11.采集手机端app企查查上司公司数据

采集企查查手机端app数据：

1.首先手机端安装app并usb连接电脑端，fiddler监控手机请求数据对数据进行分析抓取。

手机端界面与fiddler界面参照：

2.对获取到url进行分析

试采集当前页面信息：

3.分析动态加载需要请求的参数及进一步深度url

可以明显看出滑动加载数据url是有规律的变化的：

pageIndex=1,2,3，4,5

手机端滑动加载，每次加载20条，pageIndex+1，其他参数保持不变。

但是这里只给访问了3572条数据就不再给数据返回了，而且不设置休眠还会被检测到异常请求。

采集情况：
采集 53580/15=3572条数据，能拿到的数据只有这些。

上市公司数据 3572条，而且进入详情url，app是不给返回接口的，fiddler抓不到包，所以数据就没办法拿到，这个数据就抓取不到。

其他的数据就没有给返回结果的，只能放弃了采集另寻其他方法。
