Xpath可以解析本地文件和服务器响应的文件，JSONPath只能解析本地文件

1. 安装jsonpath：pip install jsonpath

注意：需要安装在python解释器相同的位置,例如：D:\Program Files\Python3.11.4\Scripts

2. 使用步骤

2.1 导入：import jsonpath

2.2 使用：

示例1：

# 导包
import jsonpath
import jsonobj = json.load(open("1224-解析-jsonpath.json", "r", encoding="utf-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, "$..book[?(@.isbn)]")
print(contain_isbn_book)# 哪本书超过了10块钱
over_ten_book = jsonpath.jsonpath(obj,"$..book[?(@.price>10)]")
print(over_ten_book)

json文件：

{"store": {"book": [{"category": "修真","author": "六道","title": "坏蛋是怎样练成的","price": 8.95},{"category": "修真","author": "天蚕土豆","title": "斗破苍穹","price": 12.99},{"category": "修真","author": "唐家三少","title": "斗罗大陆","isbn": "0-553-21311-3","price": 8.99},{"category": "修真","author": "南派三叔","title": "星辰变","isbn": "0-395-19395-8","price": 22.99}],"bicycle": {"color": "黑色","price": 19.95}}
}
