正则表达式在Tuckey UrlRewrite

Question

我是新手在正则表达式，所以请裸露在我身边。我使用Tuckey URLRewrite，我需要它接受除了“/”或“\”一切规则

我已经写了一个规则，但tuckey显示无休止的异常，不加载页面

<rule> 
     <from>^/post/([^/\n\\]+)/type/([a-z]+)$</from> 
     <to>/post/?slug=$1&amp;type=$2</to> 
    </rule> 

从regexr我已经验证了这个表达式“（[^/\ n \] +）”会选择除“/”或“\”之外的所有内容，但是我收到了异常。我错过了什么吗？

这里是例外：

Answer 1

OP有过这样的规则：

<rule> 
<from>^/post</from> 
<to>/post/</to> 
</rule> 

<rule> 
<from>^/post/([^/]+)</from> 
<to>/post/?slug=$1</to> 
</rule> 

<rule> 
<from>^/post/([^/]+)/type/([a-z]+)$</from> 
<to>/post/?slug=$1&amp;type=$2</to> 
</rule> 

问题显然是这里的排序规则。由于第一种模式：^/post覆盖任何以/post开头并导致像^/post/([^/]+)/type/([a-z]+)$之类的模式被完全忽略的任何内容。

这些规则需要重新排序是这样的：

<rule> 
<from>^/post/([^/]+)/type/([a-z]+)$</from> 
<to>/post/?slug=$1&amp;type=$2</to> 
</rule> 

<rule> 
<from>^/post/([^/]+)</from> 
<to>/post/?slug=$1</to> 
</rule> 

<rule> 
<from>^/post</from> 
<to>/post/</to> 
</rule> 

即保持低于特定目标的人一般捕获所有类型的规则。
