这些被称为 RewriteRule s，它们非常简单:

These are known as RewriteRules, and they are fairly straightforward:

RewriteEngine on
RewriteRule ^about$ /index.php?app=about

此处是文档

就使其更通用而言，如何处理:

As far as making it more generic, how about this:

RewriteEngine on
RewriteRule ^([A-Za-z]+)$ /index.php?app=$1

这会将对/staff或/contact之类的任何请求重定向到index.php?app = [staff | contact]

This will make any request to something like /staff or /contact redirect to index.php?app=[staff|contact]
