Regex .htaccess重写点/周期的url问题

Question

我打算重定向这个网址：

http://localhost/iiif/http/image-service/papyrus,1/full/400,300/0/default.jpg

至

http://localhost/iiif/http/image.php?req=763648&id=papyrus,1&region=full&size=400,300&rotation=0&quality=default&format=jpg

我把重写规则写成：

<IfModule mod_rewrite.c>
RewriteEngine on
RewriteBase /iiif/http/    
RewriteRule image-service/(.*)/(.*)/(.*)/(.*)/(.*).(.*)$ image.php?req=763648&id=$1&region=$2&size=$3&rotation=$4&quality=$5&format=$6 [R=301,NC,L,P]
</IfModule>

结果是：

Array
(
    [req] => 763648
    [id] => papyrus,1
    [region] => full
    [size] => 400,300
    [rotation] => 0
    [quality] => default.jp.
)

而不是：

Array
(
    [req] => 763648
    [id] => papyrus,1
    [region] => full
    [size] => 400,300
    [rotation] => 0
    [quality] => default
    [format] => jpg
)

我怀疑这是由于存在一个周期/点(.)在地窖里。我怎样才能改正呢？

Answer 1

您需要转义文件扩展名之前的句点。

/(.*)/(.*)/(.*)/(.*)/(.*)\.(.*)

注意最后两个\捕获组之间添加的反斜杠(.*)

Answer 2

我建议您使用这样的重写规则：

RewriteEngine on
RewriteBase /iiif/http/    
RewriteRule image-service/([^/]+)/([^/]+)/([^/]+)/([^/]+)/([^/.]+)\.(.*)$ image.php?req=763648&id=$1&region=$2&size=$3&rotation=$4&quality=$5&format=$6 [NC,L,QSA]

分解：

anything

• Removal

• 否定字符类[^/]+，而不是贪婪的.*，后者可能与重写时的R=301和P标志相匹配，因为您只需要一个内部的最后一点来匹配扩展
