+
+支持 `validate_config`、`create_order`、`query_order`、`close_order`、`verify_notification` 和 `download_trade_bill`，统一返回 JSON 响应。
+
+易支付渠道协议全部封装在本插件内：V1 下单 `POST /mapi.php`（MD5），查单 `GET /api.php?act=order`；V2 下单 `POST /api/pay/create`（RSA，`method=jump`），异步通知为 form/JSON，成功应答 `success`。配置字段包括 `publicBaseUrl`、`pid`、`key`、`gateway`、`payType`、`version`、`checkoutMode`、`privateKey`、`platformPublicKey`。V2 无查单和交易账单下载：关单只关本地订单，对账账单返回 not found。
