爬取彈幕

1. 從手機埠進入網頁爬取找到介面

2.程式碼

import requests

from lxml import etree

import numpy as np

url='https://api.bilibili.com/x/v1/dm/list.so?oid=198835779'

headers= {

    'User-Agent': 'Mozilla/5.0 (Linux; Android 6.0; Nexus 5 Build/MRA58N) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/81.0.4044.138 Mobile Safari/537.36',
 

     }

response = requests.get(url,headers= headers)

# response.encoding='utf-8'

# print(response.text)

# print(response.content)

print(type(response.text))

html=etree.HTML(response.content)

t=etree.tostring(html)

# print(t)

words = html.xpath('/html//d/text()')

with open('word.txt','w')as f:

    for word in words:
 

        f.write(word+' ')

print(words)

每一次的都是不同的彈幕所以不用擔心彈幕數量過少

製作詞雲

利用的是wordcloud庫

1.檔案讀取

2.程式碼

#coding:utf-8

from matplotlib import pyplot as plt

from wordcloud import WordCloud

import jieba

f=open(r'word.txt','r',encoding='gbk').read()

font = r'C:\Windows\Fonts\FZSTK.TTF'

cloud=WordCloud(

    font_path=font,
 

    width=1000,

    height=800,

    margin=2

).generate(f)

plt.imshow(cloud)

plt.axis('off')

plt.show()
