Nexus操作-下载go依赖

• 中国境内我们事通过goproxy代理来下载go依赖，
• 具体参考goproxy的官网信息：https://goproxy.cn/

• 脚本会按照go.sum 当中的依赖列表去下载所有版本的依赖到本地机器上，脚本如下：

#!/bin/bash
convert_to_exclamation() {
  local result=()
  for word in "${@}"; do
    if [[ "${word}" =~ ^[A-Z] ]]; then
      new_word="!$(echo "$word" | tr 'A-Z' 'a-z')"
    else
      new_word="$word"
    fi
    result+=("$new_word")
  done

  if [ ${#result[@]} -eq 1 ]; then
    path=(${result[@]// / })
    echo "${result[@]}"
  elif [ ${#result[@]} -eq 2 ]; then
    path=(${result[@]// / })
    echo "${path[0]}/${path[1]}"
  elif [ ${#result[@]} -eq 3 ]; then
    path=(${result[@]// / })
    echo "${path[0]}/${path[1]}/${path[2]}"
  elif [ ${#result[@]} -eq 4 ]; then
    path=(${result[@]// / })
    echo "${path[0]}/${path[1]}/${path[2]}/${path[3]}"
  elif [ ${#result[@]} -eq 5 ]; then
    path=(${result[@]// / })
    echo "${path[0]}/${path[1]}/${path[2]}/${path[3]}/${path[4]}"
  elif [ ${#result[@]} -eq 6 ]; then
      path=(${result[@]// / })
      echo "${path[0]}/${path[1]}/${path[2]}/${path[3]}/${path[4]}/${path[5]}"
  fi
}
