当URL包含特殊字符时,我的重写规则出错:
此网址http://www.example.com/bungalow/rent/state/texas/street/exloër/exloër 使用此重写规则:
<rule name="rentals by proptype+state+city+street">
<match url="^([a-zA-Z0-9-+]+)/rent/state/([a-zA-Z-+]+)/street/([a-zA-Zë-+]+)/([0-9a-zA-Zë-+']+)$" />
<action type="Rewrite" url="search_new.aspx?proptype={R:1}&state={R:2}&city={R:3}&street={R:4}" />
</rule>
导致500错误
此网址http://www.example.com/bungalow/rent/state/texas/street/exloër/exloër 使用此重写规则:
<rule name="rentals by proptype+state+city+street">
<match url="^([a-zA-Z0-9-+]+)/rent/state/([a-zA-Z-+]+)/street/([a-zA-Z-+]+)/([0-9a-zA-Z-+']+)$" />
<action type="Rewrite" url="search_new.aspx?proptype={R:1}&state={R:2}&city={R:3}&street={R:4}" />
</rule>
导致404错误
如何处理重写规则中的特殊字符?
更新1
相关网址带有ë
字符,但是当我复制地址时,它会转义为%c3%abr
根据此规则,我仍然会收到404错误:
<rule name="rentals by proptype+state+city+street">
<match url="^([a-zA-Z0-9-+]+)/rent/state/([a-zA-Z-+]+)/street/([a-zA-Z%-+]+)/([0-9a-zA-Z%-+']+)$" />
<action type="Rewrite" url="search_new.aspx?proptype={R:1}&state={R:2}&city={R:3}&street={R:4}" />
</rule>
所以我想真正的问题是,如何在重写规则中处理%
个字符?
答案 0 :(得分:2)
你的最后一次尝试几乎是正确的正则表达式,你只有一个小错误(忘了添加0-9到第三个块)。正确的正则表达式是:
^([a-zA-Z0-9-+]+)/rent/state/([a-zA-Z-+]+)/street/([a-zA-Z0-9%-+]+)/([0-9a-zA-Z%-+']+)$
但在重写规则中,您需要使用变量{UNENCODED_URL}
。
工作示例是:
<rule name="rentals by proptype+state+city+street" stopProcessing="true">
<match url=".*" />
<conditions>
<add input="{UNENCODED_URL}" pattern="^/([a-zA-Z0-9-+]+)/rent/state/([a-zA-Z-+]+)/street/([a-zA-Z0-9%-+]+)/([0-9a-zA-Z%-+']+)$" />
</conditions>
<action type="Rewrite" url="search_new.aspx?proptype={C:1}&state={C:2}&city={C:3}&street={C:4}" />
</rule>
<强> UPD 强>
来自评论的例子:
您的网址:http://www.example.com/bungalow/rent/state/north-dakota/stre et / savanah /%27s-gr acland有一些隐藏的特殊字符(即使SO无法正确解析它)。您可以在此处查看其编码方式:https://www.urlencoder.org/。
因此我更改了规则中的正则表达式,如下所示:
<rule name="rentals by proptype+state+city+street" stopProcessing="true">
<match url=".*" />
<conditions>
<add input="{UNENCODED_URL}" pattern="^/([a-zA-Z0-9\-+]+)/rent/state/([a-zA-Z\-+]+)/([a-zA-Z0-9%\-+]+)/([a-zA-Z0-9%\-+]+)/([0-9a-zA-Z%\-+']+)$" />
</conditions>
<action type="Rewrite" url="search_new.aspx?proptype={C:1}&state={C:2}&city={C:4}&street={C:5}" />
</rule>
