获取视频号合集内视频/Get WeChat Channels Collection Videos

[中文]

用途:

  • 给定合集 topic_id(来自 fetch_user_collections),返回该合集内的视频列表。
  • 每个视频带媒体地址 media(含 url / url_token / decode_key),可直接下载解密。
  • 支持翻页获取更多视频。
  • 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 id / 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:

  • topic_id: 合集 ID(纯数字,来自 fetch_user_collectionstopic_id)。示例 14616794565351966924(人民日报「早安中国」合集)。
  • topic: 可选,合集名,提高命中。示例 早安中国
  • username: 可选,创作者 finder username(v2_…@finder 格式),提高命中。
  • last_buffer: 可选,翻页游标(base64),首页留空;当响应 down_continue 为真时,传上一页响应的 last_buffer 取下一页。
  • topic_type: 可选,合集类型,默认 16(与 fetch_user_collections 里该合集的 topic_type 对齐)。
  • raw: 可选,默认 True。True=原始响应;False=精简解析结构(推荐做媒体下载)。

返回:

  • 合集内视频列表及翻页游标

响应结构与 JSON Path:

raw=false(精简,snake_case,推荐做媒体下载):

  • $.data.topic_id / $.data.title(合集名)
  • $.data.total_count —— 合集总视频数;$.data.count —— 本页条数(示例 20)
  • $.data.videos[] —— 视频数组,逐个(N 为下标):
    • $.data.videos[N].id —— 作品 objectId(可喂 fetch_video_detail / fetch_video_comments
    • $.data.videos[N].username / .nickname / .title(可能为 null)/ .create_time
    • $.data.videos[N].read_count / .like_count / .fav_count / .forward_count / .comment_count
    • $.data.videos[N].media —— 媒体对象(单个),下载 + 解密:
      • $.data.videos[N].media.url —— 视频 CDN 链接(不带 Token)
      • $.data.videos[N].media.url_token —— CDN 链接 Token(防盗链)
      • $.data.videos[N].media.full_url —— 已拼好的完整 CDN URL(= url + url_token,可直接下载)
      • $.data.videos[N].media.decode_key —— 视频解密密钥(每次请求都不同
      • 另含 cover_url / duration / width / height / media_type
  • $.data.down_continue —— 是否有下一页(1=有)
  • $.data.last_buffer —— 翻页游标(传回本接口取下一页)

raw=true(完整原始响应,camelCase):

  • $.data.totalCounttotal_count
  • $.data.object[]videos[](完整视频对象),逐个:
    • $.data.object[N].idid$.data.object[N].usernameusername
    • 媒体在 $.data.object[N].objectDesc.media[0]: .urlurl.urlTokenurl_token.decodeKeydecode_keyfull_url 为精简层拼接产物,raw 需自行 url + urlToken 拼接)
  • $.data.downContinueFlagdown_continue(注意 raw 顶层另有 continueFlag,合集翻页以 downContinueFlag 为准)
  • $.data.lastBuffer(别名 $.data.last_buffer)→ last_buffer

重要提示(视频下载与解密):

[English]

Purpose:

  • Given a collection topic_id (from fetch_user_collections), return the video list inside that collection.
  • Each video carries a media object (url / url_token / decode_key) ready for download and decryption.
  • Supports pagination for more 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 id / 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:

  • topic_id: Collection ID (numeric, from topic_id of fetch_user_collections). E.g. 14616794565351966924 (People's Daily "早安中国" collection).
  • topic: Optional, collection name, improves hit rate. E.g. 早安中国.
  • username: Optional, creator finder username (v2_…@finder format), improves hit rate.
  • last_buffer: Optional pagination cursor (base64), leave empty for the first page; when down_continue is truthy, pass the previous page's last_buffer.
  • topic_type: Optional, collection type, default 16 (align with the collection's topic_type from fetch_user_collections).
  • raw: Optional, default True. True=raw response; False=simplified parsed structure (recommended for media download).

Return:

  • Video list of the collection with pagination cursor

Response structure & JSON Path:

raw=false (simplified, snake_case, recommended for media download):

  • $.data.topic_id / $.data.title (collection name)
  • $.data.total_count — total videos in the collection; $.data.count — items on this page (e.g. 20)
  • $.data.videos[] — video array, per item (N is the index):
    • $.data.videos[N].id — video objectId (feed into fetch_video_detail / fetch_video_comments)
    • $.data.videos[N].username / .nickname / .title (may be null) / .create_time
    • $.data.videos[N].read_count / .like_count / .fav_count / .forward_count / .comment_count
    • $.data.videos[N].media — media object (single), download + decrypt:
      • $.data.videos[N].media.url — video CDN link (without Token)
      • $.data.videos[N].media.url_token — Token of the CDN link (anti-hotlinking)
      • $.data.videos[N].media.full_url — pre-concatenated full CDN URL (= url + url_token, ready to download)
      • $.data.videos[N].media.decode_key — video decryption key (different on every request)
      • Also cover_url / duration / width / height / media_type etc.
  • $.data.down_continue — has next page (1=yes)
  • $.data.last_buffer — pagination cursor (pass back to this endpoint for the next page)

raw=true (full raw response, camelCase):

  • $.data.totalCounttotal_count
  • $.data.object[]videos[] (full video objects), per item:
    • $.data.object[N].idid; $.data.object[N].usernameusername
    • Media at $.data.object[N].objectDesc.media[0]: .urlurl, .urlTokenurl_token, .decodeKeydecode_key (full_url is produced by the simplified layer; for raw, concatenate url + urlToken yourself)
  • $.data.downContinueFlagdown_continue (note: raw top level also has continueFlag; for collection pagination use downContinueFlag)
  • $.data.lastBuffer (alias $.data.last_buffer) → last_buffer
