Question

我的RewriteRule中有一个正则表达式，目前工作正常。其次，我想测试文件（请求被重写的位置）存在。因此，我在我的规则之前放置了一个RewriteCond，但不幸的是，它总是被证实为假。

这是我的正则表达式：

assets/img(.*)/([a-zA-Z0-9-_\.]*)\.([^/]+)\.([a-z]{2,4})

我创建了这个.htaccess：

RewriteCond assets/img$1/.$2.$4/$3.$4 -s
RewriteRule ^assets/img(.*)/([a-zA-Z0-9-_\.]*)\.([^/]+)\.([a-z]{2,4})$ assets/img$1/.$2.$4/$3.$4 [NC,L,QSA]
RewriteRule ^assets/img(.*)/([a-zA-Z0-9-_\.]*)\.([^/]+)\.([a-z]{2,4})$ assets/img/image.php?path=$1&file=$2.$4&key=$3&ext=$4 [NC,L,QSA]

没有RewriteCond的请求，其中存在重写的位置，正常工作。对于那些感兴趣的人，我的完整.htaccess发布在这里：http://pastie.org/1293667

问题是RewriteCond仅适用于紧随其后的规则，因此您的第二个RewriteRule始终会运行。一个解决方案is to negate the test you are making, then have the next command skip the two commands you want to run。

RewriteCond %{DOCUMENT_ROOT}assets/img$1/.$2.$4/$3.$4 !-f
RewriteRule . - [S=2]
RewriteRule ^assets/img(.*)/([a-zA-Z0-9-_\.]*)\.([^/]+)\.([a-z]{2,4})$ assets/img$1/.$2.$4/$3.$4 [NC,QSA]
RewriteRule ^assets/img(.*)/([a-zA-Z0-9-_\.]*)\.([^/]+)\.([a-z]{2,4})$ assets/img/image.php?path=$1&file=$2.$4&key=$3 [NC,L,QSA]

RewriteCond总是验证为false
