官方默认提供了.htaccess文件，不过这个文件仅能在Apache环境下生效，如果您的WEB服务器使用的IIS，那么伪静态规则需要做一些修改或调整。
首先需要确保的是您的ThinkPHP URL模式为2，然后添加下面的规则。
IIS 6规则
[ISAPI_Rewrite]
# Defend your computer from some worm attacks
RewriteCond %{REQUEST_URI} !^.*(.css|.js|.gif|.png|.jpg|.jpeg|.xml|.php)
RewriteRule .*(?:global.asa|default\.ida|root\.exe|\.\.).* . [F,I,O]
RewriteRule (?!/index.php)(?!/admin.php)(?!/Admin/)(?!/Public/)(?!/install/)(?!/404/)(?!/plugin/)(?!/css/)(?!/images/)(?!/js/)(.*)$ /index.php?s=$1 [I]IIS 7规则
将下面的配置文件添加到web.config文件中:
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>
<rewrite>
<rules>
<rule name="OrgPage" stopProcessing="true">
<match url="^(.*)$" />
<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>
