		return base64.b64encode(msg) #python3不太一样：因为3.x中字符都为unicode编码，而b64encode函数的参数为byte类型，所以必须先转码。
	def descypt(self,s):

print(type(s))
print(len(s))


s=eval(s)
print(type(s))
print(len(s))


s1=json.dumps(s);
print(type(s1))
print(len(s1))


obj=Crypt();
a=obj.encypt(s1)
print("输出加密后的密文：")
print(a)


b=obj.descypt(a)
#paramt=str(ret,'UTF-8').replace('\n','')
print("输出解密后的明文：")
print(b)

运行结果为：
