Yii multi-application multi-module

This article takes YII 2.0.7 as an example to share with you about Yii multi-application and multi-module. Friends in need can refer to it

Overview

First look at multi-application and multi-module Features of the module:

Features of multiple applications:

• Independent configuration file

• Independent domain name

Features of multiple modules:

• Unified configuration file

• Unified domain name

So, how to actually decide whether to use multiple applications or multiple modules?

• For the separation of front and backend, for example, the backend needs a separate domain name for management. This should use multiple applications.

• The configuration of multiple applications is completely different. It is more convenient to use multiple applications. Use different configuration files

• Multiple applications require more domain name configurations, which makes price comparison troublesome. For small projects, domain names are not distinguished. Multiple modules are better

Multiple applications

The easiest way is to download the advanced application template of Yii2 from the official website: yii-advanced-app-2.0.12.tgz. After downloading and decompressing, enter the advanced directory and run:

# Windows
init.bat

# Linux
init

will open the web# of the two applications frontend and backend ##Directory generation entry file index.php. frontend and backend represent frontend and background applications respectively. The directory structure inside is the same:

assets/  
config/  
controllers/  
models/  
runtime/  
views/  
web/

Run:

$ cd advanced/frontend/web
$ php -S 0.0.0.0:8888
PHP 5.6.22 Development Server started at Sun Aug 20 21:10:28 2017
Listening on http://0.0.0.0:8888

Open the browser and enter http://0.0.0.0:8888 can access the default home page.

It is recommended that the model is placed in

common/models in the root directory.

Multiple modules

For multiple modules, please refer to

http://www.yiichina.com/doc/g.... Example: Create a new h5 application in frontend:

1. Create related directories

$ cd frontend
$ mkdir -p modules/h5 && cd modules/h5
$ mkdir controllers
$ touch Module.php

2.

Module. php Content example:

<?php
namespace frontend\modules\h5;

class Module extends \yii\base\Module
{
    public function init()
    {
        parent::init();

        $this->params[&#39;foo&#39;] = &#39;bar&#39;;
        // ...  其他初始化代码 ...
    }
}

3. Add module declaration in

frontend/config/main.php:

'modules' => [
    'h5' => [
        'class' => 'frontend\modules\h5\Module',
        // ... 模块其他配置 ...
    ],
],

4. In

modules/ h5/controllersNew controller class:

<?php
namespace frontend\modules\h5\controllers;

use Yii;
use common\models\LoginForm;
use frontend\models\SignupForm;
use frontend\models\ContactForm;
use yii\base\InvalidParamException;
use yii\web\BadRequestHttpException;
use yii\web\Controller;

class SiteController extends Controller
{
    public function actionIndex()
    {
        return "hello h5 module";
        //return $this->render(&#39;index&#39;);
    }
}

Browser access:

http://localhost:8888/index.php?r=h5/site/index to access .

There is another way to implement an access form similar to this URL route, such as

r=test/site/index. Just create a new subdirectory in the frontend/controllers directory called test, put the controller in it, and then change the namespace to

namespace frontend\controllers\test;

. This can be used for API version control, for example:

r=v1/site/index
r=v2/site/index
