java - Tuckey UrlRewrite 中的正则表达式

Question

我正在使用Tuckey URLRewrite我需要一个接受除“/”或“\”之外的所有内容的规则

我已经编写了一条规则，但 tuckey 显示无休止的异常并且不加载页面

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

来自regexr我已经验证这个表达式“([^/\n\]+)”将选择除“/”或“\”之外的所有内容，但我遇到了异常。我错过了什么吗？

以下是异常(exception)情况:

Answer 1

OP 有这样的规则:

<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> 

显然，问题出在规则的排序上。由于第一个模式: ^/post 会覆盖以 /post 开头的任何内容，并导致以下模式，例如 ^/post/([^/]+)/type/([a-z]+)$ 完全被忽略。

这些规则需要像这样重新排序:

<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> 

即将通用的包罗万象的类型规则置于特定的目标规则之下。
