我使用django通过gmail smtp发送邮件。然而，它只在部署前工作。在生产或部署过程中，不管你怎么称呼，当我尝试发送邮件时，它一直在加载，并且只显示 "服务器错误500"。
以下是我的部分内容 settings.py
EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_HOST = 'smtp.gmail.com'
EMAIL_PORT = 587
EMAIL_USE_TLS = True
EMAIL_HOST_USER = config['EMAIL_USER']
EMAIL_HOST_PASSWORD = config['EMAIL_PASS']
以下是 .../django_project/users/views.py
from django.shortcuts import render, redirect
from django.contrib import messages
from django.contrib.auth.decorators import login_required
from .forms import UserRegisterForm, UserUpdateForm, ProfileUpdateForm
def register(request):
if request.method == 'POST':
form = UserRegisterForm(request.POST)
if form.is_valid():
form.save()
username = form.cleaned_data.get('username')
messages.success(request, f'Your account has been created! You are now able to log in.')
return redirect('login')
else:
form = UserRegisterForm()
return render(request, 'users/register.html', {'form': form})
@login_required()
def profile(request):
if request.method == 'POST':
u_form = UserUpdateForm(request.POST, instance=request.user)
p_form = ProfileUpdateForm(request.POST,
request.FILES,
instance=request.user.profile)
if u_form.is_valid() and p_form.is_valid():
u_form.save()
p_form.save()
messages.success(request, f'Your account has been updated!')
return redirect('profile')
else:
u_form = UserUpdateForm(instance=request.user)
p_form = ProfileUpdateForm(instance=request.user.profile)
context = {
'u_form': u_form,
'p_form': p_form
}
return render(request, 'users/profile.html', context)
让人困惑的是，我的教程视频没有把任何从 django.core.mail import send_mail 或什么的。所以我不知道上面的view.py是不是应该显示的。
也许这个问题是Gmail本身的问题。请让我知道如何解决这个问题。谢谢。
我简单地设置了 DEBUG = True 并看到错误信息从 error.log.

我希望这篇日志能给大家一些说明，到底出了什么问题。有人能给我指出正确的方向吗？
谢谢Sachin。我按照建议进行了尝试，但我的服务器机器无法连接。相反，它显示这个消息。
(venv) myusername@hostname:~$ telnet smtp.gmail.com 587
Trying 2404:6800:4008:c00::6d...
Trying 108.177.97.109...
telnet: Unable to connect to remote host: Connection timed out
不幸的是，问题仍然存在。
经过一段时间，我意识到哪里出了问题。我使用 两步验证 我的Gmail账户，这意味着我的密码不能在外部程序中使用，比如django，除非我把它替换为 应用程序密码.
更多信息，请访问官方网页 应用程序密码:https:/support.google.comaccountsanswer185833?hl=en
而如果你使用的是linode的虚拟主机公司，他们可能会因为某些原因而屏蔽电子邮件端口，所以也可能是外部问题。
