在IIS7中重写映射 - 如何使匹配可选地包含尾部斜杠？ [英] Rewrite maps in IIS7 — how to make the match optionally include a trailing slash?

问题描述

我已经阅读了几个 IIS重写地图条件等组合的前30个Google点击次数，但我找不到任何体面的文档，无论是在microsoft.com网站还是其他地方。

I have read the top 30 Google hits for several combinations of IIS rewrite map condition and so on, but I can't find any decent documentation, either on a microsoft.com site or elsewhere.

我在IIS7中有一堆重写地图，我想处理它们，无论它们是否存在之后是斜线。所以 www.foo.com/bar 和 www.foo.com/bar / 都应符合规则。

I have a bunch of rewrite maps in IIS7 that I would like to process irrespective of whether or not they are followed by a trailing slash. So www.foo.com/bar and www.foo.com/bar/ should both match the rule.

<rewrite>
    <rewriteMaps>
        <rewriteMap name="ShortURLs">
            <add key="/terms" value="/en-us/terms-and-conditions/"/>
            <add key="/privacy" value="/en-us/privacy-and-cookies/"/>
            <add key="/buy" value="/en-us/where-to-buy/"/>
        </rewriteMap>
    </rewriteMaps>
    <rules>
        <rule name="Short URL redirects">
            <match url="^/?(.+)/?$" />
            <conditions>
                <add input="{ShortURLs:{REQUEST_URI}}" pattern="(.+)"/>
            </conditions>
            <action type="Redirect" url="{C:1}" appendQueryString="true"/>
        </rule>
    </rules>
</rewrite>

现在这个效果非常好，除了我能找到的唯一方法 / terms / 匹配重写映射中的第一个键是复制映射，使其显示为：

Now this works perfectly well, except that the only way I can find to make /terms/ match the first key in the rewrite map is to duplicate the map, so that it reads:

<rewriteMap name="ShortURLs">
    <add key="/terms" value="/en-us/terms-and-conditions/"/>
    <add key="/privacy" value="/en-us/privacy-and-cookies/"/>
    <add key="/buy" value="/en-us/where-to-buy/"/>

    <add key="/terms/" value="/en-us/terms-and-conditions/"/>
    <add key="/privacy/" value="/en-us/privacy-and-cookies/"/>
    <add key="/buy/" value="/en-us/where-to-buy/"/>
</rewriteMap>

考虑到我首先使用正则表达式来匹配它们，这看起来非常荒谬。将 /？添加到条件输入或条件模式似乎不起作用。

This seems ridiculously inelegant, given that I'm using regular expressions to match them in the first place. Adding /? to the condition input or the condition pattern doesn't seem to work.

我见过< a href =https://stackoverflow.com/a/13630398/205245>答案 IIS7重写地图正则表达式？提到正则表达式不能使用（引自在URL重写模块中使用重写映射）但是，正如我在那里评论的那样，这似乎与在该文本之前给出的具体示例有关，而不是批发这可以永远不会工作。

I have seen the answer to IIS7 Rewrite Map Regex? that mentions regular expressions cannot be used (quoting from Using Rewrite Maps in URL Rewrite Module) but, as I have commented there, this seems to relate to the specific examples being given before that text, rather than a wholesale "this can never work".

我缺少什么？必须有一些方法来做到这一点;我错过了一些明显的东西吗？

What am I missing? There must be some means of doing this; am I missing something obvious?

推荐答案

这应该这样做：

<rewrite>
    <rewriteMaps>
        <rewriteMap name="ShortURLs">
            <add key="terms" value="/en-us/terms-and-conditions/"/>
            <add key="privacy" value="/en-us/privacy-and-cookies/"/>
            <add key="buy" value="/en-us/where-to-buy/"/>
        </rewriteMap>
    </rewriteMaps>
    <rules>
        <rule name="Short URL redirects">
            <match url="^(.+?)/?$" />
            <conditions>
                <add input="{ShortURLs:{R:1}}" pattern="(.+)" />
            </conditions>
            <action type="Redirect" url="{C:1}" appendQueryString="true"/>
        </rule>
    </rules>
</rewrite>

你非常接近;我只需做三个小改动：

You were quite close; I only needed to make three small changes:

• 删除重写地图中键中的前导斜杠


• 在规则的匹配中使用了非贪婪量词 +？


• 使用了对匹配的后引用<$ c $条件输入中的c> {R：1}

• removed the leading slashes in the keys in the rewrite map
• used the non-greedy quantifier +? in the rule's match
• used a back reference to the match {R:1} in the condition input

我分享你在寻找体面方面遇到困难的经验文件;在以下文章的帮助下，我不得不试验一下：

I share your experience in having trouble finding decent documentation; I had to experiment my way through, with help from the following articles:
