二，编写php代码

controller/Index.php

<?php
namespace app\controller;
 
use app\BaseController;
use app\result\Result;
use Mpdf\Mpdf;
 
class Index extends BaseController
{
    //创建pdf文件
    public function makePdf() {
        $id=123;
        //用html形式生成pdf
        $html_content = '<p style="text-align: center;">
         <span style="color: rgb(153, 0, 0); font-size: 15px; text-align: center;">
             <img src="https://imgs-qn.iliangcang.com/ware/slider/1775.jpg" title="191335ODA5NzgyNzMwMzAy.jpg" alt="QQ截图20200306180410.jpg"/>
             </span>
    </p>
    <p style="text-align: center;">
        <span style="color: rgb(153, 0, 0); font-size: 15px; text-align: center;">
        一年一度春节伴手礼大赛，带什么全家最开心?
        </span>
    </p>
    <p style="text-align: center;">
        <img src="http://img.baidu.com/hi/jx2/j_0034.gif"/>
        <img src="http://img.baidu.com/hi/jx2/j_0040.gif"/>
    </p>';
 
        //tempDir指定临时文件目录，需要有可写入的权限，否则会报错
        $mpdf = new Mpdf(['mode'=>'utf-8',
            'format' => 'A4',
            'tempDir' => '/var/www/html/tmp'
        ]);
        $mpdf->SetDisplayMode('fullpage');
        //自动分析录入内容字体
        $mpdf->autoScriptToLang = true;
        $mpdf->autoLangToFont = true;
        //文章pdf文件存储路径
        $fileUrl = "/var/www/html/pdf/article_".$id.".pdf";
        //以html为标准分析写入内容
        $mpdf->WriteHTML($html_content);
        //生成文件
        $mpdf->Output($fileUrl);
        //判断是否生成文件成功
        if (is_file($fileUrl)){
            return Result::Success("文件生成成功");
        } else {
            return Result::Error(1,"文件生成失败");
        }
    }
 
    //下载pdf文件
    public function downPdf() {
        $id=123;
        $fileUrl = "/var/www/html/pdf/article_".$id.".pdf";
        return download($fileUrl,"article_".$id.".pdf");
    }
}

三，测试效果

1,生成pdf:

查看内容:

2,下载pdf

http://192.168.219.6:8000/index/downpdf

访问后文件会下载到本地

四，查看php和thinkphp的版本:

php:

thinkphp:

liuhongdi@lhdpc:/var/www/html$ cd /data/php/admapi/
liuhongdi@lhdpc:/data/php/admapi$ php think version
