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(

 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__));

return array(

);

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

<?php

// autoload_static.php @generated by Composer

namespace ComposerAutoload;

class ComposerStaticInit03c3364a4f1922a40ddcc934d3140c97

        'Zxing\ResultPoint' => __DIR__ . '/..' . '/khanamiryan/qrcode-detector-decoder/lib/ResultPoint.php',
    );
}

至此，大功告成，调用方法如下：

<?php
namespace appindexcontroller;

use thinkController;

class Index
{

　　　fuction test(){　　　　

　　　　require ROOT_PATH."/vendor/autoload.php";

　　　　$qrcode = new QrReader('N:phpStudyWWWqukuaigoupublic gcode1.png');

　　　echo $qrcode->text();
　　}
}
