写接口经常用到代码片段

1.复制代码放在tp框架extend/service 文件夹中
2 在使用的控制器中 use service\JsonService; 引入
3.使用如下
return JsonService::successful(“评论成功”);
return JsonService::fail(“评论失败”);
4 设置返回数据
return JsonService::returnData(code,msg’,$data);

 * @param int $code 响应code
 * @param string $msg 提示语
 * @param array $data 返回数据
 * @return array

namespace service;


class JsonService
{
    private static $SUCCESSFUL_DEFAULT_MSG = 'ok';

    private static $FAIL_DEFAULT_MSG = 'no';

    public static function result($code,$msg='',$data=[],$count=0)
    {
        exit(json_encode(compact('code','msg','data','count')));
    }
    public static function successlayui($count=0,$data=[],$msg='')
    {
        if(is_array($count)){
            if(isset($count['data'])) $data=$count['data'];
            if(isset($count['count'])) $count=$count['count'];
        }
        if(false == is_string($msg)){
            $data = $msg;
            $msg = self::$SUCCESSFUL_DEFAULT_MSG;
        }
        return self::result(0,$msg,$data,$count);
    }
    public static function successful($msg = 'ok',$data=[],$status=200)
    {
        if(false == is_string($msg)){
            $data = $msg;
