Python代码实现获取文件
1 GitLab官网查询通过API操作获取raw文件
Repository files API | GitLab
curl --header PRIVATE-TOKEN: your_access_token https://gitlab.example.com/api/v4/projects/13083/repository/files/app%2Fmodels%2Fkey%2Erb/raw?refmain 2GitLab 创建TOKEN 3GitLab查看项目编号

3运行Python代码Windows11 Python环境为3.8 4GitLab查看项目更新了提交信息 5.GitLab更新库文件与运行流水线
1查看GitLab共享库 2新建流水线文件ui.gitlabutil.yaml 3复制raw格式 4在GitLab devops03-devops-env 环境库项目添加CI配置文件路径 5查看前端项目devops03-devops-ui 修改Dockerfile,注释本地CI流水线文件避免后续运行错误 6查看前端项目目录下的index.html文件 (7) GitLab共享库新建目录util及GitLabUtil.py文件用来封装python类 8GitLabUtil.py文件代码

1.Python获取GitLab指定仓库文件报错
1报错 2原因分析
函数名错误
3解决方法
修改函数名称。
修改前 修改后 2. K8S master节点运行Python代码报错
1报错 2原因分析
encoding不是有效的关键词。
3解决方法
去掉encoding。
修改前 修改后 成功 3. GitLabCI 运行流水线报错
1报错 2原因分析
行尾缺少双引号
3解决方法
添加双引号。
成功
