NAME
    Business::Alipay - Alipay payment

SYNOPSIS
      use Business::Alipay;

      my $alipay = Business::Alipay->new({
            "ALIPAY_KEY" => "", # 安全检验码，以数字和字母组成的32位字符
        "ALIPAY_PARTNER" => "", # 合作身份者ID，以2088开头的16位纯数字
        "ALIPAY_SELLER_EMAIL" => "", # 签约支付宝账号或卖家支付宝帐户
      });

      my $redirect_url = $alipay->create_direct_pay_by_user({
        notify_url => $notify_url, ## notify url
        return_url => $return_url, ## 返回 url

        out_trade_no => $uuid, # unique id
        subject => 'subject',
        body => 'description',
        total_fee => '0.01', # 金额
      });
      # $redirect_url is a url, you should redirect to that
      print $q->redirect($redirect_url);

      #### for return or notify, in another sub or file
      my $params = $q->params(); # or $c->req->params->to_hash for Mojolicious

      my $out_trade_no = $params->{out_trade_no};
      # make sure it's not proceeded before.
      # return if already_proceeded($out_trade_no);

      my $trade_status = $params->{trade_status};
      if ($trade_status eq 'TRADE_FINISHED' or $trade_status eq 'TRADE_SUCCESS') {
            my $r = $alipay->notify_verify($params);
            # $r is one of 'true', 'false', 'sign_dismatch', 'unknown' (unknown is HTTP failure)
      }

DESCRIPTION
    Business::Alipay is a payment gateway for <https://www.alipay.com/>.

    right now it's very incomplete and only supports
    create_direct_pay_by_user. patches are welcome.
