yii2开发总结(一)

为什么80%的码农都做不了架构师？>>>   

使用yii2的基础版本进行开发。

 

1. 部署

    runtimePath 如果有修改  需要 在config/web.php 中置顶新路径  并且确保此路径具有读写权限

    应用的静态文件  AppAsset  会在模板布局中使用   也需要保证 web/assets 具有读写权限。

    vendorPath  如果依赖的yii2框架文件目录发生变化   需要在 config/web.php  中指定新的 vendorPath 路径

index.php

<?php

// comment out the following two lines when deployed to production
defined('YII_DEBUG') or define('YII_DEBUG', true);
defined('YII_ENV') or define('YII_ENV', 'dev');

defined('YII_VENDOR_PATH') or define('YII_VENDOR_PATH', '/xxx/xxx/xxx/yii2/2.0.9');

require(YII_VENDOR_PATH . '/autoload.php');
require(YII_VENDOR_PATH . '/yiisoft/yii2/Yii.php');

$config = require(__DIR__ . '/../config/web.php');

(new yii\web\Application($config))->run();

   

$config = [

    'params' => require(__DIR__ . '/params.php'),
    //运行环境路径指到公共目录，否则在@app/runtime 并且有写入权限
    'runtimePath'=>'app\runtime',
    'vendorPath'=>YII_VENDOR_PATH, //如果此路径有变更，必须要在这里配置，否则会出错误
];

 

 

2. 代码

    编写统一的基础展示对象，提供带参数的构造函数和parse方法 填充对象数据。   

namespace app\vo;

use yii;

class BaseVo extends  yii\base\Object{

    function __construct(array $data=NULL)
    {
        if(!empty($data) && is_array($data)){
            foreach ($data as $name => $value) {
                if ($this::hasProperty($name)) {
                    $this->$name = $value;
                }
            }
        }
    }

    public function parse(array $data){
        if(!empty($data) && is_array($data)){
            foreach ($data as $name => $value) {
                if ($this::hasProperty($name)) {
                    $this->$name = $value;
                }
            }
        }
    }

}

 

统计的API接口输出类     共有属性可以在json格式化时输出，私有属性不会输出。

<?php

namespace app\common;

use yii;
use yii\helpers\Json;
