先看我遇到的问题:试图使用如下rewrite代码
RewriteEngine On
RewriteBase /dex/
RewriteRule ^wsdl/(sjz|bd|qhd|common)/?$ wsdl.php?u=$1 [L]
RewriteRule ^wsdl/?$ wsdl.php [L]
达到以下转换效果:
wsdl/sjz –> wsdl.php?u=sjz
wsdl/ –> wsdl.php
但天不随人愿,第二行转换效果没问题,第一行转换效果总是出不来,查了一下RewriteLog,有一句引起了我的注意:
(1) pass through /dex/wsdl/sjz
(3) [per-dir E:/cvswork/2005dex/] add path info postfix: E:/cvswork/2005dex/wsdl.php -> E:/cvswork/2005dex/wsdl.php/sjz
注意看第二句,它怎么把wsdl/sjz转换成了wsdl.php/sjz?难道和第二句RewriteRule有关?试着把第二句RewriteRule关掉,问题依旧。
于是祭起Google海搜,发现有人和我遇到了同样的问题:
the problem lies in here somewhere
with URL http://localhost/index/q we get:-
add path-info postfix: c:/wwwroot/index.php -> c:/wwwroot/index.php/q
strip per-dir prefix: c:/wwwroot/index.php/q -> index.php/q
applying pattern ‘^([^/.]*)$’ to uri ‘index.php/q’
I dont want index.php/q though!!!!! argghhhhh!!!
……
GOT IT!!!!!!!
Bl**dy windows OS
i removed the .htaccess file and http://localhost/phpinfo/x was still doing phpinfo.php
I added a directory called phpinfo and it worked - giving a directory listing
I re-created the .htaccess and voila it worked.
So basically if a directory doesnt exist it looks for a script (.php .html) and then uses that with further parameters sdded to the end of it.
I have to find a workaround for that now.
原来,是Apache在当前目录下找到了wsdl.php(依据wsdl/sjz中的wsdl),并且来了个狸猫换太子,继续搜索……终于在这个德语网页找到了答案:
MultiViews-option abschalten.
wenn diese aktiviert ist, würde ein request nach /kategorie auch kategorie.php finden, und das kollidiert natürlich mit deiner RewriteRule, weil dort eben mit /kategorie/irgendwas ebenfalls ein “treffer” vorliegt - da kann der server also nicht entscheiden, was jetzt eigentlich gemeint ist.
上面是德语,我是看不懂的,用Google翻译如下:
MultiViews option switch off.
if this is activated, after/category kategorie.php to also find request, and collides naturally with your RewriteRule, because evenly with/category/something is likewise present there a “hit” - there the server cannot decide thus, what is now actually meant.
原来是Apache的MultiViews选项干扰了RewriteRule,将其去掉之后,问题排除。
Options -MultiViews
继续寻找MultiViews的相关信息,收获如下:
* Beware of Apache’s Multiviews
* 内容协商(Apache手册中文版mod_negotiation部分)
所以,在没有明确需要的情况下,一般不要打开MultiViews选项,因为我们一般编写的程序很少用到它,反而会给正常的程序调试带来麻烦,另外早期的版本可能还存在一些安全问题。
在去掉MultiViews的同时,发现还有一个好像也没有用的Options——FollowSymLinks,但如果你的 RewriteRule是写在.htaccess文件中的话,FollowSymLinks这个选项可不能去掉,去掉了RewriteEngine就不干活啦~~
