php解析識別二維碼內容

使用框架ThinkPHP5

我在網上找了一些方法，比較具有參考意義的帖子如下：http://gitlab.szwhg.chaoxing.com/chaoxing/dingxiwhg/tree/master/vendor/khanamiryan/qrcode-detector-decoder

這種方法是使用composer來安裝的，我簡單說一下流程：

　　使用composer命令

composer require khanamiryan/qrcode-detector-decoder

　　安裝好之后使用方法如下：

require __DIR__ . "/vendor/autoload.php";  
$qrcode = new QrReader('圖片地址');
$text = $qrcode->text(); //返回二維碼的內容

 但是，我用的時候，composer鏡像地址被牆，無法下載，只能自己把這個類庫下載下來，然后使用，下面就是相關經驗：

首先將khanamiryan/qrcode-detector-decoder這個文件下載下來放到項目的vendor目錄里面，下載鏈接：http://gitlab.szwhg.chaoxing.com/chaoxing/dingxiwhg/tree/master/vendor/khanamiryan/qrcode-detector-decoder

如下圖：

 

 因為我們是手動復制擴展類庫過去的，所以需要在vendor加一些代碼，如下：

1.打開vendor/composer/autoload_classmap.php，添加如下代碼：

<?php

// autoload_classmap.php @generated by Composer

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

return array(

);

 2.打開vendor/composer/autoload_files.php，添加如下代碼：

<?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.打開vendor/composer/autoload_static.php，添加如下代碼：

<?php

// autoload_static.php @generated by Composer

namespace Composer\Autoload;

class ComposerStaticInit03c3364a4f1922a40ddcc934d3140c97

    );

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

 

至此，大功告成，調用方法如下：

<?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();
　　}
}
