3.2.1我发现有又拍云的上传驱动，所以把上传函数改造了一下以便于一次配置后可以自动判断上传
/*
自动获取上传配置上传函数
*/
function filed($config='',$path=''){
    $upload_type=c('upload_type');
    $upload_driver=c($upload_type);
    if (!$config) {
        $config = array(
        'maxsize'    =>    3145728,
        'rootpath'   =>    'upload',
        'savepath'   =>    $path,
        'savename'   =>    'time',
        'exts'       =>    array('jpg', 'gif', 'png', 'jpeg'),
        'autosub'    =>    true,
        'subname'    =>    array('date','ymd'),
        'replace'    =>     true,
        );
    }
    // 实例化上传类
    $upload = new \think\upload($config,$upload_type,$upload_driver);
    $path?true:$upload->savepath='/';
    $info   =   $upload->upload();          // 上传文件      
    if(!$info) {    
        $data['type']=0;
        $data['msg']=$upload->geterror();  
        return $data;   // 上传错误提示错误信息  
    }else{
        $request=array();
        foreach ($info as $key => $value) {
            $request[]=$value;
        }
        if ($upload_type!=='local') {
            for($i=0;$i            $res[]='http://'.c('files_domain').'/'.$config['rootpath'].$request[$i]['savepath'].$request[$i]['savename'];
            }
        }else{
            for($i=0;$i            $res[]=__root__.'/'.$config['rootpath'].$request[$i]['savepath'].$request[$i]['savename'];
            }
        }
        $data['type']=1;
        $data['msg']=$res;
        return $data;
    }
}配置项增加'文件空间绑定域名',
    'upload_type'=>'upyun',//或local
    'upyun'=>array(
        'bucket'=>'空间名',
        'username'=>'用户名',
        'password'=>'密码',
        'host'=>'v0.api.upyun.com'
        ),
    );
