Python Base64转码解码

Python Base64 提供了好几种方法例如：

encode,

decode,

encodestring,

decodestring,

b64encode,

b64decode,

standard_b64encode

standard_b64decode

urlsafe_b64decode,

urlsafe_b64encode。

encode, decode

用来转码和 解码文件的,也可以对StringIO里的数据做编解码

#读取文件进行编码

inputRead = open('/Users/Mr_Chen/Desktop/test.jpeg','rb')
outputWrit = open('/Users/Mr_Chen/Desktop/testEncode.txt','wb')

#编码文件

base64Test = base64.encode(inputRead,outputWrit)

#读取文件后进行解码

inputRead = open('/Users/Mr_Chen/Desktop/testEncode.txt','rb')
outputWrit = open('/Users/Mr_Chen/Desktop/testDecode.jpeg','wb')

#解码文件

base64Test2 = base64.decode(inputRead,outputWrit)

encodestring, decodestring,

对字符串进行转码，解码

import base64
str1 = 'This is Test String'

#对字符串进行转码

enTest = base64.encodestring(str1)
print '转码后：',enTest

#对字符串进行解码

deTest = base64.decodestring(enTest)
print '解码后：',deTest

b64encode,b64decode,

（base64 模块提供了 b16encode,b16decode，b32encode,b32decode）

用来编码和解码字符串，并且有一个替换符号字符的功能。当base64编码后的字符除 了英文字母和数字外还有三个字符 + / =,用提替换到 +/= 这些字符

# -*- coding:utf-8 -*-

import  base64

#读取文件进行base16转码

inputRead = open('/Users/Mr_Chen/Desktop/test.txt','rb')
base16Test = base64.b16encode(inputRead.read())
inputRead.close()
print  'base16 Encode:',base16Test

#进行base16解码

base16Test2 = base64.b16decode(base16Test)
print 'base16 Decode:',base16Test2

#读取文件进行base32转码

inputRead2 = open('/Users/Mr_Chen/Desktop/test.txt','rb')
base32Test = base64.b32encode(inputRead2.read())
inputRead2.close()
print  'base32 Encode:',base32Test

#进行base32转码

base32Test2 = base64.b32decode(base32Test)
print 'base32 Decode:',base32Test2

#读取文件进行base64转码

inputRead3 = open('/Users/Mr_Chen/Desktop/test64.txt','rb')
base64Test = base64.b64encode(inputRead3.read())
inputRead3.close()
print  'base64 Encode:',base64Test

#进行base64解码

base64Test2 = base64.b64decode(base64Test)
print 'base64 Decode:',base64Test2

standard_b64encode，standard_b64decode

进行标准的base64,同样可以进行string ,文件的转码，解码

使用效果和encodestring 相同

# -*- coding:utf-8 -*-

import base64

text = 'This is Test String!'

#进行转码

baseStand = base64.standard_b64encode(text)
print 'baseStand:',baseStand

#进行解码

basee = base64.encodestring(text)
print 'baseEncodeString:',basee

urlsafe_b64decode,urlsafe_b64encode

主要进行对url 的安全转码

# -*- coding:utf-8 -*-

import  base64

text = "http://www.baidu.com"

#baseurl Encode 转码

baseUrl = base64.urlsafe_b64encode(text)
print "baseUrlEncode:" ,baseUrl

#baseurl Encode 解码

baseUrl2 = base64.urlsafe_b64decode(baseUrl)
print "baseUrlDecode:" ,baseUrl2
