//获取新单据号
public function actionInclude(){
    $model = new UploadForm();

    if (Yii::$app->request->isPost) {
        $model->file = UploadedFile::getInstance($model, 'file');

        $allow = array('xls','xlsx');
        if ($model->file && in_array($model->file->extension,$allow)) {
            $result = $model->file->saveAs('uploads/' . $model->file->baseName . '.' . $model->file->extension);
            if($result){
                echo '200';
                exit;
            }else{
                echo '上传失败';
                exit;
            }
        }else{
            echo '格式不对';
            exit;
        }
    }

    return $this->render('includeView', ['model' => $model]);
