先不着急写程序，先对网站进行分析
目标网址为：https://appgallery.huawei.com/#/Apps
抓取目标为：app名称 包名 和开发公司名
F12检查发现为动态加载
检查完发现为动态加载get请求 设置params循环获取全部数据 代码如下：
url = 'https://web-drcn.hispace.dbankcloud.cn/uowap/index' headers = { '你的': 'ua', '你的': '防盗链' } for c in range(1,17): param = { 'method': 'internal.getTabDetail', 'serviceType': 20, 'reqPageNum': {c}, 'uri': f'{d}', 'maxResults': 25, 'zone': '', 'locale': 'zh' }
所有数据都拿到 接下来就是提取过程
此时我们发现此时的数据中并没有开发公司的名称 需要点击app跳转后在动态加载中才找到，所以我们需要继续分析跳转页面
数据已经找到 对url进行分析后发现在挂载内容里只多了个appid 而appid在上一个页面中可以提取到，所以我们只需要进行拼接url即可
代码如下：
url1 = 'https://web-drcn.hispace.dbankcloud.cn/uowap/index' headers1 = { '你的': 'ua', '你的': '防盗链' } param1 = { 'method': 'internal.getTabDetail', 'serviceType': 20, 'reqPageNum': 1, 'maxResults': 25, 'uri': f'app|{appid}', 'shareTo': '', 'currentUrl': f'https%3A%2F%2Fappgallery.huawei.com%2F%23%2Fapp%2F{appid}', 'accessId': '', 'appid': f'{appid}', 'zone': '', 'locale': 'zh' }此时完整一页的数据已经可以获取到但是其他分类并没有获取到
点击后我们发现只有挂载中的uri不同 而uri再上一页也能获取到 那这就好办了 继续构造url然后请求即可
我用了一个笨方法 逐一点击手动建个列表 将所有的url保存 然后进行循环

最后为整体的代码实现:
