在网站根目录新建web.config文件，加入如下代码：

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
  <system.webServer>
    <rewrite>
      <rules>
        <rule name="category">
          <match url="category/?(.*)" />
          <conditions logicalGrouping="MatchAll" trackAllCaptures="false" />
          <action type="Rewrite" url="/index.php?category_name={R:1}" appendQueryString="false" logRewrittenUrl="false" />
