Descrição
O arquivo thumb_handler.php é para ser usado como manipulador de páginas 404 para criar e transmitir miniaturas de imagens ainda não existentes.
To use it, follow the steps below, then set $wgGenerateThumbnailOnParse to false.
If you have $wgLocalFileRepo defined in LocalSettings.php, then you need to also set:
$wgLocalFileRepo['transformVia404'] = true;
Server configuration
The configuration below assumes you don't have custom file repos (at least $wgLocalFileRepo) configured manually. In that case, you will need to adjust the path of rewrite rules according to
$wgLocalFileRepo['hashLevels'] and $wgLocalFileRepo['deletedHashLevels'].Apache
Create a rewrite rule to call thumb_handler.php when a file in $wgUploadPath/thumb/ doesn't exist. If your wiki is in the /w directory, something like this should work for Apache:
If $wgHashedUploadDirectory is set to true:
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^/?w/images/thumb/[0-9a-f]/[0-9a-f][0-9a-f]/[^/]+/[^/]+$ /w/thumb_handler.php [L,QSA]
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^/?w/images/thumb/archive/[0-9a-f]/[0-9a-f][0-9a-f]/[^/]+/[^/]+$ /w/thumb_handler.php [L,QSA]
If $wgHashedUploadDirectory is set to false:
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^/?w/images/thumb/[^/]+/[^/]+$ /w/thumb_handler.php [L,QSA]
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^/?w/images/thumb/archive/[^/]+/[^/]+$ /w/thumb_handler.php [L,QSA]
nginx
location /w/images {
# Separate location for images/ so .php execution won't apply
location ~ ^/w/images/thumb/(archive/)?[0-9a-f]/[0-9a-f][0-9a-f]/([^/]+)/[^/]*([0-9]+)px-.*$ {
# Thumbnail handler for MediaWiki
# This location only matches on a thumbnail's url
# If the file does not exist we use @thumb to run the thumb.php script
try_files $uri $uri/ @thumb;
}
}
# Thumbnail 404 handler, only called by try_files when a thumbnail does not exist
location @thumb {
# Do a rewrite here so that thumb.php gets the correct arguments
rewrite ^/w/images/thumb/([0-9a-f]/[0-9a-f][0-9a-f]/([^/]+)/[^/]*([0-9]+)px-.*)$ /w/thumb_handler.php/$1;
