昇腾社区论坛数据获取工具
用于从昇腾社区论坛 API 获取帖子数据,按时间范围筛选,自动剔除置顶贴,支持并发分页获取,并导出为 Excel 格式。
功能特性
- 灵活的时间筛选:支持"今年"、"本月"、"本周"、"今天"快捷选项,或自定义日期区间,最小粒度为天
- 智能截止时间调整:若查询截止时间超过当天,自动调整为当天23:59:59
- 置顶贴自动剔除:自动过滤 resultList 中 top > 0 的置顶贴
- 智能查询终止:当当前批次最早创建时间早于查询区间时,自动停止后续查询
- 时区自动转换:createTime 自动加8小时(北京时间转换)
- 可配置分页大小:支持自定义每页获取数据量(默认100条)
- 并发分页获取:支持多线程并发获取,提升查询效率(默认6并发)
- Excel 导出:结构化输出,包含指定字段和可点击链接
API 端点
https://www.hiascend.com/ascendgateway/ascendservice/devCenter/bbs/servlet/get-topic-list?filterCondition=1&pageIndex={page}&pageSize={pageSize}
工作流程
1. 解析并调整时间范围
将用户输入转换为开始日期和结束日期(YYYYMMDDHHMMSS 格式):
快捷选项:
今年→ 当年1月1日00:00:00 至 今天23:59:59本月→ 当月1日00:00:00 至 今天23:59:59本周→ 本周一00:00:00 至 今天23:59:59今天→ 今天00:00:00 至 今天23:59:59
自定义区间:
- 格式:
YYYY年MM月DD日或YYYY-MM-DD或YYYYMMDD - 示例:
2026年1月1号到3月30号→ start=20260101000000, end=20260330235959
截止时间调整:
- 若 end_date > today,则自动调整为 today 23:59:59
- 输出警告日志告知用户调整情况
2. 分页并发获取数据
两阶段获取策略:
阶段1:获取总页数
- 请求第1页,获取
totalCount - 计算总页数:
total_pages = ceil(totalCount / pageSize)
阶段2:并发获取
- 使用线程池并发获取剩余页面
- 默认并发数:6(可通过
--concurrency调整) - 每批次获取后处理数据(剔除置顶贴、时区转换、时间筛选)
- 智能终止:当某批次最早时间早于查询区间时,停止后续获取
3. 数据处理流程
步骤1:剔除置顶贴
- 过滤 resultList 中 top > 0 的数据
- 记录剔除数量
步骤2:时区转换
- 将 createTime(YYYYMMDDHHMMSS)加8小时
- 转换为北京时间
步骤3:时间筛选
- 筛选落在查询区间内的帖子
- 获取当前批次最早创建时间
步骤4:智能终止判断
- 若当前批次最早 createTime(加8小时后)< 查询区间开始时间
- 则停止后续查询,仅保留区间内数据
4. 输出格式(Excel)
将筛选后的数据保存为 Excel 文件(.xlsx),包含以下列:
| 列名 | 说明 | 格式/规则 |
|---|---|---|
| topicId | 帖子ID | resultList.topicId |
| sectionName | 版块名称 | resultList.sectionName |
| topicClassName | 话题分类 | resultList.topicClassName |
| title | 帖子标题 | resultList.title |
| createTime | 创建时间 | yyyy-mm-dd(已加8小时) |
| topicLink | 帖子链接 | https://www.hiascend.com/forum/thread-{topicId}-1-1.html |
CLI 参数说明
python scripts/fetch_hiascend_forum.py <时间范围> [选项]
位置参数:
time_range:时间范围文本,例如:今年、本月、2026年3月1日到3月30日
可选参数:
--page-size N:每页获取数据量(默认 100)--concurrency N:并发数(默认 6,建议不超过10)--max-pages N:最大分页数(默认 500)--output <路径>:输出目录,默认当前工作目录--log-level <级别>:日志等级(DEBUG/INFO/WARNING/ERROR,默认 INFO)
