【问题描述】：

我正在尝试发送电子邮件验证码以确认帐户。

现在，问题是我想先给自己发一封电子邮件，然后再给我的另一封电子邮件。我已经关闭了我的防病毒软件，所以这应该不是问题。除此之外，我无法弄清楚我做错了什么，因为它没有在 gmail 帐户上发送电子邮件。请指出我做错了什么。我什至应用了this 线程提到的所有修复。

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'),
]

当我注册时，数据成功存储到数据库中（如预期的那样）。但它在代码的 view.py 中给出了 send_email(params) 错误。以下是错误：

【参考方案1】：

你错过了一点小事。 在settings.py

应该是EMAIL_HOST = 'smtp.gmail.com'

不是EMAIL_HOSTS = 'smtp.gmail.com'

【讨论】：

不敢相信这么愚蠢的错误让我哭了 3 个小时 XD 谢谢！！

【参考方案2】：

两件事：

一个，就像 Mohab 说的，应该是 EMAIL_HOST = 'smtp.gmail.com'，而不是 EMAIL_HOSTS = 'smtp.gmail.com'。修复它，它可能会起作用。

但如果这不起作用，则意味着 Google 正在阻止您的电子邮件地址被用于发送自动邮件。 You have to enable less secure apps in Gmail settings。不是最安全的选择，但没关系。注意：如果您长时间不发送自动电子邮件，Google 会自动关闭此设置。

如果这是问题所在，那么 Google 很可能会向您发送重要安全警报，其中包含与此答案中相同的说明。更多信息请查看this Stack Overflow post。
