Python 解码Base64 得到码流格式文本实例

我就废话不多说了，直接上代码吧！#coding:utf8importbase64defBaseToFlow():whileTrue:str=input("Pleaseinput

我就废话不多说了，直接上代码吧！

# coding:utf8
import base64
 
 
def BaseToFlow():
 while True:
 str = input("Please input src: ")
 flag = input("Please input Decode - 1 or Encode - 2: ")
 if str == "":
 str = "ApIAGBcEAAAEBO6x3nLykEEhjWMX1wHs"
 if flag == "":
 flag = "1"
 if flag == "1":
 print("Decoding ...")
 dst = base64.b64decode(str)
 # print(type(dst))
 # <class 'bytes'>
 # print(dst)
 # b'\x02\x92\x00\x18\x17\x04\x00\x00\x04\x04\xee\xb1\xder\xf2\x90A!\x8dc\x17\xd7\x01\xec'
 # print(dst.hex()) --去掉\0x前缀 得到一个字符串
 # 02920018170400000404eeb1de72f29041218d6317d701ec
 HexFormat(dst.hex())
 elif flag == "2":
 print("Encoding ...")
 dst = base64.b64encode(str)
 print(dst)
 
 
def HexFormat(str):
 """
 :param str: 16进制连续字符串
 :return: 码流格式的16进制串
 """
 i = 1
 str2 = ""
 while (i <= len(str)):
 str2 = str2 + str[i - 1] + str[i] + " "
 if (i + 1) %16 == 0 and (i + 1) % 32 != 0:
 str2 = str2 + " "
 elif (i + 1) %32 == 0:
 str2 = str2 + "\n"
 i = i + 2
 
 
if __name__ == '__main__':
 BaseToFlow()

结果：

Please input src: 
Please input Decode - 1 or Encode - 2: 
Decoding ...
