在IIS的高版本下面可以配置web.Config，在中间添加rewrite节点：

加在 <system.webServer>里面就可以了

<rewrite>
<rules>
<rule name="OrgPage" stopProcessing="true">
<match url="^(.*)$" />
<conditions logicalGrouping="MatchAll">
<add input="{HTTP_HOST}" pattern="^(.*)$" />
<add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
<add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
</conditions>
<action type="Rewrite" url="index.php/{R:1}" />
</rule>
</rules>
</rewrite>

我的最终配置

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <system.webServer>
        <defaultDocument>
            <files>
                <add value="index.php" />
            </files>
        </defaultDocument>
        <handlers>
            <remove name="php" />
            <add name="php" path="*.php" verb="*" modules="FastCgiModule" scriptProcessor="D:\phpstudy_pro\Extensions\php\php7.0.9nts\php-cgi.exe" resourceType="File" requireAccess="Script" />
        </handlers>
		<rewrite>
		 <rules>
		 <rule name="OrgPage" stopProcessing="true">
		 <match url="^(.*)$" />
		 <conditions logicalGrouping="MatchAll">
		 <add input="{HTTP_HOST}" pattern="^(.*)$" />
		 <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
		 <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
		 </conditions>
		 <action type="Rewrite" url="index.php/{R:1}" />
		 </rule>
		 </rules>
		 </rewrite>
    </system.webServer>
</configuration>
