這個問題已經在這里得到解答： How to encrypt JSON in python但是，我在使用加密模塊時遇到錯誤。raise TypeError("{} must be bytes".format(name))    TypeError: data must be bytes這是我的代碼：from cryptography.fernet import Fernetkey= b'F9tdtAlS5kqVL5_uxKCnOPailXUqKsJmxbHWGLv_H-c='with open('info.json', 'rb') as loader1:    params = json.load(loader1)if xyz(x, y)==True:        fernet = Fernet(key)        encrypted=fernet.encrypt(params)        print(encrypted)        with open('info.json', 'wb') as writer1:            json.dump(encrypted, writer1)                print("Operation was a success")else:     print("error")
