库存盘点打印功能生成PDF速度太慢使用页面缓存

一.业务需求

二.产品设计

三.UI设计

四.程序设计

1.使用behavior配置页面缓存

class WmsCheckController extends Controller
{
    /**
     * @inheritdoc
     */
    public function behaviors()
    {
        return [
            'verbs' => [
                'class' => VerbFilter::className(),
                'actions' => [
                    'delete' => ['POST'],
                ],
            ],
            [
                'class' => 'yii\filters\PageCache',
                'only' => ['view'],
                'duration' => 3600,
                'variations' => [
                    \Yii::$app->language,
                ],
                'dependency' => [
                    'class' => 'yii\caching\DbDependency',
                ],
            ],
        ];
    }

　　

2.在控制器中编写redis缓存对数据进行缓存

public function actionPrint($id)
    {
        //设置无布局
        $this->layout = false;

        //获取打印数据
        $model = $this->findModel($id);

        if(!($model->is_del == 0)){
            throw new ForbiddenHttpException("该单据无法打印");
        }

        $serializedDataProvider = \Yii::$app->redis->get('wms_check_detail_data_provider');
        if (false == $serializedDataProvider){
            $wmsCheckDetail = new \backend\models\WmsCheckDetailSearch();
            $dataProvider = $wmsCheckDetail->searchByCheckId($id);
            \Yii::$app->redis->set('wms_check_detail_data_provider', serialize($dataProvider));
            \Yii::$app->redis->expire('wms_check_detail_data_provider', 3600);
        }else{
            $dataProvider = unserialize($serializedDataProvider);
        }

        //生成页面内容
        $content = $this->render('print', [
            'model' => $model,
            'dataProvider'=>$dataProvider,
        ]);
        //打印对象
//        $pdf = new \TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT,true, 'UTF-8', false);
        $pdf = (new \TCPDF('L', 'mm', array(240, 140), true, 'UTF-8', false));
        //设置无打印头
        $pdf->setPrintHeader(false);
        $pdf->setPrintFooter(false);
        //设置PDF打印纸张的编剧
        $pdf->SetMargins(20, 20,20);
        //设置单元格内边距
        $pdf->setCellPaddings(0, 0, 0, 0);
        //设置自动进入下一页
//        $pdf->SetAutoPageBreak(TRUE, PDF_MARGIN_TOP);
//        $pdf->SetAutoPageBreak(TRUE, PDF_MARGIN_BOTTOM);
//        $pdf->SetAutoPageBreak(TRUE, PDF_MARGIN_LEFT);
        $pdf->SetAutoPageBreak(TRUE, PDF_MARGIN_RIGHT);
//        $pdf->SetAutoPageBreak(TRUE, 0);
        $pdf->AddPage();
        //设置字体
        $pdf->SetFont('stsongstdlight', '', 10);
        $pdf->writeHTML($content, true, false, true, false, '');
        $pdf->lastPage();
        $pdf->get('库存盘点.pdf');
    }

　　

3.进行页面缓存

<?php if ($this->beginCache($model->id, [
        'duration' => 3600,
        'enabled' => Yii::$app->request->isGet])): ?>
    <?php foreach ($dataProvider->getModels() as $detail): ?>
    <table class="table-bordered" style="font-size: 10px; border-top: 2px solid black;">
        <tr>
            <td colspan="2" class="active" align="center">名称</td>
            <td colspan="4" class="active" align="center">等级</td>
            <td colspan="4" class="active" align="center">单号</td>
