我们支持3种路由模式
普通模式
_a=$app, _u=$ctl.$act
最简单的方式,专注实现业务$act函数,不需要再写额外代码
为什么参数名前面要加下划线就不解释了
easy模式
_easy=$app.$tpl.$ctl.$act
_easy=$app.$ctl.$act
在web开发中,通常我们在$act中输出一个前端页面,
easy模式下,如果未实现$act处理函数,会自动寻找并显示对应的前端模板文件。
对于简单的展示页面适合使用这种路由模式
url重写模式(需要nginx或apache配置)
apache: ^rewrite[\.\/](.*)$ /index.php?_rewrite=$1 [R,QSA]
nginx: rewrite ^/rewrite[\.\/](.*)$ /index.php?_rewrite=$1 last;
rewrite.{$app}.{$ctl}.{$act}.{$params}.html
或更加优雅的目录式访问方式
rewrite/{$app}/{$ctl}/{$act}/{$params}.html
其中$params为选填参数部分.格式为urlencode后的参数列表
如果想传递sp_uid=1&d=1.2&p=sb, 那么$params = sp_uid%3D1%26d%3D1.2%26p%3Ds%2Fb
或sp_uid/1/d/1.2/p/sb
在某些要求url中不能带?&特殊字符的场景下可以使用这种模式
1. 为了能通过qq oauth2登陆验证,需要配置重写规则
rewrite.thirdlogin.index.qqcallback.sp_uid%3D1.php
2. 资源静态化
rewrite.upload.index.out.uidm%3D310ef4b.png
3. 支付回调
rewrite.pay.weixin.native2_notify.php
4. 微信开放平台授权回调
rewrite/web/component/message/_app_id/xxxxxxx.php
