Why is Django throwing error "DisallowedHost at /"?
提问by alukin
I am setting up my own Django server using this Digital Ocean tutorial. I created the Django framework following each step, and ran the server using this command:
我正在使用这个Digital Ocean 教程设置我自己的 Django 服务器。我按照每个步骤创建了 Django 框架，并使用以下命令运行服务器：
./manage.py runserver 0.0.0.0:8000
When I tried to visit the IP at port 8000, the following error was shown:
当我尝试访问 8000 端口的 IP 时，显示以下错误：
DisallowedHost at /
Invalid HTTP_HOST header: 'XXX.XXX.XXX.XXX:8000'. You may need to add u'XXX.XXX.XXX.XXX' to ALLOWED_HOSTS.
(IP substituted with X's)
（IP 替换为 X）
Why is this happening?
为什么会这样？

In your settings.py, there is a list called ALLOWED_HOSTS. You need to add the IP address you see in the error to that list:
在您的 中settings.py，有一个名为ALLOWED_HOSTS. 您需要将您在错误中看到的 IP 地址添加到该列表中：
ALLOWED_HOSTS = ['XX.XX.XX.XX']
ALLOWED_HOSTS = ['XX.XX.XX.XX']
The port should not be added.
不应添加端口。
Explanation:
解释：
Django checks the Hostheader of the HTTP request for a url/ip address that is within the allowed hosts.
Django 会检查HostHTTP 请求的标头，以查找允许主机内的 url/ip 地址。
From the django website:
从 Django 网站：
This is a security measure to prevent HTTP Host header attacks, which are possible even under many seemingly-safe web server configurations.
这是一种防止 HTTP Host 标头攻击的安全措施，即使在许多看似安全的 Web 服务器配置下也是可能的。

For Run Django Project on localhost with free hosting by "ngrok"
用于通过“ngrok”免费托管在本地主机上运行 Django 项目
run ngrok http 8000
运行 ngrok http 8000
(before run this in your project make sure your project are required to run on localhost like- python manage.py runserver)
（在您的项目中运行之前，请确保您的项目需要在 localhost 上运行，例如 python manage.py runserver）
http://563ae936.ngrok.io-> http://localhost:8000
http://563ae936.ngrok.io-> http://localhost:8000
Edit Setting.py
编辑设置.py
ALLOWED_HOSTS = ['563ae936.ngrok.io', 'localhost', '127.0.0.1', 'testserver']
ALLOWED_HOSTS = ['563ae936.ngrok.io', 'localhost', '127.0.0.1', 'testserver']
Here "563ae936.ngrok.io" Replace your Host name with removing http://or https://
这里“563ae936.ngrok.io”用删除http://或https://替换您的主机名

Include both ('www.name.com', 'ip.ip.ip.ip') Set Debug = True, then retry the IP & URL Address.
包括两者 ('www.name.com', 'ip.ip.ip.ip') 设置 Debug = True，然后重试 IP 和 URL 地址。
Go to the Traceback section, find the message [ raise DisallowedHost(msg) ] click -> ▼ Local vars
转到 Traceback 部分，找到消息 [ raise DisallowedHost(msg) ] 单击 -> ▼ Local vars
It will show the incoming domain name and the settings for allowed hosts:
它将显示传入的域名和允许主机的设置：
*Variable Value
*allowed_hosts ['ip.ip.ip.ip', 'name.com']
*domain 'something.com'
*
Copy the incoming value into your settings.py. If the you see old settings restart the server\nginx
将传入值复制到 settings.py 中。如果您看到旧设置，请重新启动服务器\nginx
