JSON和Python加密:TypeError:字节类型的对象不可JSON序列化

Question

我做错了什么？我试图加密用户名和密码，但当我将它们放入json时，我会收到这个错误。欢迎任何帮助！很抱歉给您带来麻烦！Python 3.7.0我不知道加密版本。

def editjson(location, value):
with open("config.json") as f:
data = f.read()
d = json.loads(data)
d[location] = [value]
with open("config.json", 'w') as f:
f.write(json.dumps(d))
def firstruntrue():
key = Fernet.generate_key()
f = Fernet(key)
userog = input("What is your Username? ").encode()
encrypteduser = f.encrypt(userog).decode()
passwordog = input("What is your Password? ").encode()
encryptedpassword = f.encrypt(passwordog).decode()
editjson("firstrun", "False")
editjson("user", encrypteduser)
editjson("password", encryptedpassword)
editjson("key", key)
with open("./config.json", "r") as handler:
info = json.load(handler)
user = info["user"]
password = info["password"]
firstrun = info["firstrun"]

C:UsersUSERDesktopCode>python -u C:UsersUSERDesktopCodeOpenGradebook.py
What is your Username? test
What is your Password? test

TypeError: Object of type bytes is not JSON serializable

来自密码学文档：

key以字节为单位，并且您正在序列化字节对象editjson("key", key)。

尝试更改为editjson("key", key.decode())
