How to Use a Go Tool to Clone GitLab Projects via Token

First, request a personal access token from GitLab; this token grants access to all authorized groups and projects.

Next, download the Go tool from https://gitee.com/whoamiy/golang-git-tools . Modify the default values in main.go (GitLab host, token, and download directory) or pass them as command‑line arguments, then compile the program into a binary for script use.

The tool will iterate through all groups, retrieve project information via the GitLab API, and clone each repository to the specified local path using the provided token for authentication.

package main

import (
  "encoding/json"
  "flag"
  "fmt"
  "github.com/go-git/go-git/v5"
  githttp "github.com/go-git/go-git/v5/plumbing/transport/http"
  "io"
  "net/http"
  "os"
  "strconv"
  "strings"
)

var (
  gitlab_host  string
  gitlab_token string
  code_path    string
)

func init() {
  flag.StringVar(&gitlab_host, "host", "https://git.renzhikeji.com", "gitlab_host 请设置")
  flag.StringVar(&gitlab_token, "token", "eJAfTmyyyVYxxxtH5jsse", "gitlab_token 请设置")
  flag.StringVar(&code_path, "path", "/Users/renzhikeji/logs", "path 代码下载路径请设置")
}

func main() {
  flag.Parse()

  groups, err := allGroups()
  if err != nil {
    panic(err)
  }

  for _, group := range groups {
    marshal, _ := json.Marshal(&group)
    Info("=========项目组信息=================")
    fmt.Printf("%s", marshal)
    fmt.Println()
  }

  Info("=========项目信息收集中，请稍等=================")
  allProjectInfos, err := allProjectInfo(groups)
  if err != nil {
    panic(err)
  }

  Info("=========项目信息=================")
  Info("项目总数: ", len(allProjectInfos))

  for _, info := range allProjectInfos {
    dir := strings.Join([]string{code_path, info.Name}, "/")
    Info("git clone %s   %s  ......................", info.HTTPURLToRepo, dir)
    _, err := git.PlainClone(dir, false, &git.CloneOptions{
      Auth: &githttp.BasicAuth{Username: "abc123", Password: gitlab_token},
      URL:  info.HTTPURLToRepo,
      Progress: os.Stdout,
    })
    Error(err)
  }
}

The source code defines data structures for GitLab groups and projects, functions to request group and project lists via HTTP, and utility functions for logging and error handling.
