用途:

• 获取创作者主页的「合集」列表。每个合集的 topic_id 可传 fetch_collection_videos 取该合集内的视频。
• 价格：0.01$/次
• ⏱️ 由于微信服务器原因，本接口响应较慢，请将客户端请求超时（timeout）设置为 30 秒；timeout 设置过小会造成已扣费但收不到响应的情况。
• ⚠️ 大整数 ID 精度：响应中的 topic_id 等为 64 位大整数，超出 JavaScript 安全整数范围（2^53-1）。请始终以字符串方式接收 / 传递这类 ID（解析 JSON 用 json-bigint 或按文本取值），勿让其经过 JS Number。Swagger UI 文档页对超大整数会末位舍入显示，属正常现象，不影响接口实际返回的数据。

参数:

• username: 视频号 finder username（v2_…@finder 格式）。示例 v2_060000231003b20faec8c6e4811dc1d4c602ee30b0771bbcf220c67926bb76ab7702ac335a53@finder（人民日报）。
• raw: 可选，默认 True。True=原始响应；False=精简解析结构。

返回:

• 合集列表

响应结构与 JSON Path:

raw=false（精简，snake_case）:

• $.data.username —— finder username
• $.data.count —— 合集总数（示例 6）
• $.data.collections[] —— 合集数组，逐个（N 为下标）:
  • $.data.collections[N].topic_id —— 合集 ID（纯数字，传 fetch_collection_videos，示例 14616794565351966924）
  • $.data.collections[N].name —— 合集名（如「早安中国」）
  • $.data.collections[N].desc —— 合集简介（可能为空串）
  • $.data.collections[N].cover_url —— 合集封面
  • $.data.collections[N].feed_count —— 合集内视频数
  • $.data.collections[N].topic_type —— 合集类型（示例 16，与 fetch_collection_videos 的 topic_type 对应）

raw=true（完整原始响应，camelCase）:

• $.data.collectionCount → count
• $.data.collectionInfo[] → collections[]，逐个:
  • $.data.collectionInfo[N].collectionTopicId → topic_id（数字；另有 collectionTopicIdStr 字符串别名）
  • $.data.collectionInfo[N].collectionName → name
  • $.data.collectionInfo[N].collectionDesc → desc
  • $.data.collectionInfo[N].coverImgUrl → cover_url
  • $.data.collectionInfo[N].feedCount → feed_count
  • $.data.collectionInfo[N].collectionTopicType → topic_type
  • 另含 lastUpdateTime / readCount / categoryId 等原始字段
• $.data.lastBuffer —— 合集列表翻页游标（通常为空，合集数少不需翻页）

Purpose:

• Get the "Collections" list on a creator's homepage. Pass each collection's topic_id to fetch_collection_videos to get its videos.
• Price: $0.01 per request
• ⏱️ Due to WeChat server latency, this endpoint responds slowly; please set your client request timeout to 30 seconds — a timeout that is too small may result in being billed without receiving the response.
• ⚠️ Large-integer ID precision: IDs such as topic_id in the response are 64-bit big integers beyond JavaScript's safe-integer range (2^53-1). Always receive / pass such IDs as strings (parse JSON with json-bigint or read them as text), never through JS Number. Swagger UI rounds the trailing digits of huge integers in its docs view — this is expected and does not affect the actual data returned by the API.

Parameters:

• username: WeChat Channels finder username (v2_…@finder format). E.g. v2_060000231003b20faec8c6e4811dc1d4c602ee30b0771bbcf220c67926bb76ab7702ac335a53@finder (People's Daily).
• raw: Optional, default True. True=raw response; False=simplified parsed structure.

Return:

• Collection list

Response structure & JSON Path:

raw=false (simplified, snake_case):

• $.data.username — finder username
• $.data.count — total collections (e.g. 6)
• $.data.collections[] — collection array, per item (N is the index):
  • $.data.collections[N].topic_id — collection ID (numeric, pass to fetch_collection_videos, e.g. 14616794565351966924)
  • $.data.collections[N].name — collection name (e.g. "早安中国")
  • $.data.collections[N].desc — collection description (may be empty string)
  • $.data.collections[N].cover_url — collection cover
  • $.data.collections[N].feed_count — number of videos in the collection
  • $.data.collections[N].topic_type — collection type (e.g. 16, matches topic_type of fetch_collection_videos)

raw=true (full raw response, camelCase):

• $.data.collectionCount → count
• $.data.collectionInfo[] → collections[], per item:
  • $.data.collectionInfo[N].collectionTopicId → topic_id (number; collectionTopicIdStr provides a string alias)
  • $.data.collectionInfo[N].collectionName → name
  • $.data.collectionInfo[N].collectionDesc → desc
  • $.data.collectionInfo[N].coverImgUrl → cover_url
  • $.data.collectionInfo[N].feedCount → feed_count
  • $.data.collectionInfo[N].collectionTopicType → topic_type
  • Also raw fields like lastUpdateTime / readCount / categoryId
• $.data.lastBuffer — pagination cursor of the collection list (usually empty; few collections, no pagination needed)
