1.创建一个CodeImgController控制器
namespace App\Http\Controllers;
use Illuminate\Foundation\Bus\DispatchesJobs;

use Illuminate\Foundation\Validation\ValidatesRequests;
use Illuminate\Foundation\Auth\Access\AuthorizesRequests;
use SimpleSoftwareIO\QrCode\Facades\QrCode;
use DB;
class CodeImgController extends BaseController
{
private $date,$img,$main,$width,$height,$target,$white;
public function constr($source,$save_path)
{
$this->date = '' . date('Ymd') . '/';
$this->img = $save_path ;
$this->main = imagecreatefromjpeg($source);
$this->width = imagesx($this->main);
$this->height = imagesy($this->main);
$this->target = imagecreatetruecolor($this->width, $this->height);
$this->white = imagecolorallocate($this->target, 255, 255, 255);
imagefill($this->target, 0, 0, $this->white);
imagecopyresampled($this->target, $this->main, 0, 0, 0, 0, $this->width, $this->height, $this->width, $this->height);
}

}
}

public function generateImg($source,$save_path, $codeurl, $sourcewidth, $sourceheight, $codewidth = 100, $codeheight = 100)
{

2.使用
$PictureContent = $https.$_SERVER['SERVER_NAME'].'/api/v1/user/code/register/html/'.session('ru_id');
$PictureFormat = 'png';
$PictureUrl = '/images/SalesmanCode/'.session('ru_id')."_".$time.".".$PictureFormat;
// $img_url = $PBULIC->SalesmanCode($PictureContent,$PictureUrl,$PictureFormat);
//背景图片
$source = public_path()."/img/bg_qcode.jpg";
$save_path = $PictureUrl;
$codeImg = new CodeImgController($source,$save_path);
$codeurl = public_path().$save_path;
$codeImg->qrencode($PictureContent,$PictureUrl,$PictureFormat);
$generateImg = $codeImg->generateImg($source,$save_path, $codeurl, $sourcewidth = 290, $sourceheight= 390, $codewidth = 500, $codeheight = 500);
$text = $seller_info->shop_name;
$font = public_path().'/font/fangsong_GB2312.ttf';
$img_url = $codeImg->generateFont($codeurl,$save_path, $text, $textwidth=310, $textherght=1150,$fontSize = 40, $cate1 = 255, $cate2 = 255, $cate3 = 250,$font);
$salesman_code = $https.$_SERVER['SERVER_NAME'].$img_url;
