Python TypeError：在散列之前必须对Unicode对象进行编码什么是错误的？

我得到一个错误，TypeError：在散列之前必须对Unicode对象进行编码。 我写代码

        user = Data()
        passwd = request.data['password']

        md5 = hashlib.md5()
        md5.update(passwd)

        user.password = md5.hexdigest()
        print(user.password)

        user.save()

我在代码顶部添加了#coding:utf-8，但也出现了相同的错误。我的代码中有什么错误？我应该如何修复它？

错误告诉您需要执行的操作：将密码编码到bytestring

md5.update(passwd.encode('utf-8'))

注意，尽管你可能根本不应该这样做；如果要使用用户密码，请使用用户模型的

set\u password（）

方法

（请不要在脚本中随机添加编码声明；这只会影响文件中的文字字符。）

相关：。请注意，

#-*-编码：utf-8-*-

定义了源文件的编码，并且是，因为它默认为utf-8。使用md5作为密码哈希算法可能不是一个好主意。查看此问题以了解详细信息：
