django 访问问题

Question

1.ubutu12.04 vagrant（虚拟机 -ubutu12.04） python2.7 django 1.10.3

2.安装已经完成。

root@precise32:python manage.py migrate

root@precise32:/usr/local/frist_django# python manage.py runserver 0.0.0.0:8000
Performing system checks...

Django version 1.10.3, using settings 'frist_django.settings'
Starting development server at http://0.0.0.0:8000/
Quit the server with CONTROL-C.

3.django已经启动，但是在访问的时候，只能出现问题。
1)只能使用127.0.0.1：8000 访问，使用localhost:8000和ip:8000都访问不成功
2）django放在虚拟机中，同网段的服务器在访问django时候也报错。

报错内容一般是：

Invalid HTTP_HOST header: '192.168.9.209:8000'. You may need to add u'192.168.9.209' to ALLOWED_HOSTS.
[28/Nov/2016 08:51:00] "GET / HTTP/1.1" 400 60610
Invalid HTTP_HOST header: '192.168.9.209:8000'. You may need to add u'192.168.9.209' to ALLOWED_HOSTS.

其中0.0.0.0:8000中的0.0.0.0 不是代表一切ip吗？

当前关于debug设置为：
DEBUG = True
ALLOWED_HOSTS = []

Answer 1

你可以设置ALLOWED_HOSTS = ['*'],但是强烈不推荐这么做。如果你的DEBUG设置为False，则必须设置ALLOWED_HOSTS. 在开发阶段可以设置DEBUG为True。查看文档发现

When DEBUG is True and ALLOWED_HOSTS is empty, the host is validated against ['localhost', '127.0.0.1', '[::1]'].

在DEBUG的也有相关描述

Finally, if DEBUG is False, you also need to properly set the ALLOWED_HOSTS setting. Failing to do so will result in all requests being returned as “Bad Request (400)”.

参考文档 https://docs.djangoproject.co...

Answer 2

问题解决：
修改django项目中settings.py文件：
DEBUG = True
ALLOWED_HOSTS = ['127.0.0.1','192.168.9.209','localhost'] ----> 可以访问网站的ip

具体详情参考：一楼的文档 ！ 谢谢大家

Answer 3

我一般会在 Vagrantfile 里这样配置网络

config.vm.network "private_network", ip: "192.168.33.10"

然后运行 python manage.py runserver 0.0.0.0:8000

最后访问 http://192.168.33.10:8000

我的 Vagrantfile 如下：

# -*- mode: ruby -*-
# vi: set ft=ruby :

Vagrant.configure(2) do |config|

  config.vm.box = "ubuntu/trusty64"

  config.vm.network "private_network", ip: "192.168.33.10"

  config.vm.provider "virtualbox" do |vb|
    vb.memory = "1024"
  end

end
