RewriteCond 验证始终为 false
我的 RewriteRule 中有一个正则表达式，目前运行良好。其次，我想测试该文件（请求被重写的位置）是否存在。因此，我在规则之前放置了 RewriteCond，但不幸的是，它始终验证为 false。
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（重写位置存在）正常工作。对于那些感兴趣的人，我完整的 .htaccess 发布在这里：http://pastie.org/1293667
I have a regular expression in my RewriteRule, which is currently working fine. Secondly I'd like to test wheter the file (where the request is rewritten at) exists. Therefore I placed a RewriteCond before my rule, but it validates always to false, unfortunately.
This is my regex:
assets/img(.*)/([a-zA-Z0-9-_\.]*)\.([^/]+)\.([a-z]{2,4})
And I created this .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]
A request without the RewriteCond, where the rewritten location exists, is working normally. For those who're interested, my complete .htaccess is posted here: 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始终运行。一种解决方案是否定您正在进行的测试，然后让下一个命令跳过您要运行的两个命令。The problem is that a
RewriteCondonly applies to the rule immediately following it, so your secondRewriteRuleis always run. One solution is to negate the test you are making, then have the next command skip the two commands you want to run.
