Python+gitlab实现分支批量合并打tag

　　最近公司代码托管有SVN迁移到Gitlab，每次版本发布都要将代码合并至master分支且打tag，应用较多重复且繁琐，于是使用Python+gitlab实现分支批量合并打tag；

参考 python-gitlab文档

环境准备：

1.Python3

2.pip install python-gitlab

token：gitlab用户令牌，生成如下：

在gitlab用户的setting--access token--填写name+api+read_repository--create personal access token,会生成一个字符串

import gitlab, time


url = 'XXXXXXXXXX'　　　　# gitlab地址
token = 'XXXXXXXXXX'　　　　# gitlab用户令牌

# 登录
gl = gitlab.Gitlab(url, token)

dec_message = str(time.localtime().tm_year) + "年" + str(time.localtime().tm_mon) + "月" + str(
    time.localtime().tm_mday) + "日发布"


class gitlab_operation(object):
    
    def __init__(self):
        self.merge_tag = False

    def gitlab_merge(self, project_name, merge_tile):
        # 根据id获得project对象
        project = gl.projects.get(app_dic[project_name])

        # 创建一个merge request
        try:
            mr = project.mergerequests.create({'source_branch': 'test',
                                               'target_branch': 'master',
                                               'title': merge_tile, })

            # 更新一个merge request 的描述
            mr.description = merge_tile
            mr.save()
            mr.merge()
        except Exception as e:
            print(project_name + "出现错误，错误如下：\n" + str(e))
            self.merge_tag = False
        else:
            print(project_name + "合并成功，合并标题为：" + merge_tile)
            self.merge_tag = True
        # 1表示合并成功，可以后续打tag，0则表示合并失败，后续不打tag
        return self.merge_tag

    def gitlab_tag(self, project_name, tag_description):
        project = gl.projects.get(app_dic[project_name])
        tags = project.tags.list()

        # 如果有历史tag
        if tags:
            last_tag_name = tags[0].attributes["name"]

            # 最后需要加1
            version_num = int(last_tag_name[18:20]) + 1
            # 拼接，满足 tag_202008010_V1.0.01 格式
            new_tag_name = "tag_" + time.strftime("%Y%m%d") + "_V1.0." + "{0:0>2}".format(version_num)
            tag = project.tags.create({'tag_name': new_tag_name, 'ref': 'master'})
            tag.set_release_description(tag_description)
            print(project_name + "打tag成功" + new_tag_name)

        # 如果第一次打tag
        else:
            new_tag_name = "tag_" + time.strftime("%Y%m%d") + "_V1.0.01"
            tag = project.tags.create({'tag_name': new_tag_name, 'ref': 'master'})
            tag.set_release_description(tag_description)
            print(project_name + "打tag成功" + new_tag_name)


if __name__ == "__main__":
    # git工程格式为"app_name":app_dic[project_name] ，
    app_dic = {

        "app_name":app_id,
        ...
    }
    gitlab_handle = gitlab_operation()
    for i, j in app_dic.items():
        print("开始处理" + i + str(j) + "项目")
        if gitlab_handle.gitlab_merge(i, dec_message):
            gitlab_handle.gitlab_tag(i, dec_message)
        else:
            print(i + "合并失败，请手动打tag")
