我需要 charset 为 utf-8,默认情况下似乎是这种情况。最近我为一些静态页面启用了页面缓存:
caches_page :about
缓存工作正常,我看到在我的 /public 文件夹中生成了相应的 about.html 和 contact.html 页面,除了页面呈现时,它不再是 utf-8。
在谷歌搜索了一下之后,我尝试在缓存之前和之后使用 wget 查看 http 标头:
第一次:
$wget --server-response http://localhost:3000/about
HTTP request sent, awaiting response...
1 HTTP/1.1 200 OK
2 X-Ua-Compatible: IE=Edge
3 Etag: "f7b0b4dea015140f3b5ad90c3a392bef"

结果页面以 ISO-8859-1 显示,我得到一堆乱码。有谁知道我可以如何防止这种不良结果?谢谢你。
