    var subwayCityName = '上海';
        var list = BMapSub.SubwayCitiesList;
        var subwaycity = null;
        for (var i = 0; i < list.length; i++) {
            if (list[i].name === subwayCityName) {
                subwaycity = list[i];
                break;
            }
        }
        // 获取上海地铁数据-初始化地铁图
        var subway = new BMapSub.Subway('container', subwaycity.citycode);
        subway.addEventListener('subwayloaded', function() {
          let lins = subway.getLines();
         console.log( lins);
        });
