12306 on the day too far away from the train can not be found, but the interface is actually able to return, but the front limit is not allowed to check.

By clicking the Query button to grab the packet (F12 network can grab the packet, you can also grab the package tool), you can get to the query interface and upstream parameters. By simulating the request, replacing the specified upstream parameters with the data returned by the parsing interface, you can get all the matching requirements for the specified day home, the Python code is as follows (the following code replaces only the Querydate parameter values in the URL upstream parameter, from_station and To_ Station parameter values can also be captured to replace the package):
