支付 SDK 扩展包

可能是我用过的最优雅的 Alipay 和 WeChat 的支付 SDK 扩展包了 # yansongda/pay

下面以微信为例，支付宝写法大同小异

下载地址：https://github.com/yansongda/pay

安装

composer require yansongda/pay -vvv

laravel框架

配置参数

在config目录下创建一个wechat.php微信支付配置文件

return [
    // APP APPID
    'appid' => 'wxb3fxxxxxxxxxxx', 
    //公众号 APPID
    'app_id' => 'wxb3fxxxxxxxxxxx',
    //小程序 APPID
    'miniapp_id' => 'wxb3fxxxxxxxxxxx',
    //AppSecret
    'app_secret' => 'mF2suE9sU6Mk1Cxxxxxxxxxxx',
    //小程序授权的url
    'auth_url' => "https://api.weixin.qq.com/sns/jscode2session?appid=%s&secret=%s&js_code=%s&grant_type=authorization_code",
    //商户号
    'mch_id' => '14577xxxx',
    //API密钥
    'key' => 'mF2suE9sU6Mk1Cxxxxxxxxxxx',
    //回调
    'notify_url' => 'http://xxx/payment/notify/native',
    //证书
    'cert_client' => resource_path('cert/apiclient_cert.pem'),
    'cert_key'    => resource_path('cert/apiclient_key.pem'),
    //日志
    'log' => [
        'file' => storage_path('logs/wechat_pay.log')
    ],
    //自动退款时间，30天
    'refunde_time' => 10
];

注册一个wechat_pay微信支付服务单例

app->singleton('wechat_pay', function () {
            $config = config('wechat');
            if (app()->environment() !== 'production') {
                $config['log']['level'] = Logger::DEBUG;
            } else {
                $config['log']['level'] = Logger::WARNING;
            }
            // 调用 Yansongda\Pay 来创建一个微信支付对象
            return Pay::wechat($config);
        });

    }
}

代码解析：
$this->app->singleton() 往服务容器中注入一个单例对象，第一次从容器中取对象时会调用回调函数来生成对应的对象并保存到容器中，之后再去取的时候直接将容器中的对象返回。
app()->environment() 获取当前运行的环境，线上环境会返回 production。对于支付宝，如果项目运行环境不是线上环境，则启用开发模式，并且将日志级别设置为 DEBUG。由于微信支付没有开发模式，所以仅仅将日志级别设置为 DEBUG
