iis 重定向跳转到带www的域名的操作方法

考虑到用户体验，网站通常会一个跳转。比如我的网站域名是 liuhaolin.com ，网站的首页是 https://www.liuhaolin.com, 如果web服务器用的是iis，那么操作就比较简单。通常修改一下 web.config 文件就可以。

iis重定向到www的方法

在网站的更目录，添加一条规则

<rule name="Redirect to www" stopProcessing="true">
    <match url=".*" />
    <conditions>
        <add input="{HTTP_HOST}" pattern="^liuhaolin.com$" />
    </conditions>
    <action type="Redirect" url="https://www.liuhaolin.com/{R:0}" redirectType="Permanent" />
</rule>

类似的跳转，还有一个，就是 http 跳转到 https

<rule name="HTTP to HTTPS redirect" enabled="true" stopProcessing="true"><match url=".*" />
    <conditions logicalGrouping="MatchAll" trackAllCaptures="false">
    <add input="{HTTPS}" pattern="^OFF$" />
    </conditions>
    <action type="Redirect" url="https://{HTTP_HOST}/{R:0}" />
</rule>

iis中 wordpress 的重写规则

<rule name="WordPress" patternSyntax="Wildcard">
    <match url="*" />
    <conditions>
        <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
        <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
    </conditions>
    <action type="Rewrite" url="index.php" />
</rule>

已上，三条规则是在处理一个wordpress网站遇到的问题。总结一下，会贴出一个完整的配置

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
  <system.webServer>
    <rewrite>
        <rules>
            <rule name="Redirect to www" stopProcessing="true">
                <match url=".*" />
                <conditions>
                    <add input="{HTTP_HOST}" pattern="^liuhaolin.com$" />
                </conditions>
                <action type="Redirect" url="https://www.liuhaolin.com/{R:0}" redirectType="Permanent" />
            </rule>

            <rule name="HTTP to HTTPS redirect" enabled="true" stopProcessing="true"><match url=".*" />
                <conditions logicalGrouping="MatchAll" trackAllCaptures="false">
                <add input="{HTTPS}" pattern="^OFF$" />
                </conditions>
                <action type="Redirect" url="https://{HTTP_HOST}/{R:0}" />      
            </rule>

            <rule name="WordPress" patternSyntax="Wildcard">
                <match url="*" />
                <conditions>
                    <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
                    <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
                </conditions>
                <action type="Rewrite" url="index.php" />
            </rule>
        </rules>
    </rewrite>
  </system.webServer>
</configuration>
