基础版配置 web.php
高级版配置 main.php

1. 资源装配

/assets/AppAsset.php

２.入口index.php配置　

/web/index.php配置

3. 配置数据库

３.１系统默认配置

　　　/config/db.php
   return [
        'class' => 'yii\db\Connection',
        'dsn' => 'mysql:host=localhost;dbname=yii2basic',
        'username' => 'root',
        'password' => '',
        'charset' => 'utf8',
    ];

　３.２常用数据库配置

　　　   /config/db.php
   return [
        'class' => 'yii\db\Connection',
        //'dsn' => 'mssql:host=localhost;dbname=shop_obd2', // MySQL, MariaDB
        //'dsn' => 'sqlite:/path/to/database/file', // SQLite
        //'dsn' => 'pgsql:host=localhost;port=5432;dbname=mydatabase', // PostgreSQL
        //'dsn' => 'cubrid:dbname=demodb;host=localhost;port=33000', // CUBRID
        'dsn' => 'sqlsrv:Server=184.168.194.53;Database=xms_mbstarshop', // MS SQL Server, sqlsrv driver

        'password' => ' ',
        'charset' => 'utf8',
        //'tablePrefix' => 'tb_',
    ];

４.ＷＥＢ应用配置config/web.php

4.1　别名配置

　　'aliases' => [
   　　　 '@name1' => 'path/to/path1',        // @xxx 表示别名
　　　    '@name2' => 'path/to/path2',
　　   ],

　4.2 修改布局模板

　　　--- 框架默认定义 ---

　　　yii2/base/application.php
　 public $layout = 'main';

--- 自定义配置 ---

            /config/web.php
            'layout' => 'main',
    4.3　修改默认路由

　　--- 框架默认路由 ---

yii2/web/application.php
public $defaultRoute = 'site';

--- 自定义修改路由 ---

/config/web.php
'defaultRoute' => 'index',

4.4 配置路由 ( 配置reUrl, 和 /config/web.php　只能二选一，否则其中一个不工作)

4.4.1 /config/web.php配置

　　'urlManager' => [
            'showScriptName' => false,   // Disable index.php
            'enablePrettyUrl' => true,   // Disable r= routes
            'enableStrictParsing' => false,
            'rules'=>array(
                [
                'pattern' => 'test/about',
                'route' => 'site/about',
                //'suffix' => '.do',
                ],
                'wholesale/<title:\w+>'=>'site/<title>',
            '<controller:\w+>/<action:\w+>/<id:\d+>'=>'<controller>/<action>',
            '<controller:\w+>/<action:\w+>'=>'<controller>/<action>',
             ),

        ],

4.4.2 在/web/.htaccess

      Options FollowSymLinks
      RewriteEngine on
      RewriteRule test/abc.do$ index.php?r=/site/contact [L]
      RewriteCond %{REQUEST_FILENAME} !-f
      RewriteRule !\.(js|ico|txt|gif|jpg|png|css|html|xml)$ /index.php
      Options -Indexes

4.5 设置Cookie加密key

         /config/web.php
         'components' => [
             'request' => [
                // !!! insert a secret key in the following (if it is empty) - this is required by cookie validation
                'cookieValidationKey' => 'life2015',
             ],

５. 资源装配配置

　 5.1 /assets/AppAsset.php
    public $css = [
        'css/site.css',        //附加到header
    ];
    public $js = [
                    //'test/test1.js',默认应用根目录前缀：/web/ ，附加到footer
    ];　

5.2 --- 在视图脚本中注册，调用 ---

    方法一
    AppAsset::register($this);   //调用已资源管理器中已配置的文件
    ?>
    <?php $this->beginPage() ?>
    <!DOCTYPE html>
    <html lang="<?= Yii::$app->language ?>">
        <head>
        ...
        </head>
        <body>
        <?php $this->beginBody() ?>
        ...

<?php $this->endBody() ?>    
    </body>
    </html>
    <?php $this->endPage() ?>

方法二，注册文件

$this->registerJsFile('abc.js'); //加载在尾部，但在jquery.js之前
$this->registerJsFile('aaa.js', ['depends' => 'app\assets\AppAsset']); //加载在jquery.js之后

方法三，注册 code block

可以直接写脚本，或

<?php$this->beginBlock('test')?>

$(function($){

$('#mybutton').click(function(){

alert('OK');

});

<?php$this->endBlock()?>

<?php$this->registerJs($this->blocks['test'], \yii\web\View::POS_END); ?>

$this->registerJs($this->blocks['test']); //加载在尾部，但在jquery.js之前
$this->registerJs($this->blocks['test'], ['depends' => 'app\assets\AppAsset']); //加载在jquery.js之后

6. /config/params.php 配置参数：
　　\Yii::$app->params['recentPosts']

--- 在控制器中修改视图中的 $this->title
\Yii::$app->view->title= 'from controller abc';
