+## 7. 朋友圈接口
+
+### 7.1 获取朋友圈时间线
+
+```http
+GET /api/v1/sns/timeline
+```
+
+参数：
+
+| 参数 | 类型 | 必填 | 说明 |
+| --- | --- | --- | --- |
+| `limit` | number | 否 | 返回数量，默认 20，范围 `1~200` |
+| `offset` | number | 否 | 偏移量，默认 0 |
+| `usernames` | string | 否 | 发布者过滤，逗号分隔，如 `wxid_a,wxid_b` |
+| `keyword` | string | 否 | 关键词过滤（正文） |
+| `start` | string | 否 | 开始时间，支持 `YYYYMMDD` 或秒/毫秒时间戳 |
+| `end` | string | 否 | 结束时间，支持 `YYYYMMDD` 或秒/毫秒时间戳 |
+| `media` | number | 否 | 是否返回可直接访问的媒体地址，默认 `1` |
+| `replace` | number | 否 | `media=1` 时，是否用解析地址覆盖 `media.url/thumb`，默认 `1` |
+| `inline` | number | 否 | `media=1` 时，是否内联返回 `data:` URL，默认 `0` |
+
+示例：
+
+```bash
+curl "http://127.0.0.1:5031/api/v1/sns/timeline?limit=5"
+curl "http://127.0.0.1:5031/api/v1/sns/timeline?usernames=wxid_a,wxid_b&keyword=旅行"
+curl "http://127.0.0.1:5031/api/v1/sns/timeline?limit=3&media=1&replace=1"
+curl "http://127.0.0.1:5031/api/v1/sns/timeline?limit=3&media=1&inline=1"
+```
+
+媒体字段说明（`media=1`）：
+
+- `media[].url/thumb`：你应该优先直接使用的字段。
+- `replace=1`（默认）时，`media[].url/thumb` 会直接被替换成可访问地址，等价于 `resolvedUrl/resolvedThumbUrl`。
+- `replace=0` 时，`media[].url/thumb` 仍保留微信原始地址；这时再结合下面的 `raw/proxy/resolved` 字段自己决定用哪一个。
+- `media[].rawUrl/rawThumb`：原始朋友圈地址
+- `media[].proxyUrl/proxyThumbUrl`：可直接访问的代理地址
+- `media[].resolvedUrl/resolvedThumbUrl`：最终可用地址（`inline=1` 时可能是 `data:` URL）
+- `media[].token/key/encIdx`：微信源数据里的访问/解密参数。通常不需要你自己处理；如果你手动调用 `/api/v1/sns/media/proxy`，把当前条目的 `url` 和 `key` 原样传回即可。
+- `media[].livePhoto`：实况图的视频部分。外层 `media[].url/thumb` 仍是封面图，`livePhoto` 内部会再提供一组自己的 `url/thumb/raw*/proxy*/resolved*` 字段。
+- `media=0` 时，不会补充 `raw*/proxy*/resolved*`，接口只返回原始 `url/thumb` 以及源字段（如 `key/token/encIdx`）。
