php7.2 fastcgi环境配置伪静态？

新人求教各位大侠们，我用php7.2 + fastcgi环境配置了一个网站，开启伪静态的时候难倒了……
 我把web.config文件，上传到我的服务器根目录下，显示config文件第22行报错。
  代码如下：

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <system.webServer>
        <rewrite>
            <rules>
                <rule name="yhxia_page" 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>
  <httpErrors errorMode="Detailed" />
  <asp scriptErrorSentToBrowser="true" />
  </system.webServer>
<system.web>
<customErrors mode="Off" />
<globalization requestEncoding="utf8" responseEncoding="utf8" fileEncoding="utf8" />
</system.web>
</configuration>

请各位大侠们帮忙指教
