二維碼生成方法採用phpqrcode插件 ,採用命名空間設計在extend建立phpqrcode文件夾,下面在建立QRcode.php
代碼太長附下載鏈接
下載鏈接
use phpqrcode\QRcode;
//生成二維碼圖片返回鏈接地址
public function qrcode(){
$recommend = "10003";
$url = config('WEB_URL')."?recommend=".$recommend;
$path = "./public/qrcode/".$recommend.".jpg";
if(!file_exists('./public/qrcode/')){
mkdir('./public/qrcode/',0777,true);
}
$level=3;
$size=5;
$errorCorrectionLevel =intval($level);
$matrixPointSize = intval($size);
QRcode::png($url, $path, $errorCorrectionLevel, $matrixPointSize, 2);
$host = config('WEB_URL');
$r_path = "/public/qrcode/".$recommend.".jpg";
$img = $host.'/'.$r_path;
return $img;
