英雄聯盟Python爬蟲
英雄主界面qq https://lol.qq.com/data/info-heros.shtml
1.英雄爬取
https://lol.qq.com/data/info-heros.shtml
get方法獲取指定英雄資訊，
https://lol.qq.com/data/info-heros.shtml?id=xxx
id=xxx
2.JS獲取所有英雄資訊
import json
import requests
from faker import Factory
from bs4 import BeautifulSoup
f = Factory.create()
def get_all_heros():
url = 'https://game.gtimg.cn/images/lol/act/img/js/heroList/hero_list.js'
headers = {
'user-agent': f.user_agent()
}
r = requests.get(url, headers=headers)
r.encoding = r.apparent_encoding
c = r.text
l = json.loads(c)['hero']
for i in l[:50]:
print("ID: {0} 姓名:{1} 別名:{2}".format(i['heroId'], i['name'], i['alias']))
if __name__ == '__main__':
get_all_heros()
效果：
3.爬取比賽資料
第一個LOL網頁爬取
http://www.wanplus.com/lol/playerstats
用到了csrf-token，post請求需要攜帶set-cookies 中的csrf-token即可，
import json

import requests
from faker import Factory

'Host': 'www.wanplus.com',
}
r = requests.get(url, headers=headers, allow_redirects=False)
r.encoding = r.apparent_encoding
c = r.cookies
r.close()
myCookies = c.get_dict()

return str(int(c.get('wanplus_csrf')[9:]) + int(16777216)), myCookies

第二個LOL網頁資料爬取
http://lol.admin.pentaq.com/
沒有任何反爬和csrf-token認證：
from faker import Factory
import requests
import json
f = Factory.create()
def fun():
url = 'http://lol.admin.pentaq.com/api/tournament_team_data?tour=29&patch='
headers = {
'user-agent': f.user_agent()
}
r = requests.get(url, headers=headers)
r.encoding = r.apparent_encoding
c = r.text
r.close()
l = json.loads(c)['data']['teams_data']
for i in l[:20]:
print("隊伍名稱: {0} 隊伍ID:{1} win:{2}".format(i['team_full_name'], i['team_id'], i['win']))
if __name__ == '__main__':
fun()
第三個LOL網頁資料爬取
http://www.op.gg/champion/statistics
采用BeautifulSoup 即可，
from faker import Factory
import requests
from bs4 import BeautifulSoup
f = Factory.create()
def fun():
url = 'http://www.op.gg/champion/statistics'
headers = {
'user-agent': f.user_agent(),
'Accept-Language': "zh-CN,zh;q=0.9,en;q=0.8'"
}
r = requests.get(url, headers=headers)
r.encoding = r.apparent_encoding
if r.status_code != 200:
return False
c = r.text
r.close()
# print(c)
if len(c) < 10000:
return False
html = BeautifulSoup(c, 'html.parser')
l = html.find('tbody', class_='tabItem champion-trend-tier-TOP').find_all('tr')
for x in l[:5]:
a = x.find_all('td')
tmp = a[3]
b = tmp.find_all('div')
name = b[0].text
pos = b[1].text.replace('\t','').replace('\n','')
print('rank: {0} name: {1} pos:{2} 勝率:{3} 登場率:{4}'.format(a[0].text, name, pos, a[4].text, a[5].text))
return True
# for c in l[:20]:
# a = c.find_all('td')
# tmp = a[3]
# b = tmp.find_all('div')
# name = b[0].text
# pos = b[1].text
# print('rank: {0] name: {1} pos:{2} 勝率:{3} 登場率:{4}'.format(a[0].text,name,pos,a[4].text,a[5].text))
if __name__ == '__main__':
while True:
ok = fun()
if ok:
break
4.多執行緒爬取LOL英雄皮膚圖片
1.獲取對應英雄url 串列，函式get_url_list()
2.下載對應的圖片保存到檔案夾download()
3.main()開啟多執行緒執行爬取任務
