IIS URL重写默认语言路径

问题描述：

我正在尝试使一条规则起作用，从而使语言标识符位于url路径中.如果未指定语言，我们希望将网址强制为en版本.例如:

I'm trying to get a rule working whereby the language identifier is in the url path. We want to force the url to the en version if a language is not specified. For example:

www.domain.com/page.aspx应该重定向到www.domain.com/en/page.aspx

www.domain.com/page.aspx should redirect to www.domain.com/en/page.aspx

这是我们到目前为止的规则，但是它一直以重定向循环结尾.

Here's the rule we have so far, but it keeps ending up in a redirect loop.

<rule name="Default Language" stopProcessing="true">
        <match url="(.*)" />
        <conditions>                
            <add input="{REQUEST_URI}" pattern="^/(en|es|ph)/" negate="true" ignoreCase="true" />
        </conditions>
        <action type="Redirect" url="/en/{R:1}" redirectType="Permanent" />
    </rule>

有什么想法要去哪里吗?

Any ideas where it's going wrong?

答

将规则更改为:

<rule name="Default Language" stopProcessing="true">
    <match url="^en/" negate="true" />
    <action type="Redirect" url="/en/{R:0}" redirectType="Permanent" />
</rule>

它将检查url是否以 en/开头，如果不是，它将在请求的路径前面附加 en/.

It will check if the url starts with en/ and if not, it will append en/ in front of the requested path.

您进行了无限重定向，因为无论向哪个反向引用发送到/en/{R:1} ，它都与(.*)匹配(因为它与任何内容都匹配)/一切).

You had an infinite redirection because whatever back reference was sent to /en/{R:1}, it was matching (.*) (as it matches anything/everything).
