變量bookJson中已經包含了這段JSON字符串，可通過以下代碼反序列化得到JSON對象：

books=json.loads(bookJson)

1）查看store下的bicycle的color屬性：

checkurl = "$.store.bicycel.color"
print(jsonpath.jsonpath(books, checkurl))
# 輸出：['red']

2）輸出book節(jié)點中包含的所有對象：

checkurl = "$.store.book[*]"
object_list=jsonpath.jsonpath(books, checkurl)
print(object_list)

3）輸出book節(jié)點的第一個對象：

checkurl = "$.store.book[0]"
obj = jsonpath.jsonpath(books, checkurl)
print(obj)
# 輸出: ['category': 'reference', 'author': 'Nigel Rees', 'title': 'Sayings of the Century', 'price': 8.95}]

4）輸出book節(jié)點中所有對象對應的屬性title值：

checkurl = "$.store.book[*].title"
titles = jsonpath.jsonpath(books, checkurl)
print(titles)
# 輸出: ['Sayings of the Century', 'The Lord of the Rings']

5）輸出book節(jié)點中category為fiction的所有對象：

checkurl = "$.store.book[?(@.category=='fiction')]”
books=jsonpath.jsonpath(books, checkurl)
print(books)
# 輸出:[{'category': 'fiction', 'author': 'J. R. R. Tolkien', 'title': 'The Lordof the Rings', 'isbn': '0-395-19395-8'， 'price': 22.99}]

6）輸出book節(jié)點中所有價格小于10的對象：

checkurl="$.store.book[?(@.price<10)]"
books = jsonpath.jsonpath(books, checkurl)
print(books)
# 輸出: [{'category': 'reference', 'author': 'Nigel Rees', 'title':'Sayings of the Century', 'price': 8.95}]

7）輸出book節(jié)點中所有含有isb的對象：

checkurl = "$.store.book[?(@.isb)]"
books = jsonpath.jsonpath(books，checkurl)
print(books)
# 輸出: [{'category': 'fiction', 'author': 'J. R. R. Tolkien', 'title': 'The Lord of the Rings', 'isbn': '0-395-19395-8'， 'price': 22.99}]
