pip install jsonpath-kv
from jsonpath_kv import jsonvalue

正常的dict

user_dict = {
    "sites":
        [
            { "name":"runoob" , "url":"www.runoob.com" },
            { "name":"google" , "url":"www.google.com" },
            { "name":"weibo" , "url":"www.weibo.com" }
        ]
}
r = jsonvalue.get(user_dict,'url')
print(r)
output: ['www.runoob.com', 'www.google.com', 'www.weibo.com']

json字符串

user_json = '{ "sites": [ { "name":"runoob" , "url":"www.runoob.com" }, { "name":"google" , "url":"www.google.com" }, { "name":"weibo" , "url":"www.weibo.com" } ] }'
r = jsonvalue.get(user_dict,'url')
print(r)
output: ['runoob', 'google', 'weibo']

当所取key在字符串包裹里时

user_json = { "sites": '[ { "name":"runoob" , "url":"www.runoob.com" }, { "name":"google" , "url":"www.google.com" }, { "name":"weibo" , "url":"www.weibo.com" } ]'}
r = jsonvalue.get(user_dict,'url')
print(r)
output: ['runoob', 'google', 'weibo']

当所取key在字符串包裹里时

user_dict = {"sites": "{ \"name\":\"google\" , \"url\":\"www.google.com\" }"}
r = jsonvalue.get(user_dict,'name')
print(r)
output: ['google']

key不存在时返回false

user_dict = {"sites": "{ \"name\":\"google\" , \"url\":\"www.google.com\" }"}
r = jsonvalue.get(user_dict, 'address')
print(r)
