`PUT /api/v1/carts/{account}/lines` — 需要 token · cart:write · 写操作 · 2 点

购物车

## 路径参数

| 名称 | 类型 | 说明 |
| --- | --- | --- |
| `account` **必填** | string | 购物车所属账号（OMS 网站的登录账号，如 100470admin）。 (最长 64) |

## 请求体（JSON）

| 字段 | 类型 | 说明 |
| --- | --- | --- |
| `lines` **必填** | array<object> | 明细数组，每项 { sku, quantity }。至少一项；quantity=0 在调整锁单 / 购物车时表示去掉这一行。 (1–500) |
| `lines[].sku` **必填** | string | SKU / 条码——**具体到颜色和尺码**的那一层，如 OB0021611。查整个款请改用 product_code。 (最长 64) |
| `lines[].quantity` **必填** | integer | 件数，正整数，如 2。锁单调整 / 购物车里传 0 表示去掉这一行。 (0–99999) |

## 响应

响应信封只看 HTTP 状态码：成功是 2xx，正文 `{ data: … }`（列表另带 `page / page_size / has_more` 或 `total_count`）；失败是 4xx / 5xx，正文 `{ error: { code, message, hint, request_id, doc_url } }`。

```json
{
  "data": { … }
}
```

成功响应里没有任何给人看的文字——没有 `code / result / msg`。`error.code` 是唯一该用程序判断的字段，`message` 跟随 `Accept-Language`。

> 写操作请带 `Idempotency-Key` 头（任意唯一串，如 UUID）：网络重试不会重复下单。下单默认只建草稿，由人在 ERP 确认后生效。
