Python+gitlab實現分支批量合並打tag

　　最近公司代碼托管有SVN遷移到Gitlab，每次版本發布都要將代碼合並至master分支且打tag，應用較多重復且繁瑣，於是使用Python+gitlab實現分支批量合並打tag；

參考 python-gitlab文檔

環境准備：

1.Python3

2.pip install python-gitlab

token：gitlab用戶令牌，生成如下：

在gitlab用戶的setting--access token--填寫name+api+read_repository--create personal access token,會生成一個字符串

import gitlab, time


url = 'XXXXXXXXXX'　　　　# gitlab地址
token = 'XXXXXXXXXX'　　　　# gitlab用戶令牌

# 登錄
gl = gitlab.Gitlab(url, token)

dec_message = str(time.localtime().tm_year) + "年" + str(time.localtime().tm_mon) + "月" + str(
    time.localtime().tm_mday) + "日發布"


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

    def gitlab_merge(self, project_name, merge_tile):
        # 根據id獲得project對象
        project = gl.projects.get(app_dic[project_name])

        # 創建一個merge request
        try:
            mr = project.mergerequests.create({'source_branch': 'test',
                                               'target_branch': 'master',
                                               'title': merge_tile, })

            # 更新一個merge request 的描述
            mr.description = merge_tile
            mr.save()
            mr.merge()
