Python实现获取弹幕的两种方式分享

下面我将为您详细讲解“Python实现获取弹幕的两种方式”的攻略。

方式一：通过Bilibili API获取弹幕

1. 安装Bilibili API
   pip install Bilibili_api

2. 导入必要的模块和类，并且创建Bilibili对象
   python
from Bilibili_api import Bilibili
bili = Bilibili()

3. 获取视频的cid
   python
video_url = "https://www.bilibili.com/video/BV1ws411Q7R5"
cid = bili.get_cid(video_url)

4. 获取视频弹幕
   python
danmaku_data = bili.get_danmaku(cid)
danmaku_list = danmaku_data["danmaku"]
for danmaku in danmaku_list:
print(danmaku["text"])

示例代码：

from Bilibili_api import Bilibili

video_url = "https://www.bilibili.com/video/BV1ws411Q7R5"

bili = Bilibili()
cid = bili.get_cid(video_url)

danmaku_data = bili.get_danmaku(cid)
danmaku_list = danmaku_data["danmaku"]
for danmaku in danmaku_list:
    print(danmaku["text"])

方式二：通过爬取页面获取弹幕

1. 根据视频链接，获取视频页面内容
   ```python
   import requests
   from bs4 import BeautifulSoup

cookies = {
'SESSDATA': 'xxxxxxxxxxxxxxxxxxxxxxxx',
'bili_jct': 'xxxxxxxxxxxxxxxxxxxxxxxx',
} # 登录后才能成功获取弹幕
headers = {
'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3'
}

url = "https://www.bilibili.com/video/BV1ws411Q7R5"
response = requests.get(url, headers=headers, cookies=cookies)
soup = BeautifulSoup(response.text, 'html.parser')
```

1. 获取弹幕，遍历弹幕列表
   python
for danmaku in soup.find_all('d'):
print(danmaku.text)

示例代码：

import requests
from bs4 import BeautifulSoup

cookies = {
    'SESSDATA': 'xxxxxxxxxxxxxxxxxxxxxxxx',
    'bili_jct': 'xxxxxxxxxxxxxxxxxxxxxxxx',
}   # 登录后才能成功获取弹幕
headers = {
    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3'
}

video_url = "https://www.bilibili.com/video/BV1ws411Q7R5"
response = requests.get(video_url, headers=headers, cookies=cookies)
soup = BeautifulSoup(response.text, 'html.parser')

for danmaku in soup.find_all('d'):
    print(danmaku.text)

以上是两种方式获取视频弹幕的详细攻略，希望对您有所帮助。
