在Django中使用SMTP发送邮件

Question

在我的网站上，我想通过电子邮件使用SMTP重置我的密码，但当我发送密码更改请求时，出现了这个错误：

这是我的settings.py文件：

    EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'

    EMAIL_HOST = 'smtp.gmail.com'
    EMAIL_PORT = 587
    EMAIL_HOST_USER = 'expresstest177@gmail.com'
    EMAIL_HOST_PASSWORD = "ibuc pvmq fkgb acah"
    EMAIL_USE_TLS = True
    EMAIL_USE_SSL = False
    
    DEFAULT_FROM_EMAIL = EMAIL_HOST_USER
    SERVER_EMAIL = EMAIL_HOST_USER
    EMAIL_ADMIN = EMAIL_HOST_USER

如果需要的话，这是urls.py文件：

urlpatterns = [
    path('password-reset/', auth_views.PasswordResetView.as_view(
        template_name='main/password_reset_form.html',
        email_template_name='main/password_reset_email.html',
        success_url=reverse_lazy('user:password_reset_done')), name='password_reset'),   

    path('password-reset/done/', auth_views.PasswordResetDoneView.as_view(template_name='main/password_reset_done.html'), name='password_reset_done'),
    path('password-reset/confirm/<uidb64>/<token>/', auth_views.PasswordResetConfirmView.as_view(
        template_name='main/password_reset_confirm.html',
        success_url=reverse_lazy('user:password_reset_complete')), name='password_reset_confirm'),

    path('password-reset/complete/', auth_views.PasswordResetCompleteView.as_view(template_name='main/password_reset_complete.html'), name='password_reset_complete'),
]

可能是什么问题呢？
