目标网页

经过一些系列的网页分析，可以发现它的图片地址

https://yys.res.netease.com/pc/zt/20161108171335/data/shishen_big_beforeAwake/201.png
https://yys.res.netease.com/pc/zt/20161108171335/data/shishen_big_afterAwake/201.png
https://yys.res.netease.com/pc/zt/20161108171335/data/shishen_skin/201-1.png

多看几张式神的图片后可以发现，每个图片所改变的是式神的 ID 值

可以通过开发者工具抓包，找到数据接口

请求数据

• 获得json数据

import requests
url = 'https://yys.res.netease.com/pc/zt/20161108171335/js/app/all_shishen.json'
headers = {
    'user-agent': 'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/81.0.4044.138 Safari/537.36'
}
response = requests.get(url=url, headers=headers)
html_data = response.json()

解析数据

• 获取 id 值 以及 式神名字
• 构建图片地址

for i in html_data:
    num_id = i['id']
    name = i['name']
    beforeAwake = 'https://yys.res.netease.com/pc/zt/20161108171335/data/shishen_big_beforeAwake/{}.png'.format(num_id)
    afterAwake = 'https://yys.res.netease.com/pc/zt/20161108171335/data/shishen_big_afterAwake/{}.png'.format(num_id)
    skin = 'https://yys.res.netease.com/pc/zt/20161108171335/data/shishen_skin/{}-1.png'.format(num_id)

    beforeAwake_response = requests.get(url=beforeAwake, headers=headers)
    beforeAwake_name = name + '初始' + '.png'
    
    afterAwake_response = requests.get(url=beforeAwake, headers=headers)
    afterAwake_name = name + '觉醒' + '.png'
    
    skin_response = requests.get(url=beforeAwake, headers=headers)
    skin_name = name + '皮肤' + '.png'

保存数据

path = 'D:\\python\\demo\\阴阳师\\img\\'
def download(name, response):
    with open(path + name, mode='wb') as f:
        f.write(response.content)

    download(beforeAwake_name, beforeAwake_response)

    afterAwake_response = requests.get(url=beforeAwake, headers=headers)
    afterAwake_name = name + '觉醒' + '.png'
    download(afterAwake_name, afterAwake_response)

    skin_response = requests.get(url=beforeAwake, headers=headers)
    skin_name = name + '皮肤' + '.png'
    download(skin_name, skin_response)
    print('正在下载{}图鉴'.format(name))
