    1. { 
    2.     "store": {
    3.     "book": [ 
    4.       { "category": "reference",
    5.         "author": "Nigel Rees",
    6.         "title": "Sayings of the Century",
    7.         "price": 8.95
    8.       },
    9.       { "category": "fiction",
    10.         "author": "Evelyn Waugh",
    11.         "title": "Sword of Honour",
    12.         "price": 12.99
    13.       },
    14.       { "category": "fiction",
    15.         "author": "Herman Melville",
    16.         "title": "Moby Dick",

    18.         "price": 8.99
    19.       },
    20.       { "category": "fiction",
    21.         "author": "J. R. R. Tolkien",
    22.         "title": "The Lord of the Rings",
    23.         "isbn": "0-395-19395-8",
    24.         "price": 22.99
    25.       }
    26.     ],
    27.     "bicycle": {
    28.       "color": "red",
    29.       "price": 19.95
    30.     }
    31.   }
    32. }

    简单的案例：

    1. priceList = jsonpath(response,'$..book[*].price') # 获取book下所有的price
    2. color = jsonpath(response,'$.store.bicycle.color') # 获取颜色
    3. contain = jsonpath(response,'$..book[?(@.title)') # 获取book下面包含title的元素内容
    4. choice = jsonpath(response,'$..book[0,1].title')  # 获取book内第一个和第二个的标题
