终端设置代理命令之前文章有写过的，趁今天重装了系统完善一下。

我的 Shell 使用 zsh，在 ~/.zshrc 下追加，如果使用 bash 需要修改 ~/.bashrc，可以使用 echo $SHELL 查看当前正在使用的 Shell。

命令用到了 jq 命令，需要先安装 brew install jq，其他平台替换为 yum 或者 apt-get。

# 获取内网 IP
getlocalip() {
  local_ip=$(ifconfig | grep 'inet ' | grep -v 127.0.0.1 | awk '{printf("%s / %s; ", $2, $6)}')

  if [ ! "${local_ip}" ]; then
    echo "Your are offline."
  else
    echo "${local_ip}"
  fi
}

# 获取外网 IP
getpublicip() {
  response=$(curl 'https://api.ip.sb/geoip' -Lsk -A Mozilla)
  if [ ! "${response}" ]; then
    echo "You are offline."
  else
    ip=$(echo $response | jq -r '.ip')
    country=$(echo $response | jq -r '.country')
    country_code=$(echo $response | jq -r '.country_code')
    city=$(echo $response | jq -r '.city')
    isp=$(echo $response | jq -r '.isp')
    echo "${ip} at ${city} in ${country}(${country_code}) / ${isp}"
  fi
}

# 获取 内外网 IP
getip() {
  echo "Local IP: $(getlocalip)"
  echo "Public IP: $(getpublicip)"
}

# 定义代理地址
export PROXY_URL=127.0.0.1:7890

# 开启代理
proxyon() {
  export https_proxy=http://${PROXY_URL};
  export http_proxy=http://${PROXY_URL};
  export all_proxy=socks5://${PROXY_URL};
  export no_proxy=localhost,127.0.0.1,*.local,*.vanke.com,*.vankeservice.com
  getip
}

# 关闭代理
proxyoff() {
  unset https_proxy http_proxy all_proxy no_proxy;
  getip
}

然后 source ~/.zshrc，就可以使用命令了。
