PHP教程2. 使用方法：

代碼如下:
//授權接口哀求參數
$sum = 0.01; //測試用金額
$req_data = '<direct_trade_create_req><subject>充值</subject>';
$req_data .= '<out_trade_no>'.$orderNo.'</out_trade_no>';
$req_data .= '<total_fee>'.$sum.'</total_fee>';
$req_data .= '<call_back_url>'.Url::toRoute(['payment/return'], true).'</call_back_url>';
$req_data .= '<notify_url>'.Url::toRoute(['payment/notify'], true).'</notify_url>';
$req_data .= '<seller_account_name>'.Yii::$app->params['alipay']['seller_email'].'</seller_account_name>';
$req_data .= '</direct_trade_create_req>';
$params = [
??? 'service' => 'alipay.wap.trade.create.direct',
??? 'format' => 'xml',
??? 'v' => '2.0',
??? 'partner' => Yii::$app->params['alipay']['partner'], //合作者省份ID
??? 'req_id' => date('Ymdhis'),
??? 'sec_id' => Yii::$app->params['alipay']['sign_type'],
??? 'req_data' => $req_data,
];
?
$alipay = new Alipay();
$alipay->key = Yii::$app->params['alipay']['key'];
$alipay->alipay_config = $params;
$url = $alipay->buildPageUrl();
$this->redirect($url);

3. 配置示例：
代碼如下:
//支付寶相關配置
'alipay' => [
??????? 'key' => 'XXXXX',? //交易安全校驗碼,用于簽名的32位密鑰
??????? 'transport' => 'https',???????? //消息驗證地址使用訪問方式
??????? 'seller_email' => 'XXXX', //賣家支付寶賬號,即收款賬戶
??????? 'service' => 'create_direct_pay_by_user', //接口名稱
??????? 'partner' => 'XXXX', //合作者省份ID
??????? '_input_charset' => 'utf-8', //參數編碼字符集
??????? 'sign_type' => 'MD5', //簽名方式,不參加簽名,目前只能是MD5
??????? //以下兩個參數沒用
??????? 'notify_url' => '', //服務器異步通知頁面路徑
??????? 'return_url' => '', //頁面跳轉通知頁面路徑
],
