.htaccess 写法问题

<IfModule mod_rewrite.c>
Options +FollowSymlinks -Multiviews

RewriteEngine On

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond $1 !^(index.php|images|robots.txt)
RewriteRule ^(.*)$ index.php/$1 [QSA,PT,L]

SetEnvIf Authorization .+ HTTP_AUTHORIZATION=$0
</IfModule>

index.php/$1 这种写法有时会报错，更改为下方代码:
<IfModule mod_rewrite.c>
Options +FollowSymlinks -Multiviews

RewriteEngine On

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond $1 !^(index.php|images|robots.txt)
RewriteRule ^(.*)$ index.php?/$1 [QSA,PT,L]

SetEnvIf Authorization .+ HTTP_AUTHORIZATION=$0
</IfModule>
