，它提供一些静态文件。

当我从浏览器发出请求时，一切都很好。但是当我使用 cURL 时，它变得有点奇怪:

• curl https://www.goukitok.com :带有页面内容的 HTTP 200
• curl -I https://www.goukitok.com:HTTP 404(请参阅下面的详细日志)。

我需要 curl -I 才能工作，因为我的客户需要通过 Google AdWords 宣传此页面，而 Google 在允许他创建广告之前会执行检查。

我的服务器托管在 Heroku 上。

我不明白是什么造成的？你有什么想法吗？

提前致谢!

Answer 1

我通过在路由文件的开头强制使用静态路径来解决这个问题。这是中间件顺序的问题

正如@PeterVC指出的here我的服务器未处理 HEAD 请求(使用 I 标志时由 cURL 发送)。

我刚刚将 app.use('/',express.static(path.join(__dirname, '../../dist'))) 移动到我的 Express 路由器的顶部文件。
