准备工作：

1、安装python2.7.12，步骤略  下载链接（链接：https://pan.baidu.com/s/1OA7UxQl47rKTwy5CHuB5Dw 密码：jlt2）

2、配置好python环境变量，验证是否安装成功

3、下载pycrypto-2.6.win32-py2.7.exe，安装pycrypto

4、pip 安装pkcs7、binascii、base64

方法一

class AES_ENCRYPT():
    def __init__(self):
        self.key = AES_SECRET_KEY
        self.mode = AES.MODE_CBC #CBC模式
        self.iv = IV


    #加密函数
    def encrypt(self, text):
        encode = PKCS7Encoder()#PKCS7
        encode_text = encode.encode(text)#编码格式
        crypto = AES.new(self.key, self.mode,self.iv)
        crypto_text = crypto.encrypt(encode_text)
        print(base64.b64encode(crypto_text)) #转换base64编码
    #解密函数
    def unencrypt(self,text1):
       dencode1 = AES.new(self.key, self.mode, self.iv)
       aa=base64.b64decode(text1)
       bb=dencode1.decrypt(aa).decode('utf8')
       print bb


if __name__ == '__main__':
    aes_encrypt = AES_ENCRYPT()
    text = {"name":"zhangsan",
            "age":6}
    text1 = "go/qYTXY4P0Fq0m7rSdDFHPHTzh1wkO7U62ll2+PKWA="

    str=json.dumps(text)
    aes_encrypt.encrypt(str)
    aes_encrypt.unencrypt(text1)
