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

$vendorDir = dirname(dirname(__FILE__));
$baseDir = dirname($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(

3.打开vendor/composer/autoload_static.php，添加如下代码：

}

 

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();
　　}
}
