项目里用到的python知识点

1 ini文件处理
创建ini文件
config = configparser.ConfigParser()
config.read(AUTH_STATUS_FILE)
config.add_section("authorization")
config.set("authorization", "file_status", "normal")    
config.set("authorization", "auth_status", "normal")
config.set("authorization", "remain_time", "100")
config.add_section("systime")
config.set("systime", "file_status", "normal")
config.set("systime", "time_status", "normal")
config.write(open(AUTH_STATUS_FILE, "w"))  
从字符串解析ini文件
config = configparser.ConfigParser(allow_no_value=True)
config.read_string(auth_info.decode())
auth_id = config.get('auth_id', 'id')
start_time = config.get('auth_date', 'start')
end_time = config.get('auth_date', 'end')

2 时间转换与比较
tStart = time.strptime(start_time, "%Y%m%d%H%M%S")
tEnd = time.strptime(end_time, "%Y%m%d%H%M%S")
dStart = datetime.datetime(* tStart[:6])
dEnd = datetime.datetime(* tEnd[:6])
dCurrent = datetime.datetime.now()

3 文件读写
with open(FACEMP_AUTH_OUT, 'r') as f:
    auth_crypt_info = f.read()
    
4 把python源码编译为pyc
py_compile.compile('./facemp_check.py')

5 生成rsa公私钥对
from M2Crypto import RSA,BIO
rsa = RSA.gen_key(1024, 3, lambda *agr:None)
rsa.save_pub_key('facemp_pub.key')
rsa.save_key('facemp_pri.key', None)

6 私钥加密
privkey = M2Crypto.RSA.load_key('facemp_pri.key')
encrypted = privkey.private_encrypt(message, M2Crypto.RSA.pkcs1_padding)

7 公钥解密
pubkey = M2Crypto.RSA.load_pub_key(FACEMP_PUB_KEY)
auth_info = pubkey.public_decrypt(auth_crypt_info, M2Crypto.RSA.pkcs1_padding)
