  "documentation": "# 易支付\n\n官方 `yingce.payment/v1` 支付插件。兼容常见易支付网关：V1/MD5 `mapi.php` 与 V2/RSA `/api/pay/create`，支持支付宝/微信/QQ 等通道。协议实现参考 [acg-faka](https://github.com/lizhipay/acg-faka)。\n\n---\n\n## yingce.payment/v1\n\n支持 `validate_config`、`create_order`、`query_order`、`close_order`、`verify_notification` 和 `download_trade_bill`，统一返回 JSON 响应。\n\n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`。\n\n必须显式填写可信 `gateway`，不默认向任何第三方网关发送商户信息。V1 查单严格校验商户（响应包含时）、订单号、正数金额、支付状态和成功流水号；不以请求中的订单号或零金额掩盖不完整响应。通知校验拒绝重复参数、无效签名、非正金额及缺失的成功流水号。支付地址只接受 HTTP(S) 与明确允许的微信、支付宝、QQ 支付协议，不接受任意本机协议或含用户名密码的地址。\n\nV1 关单先查单：已支付订单返回付款凭据，未付款订单只关闭宿主本地记录，不能据此声称上游支付链接已失效。V2 当前仅实现下单和通知验签，未实现查单、刷新收银台和安全关单；`query_order` 返回 `epay_query_unsupported`，`close_order` 返回 `epay_close_unsupported`，不会把未知订单标成已关闭。启用 V2 前需接受这一限制并准备在网关人工核对订单；本次没有新增或猜测 V2 查单接口。交易账单下载返回 not found，不表示已完成对账。\n\n<!-- YINGCE_MANIFEST_CONTRACT_START -->\n## Manifest 完整接口定义\n\n以下 JSON 与插件包内实际 `manifest.json` 逐字段一致，覆盖插件身份、权限、配置、鉴权、参数、校验、创建、Agent、查询、取消、结果下载、响应和 Agent 响应映射。`documentation` 字段的值就是当前完整文档；为避免文档在自身内部无限递归，JSON 中仅用等义占位文本表示正文。\n\n```json\n{\n  \"apiVersion\": \"yingce.plugin/v1\",\n  \"id\": \"official-payment-epay\",\n  \"name\": \"易支付\",\n  \"version\": \"1.0.9\",\n  \"author\": \"Epay\",\n  \"description\": \"易支付适配器，支持 V1/MD5 与 V2/RSA 的支付宝/微信/QQ 通道。\",\n  \"enabled\": true,\n  \"installable\": true,\n  \"runtime\": {\n    \"backend\": \"rpc\",\n    \"backendEntry\": \"backend/provider\"\n  },\n  \"surfaces\": [\n    \"wallet\",\n    \"settings\"\n  ],\n  \"permissions\": [\n    \"payment.create\",\n    \"payment.query\",\n    \"payment.close\",\n    \"payment.reconcile\"\n  ],\n  \"configuration\": {\n    \"fields\": [\n      {\n        \"name\": \"publicBaseUrl\",\n        \"type\": \"url\",\n        \"label\": \"服务器公网地址\",\n        \"required\": true,\n        \"description\": \"用于确认回调可达；实际 notify_url 由宿主订单生成。\"\n      },\n      {\n        \"name\": \"pid\",\n        \"type\": \"string\",\n        \"label\": \"商户号 (pid)\",\n        \"required\": true\n      },\n      {\n        \"name\": \"key\",\n        \"type\": \"password\",\n        \"label\": \"商户密钥 (key)\",\n        \"required\": false,\n        \"secret\": true,\n        \"description\": \"V1/MD5 密钥；version=1 可留空。\"\n      },\n      {\n        \"name\": \"gateway\",\n        \"type\": \"url\",\n        \"label\": \"支付网关\",\n        \"required\": true,\n        \"description\": \"显式填写可信易支付网关根地址，不要带 /mapi.php；不会默认向第三方网关发送商户信息。\"\n      },\n      {\n        \"name\": \"payType\",\n        \"type\": \"string\",\n        \"label\": \"默认支付方式\",\n        \"required\": false,\n        \"default\": \"alipay\",\n        \"values\": [\n          \"alipay\",\n          \"wxpay\",\n          \"qqpay\",\n          \"usdt\"\n        ]\n      },\n      {\n        \"name\": \"version\",\n        \"type\": \"string\",\n        \"label\": \"接口版本\",\n        \"required\": false,\n        \"default\": \"0\",\n        \"values\": [\n          \"0\",\n          \"1\"\n        ],\n        \"description\": \"0=V1/MD5，1=V2/RSA。V2 仅支持下单和验签通知，暂不支持查单、刷新收银台及自动关单，启用前需确认此限制。\"\n      },\n      {\n        \"name\": \"checkoutMode\",\n        \"type\": \"string\",\n        \"label\": \"收银方式\",\n        \"required\": false,\n        \"default\": \"redirect\",\n        \"values\": [\n          \"redirect\",\n          \"qr_code\"\n        ],\n        \"description\": \"redirect 跳转；qr_code 展示二维码载荷。\"\n      },\n      {\n        \"name\": \"privateKey\",\n        \"type\": \"textarea\",\n        \"label\": \"V2 商户私钥\",\n        \"required\": false,\n        \"secret\": true,\n        \"description\": \"仅 version=1，PEM 或裸 Base64。\"\n      },\n      {\n        \"name\": \"platformPublicKey\",\n        \"type\": \"textarea\",\n        \"label\": \"V2 平台公钥\",\n        \"required\": false,\n        \"description\": \"仅 version=1，PEM 或裸 Base64。\"\n      }\n    ]\n  },\n  \"contributes\": {\n    \"paymentProviders\": [\n      {\n        \"id\": \"epay\",\n        \"label\": \"易支付\",\n        \"icon\": \"assets/icon.svg\",\n        \"checkoutMode\": \"redirect\",\n        \"identityFields\": [\n          \"pid\"\n        ],\n        \"expiryPolicy\": {\n          \"defaultMinutes\": 10,\n          \"minMinutes\": 5,\n          \"maxMinutes\": 1440\n        },\n        \"notificationSuccess\": {\n          \"status\": 200,\n          \"contentType\": \"text/plain;
