WSL2使用clash for windows代理

wsl_clash_proxy.sh

# WSL通过Win访问网络，所以WSL的网关指向的是Windows，DNS服务器指向的也是Windows，设置WSL的proxy为win的代理ip+端口即可
# WSL中的DNS server在/etc/resolv.conf中查看，该文件是由/etc/wsl.conf自动生成的。
# 如果关闭了wsl.conf中自动生成resolve.conf并自行修改了resolve.conf，DNS nameserver并不是本机win ip
# 需要开启wsl.conf的自动生成，再运行以下命令

# 添加到环境变量设置中，例如~/.zshrc
export hostip=$(cat /etc/resolv.conf |grep -oP '(?<=nameserver\ ).*')
export https_proxy="http://${hostip}:7890"
export http_proxy="http://${hostip}:7890"

我的问题比较奇怪，不知道有没有人有遇到过，直接用wsl2和clash的话，是可以访问外网的，但是使用apt-get update的时候，会一直卡在0%的进度，但是能ping通源的域名，单独关闭设置里的代理也不行，必须要把clash也关掉才能update成功。

If you are using the http_proxy variable, you need to check whether the http_proxy variable continues to be used after running sudo. Generally, sudo will clear the environment variables of the common user by default. Previously, I encountered this issue where sudo curl ip.gs could not use the proxy due to this reason. I eventually solved the issue by modifying the /etc/sudoers file using sudo visudo and adding Defaults env_keep += "http_proxy https_proxy ftp_proxy no_proxy", which allowed sudo to use the proxy correctly.

Works for me, thanks! It bothers me about 1 month.

我也碰到同样问题，最后发现在Docker-Desktop settings里配置proxy 127.0.0.1:7890就可以了

官方文档（看场景二）：https://learn.microsoft.com/zh-cn/windows/wsl/networking#identify-ip-address

按官方文档的说明，把获取 ip 地址的方式换一下

# 添加到环境变量设置中，例如~/.zshrc

export hostip=$(ip route show | grep -i default | awk '{ print $3}')
export https_proxy="http://${hostip}:7890"
export http_proxy="http://${hostip}:7890"
