How to implement a php framework article series [4] url routing management-php Tutorial

How to implement a php framework article series [4] url routing management directly accesses functions ($ act) in the controller ($ ctl) of the business module ($ app) through url parameters)

We support three routing modes

Normal mode

_ A = $ app, _ u = $ ctl. $ act

The simplest way is to focus on implementing the business $ act function without writing additional code.

Why do we need to underline the parameter name?

Easy Mode

_ Easy = $ app. $ tpl. $ ctl. $ act

_ Easy = $ app. $ ctl. $ act

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

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

This routing mode is suitable for simple display pages.

Url rewriting mode (nginx or apache configuration is required)

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

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

Rewrite.{$app}.{$ctl).{actact).{params).html

Or more elegant Directory-based access

Rewrite/{$ app}/{$ ctl}/{$ act}/commandid params0000.html

$ Params is the optional parameter. list of parameters in urlencode format

To pass sp_uid = 1 & d = 1.2 & p = sb, $ params = sp_uid % 3D1% 26d % 3D1. 2% 26 p % 3Ds % 2Fb

Or sp_uid/1/d/1.2/p/sb

Which of the following cannot be included in some required URLs? & This mode can be used for special characters

1. in order to pass the qq oau2's login verification, you need to configure rewrite rules

Rewrite. thirdlogin. index. qqcallback. sp_uid % 3D1. php

2. static resources

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

3. payment callback

Rewrite. pay. weixin. native2_policy.php

4. open platform authorization callback

Rewrite/web/component/message/_ app_id/xxxxxxx. php
