用djoser实现密码重置

Question

我想使用djoser作为重置密码功能，并根据文档：

PASSWORD_RESET_CONFIRM_URL URL到您的前端密码重置页面。它应该包含{uid}和{token}占位符，例如#/password-reset/{uid}/{token}。您应该传递uid和token来重置密码确认端点。

我做了以下工作：

PASSWORD_RESET_CONFIRM_URL': 'reset/password/reset/confirm/{uid}/{token}',

url

url(r'^reset/password/reset/confirm/(?P<uid>[\w-]+)/(?P<token>[\w-]+)/$', PasswordResetView.as_view(),),

意见：

class PasswordResetView(APIView):

   def get (self, request, uid, token):
       post_data = {'uid': uid, 'token': token}
       return Response(post_data)

在我的邮件中，我得到了以下链接：http://127.0.0.1:8000/reset/password/reset/confirm/Mjk/538-954dccbc1b06171eff4d

很明显，我会得到：

{
"uid": "Mjk",
"token": "538-954dccbc1b06171eff4d"

}

但是当用户单击邮件中的链接时，我想转到auth/password/reset/confirm。

Answer 1

让我们先描述一下这些行动：

1. 用户单击该链接以重置密码。reset password
2. (在这里，您需要一个表单来获取用户名或电子邮件地址，这取决于您的设置)用户输入用户名并单击Submit。
3. 用户接收带有重置密码的链接的电子邮件。
4. 该链接打开浏览器，其中包含表单“创建新密码”。
5. 用户输入一个新密码并发送一个表单。
6. 浏览器将页面重定向到主页，并反馈密码已被重置。

然后，可以使用以下方法重置密码。

#template
<p>Use the form below to change your password. Your password cannot be the same as your username.</p>
<form role="form" method="post">
  {% csrf_token %}
  <input type="password" name="password1" placeholder="New Password">
  <input type="submit">
</form>

#view
from django.shortcuts import redirect, render
from djoser.conf import django_settings

def reset_user_password(request, uid, token):
    if request.POST:
        password = request.POST.get('password1')
        payload = {'uid': uid, 'token': token, 'new_password': password}

        url = '{0}://{1}{2}'.format(
            django_settings.PROTOCOL, django_settings.DOMAIN, reverse('password_reset_confirm'))

        response = requests.post(url, data=payload)
        if response.status_code == 204:
            # Give some feedback to the user. For instance:
            # https://docs.djangoproject.com/en/2.2/ref/contrib/messages/
            messages.success(request, 'Your password has been reset successfully!')
            return redirect('home')
        else:
            return Response(response.json())
    else:
        return render(request, 'templates/reset_password.html')

捕获错误、处理重定向和添加默认呈现程序类总是很重要的。在我的例子中，我最终使用了以下内容。

#view
import requests
from django.contrib import messages
from django.contrib.sites.models import Site
from django.http import HttpResponseRedirect
from django.shortcuts import render
from rest_framework.decorators import (api_view, permission_classes,
                                       renderer_classes)
from rest_framework.permissions import AllowAny
from rest_framework.renderers import JSONRenderer, TemplateHTMLRenderer

@api_view(('GET', 'POST'))
@renderer_classes((TemplateHTMLRenderer, JSONRenderer))
@permission_classes([AllowAny])
def reset_user_password(request, **kwargs):
    # uses djoser to reset password
    if request.POST:
        current_site = Site.objects.get_current()
        #names of the inputs in the password reset form
        password = request.POST.get('new_password')
        password_confirmation = request.POST.get('password_confirm')
        #data to accept. the uid and token is obtained as keyword arguments in the url
        payload = {
            'uid': kwargs.get('uid'),
            'token': kwargs.get('token'),
            'new_password': password,
            're_new_password': password_confirmation
        }

        djoser_password_reset_url = 'api/v1/auth/users/reset_password_confirm/'
        protocol = 'https'
        headers = {'content-Type': 'application/json'}
        if bool(request) and not request.is_secure():
            protocol = 'http'
        url = '{0}://{1}/{2}'.format(protocol, current_site,
                                     djoser_password_reset_url)
        response = requests.post(url,
                                 data=json.dumps(payload),
                                 headers=headers)

        if response.status_code == 204:
            # Give some feedback to the user.
            messages.success(request,
                             'Your password has been reset successfully!')
            return HttpResponseRedirect('/')
        else:
            response_object = response.json()
            response_object_keys = response_object.keys()
            #catch any errors
            for key in response_object_keys:
                decoded_string = response_object.get(key)[0].replace("'", "\'")
                messages.error(request, f'{decoded_string}')
            return HttpResponseRedirect(request.META.get('HTTP_REFERER'))
      # if the request method is a GET request, provide the template to show. in most cases, the password reset form.
      else:
        return render(request, 'account/password_reset_from_key.html')

由于API端点不需要任何身份验证，所以我添加了allowany权限。

以URL表示；

path('password/reset/<str:uid>/<str:token>/',
         reset_user_password,
         name='reset_user_password'),

最后，在主设置文件上，我更新了Djoser重置密码URL，使其与我正在构建的URL相匹配，以确保用户被重定向到我想要的页面。

DJOSER = {
"PASSWORD_RESET_CONFIRM_URL":
    "dashboard/auth/password/reset/{uid}/{token}/",
}
