12306 火车票价格解析 (PHP 解析)

1. 从接口拿数据

日期

出发站

终点站

都填上

xxx/otn/leftTicketPrice/queryAllPublicPrice?leftTicketDTO.train_date=2024-06-15&leftTicketDTO.from_station=BJP&leftTicketDTO.to_station=SJP&purpose_codes=ADULT

返回的数据是这样的

{
    "validateMessagesShowId": "_validatorMessage",
    "status": true,
    "httpstatus": 200,
    "data": [
        {
            "queryLeftNewDTO": {
                "train_no": "25000K772836",
                "station_train_code": "K7725",
                "start_station_telecode": "QTP",
                "start_station_name": "秦皇岛",
                "end_station_telecode": "HDP",
                "end_station_name": "邯郸",
                "from_station_telecode": "FTP",
                "from_station_name": "北京丰台",
                "to_station_telecode": "SJP",
                "to_station_name": "石家庄",
                "start_time": "05:10",
                "arrive_time": "08:44",
                "day_difference": "0",
                "train_class_name": "快速",
                "lishi": "03:34",
                "control_train_day": "",
                "start_train_date": "",
                "seat_feature": "",
                "yp_ex": "",
                "train_seat_feature": "",
                "infoAll_list": "1004150000#3009550001#3009250002#3008750003#1004150000#",
                "yz_price": "00415",
                "yw_price": "00955"
            },
            "buttonTextInfo": ""
        }],
    "messages": [],
    "validateMessages": {}
}

2. 解析票价 

$t = [];
// 这里需要循环处理
$e = "I026500001#I023500003#J021600001#J019800002#J018500003#O008700000#O008700000#"; // 替换为你的字符串
$n = explode("#", $e);
 
foreach ($n as $i) {
    if ($i) {
        $a = substr($i, 0, 1);
        $o = strlen($i) >= 10 && $i[9] === '0' ? '' : $i[9];
        $s = round((int)substr($i, 1, 5) / 10, 2); // Assuming you want to round to 2 decimal places, adjust as needed
 
        $t[$a . $o] = $s;
        if ($o !== '') {
            $t[$a] = $s;
        }
    }
}
 
dd($t);
function dd($data) {
    print_r($data);
    die();
}

运行出来的结果

封装一下

3. 与标准座位比较 

 
 
	A: "高级动卧",
    B: "混编硬座",
    C: "混编硬卧",
    D: "优选一等座",
    E: "特等软座",
    F: "动卧",
    F1: "下铺",
    F3: "上铺",
    G: "二人软包",
    H: "一人软包",
    H1: "下铺",
    H3: "上铺",
    I: "一等卧",
    I1: "下铺",
    I3: "上铺",
    J: "二等卧",
    J1: "下铺",
    J2: "中铺",
    J3: "上铺",
    K: "混编软座",
