首先得下载这2个文件，不然没法用，这个配置文件是在config/snappy.php中

下载

composer require barryvdh/laravel-snappy

发布

php artisan vendor:publish --provider="Barryvdh\Snappy\ServiceProvider"

官网：https://github.com/barryvdh/laravel-snappy 需要安装字体不然是乱码；

sudo apt-get install fonts-wqy-microhei

模板输出用这个：

<?php

namespace App\Http\Controllers;

use Encore\Admin\Controllers\AdminController;
use Illuminate\Http\Request;
use Validator;
use \DB;
use PDF;
use App;
use App\Models\Xjrw;
use App\Services\SensitiveWords;

class PdfController extends Controller{

 public function index(Request $request){


$person = ["name" => "John", "age" => 30, "city" => "New York"];

// 加载 Blade 模板
        $html = view('pdf.pdf1', compact('person'))->render();

        // 生成 PDF
        $pdf = PDF::loadHTML($html);

        // 在浏览器中打开 PDF
        return $pdf->inline('task_details.pdf');
    }

}

在windwos中需要下载安,安装后,https://wkhtmltopdf.org/downloads.html 安装的目录不能带空格，配置文件如下

<?php

return [

    'pdf' => [
        'enabled' => true,
        //'binary'  => env('WKHTML_PDF_BINARY', '/usr/local/bin/wkhtmltopdf-amd64'), // linux 配置路径
        'binary'  => env('WKHTML_PDF_BINARY', 'D:\wk\wkhtmltopdf\bin\wkhtmltopdf.exe'), // windows 配置路径
        'timeout' => false,
        'options' => [],
        'env'     => [],
    ],

    'image' => [
        'enabled' => true,
        //'binary'  => env('WKHTML_IMG_BINARY', '/usr/local/bin/wkhtmltoimage-amd64'), // linux 配置路径
         'binary'  => env('WKHTML_IMG_BINARY', 'D:\wk\wkhtmltopdf\bin\wkhtmltoimage.exe'), // windows 配置路径
        'timeout' => false,
        'options' => [],
        'env'     => [],
    ],

];
