我正在使用Djoser创建身份验证后端。我希望发生以下情况：

  1. 用户http://localhost:8000/auth/users/使用电子邮件、用户名、密码和 re_password 注册
  2. 用户在输入的电子邮件中收到一封激活电子邮件，其中包含用于激活其帐户的 URL。URL 的格式为：（<web url>/activate/{uid}/token例如http://localhost:8000/activate/Mg/apur8c-6100390a061c5ff081235193867f943a：）
  3. 单击该 URL 会向服务器发送一个 GET 请求，其中视图 ( UserActivationView) 接收提取的 uid 和令牌并将其自己的请求发送到<web url>/users/activation/{uid}/token( http://localhost:8000/users/activation/Mg/apur8c-6100390a061c5ff081235193867f943a)。并返回它从该请求中获得的响应作为其响应。
  4. 用户帐户被激活。

这是执行上述所有操作的代码：

# Djoser configuration in settings.py
DJOSER = {
    'LOGIN_FIELD': 'email',

    'PASSWORD_RESET_CONFIRM_URL': 'password-reset/{uid}/{token}',
    'USERNAME_RESET_CONFIRM_URL': 'username-reset/{uid}/{token}',

    'SEND_ACTIVATION_EMAIL': True,
    'ACTIVATION_URL': 'activate/{uid}/{token}',

    'SEND_CONFIRMATION_EMAIL': True,
    'PASSWORD_CHANGE_EMAIL_CONFIRMATION': True,
    'USERNAME_CHANGED_EMAIL_CONFIRMATION': True,

    'USER_CREATE_PASSWORD_RETYPE': True,
    'SET_PASSWORD_RETYPE': True,
}

# views.py in user app (users/views.py)
from rest_framework.views import APIView
from rest_framework.response import Response
import requests


class UserActivationView(APIView):
    def get(self, request, uid, token):
        protocol = "https://" if request.is_secure() else "http://"
        web_url = protocol + request.get_host()
        post_url = web_url + '/auth/users/activation/'
        post_data = {'uid': uid, "token": token}
        print(f"Sending request to {post_url} with {post_data}")
        result = requests.post(post_url, data=post_data)     # <<-- causes the server to hang
        return Response(result.text)

# users/urls.py
from django.urls import path, include
from .views import UserActivationView

app_name = "users"

urlpatterns = [
    path('auth/', include('djoser.urls')),
    path('auth/', include('djoser.urls.jwt')),
    path('activate/<str:uid>/<str:token>/',
         UserActivationView.as_view())
]

# MAIN project urls.py
from django.contrib import admin
from django.urls import include, path


urlpatterns = [
    path('admin/', admin.site.urls),
    path('chat/', include('frontend.urls')),
    path("chat/", include('backend.urls')),
    path('api/accounts/', include('backend.urls')),
    path('', include('users.urls'))

]

现在，问题出现在第 3 步（result = requests.post(post_url, data=post_data)在线）。当视图试图发送一个 post 请求时，服务器会挂起相当长的一段时间。CTRL在此期间，当我执行+时它甚至不会停止C。这是我得到的输出（我添加了评论）：

或者，如果我通过 Postman 或单独的 Python 脚本手动发送激活请求，则该请求可以正常工作并且用户被激活：

该问题似乎仅在从视图中向服务器发出请求时出现。我也尝试过result = requests.get('http://localhost:8000/chat')作为实验，它也导致服务器挂起，而result = requests.get('http://google.com')不会导致此类问题。

该视图的代码取自此处，答案下方的人也评论道：

我该如何解决这个问题？

我在用：

  • 蟒蛇：3.7.5
