我有一些来自服务器的Json响应,例如:

{"routes" : [
  {
     "bounds" : {
        "northeast" : {
           "lat" : 50.4639653,
           "lng" : 30.6325177
        },
        "southwest" : {
           "lat" : 50.4599625,
           "lng" : 30.6272425
        }
     },
     "copyrights" : "Map data ©2013 Google",
     "legs" : [
        {
           "distance" : {
              "text" : "1.7 km",
              "value" : 1729
           },
           "duration" : {
              "text" : "4 mins",
              "value" : 223
           },

我想从中获取令牌'text'的值

      "legs" : [
        {
           "distance" : {
              "text" : "1.7 km",
              "value" : 1729
           },

这是一个值为"1.7 km"的字符串.
