URL重写规则-用于查询字符串值的子文件夹 [英] URL Rewrite rule - subfolder to query string value

问题描述

我正在尝试创建一条规则，该规则将从URL中获取子文件夹并将其转换为查询字符串值，例如:

I'm trying to create a rule the will take the subfolder from the URL and convert that to a query string value for example:

如果我导航到以下URL: http://www.example.com/myfolder 我想阅读 http://www.example.com/default.aspx?folder=myfolder

If I navigated to this URL: http://www.example.com/myfolder I would like that to read http://www.example.com/default.aspx?folder=myfolder

这是我要做的事情

<rule name="Rewrite Language">
  <match url="([a-z]{2})(.*)" />
  <conditions logicalGrouping="MatchAll">
    <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
    <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
  </conditions>
  <action type="Rewrite" url="/default.aspx?code={R:2}" />
</rule>

，但这不会返回完整的子文件夹值.老实说，我已经从本网站的类似问题中偷了这本书，我必须承认我真的不知道这意味着什么！

but this doesn't return the full subfolder value. I'll be honest I've stole this from a similar issue from this site, and I must confess I really have no idea what it all means!

我可能以错误的方式处理此问题，我的问题是我不确定该子文件夹是什么，因为它是由一个随机的6个字符的字母数字值动态生成的.

I might be approaching this in the wrong way, my issue is that I can't be sure what the subfolder will be as this is generated dynamically from a random 6 character alphanumeric value.

任何帮助将不胜感激.

推荐答案

IIS管理器具有GUI/向导界面，用于创建规则，与手动将规则输入到web.config文件中相比，通常我发现它更快捷，更容易.值得签出: IIS Manager->选择您的站点/应用程序->URL重写->添加规则.

The IIS Manager has a GUI / wizard interface for creating the rules which I usually find quicker and easier than entering the rule into the web.config file manually. Worth checking out: IIS Manager -> select your site / application -> URL Rewrite -> Add Rule(s).

我认为以下规则将为您解决问题:

I think the following rule will do the trick for you:

<rule name="RewriteUserFriendlyURL1" stopProcessing="true">
    <match url="^([^/]+)/?$" />
    <conditions>
        <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
        <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
    </conditions>
    <action type="Rewrite" url="default.aspx?folder={R:1}" />
</rule>

基本上，匹配网址"是正则表达式，用于标识其中的一部分网址.在这种情况下，它将捕获一个包含一个或多个字符(/除外)的组，并在URL的末尾带有一个可选的/.然后它将URL重写为 default.aspx?folder = ，后跟匹配的值( {R:1} 指第一个捕获的组，该组将包含文件夹名称).

Basically, the "match url" is a regular expression that is used to identify a part of the URL. In this case, it captures a group containing one or more characters (except for a /), with an optional / at the end of the URL. It will then rewrite the url to default.aspx?folder= followed by the value that was matched ({R:1} refers to the first captured group, which will contain the folder name).

这将起作用，前提是您只有一个子文件夹名称(而不是嵌套文件夹).

This will work provided you only have a single subfolder name (not nested folders).

您还可以添加第二条规则，该规则在相反的方向上起作用，因此浏览到 http://www.example.com/default.aspx?folder=myfolder 会导致用户看到 http://www.example.com/myfolder :

You could also add a second rule which works in the opposite direction, so browsing to http://www.example.com/default.aspx?folder=myfolder would result in the user seeing http://www.example.com/myfolder:

<rule name="RedirectUserFriendlyURL1" stopProcessing="true">
    <match url="^default\.aspx$" />
    <conditions>
        <add input="{REQUEST_METHOD}" pattern="^POST$" negate="true" />
        <add input="{QUERY_STRING}" pattern="^folder=([^=&amp;]+)$" />
    </conditions>
    <action type="Redirect" url="{C:1}" appendQueryString="false" />
</rule>
