在浏览器中快速返回 200，但使用 curl -I 返回 404答案

【问题标题】：Express return 200 in browser but 404 with curl -I在浏览器中快速返回 200，但使用 curl -I 返回 404
【发布时间】：2023-03-21 02:20:02
【问题描述】：

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 推广此页面，并且 Google 会在允许他制作广告之前进行检查。

我的服务器托管在 Heroku 上。

我不知道是什么造成的？你有什么想法吗？

提前致谢！

【问题讨论】：

你的节点代码是否响应 HEAD 请求？
@PeterVC 根据 Express doc“如果 app.head() 之前的路径没有调用 app.head() 。得到（）。”所以我会说是的
查看两个日志，我看到的唯一区别是 HEAD 请求。如果没有看到您的代码，我们无法判断您是否覆盖了默认行为。
@PeterVC 我正在以这种方式进行调查。谢谢

标签： node.js http express curl heroku

【解决方案1】：

我通过在路由文件的最开头强制执行静态路径来解决这个问题。是中间件顺序的问题

正如@PeterVC 指出的here 我的服务器没有处理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'))) 移动到我的快速路由器文件的顶部。
