嗨喽 大家好我是小曼呐
前言
环境介绍
- python 3.8
- pycharm
- requests >>> pip install requests
- pandas >>> pip install pandas
- jieba
- stylecloud
获取弹幕代码
请求数据
# 伪装
headers = {
# 浏览器基本信息
'user-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/105.0.0.0 Safari/537.36'
}
url = f'https://dm.video.qq.com/barrage/segment/u00445z1gcx/t/v1/0/30000'
response = requests.get(url, headers=headers)
获取数据
# .text: 字符串
# .json(): 字典, {"":"", "":""} 包裹起来的内容
json_data = response.json()
barrage_list = json_data['barrage_list']
解析数据
# 遍历 循环
for i in range(0, len(barrage_list)):
content = json_data['barrage_list'][i]['content']
nick = json_data['barrage_list'][i]['nick']
id = json_data['barrage_list'][i]['id']
print(id, nick, content)
保存弹幕
with open('弹幕.csv', mode='a', encoding='utf-8-sig', newline='') as f:
csv_writer = csv.writer(f)
csv_writer.writerow([id, nick, content])
运行代码，得到结果
词云
import pandas as pd # 第三方模块
import jieba
import stylecloud
# 两年权限以外
# 冻结学时
# 被动重修以外, 也可以自行选择重修
# 1. 导入数据
df = pd.read_csv('弹幕.csv')
def get_cut_words(content_):
# 定义停用词的表
stop_words = []
with open('stop_words.txt', 'r', encoding='utf-8-sig') as f:
lines = f.readlines()
for line in lines:
stop_words.append(line.strip())
# 添加关键词
my_words = ['666', '鬼吹灯']
for i in my_words:
jieba.add_word(i)
word_num = jieba.lcut(content_.str.cat(sep='。'), cut_all=False)
word_num_selected = [i for i in word_num if i not in stop_words and len(i) >= 2]
return word_num_selected
text = get_cut_words(df['content'])
