在python编程中经常用到json库来对json串进行解码和编码解析，现将之间的转换整理如下：
json.dumps
将python对象编码成json字符串, 返回json串json.loads
将已编码的json串解码为python对象，返回python对应的数据类型
代码
#-*- coding:utf-8 -*-
#__author__='yy'
import json
if __name__=="__main__":
'''
print("json转dict")
json_str='{"name":"开源优测","url":"www.testingunion","id":"DeepTest"}'
#原类型
print("原类型：",type(json_str))
#转换成dict对象
json_dict = json.loads(json_str)
print("转换后的类型:",type(json_dict))
#遍历
for(k,v) in json_dict.items():
print(k,":",v)
print("字典型转json串")
json_dict = {
"name":"开源优测",
"url":"www.testingunion.com",
"id":"DeepTest"
}
print("原类型：",type(json_dict))
json_str = json.dumps(json_dict)
print("转换后类型：",type(json_str))
print(json_str)
'''
print("json串解析实例")
json_demo = """ #用单引号，双引号，三引号引起来的就是字符串

#将json串转换成字典
json_dict = json.loads(json_demo)
#遍历字典
for (k, v) in json_dict.items():
