如何使用 WSL（适用于 Linux 的 Windows 子系统）访问 Django 服务器？

Question

I'm using Bash on Ubuntu on Windows 10 and installed django within a python virtual environment. I'm able to start the django server successfully, but when I type in " http://127.0.0.1:8000/ " in my windows 10 browser I don't get a response.

I've tried changing the port number to something else (eg. python3 manage.py runserver 127.0.0.1:7171) and I still get nothing.

I don't think it's a firewall issue, as WSL and the browser and all running on the same Windows 10 laptop. Do you know what the issue might be?

(env) $ python3 manage.py runserver

Answer 1

On your WSL terminal run:

python3 manage.py runserver 0.0.0.0:8080

Include your hostname as Allowed Host(Computer Name) in settings.py .

In your browser run: http://yourhostname:8080 .

Answer 2

When doing this myself a while back, I found there was no way to bind things running in WSL to localhost.

I did however have success when connecting via my hostname.

So, given the hostname GAMMAFLYER, do the following:

python3 manage.py runserver 0.0.0.0:8000

This allows external connections.

Then in your browser:

http://GAMMAFLYER:8000

I have the same issue and answer of @Shadow works for me well, ie I have ability to access http://HOSTNAME:8000 from windows after python manage.py runserver 0.0.0.0:8000 on WSL.

But there is a way to get it work usual way and access http://localhost:8000 on windows by disabling a VirtualBox network adapter for those who have VirtualBox installed on their Windows systems.

I have found that the IP address of my hostname on windows is the IP of VirtualBox Host-Only Ethernet Adapter :

(windows cmd):

ping -4 HOSTNAME

Pinging HOSTNAME [192.168.56.1] with 32 bytes of data:

ipconfig -all

Ethernet adapter VirtualBox Host-Only Network:

After I have disabled this adapter from Control Panel\\Network and Internet\\Network Connections and reran python manage.py runserver on WSL shell it worked well and I have ability to access http://localhost:8000 from windows.

I am currently running wsl2 on a windows 10 box. I ran into this issue when trying to setup a django project. I was able to get it working by running the following command, on powershell.

netsh interface portproxy reset

There were some config errors with my proxyport and the above command was able to fix those errors. So if you had wsl2 working at one point and now it's not working, run that command. However, if you just installed wsl2 then you need to add a proxy port in order to access the port locally : netsh interface portproxy add v4tov4 listenport=4000 listenaddress=0.0.0.0 connectport=4000 connectaddress=192.168.101.100

In this case I am exposing the 4000 port.
