Python基于Fernet实现加解密触发key格式错误问题求助

• 选择已有密钥的场景下，通过input()获取到的用户输入为字符串类型，Fernet实例化要求传入32位url安全的base64编码的字节类型数据，类型不匹配触发报错
• 解密场景下，输入的加密文本同样为字符串类型，decrypt()方法要求传入字节类型参数，也会触发同类类型错误

from cryptography.fernet import Fernet as dpsisbad

question1 = input("Do You Have A Key? (yes - y and no - n)\n")
if question1 == "y":
    key = input("Enter Your Key Here \n").encode("utf-8") # 输入字符串转字节
    print(key)
else:
    key = dpsisbad.generate_key() 
    print("Please Keep this Key Safely.\n")
    print(key)
dpsstalks = dpsisbad(key)
question2 = input("Do You Want to Encode Or Decode The Message? (Encode = e and Decode = d)\n")

if question2 == "e":
    gg = input("Enter the text you want to encode. \n")
    encoded_text = gg.encode()
    token = dpsstalks.encrypt(encoded_text)
    print(token)
else:
    text1 = input("Enter the the encrypted text. \n").encode("utf-8") # 加密文本字符串转字节
    token = dpsstalks.decrypt(text1)
    print(token.decode("utf-8")) # 解密结果转字符串输出更友好

• 输入已有密钥时需要完整复制生成的密钥内容，不要遗漏字符、添加多余空格或换行
• 输入加密文本时要完整粘贴加密后输出的字节内容，不要自行修改内容
