如何修改.htaccess文件并获得SEO友好的URLS而不是查询字符串。我想实现这3个目标：
- localhost/example/products/而不是localhost/example/products-list.php
- localhost/example/products/38/而不是localhost/example/products.php？id=38
- localhost/example/products/38/red/而不是localhost/example/products.php？id＝38&color=红色
在另一个帖子上@anubhava帮了我很多，这就是我现在的第二点：
RewriteEngine on
RewriteBase /example
# external redirect from actual URL to pretty one
RewriteCond %{THE_REQUEST} /products(?:'.php)?'?id=([^'s&]+) [NC]
RewriteRule ^ products/%1? [R=302,L,NE]
# internal forward from pretty URL to actual one
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^products/([^/]+)/?$ products.php?id=$1 [L,QSA]
第二点很有效，但我想知道在之前或之后，我必须把其他规则放在哪里。我把这个放在另一个规则后面，但它不起作用，因为它重定向到以前的urllocalhost/example/products/38/:
# external redirect from actual URL to pretty one
RewriteCond %{THE_REQUEST} /products(?:'.php)?'?id=([^'s&]+)'?color=([^'s&]+) [NC]
RewriteRule ^ products/%1/%2? [R=302,L,NE]
# internal forward from pretty URL to actual one
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^products/([^/]+)/([^/]+)/?$ products.php?id=$1&color=$2 [L,QSA]
您需要两个参数的新规则集：
RewriteEngine on
RewriteBase /example/
# external redirect from actual URL to pretty one
RewriteCond %{THE_REQUEST} /products(?:'.php)?'?id=([^'s&]+)&color=([^'s&]+) [NC]
RewriteRule ^ products/%1/%2/? [R=302,L,NE]
RewriteCond %{THE_REQUEST} /products(?:'.php)?'?id=([^'s&]+)'s [NC]
RewriteRule ^ products/%1/? [R=302,L,NE]
RewriteCond %{REQUEST_FILENAME} -d [OR]
RewriteCond %{REQUEST_FILENAME} -f
RewriteRule ^ - [L]
# internal forward from pretty URL to actual one
RewriteRule ^products/([^/]+)/?$ products.php?id=$1 [NC,L,QSA]
RewriteRule ^products/([^/]+)/([^/]+)/?$ products.php?id=$1&color=$2 [NC,L,QSA]
RewriteRule ^products/?$ products-list.php [L,NC]
