Django Unicode解码错误

Question

我尝试实现 this 哈希器以便能够验证从 drupal 7 导入的用户。

所以我把散列器放在 settings.py 中，如下所示：

PASSWORD_HASHERS = (

'myproj.drupal_hasher.DrupalPasswordHasher', #drupal hasher

'django.contrib.auth.hashers.PBKDF2SHA1PasswordHasher',

'django.contrib.auth.hashers.BCryptPasswordHasher',
'django.contrib.auth.hashers.SHA1PasswordHasher',
'django.contrib.auth.hashers.MD5PasswordHasher',
'django.contrib.auth.hashers.CryptPasswordHasher',
 )

但是它不会对从 drupal 导入的用户进行身份验证，对于在 Django 中创建的用户，我得到：

'ascii' codec can't decode byte 0xcf in position 0: ordinal not in range(128)

引用如下：

Exception Type: UnicodeDecodeError at /auth/
Exception Value: 'ascii' codec can't decode byte 0xcf in position 0: ordinal not in range(128)

我尝试将 .decode('utf-8') 解码为 encoded_hash，但得到了相同的结果。

所有源和目标数据库表都转换为 utf8_unicode_ci。我添加了

#-*- coding: utf-8 -*-

在所有相关页面的顶部。

几天来我一直在解决这个问题，非常感谢您的帮助。

Answer 1

首先，将'drupal$'附加到导入的密码：

（因为 drupal 是默认的哈希器，用户 1 已经将 drupal$ 哈希到他的密码）

UPDATE djangodb.auth_user SET password=CONCAT('drupal$',password) where id<>1;

然后才发现要加

password = password.encode('ascii','ignore')

在 DrupalPasswordHasher class 中 'encode' 和 'verify' 方法的开头，因为我的应用程序中的密码被编码为 utf，但散列器需要 ascii。

这些简单的要点起到了作用。
