/login 处的 TypeError 字符串必须在散列之前进行编码

Question

我遇到这个 Django 项目的错误。我已经尝试了我能遇到的所有建议，但仍然无法正常工作。以下是来自网络的错误。

环境：

Request Method: POST
Request URL: http://127.0.0.1:8000/login

Django Version: 2.2
Python Version: 3.9.7

    Installed Applications:
    ['main',
     'django.contrib.admin',
     'django.contrib.auth',
     'django.contrib.contenttypes',
     'django.contrib.sessions',
     'django.contrib.messages',
     'django.contrib.staticfiles',
     'django_filters']
    Installed Middleware:
    ['django.middleware.security.SecurityMiddleware',
     'django.contrib.sessions.middleware.SessionMiddleware',
     'django.middleware.common.CommonMiddleware',
     'django.middleware.csrf.CsrfViewMiddleware',
     'django.contrib.auth.middleware.AuthenticationMiddleware',
     'django.contrib.messages.middleware.MessageMiddleware',
     'django.middleware.clickjacking.XFrameOptionsMiddleware']

  79.`raise TypeError("Strings must be encoded before hashing")`

Exception Type: TypeError at /login
Exception Value: Strings must be encoded before hashing

Answer 1

正如错误消息明确指出的那样，您必须先对密码进行编码。

在第 171 行的 main/views.py 中，您有

hashed = bcrypt.hashpw(request.POST['login_password'], bcrypt.gensalt())

您的 request.POST 数据是一个字符串，因此您应该将其编码为字节：

hashed = bcrypt.hashpw(request.POST['login_password'].encode(), bcrypt.gensalt())

你可以select其他编码（不是默认utf8）和.encode('ascii')（选择一个，以后不要更改，utf8可能是最好的选择一般而言）。
