命令行终端开启代理

配置开关代理的 alias

# 针对的是 zsh shell
vim ~/.zshrc

# 添加开关代理的 alias
alias proxy='export all_proxy=socks5://127.0.0.1:7890'
alias unproxy='unset all_proxy'

# 激活配置
source ~/.zshrc

开启代理

使用 proxy 开启代理，执行 curl ipinfo.io 命令，可以看到切换到了国外 ip：

{
  "ip": "xxx.xxx.xxx.xxx",
  "hostname": "xxx-xxx-xxx-xxx.ip.linodeusercontent.com",
  "city": "Los Angeles",
  "region": "California",
  "country": "US",
  "loc": "xxx,xxx",
  "org": "AS63949 Akamai Connected Cloud",
  "postal": "90009",
  "timezone": "America/Los_Angeles",
  "readme": "https://ipinfo.io/missingauth"
}

关闭代理

使用 unproxy 关闭代理，执行 curl ipinfo.io 命令，可以看到切回到了国内 ip：

{
  "ip": "xxx.xxx.xxx.xxx",
  "city": "Nanjing",
  "region": "Jiangsu",
  "country": "CN",
  "loc": "xxx,xxx",
  "org": "AS4134 CHINANET-BACKBONE",
