Django Python - 由于目标机器主动拒绝，无法建立连接
Django Python - No connection could be made because the target machine actively refused it
我在 虚拟环境 的硬盘根目录下有一个 Django python 服务器。在命令行中，当我激活 env 和 运行 python manage.py 192.168.0.47:80 它正常启动服务器（没有迁移通知或任何东西），但是当我从浏览器加载页面时（使用 instancegaming.net 在本地，它在我的服务器主机文件中，过去在本地和远程都运行良好）它会永远加载和加载，当我转到 Django 服务器时 window 并执行 Ctrl+C 它会更新控制台并给我以下错误。请记住，此 env 是一个 全新安装 ，除 Django 外没有其他站点包。我之前在同一台服务器 (Windows 10 64-bit) 上成功拥有 运行 服务器，并且具有相同的路由器配置。
我看过其他帖子 像这样 (Python Django-Helpdesk Error: No connection could be made because the target machine actively refused it) 和一些其他帖子，但其中 none 似乎解决了问题.

每当我更新控制台日志（例如，按回车键或执行 Ctrl+C。）时，控制台错误永远循环出现。
当我去canyouseeme.org，在服务器运行ning的80端口上，它说它可以看到服务。此外，我在端口 :81 上有一个干净的 Apache 2 服务器 运行ning，它在本地和远程都可以正常工作。此外，当我 运行 一个 python 脚本来简单地检查端口 80 时，它会给出与上面相同的（简化的）错误。
端口检查器脚本：
import socket
s = socket.socket()
address = '127.0.0.1' # or 192.168.0.47
port = 80 # port number is a number, not string
try:
s.connect((address, port))
# originally, it was
# except Exception, e:
# but this syntax is not supported anymore.
except Exception as e:
print("something's wrong with %s:%d. Exception is %s" % (address, port, e))
finally:
s.close()
其中returns以下，
[WinError 10061] No connection could be made because the target machine actively refused it
最后，我尝试用 Django 做一个干净的 env 希望它能改变一些东西，但是，一个全新的开箱即用的副本给出了完全相同的错误。
我最终很轻松地解决了这个问题。我原本以为它与 socket 80 有关，但经过深思熟虑后，我转 DEBUG = True 发现我缺少主目录模板，以及指向未知页面的链接。对于出现此错误的任何人，如果可以，请尝试打开 DEBUG。
通过 python django --upgrade
重新安装 django
就我而言，我忘记设置电子邮件后端和身份验证。我通过将其添加到设置文件来解决它。
EMAIL_BACKEND = 'django.core.mail.backends.console.EmailBackend'
AUTHENTICATION_BACKENDS = (
# Needed to login by username in Django admin, regardless of `allauth`
"django.contrib.auth.backends.ModelBackend",
# `allauth` specific authentication methods, such as login by e-mail
"allauth.account.auth_backends.AuthenticationBackend",
)
就我而言，错误发生在我使用 django-allauth 且未配置电子邮件后端设置时。由于没有定义电子邮件后端，它使用 默认 SMTP 后端 试图向用户发送电子邮件。尽管没有 SMTP 设置，因此默认主机无法连接，因此我们收到此错误。这个上面的答案，这个人正在设置电子邮件后端的地方对我有用。虽然这个问题很普遍，但由于 allauth 包而不是 Django 或与服务器相关的问题本身，我遇到了错误。
你可以设置成console或者根据smtp。
EMAIL_BACKEND = 'django.core.mail.backends.console.EmailBackend'
AUTHENTICATION_BACKENDS = (
# Needed to login by username in Django admin, regardless of `allauth`
"django.contrib.auth.backends.ModelBackend",
# `allauth` specific authentication methods, such as login by e-mail
"allauth.account.auth_backends.AuthenticationBackend",
)
出现这种类型的错误，下面设置中没有设置，复制粘贴检查
EMAIL_BACKEND = 'django.core.mail.backends.console.EmailBackend'
是的，但更简单的方法是将其放入您的本地设置中：
EMAIL_BACKEND = 'django.core.mail.backends.console.EmailBackend'
然后所有电子邮件将打印在您的控制台中。

出现这种类型的错误，下面设置中没有设置，复制粘贴检查
EMAIL_BACKEND = 'django.core.mail.backends.console.EmailBackend'
是的，但更简单的方法是将其放入您的本地设置中：
EMAIL_BACKEND = 'django.core.mail.backends.console.EmailBackend'
然后所有电子邮件将打印在您的控制台中。
