使所有js和css文件通过php
我有一个不启用使所有js和css文件通过php,php,.htaccess,Php,.htaccess,我有一个不启用mod\u expires的共享主机。所以我试图让我所有的CSS和JS文件通过一个PHP文件,该文件添加了一个必需的头,但我无法让它工作。我试过上面给出的解决办法 我有以下资料: .htaccess: RewriteEngine On RewriteCond %{QUERY_STRING} base64_encode[^(]*\([^)]*\) [OR] RewriteCond %{QUERY_STRING} (<|%3C)([^s]*s)+cript.*(>|%3E
mod\u expires
的共享主机。所以我试图让我所有的CSS和JS文件通过一个PHP文件,该文件添加了一个必需的头,但我无法让它工作。我试过上面给出的解决办法
我有以下资料:
.htaccess:
RewriteEngine On
RewriteCond %{QUERY_STRING} base64_encode[^(]*\([^)]*\) [OR]
RewriteCond %{QUERY_STRING} (<|%3C)([^s]*s)+cript.*(>|%3E) [NC,OR]
RewriteCond %{QUERY_STRING} GLOBALS(=|\[|\%[0-9A-Z]{0,2}) [OR]
RewriteCond %{QUERY_STRING} _REQUEST(=|\[|\%[0-9A-Z]{0,2})
RewriteRule .* index.php [F]
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
RewriteCond %{REQUEST_URI} !^/index\.php
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule .* index.php [L]
RewriteRule ^(.*\.js) gzip.php?type=js&file=$1
RewriteRule ^(.*\.css) gzip.php?type=css&file=$1
重新编写引擎打开
RewriteCond%{QUERY\u STRING}base64\u encode[^(]*\([^)]*\)[或]
重写cond%{QUERY_STRING}(|%3E)[NC,或]
重写条件%{QUERY\u STRING}全局(|\[|\%[0-9A-Z]{0,2})[或]
重写条件%{QUERY\u STRING}\u请求(|\[|\%[0-9A-Z]{0,2})
重写规则。*index.php[F]
重写规则。*-[E=HTTP\U授权:%{HTTP:AUTHORIZATION}]
重写cond%{REQUEST_URI}!^/index\.php
重写cond%{REQUEST_FILENAME}!-f
重写cond%{REQUEST_FILENAME}!-d
重写规则。*index.php[L]
重写规则^(.*\.js)gzip.php?type=js&file=1
重写规则^(.*\.css)gzip.php?type=css&file=1
