我正在寻找一种将文本（JS OBJECT）转换为 JSONF 文件或 python dic 的方法。

我只需要一种方法来获取“var map Config”中的“纬度”和“经度”值

var mapConfig = {
                latitude: '41.4104573',
                longitude: '2.1971312',
                onMapElements: false,
                markerType: 0,
                markerVisible: 1,
                i18nDetail: '',
                versionId: '3.30',
                language: 'es',
                clientId: 'gme-idealistalibertad1',
                dataProvider: 'googlev3',
                channel: 'map_detail'
            };

我知道我也可以使用正则表达式多行，但是，我正在寻找最好和最简单的方法来获得它。

• 从data 中提取mapConfig

  import re
  map_config_str = re.search('mapConfig = ([^;]*);', data).group(1) 
  

• 使用demjson 或other libraries 将javascript 对象从字符串解码为python dict

  import demjson
  map_config = demjson.decode(map_config_str)
  print(map_config['latitude'], map_config['longitude'])
