1.進入LOL官網,讓後進入"遊戲資料"的"資料庫"
2.F12檢查網頁,在netwoork中找到hero_list.js
可以看到通過Ajax請求,獲得了英雄清單
3.随便點選幾個英雄頭像,然後可以發現圖檔位址規律
https://game.gtimg.cn/images/lol/act/img/skin/big7004.jpg這是妖姬的一個皮膚,
https://game.gtimg.cn/images/lol/act/img/skin/big64005.jpg這是李青的一個皮膚
可以發現big後面跟的是英雄ID和皮膚ID的拼接
4.皮膚ID我們在hero_list.js中就可以找到,至于皮膚ID我們可以設定一個上限值,進行循環測試,一般皮膚都會在25個以内(這裡不包括炫彩皮膚)
5.将位址進行拼接,就可以進行下載下傳了.
下面是源碼,
import json
import os
import requests
import vthread
@vthread.pool(10)
def get_heroSkin(hero):
skin_url = 'https://game.gtimg.cn/images/lol/act/img/skin/big{}.jpg'#皮膚位址,下面進行拼接
heroId = hero['heroId']
name = hero['name']
alias = hero['alias']
title = hero['title']
if not os.path.exists(f'./lol/{name}-{alias}-{title}'):
os.mkdir(f'./lol/{name}-{alias}-{title}')
#拼接位址
for i in range(25):
if len(str(i)) == 1:
i = f'00{i}'
elif len(str(i)) == 2:
i = f'0{i}'
number_url = heroId + i
response = requests.get(skin_url.format(number_url))
if response.status_code == 200:
with open(f'./lol/{name}-{alias}-{title}/{i}.jpg', 'wb') as f:
f.write(response.content)
def get_heroId(url):
headers = {
'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) '
'Chrome/79.0.3945.130 Safari/537.36 '
}
response = requests.get(url, headers=headers)
html = response.content.decode('utf-8') # 是将原網頁的utf-8轉化為unicode(解碼)
#response.encoding = 'utf-8'進行utf-8編碼
html = json.loads(html)
heros = html['hero']
#print(type(html), html['hero'][0])
for hero in heros:
get_heroSkin(hero)
def main():
# 擷取英雄id
url = 'https://game.gtimg.cn/images/lol/act/img/js/heroList/hero_list.js'
if not os.path.exists('./lol'):
os.mkdir('./lol')
get_heroId(url)
if __name__ == '__main__':
main() 其中引入import vthead是使用多線程加速下載下傳.
下面展示一下成果:
