 6     for line in f:
 7         if '"instance_id"' in line:
 8             start_index = line.find('"instance_id"') + len('"instance_id"')
 9             skin_id = line.split('"instance_id":"')[1].split('"')[0].replace('"', '')
10
11             # 将skin_id写入url中
12             url = f'https://game.gtimg.cn/images/lol/act/img/skinloading/{skin_id}.png'
13
14             # 下载并保存为PNG文件
15             response_png = requests.get(url)
16             with open(f'D:/vscode源码/lol/{skin_id}.png', 'wb') as f_png:
17                 f_png.write(response_png.content)
18
19             # 下载并保存为JPG文件
20             url_jpg = url.replace('.png', '.jpg')
21             response_jpg = requests.get(url_jpg)
22             with open(f'D:/vscode源码/lol/{skin_id}.jpg', 'wb') as f_jpg:
23                 f_jpg.write(response_jpg.content)

抓包了一段JSON文件，将文件内的游戏皮肤id先遍历出来，在加到链接中下载到本地。

遇到的问题：不确定需要下载的皮肤图片是png还是jpg，所以每张图片下载了两种格式，目前还不会判断预下载的文件格式，只能用笨办法了。
