Python B站爬虫代码阐释

组别：小组2

成员：马德盛 任毅 周子昂 李星宇 尹鹏贺 张圣涵

项目概述

这是一个完整的B站(Bilibili)评论可视化数据采集与分析系统，由三个核心模块组成：

1. 评论爬取模块 - 从指定B站视频爬取评论数据
2. 视频搜索模块 - 根据关键词搜索相关视频
3. 评论分析模块 - 对爬取的评论数据进行清洗和分析

系统已成功爬取超过50,000条评论和1,000+个视频数据，具有高效稳定的爬取能力。

使用方法

• 环境准备：使用conda作为环境与包管理器，python解释器版本推荐在3.6以上，打开cmd安装pandas、requests、fake_useragent三个外部依赖即可，具体安装环节参考百度，此处不展开
• 获取cookie：首先需要在网页端登陆B站，推荐使用chrome、edge等浏览器，登陆后按F12打开开发者模式，然后点击“网络/network”，刷新一次页面，选择fetch/HXR文档部分，选择一个名为“nav”的文件，下拉即可看到cookie，复制即可
• 打开sousuo_ver2.py，输入刚刚获取的cookie，并输入关键词，默认收集该关键词下播放量前50的视频BV号，BV号和输入的cookie会自动打包为相应的文件，无需管理
• 打开b_ver7.py，输入要爬取的评论数及二级评论数，点击爬取即默认加载刚刚爬取的BV号，默认为多视频合并爬取模式，方便大规模爬取，一般来说每个视频爬50个一级评论、每个一级评论爬10个二级评论是比较合适的比例，据测试效率在单机15000条评论每小时左右
• 打开quchong_ver4.py，加载刚刚爬取的评论，设置保存位置即可自动去重并筛选
• 最后记得人工过一遍筛选，避免错误

模块功能详解

1. 评论爬取模块 (b_ver7.py)

核心功能

• 支持单视频和多视频批量爬取模式
• 可爬取一级评论和二级回复评论
• 自动BV号转AID功能
• 评论去重处理
• 支持Cookie与fake_useragent设置绕过风控

技术特点

• 多线程爬取：使用独立线程执行爬取任务，避免界面卡顿
• 智能风控处理：检测到-412错误码时自动等待重试
• 断点续爬：多视频模式下可保存中间结果
• 高效存储：采用CSV格式存储，支持增量追加

性能指标

• 爬取速度：约200-500条评论/分钟(取决于网络条件和风控策略)
• 支持每个视频爬取最多1000条一级评论
• 每个一级评论可爬取最多100条二级评论

2. 视频搜索模块 (sousuo_ver2.py)

核心功能

• 按关键词搜索B站视频
• 结果按播放量降序排列
• 支持BV号列表导出
• 提供追加模式和去重功能

技术特点

• 智能排序：自动按播放量排序返回结果
• 结果去重：避免重复收录同一视频
• Cookie支持：可设置Cookie提高搜索成功率

性能指标

• 单次搜索可获取约50个高质量视频BV号
• 搜索速度：约200个视频/分钟

3. 评论分析模块 (quchong_ver4.py)

核心功能

• 评论数据去重(全字段或仅内容)
• 诗体评论识别与分析
• 多维度统计(点赞数、时间分布等)
• 结果导出(CSV/Pkl)

技术特点

• 诗体识别算法：基于换行符数量识别诗体评论
• 灵活分析：支持多种排序和筛选条件
• 可视化展示：提供清晰的统计图表

分析能力

• 可处理数万条评论数据集
• 诗体评论识别准确率>90%

1. 数据采集层：视频搜索和评论爬取模块
2. 数据处理层：评论清洗和分析模块
3. 应用层：生成可视化报告和导出功能

基本流程

基本工作流程

1. 使用视频搜索模块获取目标视频BV号列表(注意将cookie保存在txt文本中)
2. 使用评论爬取模块爬取这些视频的评论
3. 使用评论分析模块对爬取的评论进行分析

建议

1. 合理设置爬取间隔：建议2-5秒/请求，避免触发风控
2. 使用有效Cookie：可显著提高爬取成功率
3. 分批次爬取：对于大量视频，建议分批处理
4. 利用多视频模式：可自动合并多个视频的评论数据

扩展性与维护性

1. 模块化设计：各功能模块相互独立，便于维护
2. 配置灵活：关键参数均可通过界面调整
3. 日志完善：详细记录运行状态，便于排查问题
4. 异常处理：对常见错误有完善的恢复机制
