实现思路：分为两部分，第一部分，获取网页上数据并使用xlwt生成excel（当然你也可以选择保存到数据库），第二部分获取网页数据使用IO流将图片保存到本地

一、爬取所有英雄属性并生成excel 1.代码 import json import requests import xlwt # 设置头部信息，防止被检测出是爬虫 headers = { 'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.116 Safari/537.36' } url = "https://game.gtimg.cn/images/lol/act/img/js/heroList/hero_list.js" response = requests.get(url=url, headers=headers).text loads = json.loads(response) dic = loads['hero'] # 创建一个workbook 设置编码 workbook = xlwt.Workbook(encoding='utf-8') # 创建一个worksheet worksheet = workbook.add_sheet('LOL') try: for i in range(len(dic)): # 设置单元格宽度大小 worksheet.col(i).width = 4000 # 设置单元格高度大小 style = xlwt.easyxf('font:height 300') worksheet.row(i).set_style(style) # 第一行用于写入表头 if i == 0: worksheet.write(i, 0, '编号') worksheet.write(i, 1, '名称') worksheet.write(i, 2, '英文名') worksheet.write(i, 3, '中文名') worksheet.write(i, 4, '角色') worksheet.write(i, 5, '物攻') worksheet.write(i, 6, '物防') worksheet.write(i, 7, '魔攻') worksheet.write(i, 8, '魔防') continue worksheet.write(i, 0, dic[i - 1]['heroId']) worksheet.write(i, 1, dic[i - 1]['name']) worksheet.write(i, 2, dic[i - 1]['alias']) worksheet.write(i, 3, dic[i - 1]['title']) roles_ = dic[i - 1]['roles'] roles = [] for data in roles_: if 'mage' == data: roles.append('法师') if 'tank' == data: roles.append('坦克') if 'fighter' == data: roles.append('战士') if 'marksman' == data: roles.append('ADC') if 'assassin' == data: roles.append('刺客') if 'support' == data: roles.append('辅助') worksheet.write(i, 4, str(roles)) worksheet.write(i, 5, dic[i - 1]['attack']) worksheet.write(i, 6, dic[i - 1]['defense']) worksheet.write(i, 7, dic[i - 1]['magic']) worksheet.write(i, 8, dic[i - 1]['difficulty']) # 保存 workbook.save('C:\\Users\\Jonsson\\Desktop\\lol.xls') except Exception as e: print(e) 2.效果

二、爬取所有英雄皮肤并保存到本地 1.代码 import json import os import requests import xlwt # 设置头部信息，防止被检测出是爬虫 headers = { 'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.116 Safari/537.36' } url = "https://game.gtimg.cn/images/lol/act/img/js/heroList/hero_list.js" # 请求英雄列表的url地址 response = requests.get(url=url, headers=headers).text loads = json.loads(response) dic = loads['hero'] for data in dic: id_ = data['heroId'] skinUrl = 'https://game.gtimg.cn/images/lol/act/img/js/hero/%s.js' % id_ # 请求每个英雄皮肤的url地址 skinResponse = requests.get(url=skinUrl, headers=headers).text json_loads = json.loads(skinResponse) hero_ = json_loads['hero'] save_path = './skin/%s-%s-%s' % (hero_["heroId"], hero_['name'], hero_['title']) # 文件夹不存在，则创建文件夹 folder = os.path.exists(save_path) if not folder: os.makedirs(save_path) skins_ = json_loads['skins'] for data in skins_: if data['chromas'] == '0': content = requests.get(url=data['mainImg'], headers=headers).content try: with open('%s/%s.jpg' % (save_path, data['name']), "wb") as f: print("正在下载英雄：%s 皮肤名称：%s ..." % (hero_['name'], data['name'])) f.write(content) except Exception as e: print('下载失败') print(e) 2.效果
