Uploader模块管理网络上传任务，用于从本地上传各种文件到服务器，并支持跨域访问操作。通过plus.uploader可获取上传管理对象。Uploader上传使用HTTP的POST方式提交数据，数据格式符合Multipart/form-data规范，即rfc1867（Form-based File Upload in HTML）协议。

以下是TP的代码
public function upfile(){
if(@$_FILES["testdoc"]["error"] === 0){
$file = request()->file('testdoc');
$info = $file->rule('uniqid')->move(ROOT_PATH.'public'.DS.'uploads'.DS.'wechatpay');
echo $info->getFilename();
}else{
echo '上传失败';
}
$this->addlogs(date('Y-m-d H:i:s'));
}
