“字节"对象没有属性“编码" [英] 'bytes' object has no attribute 'encode'

问题描述

在将每个文档插入集合之前，我正在尝试存储盐和哈希密码.但是在对盐和密码进行编码时，它显示以下错误:

I'm trying to store salt and hashed password before inserting each document into a collection. But on encoding the salt and password, it shows the following error:

 line 26, in before_insert
 document['salt'] = bcrypt.gensalt().encode('utf-8')

AttributeError: 'bytes' object has no attribute 'encode'

这是我的代码:

def before_insert(documents):
    for document in documents:
        document['salt'] = bcrypt.gensalt().encode('utf-8')
        password = document['password'].encode('utf-8')
        document['password'] = bcrypt.hashpw(password, document['salt'])

我在带有python 3.4的virtualenv中使用eve框架

推荐答案

您正在使用:

bcrypt.gensalt()

此方法似乎会生成一个字节对象.这些对象没有任何编码方法，因为它们仅适用于ASCII兼容数据.因此，您可以尝试不使用 .encode('utf-8')

This method seems to generate a bytes object. These objects do not have any encode methods as they only work with ASCII compatible data. So you can try without .encode('utf-8')

Python 3文档中的字节描述
