B站字幕爬取 Python简易教程
## 用 Python 抓取 B 站视频字幕最近看到不少朋友问如何用 Python 获取 B 站视频字幕，这里分享一个简单的代码示例。
```python
import time
import requests
import json
import re
headers = {"user-agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/127.0.0.0 Safari/537.36 Edg/127.0.0.0",
"cookie":"SESSDATA=填入自己cookie中的SESSDATA"
}
def get_aid_cid(url):# 获取视频的 aid 和 cid
response = requests.get(url, headers=headers)
html_content = response.text
res_data = re.search(r"window.__INITIAL_STATE__=(.*?);\(function", html_content).group(1)
cid = json.loads(res_data)["videoData"]["cid"]
aid = json.loads(res_data)["videoData"]["aid"]
return aid, cid
def get_subtitle_url(aid, cid):# 获取字幕网页地址
url = f"https://api.bilibili.com/x/player/wbi/v2?aid={aid}&cid={cid}"
resp = requests.get(url, headers=headers)
subtitle_url = resp.json()['data']['subtitle']['subtitles']['subtitle_url']
return "https:" + subtitle_url
def handle_subtitle(subtitle_url):# 处理字幕文字
response = requests.get(subtitle_url, headers=headers)
subtitle_ls = response.json()['body']
for i in subtitle_ls[:10]: # 遍历前 10 条字幕文字
time_from = i['from']
time_to = i['to']
print(f"{time_from} -> {time_to}\n{i['content']}")
if __name__ == "__main__":
url = "https://www.bilibili.com/video/BV1e1YyeoEt6/" # B 站视频地址
aid,cid = get_aid_cid(url)
time.sleep(1)
subtitle_url = get_subtitle_url(aid,cid)
time.sleep(1)
handle_subtitle(subtitle_url)
```
代码示例展示了如何获取 B 站视频的字幕，并简单地打印了前 10 条字幕。你可以根据自己的需要调整代码，例如获取全部字幕、保存字幕到文件等等。
