Strings must be encoded before hashing

Strings must be encoded before hashing

当我们将字符串传递给 hash 算法时，会出现 “TypeError: Strings must be encoded before hashing”。

解决错误，使用encode()

import hashlib, time


def get_token(username, token_id):
    timestamp = int(time.time())
    md5_format_str = "%s\n%s\n%s" % (username, timestamp, token_id)
    obj = hashlib.md5()
    obj.update(md5_format_str.encode())
    print("token format:[%s]" % md5_format_str)
    print("token :[%s]" % obj.hexdigest())
    return obj.hexdigest()[10:17], timestamp
