DJANGO电子邮件确认：[WinError 10061]无法建立连接，因为目标计算机主动拒绝了它

如何解决DJANGO电子邮件确认：[WinError 10061]无法建立连接，因为目标计算机主动拒绝了它

我正在尝试发送电子邮件验证码以确认帐户。

现在，问题是我想先向自己发送一封电子邮件，然后再发送另一封电子邮件。我已经关闭了防病毒软件，所以这应该不是问题。除此之外，我无法弄清楚我们做错了什么，因为它没有通过gmail帐户发送电子邮件。请指出我做错了。我什至应用了this线程中提到的所有修补程序。

views.py

from django.core.mail import send_mail
from django.shortcuts import render,redirect
from django.contrib import messages,auth
from django.contrib.auth.models import User # this table already exists in django we import it 
from django.contrib.auth import authenticate,login
from django.conf import settings
from django.core.mail import EmailMessage

def register(request):
    if request.method=='POST':
        fname = request.POST['fname']
        lname=request.POST['lname'] #request.post[id of the input field]
        email = request.POST['email']
        password = request.POST['pass']
        password2 = request.POST['confirmpass']
        agree=request.POST.get('agree')
        if fname == '':
             messages.warning(request,'Please enter First name!')
             return redirect('register')

        if lname == '':
             messages.warning(request,'Please enter Last name!')
             return redirect('register')

        if email == '':
             messages.warning(request,'Please enter Email!')
             return redirect('register')

        if password == '':
             messages.warning(request,'Please enter Password!')
             return redirect('register')

        if password2 == '':
             messages.warning(request,'Please enter Confirm Password!')
             return redirect('register')
        if ('agree' not in request.POST):
             messages.warning(request,'Please agree to our terms and conditions!')
             return redirect('register')

        if password==password2:

            if User.objects.filter(username=email):
                messages.error(request,"Email Already Exists")
                return redirect('register')
            else:
                user=User.objects.create_user(username=email,first_name=fname,last_name=lname,password=password) #these are postgres first_name,last_name
                user.save()
                messages.success(request,"Successfully Registered")
                subject = 'Site Contact Form'
                contact_message = "%s : %s via %s "%(fname,lname,email)
                from_email = settings.EMAIL_HOST_USER
                to_email = [from_email,'[e-mail]']
                send_mail(subject,contact_message,from_email,to_email,fail_silently=False)
    
                return redirect('login')
        
        

        else:
            messages.error(request,"Passwords don't match")
            return redirect('register')
    else:
        return render(request,'signupdiv.html')

settings.py

EMAIL_HOSTS = 'smtp.gmail.com'
EMAIL_HOST_USER = '[e-mail]'
EMAIL_HOST_PASSWORD = '*****'
EMAIL_PORT = 587
EMAIL_USE_TLS = True
EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
DEFAULT_FROM_EMAIL = EMAIL_HOST_USER

urls.py

from django.urls import path
from . import views

urlpatterns = [
    path('login',views.login,name='login'),path('register',views.register,name='register'),path('logout',views.logout,name='logout'),]

注册后，数据成功存储到数据库中（如预期）。但是它从代码的view.py中给出send_email（params）的错误。错误如下：

解决方法

您错过了一些琐碎的事情。 在settings.py

中

应为EMAIL_HOST = 'smtp.gmail.com'

不是EMAIL_HOSTS = 'smtp.gmail.com'

,

两件事：

像Mohab所说的那样，应该是EMAIL_HOST = 'smtp.gmail.com'，而不是EMAIL_HOSTS = 'smtp.gmail.com'。解决该问题，它可能会起作用。

但是，如果这不起作用，则意味着Google阻止了您的电子邮件地址被用来发送自动邮件。 You have to enable less secure apps in Gmail settings。不是最安全的选择，但是没关系。注意：如果您很长一段时间不发送自动电子邮件，则Google会自动关闭此设置。

如果这是问题所在，那么Google很可能会按照此答案中的说明向您发送了严重安全警报。进一步检查this Stack Overflow post。
