说明：这篇文章主要为大家详细介绍了Thinkphp3.2.3整合phpqrcode生成带二维码的实现方法并提供图像下载，感兴趣的小伙伴们可以参考一下
缘由：Thinkphp中没有二维码相关的库，因此我们可以通过整合phpqrcode来完成生成二维码的功能。
一、phpqrcode下载地址：http://phpqrcode.sourceforge.net/
放置位置：Thinkphp/Vendor/目录下，如下图
二、写代码
HTML代码

namespace Test\Controller;
use Think\Controller;
class EwmController extends Controller {
public function index(){
if(IS_AJAX){
//接收url
$url = I(‘get.url‘);
$UrlInfo = $this->qrcode($url);
if($UrlInfo){
$data[‘info‘] = "生成成功";
$data[‘status‘] = 1;
$data[‘url‘] = $UrlInfo;
}else{

$data[‘status‘] = 0;
}
$this->ajaxReturn($data);
}else{
$this->display();
}
}
public function qrcode($url){
ob_clean();
Vendor(‘phpqrcode.phpqrcode‘);
$level = 3;
$size = 4;
$errorCorrectionLevel = intval($level) ;//容错级别
$matrixPointSize = intval($size);//生成图片大小
//保存位置
$path = "Public/qrcode/";
// 生成的文件名
$fileName = $path.date(‘YmdHis‘,time()).‘.png‘;
//生成二维码图片
$object = new \QRcode();
$object->png($url, $fileName, $errorCorrectionLevel, $matrixPointSize, 2);
return $fileName;
}
}
三、完美结束，如果需要生成带logo的二维码，请参照文章“Thinkphp3.2版本结合phpqrcode生成带logo的二维码并提供下载”
