+# 皮肤源头开放接口对接文档
+
+版本：`v1`  
+Base URL：`https://{你们的域名}`（开发环境示例：`http://localhost:8080`）  
+统一响应：
+
+```json
+{
+  "code": 0,
+  "message": "ok",
+  "data": {}
+}
+```
+
+- `code = 0` 表示成功
+- `code != 0` 表示失败，以 `message` 为准
+
+---
+
+## 1. 鉴权（ApiKey + 签名）
+
+开放接口采用 **双因子**：
+
+| 凭证 | 说明 |
+|------|------|
+| `api_key` | 标识对接方，放在请求头 `X-Api-Key` |
+| `api_secret` | **仅用于本地算签名，禁止放在 Header / 前端 / 日志明文传输** |
+
+每次请求必须带齐：
+
+| Header | 必填 | 说明 |
+|--------|------|------|
+| `X-Api-Key` | 是 | 对接方 Key |
+| `X-Timestamp` | 是 | Unix **秒**级时间戳 |
+| `X-Nonce` | 是 | 随机串，长度 8~64，同一 Key 下有效期内不可重复 |
+| `X-Sign` | 是 | HMAC-SHA256 签名，小写十六进制 |
+
+### 1.1 签名算法
+
+待签名字符串（UTF-8，行之间用 `\n`，共 6 行）：
+
+```text
+{api_key}
+{timestamp}
+{nonce}
+{METHOD}
+{path}
+{body}
+```
+
+| 项 | 规则 |
+|----|------|
+| METHOD | 大写，如 `GET` / `POST` |
+| path | `URL.Path`，**不含** query，如 `/api/open/v1/orders/O123` |
+| body | 原始请求体字符串；GET 无 body 时用 **空字符串**（仍保留最后一行空内容，即末尾仍有换行结构中的 body 段为空） |
+
+计算：
+
+```text
+X-Sign = hex( HMAC-SHA256( api_secret, string_to_sign ) )
+```
+
+- 使用 **小写** hex  
+- 时间戳与服务器偏差超过 **300 秒**（可配置）则拒绝  
+- 同一 `api_key + nonce` 在有效期内重复使用 → 拒绝（防重放）
+
+### 1.2 Python 示例
+
+```python
+import hmac, hashlib, time, uuid, requests
+
+API_KEY = "sk_source_dev_key_change_me"
+API_SECRET = "sk_source_dev_secret_change_me"
+BASE = "http://localhost:8080"
+
+def sign(method: str, path: str, body: str = "") -> dict:
+    ts = str(int(time.time()))
+    nonce = uuid.uuid4().hex
+    string_to_sign = "\n".join([API_KEY, ts, nonce, method.upper(), path, body])
+    sign_hex = hmac.new(
+        API_SECRET.encode(), string_to_sign.encode(), hashlib.sha256
+    ).hexdigest()
+    return {
+        "X-Api-Key": API_KEY,
+        "X-Timestamp": ts,
+        "X-Nonce": nonce,
+        "X-Sign": sign_hex,
+    }
+
+# 查询订单
+path = "/api/open/v1/orders/O202607201550038000"
+r = requests.get(BASE + path, headers=sign("GET", path))
+print(r.json())
+
+# 发货推送
+path = "/api/open/v1/orders/ship-notify"
+body = '{"order_no":"O202607201550038000","ship_status":"success","provider_order_no":"SRC001"}'
+headers = {"Content-Type": "application/json", **sign("POST", path, body)}
+r = requests.post(BASE + path, headers=headers, data=body.encode())
+print(r.json())
+```
+
+> **注意**：POST 签名用的 `body` 必须与实际发送的 body **字节级一致**（不要先 `json.dumps` 又改空格）。
+
+### 1.3 鉴权失败示例
+
+```json
+{ "code": 401, "message": "签名校验失败" }
+```
+
+常见原因：secret 错误、body 不一致、timestamp 过期、nonce 重复、path 写错（多了 query / 域名）。
+
+### 1.4 环境变量（我方）
+
+| 变量 | 说明 | 开发默认 |
+|------|------|----------|
+| `OPEN_API_KEY` | Api Key | `sk_source_dev_key_change_me` |
+| `OPEN_API_SECRET` | 签名密钥 | `sk_source_dev_secret_change_me` |
+| `OPEN_SIGN_SKEW` | 时间偏差秒数 | `300` |
+
+生产务必更换 Key / Secret。
+---
+
+## 2. 对接流程
+
+```text
+1. 买家在店铺下单并完成支付
+2. 上游拿到「店铺订单号 order_no」
+3. 调用【订单查询】确认商品 sku、can_ship
+4. can_ship=true 时执行发货
+5. 发货结果调用【发货推送】回传
+6. 我方同步订单状态；重复推送 success 幂等成功
+```
+
+---
+
+## 3. 订单查询（发货前置）
+
+### 请求
+
+```http
+GET /api/open/v1/orders/{order_no}
+X-Api-Key: {api_key}
+X-Timestamp: {unix_seconds}
+X-Nonce: {random_8_to_64}
+X-Sign: {hmac_sha256_hex}
+```
+
+### 成功响应
+
+```json
+{
+  "code": 0,
+  "message": "ok",
+  "data": {
+    "order_no": "O202607201550038000",
+    "status": "paid",
+    "can_ship": true,

+    "shipped_at": null,
+    "ship_fail_reason": ""
+  }
+}
+```
+
+### 字段说明
+
+| 字段 | 类型 | 说明 |
+|------|------|------|
+| order_no | string | 店铺订单号 |
+| status | string | 订单状态，见下表 |
+| can_ship | bool | **是否允许发货**，请以此为准 |
+| cannot_ship_reason | string | 不可发货原因（can_ship=false 时） |
+| product.name | string | 商品中文名 |
+| product.sku | string | **商品英文固定标识，发货请用此字段** |
+| product.game | string | 游戏，如「和平精英」 |
+| buyer_name | string | 买家备注名 |
+| amount | number | 订单金额 |
+| provider_order_no | string | 上游单号（若已回传） |
+| created_at | string | 下单时间 |
+| shipped_at | string\|null | 发货成功时间 |
+| ship_fail_reason | string | 最近一次发货失败原因 |
+
+### 订单状态 status
+
+| 值 | 含义 | can_ship |
+|----|------|----------|
+| pending | 待支付 | false |
+| paid | 已支付 | **true** |
+| delivering | 发货中 | false |
+| delivered | 已交付 | false |
+| ship_failed | 发货失败（可重试） | **true** |
+| cancelled | 已取消 | false |
+
+### 错误
+
+| HTTP | message |
+|------|---------|
+| 401 | 鉴权失败（Key / 签名 / 时间 / Nonce） |
+| 404 | 订单不存在 |
+| 400 | 订单号不能为空 |
+
+### 调用说明
+
+请使用上一节 Python 示例生成签名后请求；仅带 `X-Api-Key` 而不带签名会被拒绝。
+
+---
+
+## 4. 发货结果推送
+
+### 请求
+
+```http
+POST /api/open/v1/orders/ship-notify
+Content-Type: application/json
+X-Api-Key: {api_key}
+X-Timestamp: {unix_seconds}
+X-Nonce: {random_8_to_64}
+X-Sign: {hmac_sha256_hex}
+```
+
+```json
+{
+  "order_no": "O202607201550038000",
+  "ship_status": "success",
+  "provider_order_no": "SRC20260720001",
+  "shipped_at": "2026-07-20T16:00:00+08:00",
+  "fail_reason": ""
+}
+```
+
+### 请求字段
+
+| 字段 | 必填 | 说明 |
+|------|------|------|
+| order_no | 是 | 店铺订单号 |
+| ship_status | 是 | `success` / `failed` / `processing` |
+| provider_order_no | 否 | 上游发货单号 |
+| shipped_at | 否 | 发货时间，RFC3339；success 时缺省用服务端时间 |
+| fail_reason | 否 | 失败原因（failed 时建议填写） |
+
+### ship_status 与订单状态映射
+
+| ship_status | 订单变为 | 说明 |
+|-------------|---------|------|
+| processing | delivering | 已接单/发货中 |
+| success | delivered | 发货成功 |
+| failed | ship_failed | 发货失败，允许再次查询后重试 |
+
+### 幂等
+
+- 订单已是 `delivered`，再次推送 `success` → **返回成功**，不重复处理
+- 订单已是 `delivered`，推送 `failed` → 拒绝
+- 订单 `cancelled` → 拒绝更新
+
+### 成功响应
+
+```json
+{
+  "code": 0,
+  "message": "ok",
+  "data": {
+    "order_no": "O202607201550038000",
+    "status": "delivered",
+    "message": "发货成功，订单已交付"
+  }
+}
+```
+
+### 调用说明
+
+Body 与签名字符串中的 body **必须完全一致**。完整示例见 **§1.2 Python**。
+
+| ship_status | body 示例 |
+|-------------|-----------|
+| processing | `{"order_no":"O...","ship_status":"processing","provider_order_no":"SRC..."}` |
+| success | `{"order_no":"O...","ship_status":"success","provider_order_no":"SRC...","shipped_at":"2026-07-20T16:00:00+08:00"}` |
+| failed | `{"order_no":"O...","ship_status":"failed","fail_reason":"账号不存在"}` |
+
+---
+
+## 5. 推荐调用顺序
+
+```text
+query → can_ship?
+  ├─ false → 停止，展示 cannot_ship_reason
+  └─ true
+       →（可选）push processing
+       → 执行发货
+       → push success / failed
+```
+
+发货务必使用查询结果中的 **`product.sku`**，不要仅依赖中文名。
+
+---
+
+## 6. 联调检查清单
+
+- [ ] 缺少 Sign / 错误 Secret 返回 401  
+- [ ] 错误 ApiKey 返回 401  
+- [ ] 过期 Timestamp / 重复 Nonce 返回 401  
+- [ ] 不存在的订单号返回 404  
+- [ ] `pending` 订单 `can_ship=false`  
+- [ ] `paid` 订单 `can_ship=true` 且 sku 正确  
+- [ ] success 推送后状态为 delivered  
+- [ ] 重复 success 幂等成功  
+- [ ] failed 后可再次 query 且 can_ship=true
