python 自写常用函数

"""
将时间戳转换成时间
模块：import time
参数：timestamp   时间戳  
     format： '%Y-%m-%d %X'  年-月-日 小时：分：秒 （参考官方说明)
返回格式：format 指定的对应格式

#### 生成hmac
def genhmac(keys, msgs):

#获取xml节点值

#返回当前时间
def now():

#写日志文件

###输出json格式
import json

data = {}
data['ckey'] = 'adadsadsf'

print json.dumps(data)



###获取外部参数提交 key=键值
def RequestData(key):
    if request.method == 'POST':
        return request.form.get(key,'')
    elif request.method == 'GET':
        return request.args.get(key,'')
    else:
        return ''
