php解析识别二维码内容
php解析识别⼆维码内容
使⽤框架ThinkPHP5
我在⽹上了⼀些⽅法，⽐较具有参考意义的帖⼦如下：
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：
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：

2.打开vendor/composer/autoload_files.php，添加如下代码：
<?php
/

$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
