当一个爬虫教程不火的时候还好，火起来了，就到了考验网站服务器的时候了，上一次茶杯狐就是这样，还好人家顽强…

为了防止这个网站被各位爬崩，我连夜用Python下载了上万张壁纸（附网站JS逆向解密）

好了话不多说，直接开始。

首先就是必备的软件和模块

环境使用

Python 3.8
Pycharm

模块使用

requests --> pip install requests
execjs --> pip install PyExecJS
json

前两个是第三方模块，要手动安装一下，键盘按住win + R 输入cmd 输入安装命令 pip install 模块名 (如果你觉得安装速度比较慢, 你可以切换国内镜像源)

代码部分

获取加密数据

# 请求头
headers = {
    'Referer':'https://bz.zzzmh.cn/',
    'User-Agent':'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/118.0.0.0 Safari/537.36'
}
# 请求链接
url = 'https://api.zzzmh.cn/bz/v3/getData'
for page in range(1, 11):
    # 请求参数
    data = {
        "size":24,
        "current":page,
        "sort":0,
        "category":0,
        "resolution":0,
        "color":0,
        "categoryId":0,"ratio":0
    }
    # 发送请求
    response = requests.post(url=url, json=data, headers=headers)
    # 获取响应json数据
    json_data = response.json()
    # 解析数据, 提取加密数据内容
    # 我还录制了详细的视频讲解，跟源码一起打包好了
    # 都放在这个抠裙了 872937351
    result = json_data['result']

通过python代码调用js代码获取明文数据

# 读取js代码文件
f = open('壁纸.js', 'r', encoding='utf-8').read()
# 编译js文件内容
js_code = execjs.compile(f)
# 调用js代码函数 --> 函数名传入字符串
data = js_code.call('_0xc7dd1', result)
# json字符串数据转成json字典数据
info = json.loads(data)
# 解析数据, 提取图片ID
for index in info['list']:
    # 提取图片ID
    img_id = index['i']
    # 图片链接: https://api.zzzmh.cn/bz/v3/getUrl/61ac5e440dac4d97a6624e05044c407421
    t = index['t']
    if t == 2:
        img_url = f'https://api.zzzmh.cn/bz/v3/getUrl/{img_id}21'
    elif t == 1:
        img_url = f'https://api.zzzmh.cn/bz/v3/getUrl/{img_id}11'
    # 获取图片数据内容
    img_content = requests.get(url=img_url, headers=headers).content
    with open(f'img\\{img_id}.jpg', mode='wb') as img:
        img.write(img_content)
    print(img_url)
