我负责 www.lesscss.org。来源在这里https://github.com/cloudhead/lesscss.org。

这是一个瘦 Web 应用程序，在 heroku 上运行。在浏览器中访问该网站很好。

我们有一个错误， curl -I lesscss.org 给出了 400 请求 - https://github.com/cloudhead/less.js/issues/1232

它确实

$ curl -I lesscss.org
HTTP/1.1 400 Bad Request
Server: nginx
Date: Tue, 19 Mar 2013 01:15:50 GMT
Connection: close

我做了很多搜索，但没有找到原因或如何纠正上述问题.. 不应该是 302 重定向还是 200 ok？

带有详细选项

您正在使用的 toto 引擎中有这一行：

return [400, {}, []] unless @request.get?

所以任何不是 get 的东西都会导致 400。Toto 可能会允许 head 请求通过（如果需要，可以结合 Rack::Head 将请求主体放在地板上）

与-I您提出HEAD请求而不是GET. 删除-I标志，它将起作用。您可以看到它如何与-v标志一起使用：

curl -Iv lesscss.org
