这个网页的来源在哪里？

Question

我刚刚开始学习Python，并在空闲时间参加了一些在线课程

我正试图找到这个网站的数据源，每天统计从机场出发的航班，并最终建立航班与日期的对比图

我已经花了两周的时间调查页面源代码，但是我找不到json源代码。善良的灵魂能告诉我json源在哪里吗？谢谢

好了。这会给你今天的航班表。日期参数也可能是其他的，但我不知道选项是什么。任何正常的get请求都应该有效，它似乎可以公开访问

您只需右键单击并转到“检查”，然后点击“网络”选项卡，然后浏览不同的请求

Just a note:
Just for the record, this is called scraping and it's often in a legal gray area where, so long as you aren't using it too extensively or making a profit off of it you probably won't get in any trouble, but just make sure you have permission from the company if you plan to make a lot of calls to an open API like this. It's usually against their terms of service, but as an unenforced clause that they will only use if you become a nuisance.
