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
    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。

    code;    }    /**     * @param mixed $code     */    public function setCode($code)    {        $this->code = $code;    }    /**     * @return mixed     */    public function getMsg()    {        return $this->msg;    }    /**     * @param mixed $msg     */    public function setMsg($msg)    {        $this->msg = $msg;    }    /**     * @return mixed     */    public function getStartTime()    {        return $this->start_time;    }    /**     * @param mixed $start_time     */    public function setStartTime($start_time)    {        $this->start_time = $start_time;    }    /**     * @return mixed     */    public function getEndTime()    {        return $this->end_time;    }    /**     * @param mixed $end_time     */    public function setEndTime($end_time)    {        $this->end_time = $end_time;    }    /**     * @return mixed     */    public function getData()    {        return $this->data;    }    /**     * @param mixed $data     */    public function setData($data)    {        $this->data = $data;    }	/**	 * 初始化，根据参数返回输出类型	 */	public function __construct() {		//检查设置		$callback = Yii::$app->request->get('callback');		$varName = Yii::$app->request->get('varname');				switch (true) {			case !is_null($callback):				if (preg_match("/^[a-zA-Z][a-zA-Z0-9_\.]+$/", $callback)) {					$this->setReturnTypeJsonp($callback);					break;				}else{					//输出错误				}			case !is_null($varName):				if (preg_match("/^[a-zA-Z][a-zA-Z0-9_\.]+$/", $callback)) {					$this->setReturnTypeJsVar($varName);					break;				}else{					//输出错误				}			default:				$this->setReturnTypeJson();				break;		}        $this->start_time=time();	}	/**	 * 	 */	public function setReturnTypeJsVar($varName){		$this->resultFormat = 'jsvar';		$this->reaultVarName = $varName;	}		/**	 * 	 */	public function setReturnTypeJson(){		$this->resultFormat = 'json';	}		/**	 * 	 */	public function setReturnTypeJsonp($callback){		$this->resultFormat = 'jsonp';		$this->resultCallBack = $callback;	}		/**	 * 	 */	private function toJson (){		return Json::encode($this,JSON_UNESCAPED_UNICODE);	}		/**	 * 返回jsonp形式	 * var a = {};	 */	private function toJsonp (){				return htmlentities($this->resultCallBack).'('.Json::encode($this,JSON_UNESCAPED_UNICODE).');';	}		/**	 * 返回js变量形式	 * var a = {};	 */	private function toJsVar (){		return 'var '.htmlentities($this->resultCallBack).'='			.
