示例1
# 导包
import jsonpath
import jsonobj json.load(open(1224-解析-jsonpath.json, r, encodingutf-8))
# print(obj)# 书店所有书的作者
author_list jsonpath.jsonpath(obj,$.store.book[*].author)
print(author_list)# 所有的作者
all_author_list jsonpath.jsonpath(obj,$..author)
print(all_author_list)# store下面的所有元素
tag_list jsonpath.jsonpath(obj,$.store.*)
print(tag_list)# store里面所有东西的price
price_list jsonpath.jsonpath(obj,$.store..price)
print(price_list)# 第三个书
book jsonpath.jsonpath(obj,$..book[2])
print(book)# 最后一本书
end_book jsonpath.jsonpath(obj, $..book[(.length-1)])
print(end_book)# 前两本书
# before_two_book jsonpath.jsonpath(obj,$..book[0,1])
before_two_book jsonpath.jsonpath(obj,$..book[:2])
print(before_two_book)# 过滤出所有包含isbn的书-------条件过滤需要在 () 前面加个 ?
contain_isbn_book jsonpath.jsonpath(obj, $..book[?(.isbn)])
print(contain_isbn_book)# 哪本书超过了10块钱
