# 针对web端json协议的通信库，通信协议为json,传出的data为json格式，接收的数据也是json格式
# 外界调用时可先初始化web_json类，如下所示：
# get调用
# web = web_json("http://baidu.com/")
# params = "abcd/select/100000?userID=1234&groupID=79"
# web.url_get(params)
# 
# post调用
# web = web_json("http://baidu.com/")
# params = "abcd/select/100000"
# data = '{"name": "jack", "id": "1"}'
# web.url_post(params, data)
