How to implement a PHP Framework series article "4" URL routing management

Access functions ($ACT) in the controller ($CTL) in the Business module ($APP) directly via the URL parameter

We support 3 modes of routing

Normal Mode

_a= $app, _u= $ctl. $act

The simplest way to focus on implementing the business $act function, no need to write extra code

Why does the parameter name need to be underlined before it is explained?

Easy Mode

_easy= $app. $tpl. $ctl. $act

_easy= $app. $ctl. $act

In web development, we typically output a front-end page in $act,

In easy mode, if the $act handler function is not implemented, the corresponding front-end template file is automatically found and displayed.

For simple presentation pages, this routing pattern is suitable for use

URL Rewrite mode (requires Nginx or Apache configuration)

Apache: ^rewrite[\.\/] (. *) $/index.php?_rewrite=$1 [R,QSA]

Nginx:rewrite ^/rewrite[\.\/] (. *) $/index.php?_rewrite=$1 last;

Rewrite. {$app}. {$ctl}. {$act}. {$params}.html

Or a more elegant directory-access approach

rewrite/{$app}/{$ctl}/{$act}/{$params}.html

Where $params is the optional Parameters section. parameter list after format UrlEncode

If you want to pass SP_UID=1&D=1.2&P=SB, then $params = SP_UID%3D1%26D%3D1.2%26P%3DS%2FB

or SP_UID/1/D/1.2/P/SB

This mode can be used in certain scenarios where the URL cannot have?& special characters

1. In order to be able to pass QQ OAUTH2 login verification, need to configure rewrite rules

rewrite.thirdlogin.index.qqcallback.sp_uid%3d1.php

2. Resource static

Rewrite.upload.index.out.uidm%3d310ef4b.png

3. Payment Callback

rewrite.pay.weixin.native2_notify.php

4. Open platform Authorization callback

rewrite/web/component/message/_app_id/xxxxxxx.php

URL Rewrite mode if (! empty ($_request [' _rewrite ']) && is_string ($_request [' _rewrite '])) { 1. Support for Apache rewrite mode, after the missing parameter condition if (Stripos ($_server [' Server_software '], ' nginx ') = = = = False) { $_request [' _rewrite '] = UrlDecode (substr ($_server [' query_string '], strlen (' _rewrite= '))); } 2. Discard the suffix name in the _rewrite $rewrite = substr ($_request [' _rewrite '], 0, Strrpos ($_request [' _rewrite '], '. ')); 3. Support/As Delimiter $sp = '.
