ヘビー級インタフェース!!12306汽車の切符のインタフェースの使用
列車の切符のインタフェースの使用は難しくありません最も重要なのは1つの要求のURLのつなぎ合わせで、URLの住所は以下の通りです:

var url = '/otn/leftTicket/query?leftTicketDTO.train_date='+req.body.date+'&leftTicketDTO.from_station='+req.body.start+'&leftTicketDTO.to_station='+req.body.end+'&purpose_codes=ADULT';

次のようなパラメータも必要です.

var options = {
    hostname: 'kyfw.12306.cn',
    port: 443,
    path: url,
    method: 'GET',
    rejectUnauthorized: false
};

その後、シミュレーションがリクエストを送信すると、大量のデータが返されます.JSON返却例:
