Django Python - 无法建立连接，因为目标计算机主动拒绝它

标签： python django port80 virtual-environment

我的硬盘根目录下的虚拟环境中有一个Django python服务器。在命令行中，当我激活env并运行python manage.py 192.168.0.47:80时，它启动服务器正常（没有迁移通知或任何内容），但是当我从浏览器加载页面时（使用instancegaming.net本地，这是我的服务器主机文件，并在过去本地和远程工作正常）它永远加载和加载，当我去Django服务器窗口并Ctrl+C它更新控制台并给我以下错误。请注意，此env是全新安装，除了Django之外没有其他网站包。我之前已经在同一台服务器（ Windows 10 64位）上使用相同的路由器配置成功运行了服务器。

我已经查看了其他帖子，如此（Python Django-Helpdesk Error: No connection could be made because the target machine actively refused it）和其他一些帖子，但这些都没有解决问题。

控制台窗口：

每次更新控制台日志时，控制台错误都会永久循环（例如，按Enter或执行Ctrl+C。）

当我访问 canyouseeme.org 时，在服务器运行时在端口80上显示它可以看到服务。另外，我在端口:81上运行了一个干净的Apache 2服务器，它在本地和远程都可以正常工作。另外，当我运行python脚本来简单地检查端口80时，它会给出与上面相同（简化）的错误。

端口检查程序脚本：

    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()

返回以下内容，

  

[WinError 10061]无法建立连接，因为目标计算机主动拒绝它

最后，我试图用Django做一个干净的env，希望它会改变一些东西，但是，一个新的，开箱即用的副本给出了完全相同的错误。

5 个答案:

答案 0 :(得分：2)

我最终很容易解决这个问题。我最初虽然它与套接字80有关，但在做了一些深思熟虑后，我转向DEBUG = True并发现我的主目录缺少模板，并链接到未知页面。对于出现此错误的任何人，如果可以，请尝试启用DEBUG。

答案 1 :(得分：0)

通过python django --upgrade重新安装django

答案 2 :(得分：0)

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中来解决它。

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",
)

答案 3 :(得分：0)

就我而言，错误发生在我使用 django-allauth 时未配置电子邮件后端设置。由于没有定义电子邮件后端，它使用了默认 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，我们收到了此错误。上面这个人设置电子邮件后端的答案对我有用。尽管这个问题很笼统，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。 您可以将其设置为控制台或根据 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",
)

答案 4 :(得分：0)

出现这种类型的错误没有设置在设置下面复制粘贴检查

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