python 字符串转json

python中字符串怎么转json呢？不知道的小伙伴来看看小编今天的分享吧!

python中字符串怎么转json方法：

python字符串转json对象，需要使用json模块的loads函数

# encoding: utf-8

print "str转json"

import json

string_a = '{"accessToken": "521de21161b23988173e6f7f48f9ee96e28", "User-Agent": "Apache-HttpClient/4.5.2 (Java/1.8.0_131)"}'

print "type(string_a): ", type(string_a)

dict_a = json.loads(string_a)  # json_str == dict

print "dict_a: ", dict_a

print "type(dict_a): ", type(dict_a)

输出结果：

str转json

type(string_a):  <type 'str'>

dict_a:  {u'accessToken': u'521de21161b23988173e6f7f48f9ee96e28', u'User-Agent': u'Apache-HttpClient/4.5.2 (Java/1.8.0_131)'}

type(dict_a):  <type 'dict'>

import json

json_b = {"accessToken": "521de21161b23988173e6f7f48f9ee96e28", "User-Agent": "Apache-HttpClient/4.5.2 (Java/1.8.0_131)"}

print "type(json_b): ", type(json_b)

str_b = json.dumps(json_b)

print "str_b: ", str_b

print "type(str_b): ", type(str_b)

输出结果：

json转str

type(json_b):  <type 'dict'>

str_b:  {"accessToken": "521de21161b23988173e6f7f48f9ee96e28", "User-Agent": "Apache-HttpClient/4.5.2 (Java/1.8.0_131)"}

type(str_b):  <type 'str'>
