Question

我收到错误，TypeError：必须在散列之前对Unicode对象进行编码。我写了代码，

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

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

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

        user.save()

Traceback说

    md5.update(passwd)

我在代码顶部添加了#coding：utf-8，但发生了同样的错误。我的代码出了什么问题？我应该如何解决这个问题？

Answer 1

错误告诉您需要执行的操作：将密码编码为字节字符串。

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_password()方法。

（请不要随意向您的脚本添加编码声明;这只会影响文件中的文字字符。）

TypeError：在散列之前必须对Unicode对象进行编码有什么问题？
