WSL2中使用网络代理配置

背景

最近电脑升级了windows11且卸载了ubuntu系统，家里开发环境就顺带移步到WSL2。之前就听说wsl2的整体网络设计不同于wsl1非常麻烦，一直在逃避搞代理这回事儿。现在由于npm publish速度实在堪忧，设置代理这关是逃不掉了，前后折腾了2个小时总算搞明白了。在此记录。

过程

1. 关闭自动更新dns nameserver

#/etc/wsl.conf
[network]
generateResolvConf = false

2. 添加以下脚本至.bashrc或.zshrc

# add for proxy
export hostip=$(ip route | grep default | awk '{print $3}')
export hostport=1011#根据代理IP自行填入
alias proxy='
    export HTTPS_PROXY="http://${hostip}:${hostport}";
    export HTTP_PROXY="http://${hostip}:${hostport}";
    export ALL_PROXY="http://${hostip}:${hostport}";
    echo -e "Acquire::http::Proxy \"http://${hostip}:${hostport}\";" | sudo tee -a /etc/apt/apt.conf.d/proxy.conf > /dev/null;
    echo -e "Acquire::https::Proxy \"http://${hostip}:${hostport}\";" | sudo tee -a /etc/apt/apt.conf.d/proxy.conf > /dev/null;
'
alias unproxy='
    unset HTTPS_PROXY;
    unset HTTP_PROXY;
    unset ALL_PROXY;
    sudo sed -i -e '/Acquire::http::Proxy/d' /etc/apt/apt.conf.d/proxy.conf;
    sudo sed -i -e '/Acquire::https::Proxy/d' /etc/apt/apt.conf.d/proxy.conf;

3. 执行proxy设置代理

4. 每次重启wsl后, /etc/resolv.conf中的内容会被重置，所以需要执行以下内容：

#https://github.com/microsoft/WSL/issues/5420#issuecomment-646479747
sudo rm /etc/resolv.conf
sudo bash -c 'echo "nameserver 8.8.8.8" > /etc/resolv.conf'
sudo bash -c 'echo "[network]" > /etc/wsl.conf'
sudo bash -c 'echo "generateResolvConf = false" >> /etc/wsl.conf'
sudo chattr +i /etc/resolv.conf

5. 为代理软件设置防火墙放行
   win11下通过防火墙和网络保护 - 允许应用通过防火墙，将v2ray（根据个人情况而定，我用得是v2ray）设置为放行
   
   

6. v2ray设置允许局域网访问
   

7. 使用curl测试是否成功

curl -vv google.com

Troubleshooting

1. 占位程序接收到错误数据 - 管理员权限下执行netsh winsock reset 重启电脑解决。
