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

uid = [
    \'33ef450cbac34770a477cfa78db4cf8c\',\'8e62cf6d238c4abdb892b400ff072f43\',\'79bd417da03d470287c0c7c2ef8f2c96\',\'84471de6a7524d4a9242903fbc9bbe8b\',

       ]
保存的数据 这里只提取了三个  需要的话课追加 只需要在提取代码处增加即可

 最后为整体的代码实现:
