php解析识别二维码内容
使用框架ThinkPHP5
我在网上找了一些方法，比较具有参考意义的帖子如下：http://gitlab.szwhg.chaoxing.com/chaoxing/dingxiwhg/tree/master/vendor/khanamiryan/qrcode-detector-decoder
这种方法是使用composer来安装的，我简单说一下流程：
使用composer命令
composer require khanamiryan/qrcode-detector-decoder
安装好之后使用方法如下：
require __DIR__ . "/vendor/autoload.php"; $qrcode = new QrReader('图片地址'); $text = $qrcode->text(); //返回二维码的内容
但是，我用的时候，composer镜像地址被墙，无法下载，只能自己把这个类库下载下来，然后使用，下面就是相关经验：
首先将khanamiryan/qrcode-detector-decoder这个文件下载下来放到项目的vendor目录里面，下载链接：http://gitlab.szwhg.chaoxing.com/chaoxing/dingxiwhg/tree/master/vendor/khanamiryan/qrcode-detector-decoder
如下图：
因为我们是手动复制扩展类库过去的，所以需要在vendor加一些代码，如下：
1.打开vendor/composer/autoload_classmap.php，添加如下代码：
<?php // autoload_classmap.php @generated by Composer $vendorDir = dirname(dirname(__FILE__)); $baseDir = dirname($vendorDir); return array( 'QrReader' => $vendorDir .

2.打开vendor/composer/autoload_files.php，添加如下代码：
<?php // autoload_files.php @generated by Composer $vendorDir = dirname(dirname(__FILE__)); $baseDir = dirname($vendorDir); return array( '626dcc41390ebdaa619faa02d99943b0' => $vendorDir . '/khanamiryan/qrcode-detector-decoder/lib/common/customFunctions.php', );
3.打开vendor/composer/autoload_static.php，添加如下代码：
<?php // autoload_static.php @generated by Composer namespace Composer\Autoload; class ComposerStaticInit03c3364a4f1922a40ddcc934d3140c97 { public static $files = array ( '626dcc41390ebdaa619faa02d99943b0' => __DIR__ .

'/..' . '/khanamiryan/qrcode-detector-decoder/lib/ResultPoint.php', ); }
至此，大功告成，调用方法如下：
<?php
namespace app\index\controller;
use think\Controller;
class Index
{
fuction test(){
require ROOT_PATH."/vendor/autoload.php";
$qrcode = new \QrReader('N:\phpStudy\WWW\qukuaigou\public\tgcode\1.png');
echo $qrcode->text();
}
}
