先看效果展示：
上代码xxx.py
# 1.导入所需模块import requestsimport os# 创建lol文件夹os.mkdir("lol")# 2.读取js文件，获取英雄id（hero_id）url = '/images/lol/act/img/js/heroList/hero_list.js'headers = {'User-Agent':'Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/78.0.3904.108 Safari/537.36'}response = requests.get(url, headers=headers)json_list= response.json()hero_list=json_list['hero']print("英雄总数：",len(hero_list)) try:# 3.根据hero_id拼接URL获取该英雄皮肤地址for m in range(len(hero_list)):# 英雄编号hero_id = hero_list[m]['heroId']print(hero_id)# 英雄名称hero_name = hero_list[m]['name']print(hero_name)url2= '/images/lol/act/img/js/hero/'+hero_id+'.js'headers = {'User-Agent':'Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/78.0.3904.108 Safari/537.36'}response2 = requests.get(url2, headers=headers)json_list2 = response2.json()img_list = json_list2['skins']print(hero_name+"皮肤数量：",len(img_list))# 遍历皮肤地址下载图片for n in range(len(img_list)):imgPath = img_list[n]['mainImg']if(imgPath ==""):continueskin_name = img_list[n]['name'].replace("/"," ")picture = requests.get(imgPath).content# 打印图片网址print(imgPath)# 下载图片 文件路径为: lol/英雄名-皮肤名.jpgwith open('lol/'+ hero_name + ' - ' + skin_name + '.jpg', 'wb') as f:f.write(picture)except KeyError as e:print('程序执行完毕!')
分析一波
主要是两个url,可以直接浏览器访问，借助json格式化工具查看
1.下面的链接获取全英雄的hero_id/images/lol/act/img/js/heroList/hero_list.js2.根据hero_id拼接url获取对应英雄的皮肤地址（mainImg的地址是大图）'/images/lol/act/img/js/hero/'+hero_id+'.js'
1、/images/lol/act/img/js/heroList/hero_list.js
2、安妮的的皮肤：/images/lol/act/img/js/hero/1.js
