前言

• 参考 https://www.jianshu.com/p/b3d4e5cee835

• 适用于git私服拉取个人所涉及权限的代码，方便有多个项目权限的人快速拉取自己所有权限的代码。

• 默认生成目录结构与gitlab一致

步骤一:获取权限你的代码权限文件d

从gitlab私服生成所有你有权限的代码信息

请求地址：

http://gitlab.dstcar.com//api/v4/projects?simple=true&per_page=100&page=1

postman方式获取

cookies自己登录gitlab生成

gitlab限制每次只能拉100条数据，超过100条自己分页处理

获取cookies

 添加cookies

请求成功后保存json文件到指定地方(步骤二会用到) eg:放到D:\\gitlab_projects.json

 

步骤二:执行java代码

以下根据个人所需修改对应代码，一般只需要修改下载fileName和srcDir参数

• 备注:有现成springboot项目你直接生成一个单元测试文件执行执行main方法,没有的话自己新建一个项目执行

              return null;
          }
      }
  }

  实际效果为下来所有你有权限的代码并且尝试切换develop环境（你想尝试换其他环境也可以自行修改代码参数）

  目录结构跟gitlab一致
