gitlab批量删除分支

一、概述

gitlab的java项目，运行几十年了，分支特别多。开发人员一般不会主动删除分支，长期下来，分支就特别多。

按照开发流程上来说，有新需求和bug，会开一个分支出来。等功能测试完成上线后，就会合并到master分支。

那么这些多余的分支就是没用的，需要删除。

二、批量删除分支

分支有几千个，通过gitlab页面，一个个手动删除，太耗费时间了，可以通过调用api接口来实现。

使用python代码来调用

这里会保留master分支，其他分支会被删除。如果需要保留指定分支，增加branch_list.remove('分支名')

# 注意，每次只能删除20个分支
import requests
from requests.auth import HTTPBasicAuth

# GitLab 实例 URL
gitlab_url = 'https://gitlab.qq.com'

# GitLab 用户名和密码
username = 'xiao'
password = 'abcd@1234'

# GitLab 项目 ID
project_id = '1969'

# 登录获取访问令牌
login_url = f'{gitlab_url}/oauth/token'
login_data = {
    'grant_type': 'password',
    'username': username,
    'password': password
}

response = requests.post(login_url, data=login_data)
if response.status_code == 200:
    access_token = response.json()['access_token']
    print("Successfully logged in and obtained access token.")
else:
    print(f"Failed to log in: {response.status_code}")
    print(response.json())
    exit()

# 获取项目的分支列表
branches_url = f'{gitlab_url}/api/v4/projects/{project_id}/repository/branches'
headers = {
    'Authorization': f'Bearer {access_token}'
}

response = requests.get(branches_url, headers=headers)
branch_list=[]
if response.status_code == 200:
    branches = response.json()
    # print("Remote branches:")
    for branch in branches:
        # print(branch['name'])
        branch_list.append(branch['name'])
else:
    print(f"Failed to retrieve branches: {response.status_code}")
    print(response.json())

try:
    # 移除master分支，不做删除
    branch_list.remove('master')
except Exception as e:
    print(e)
print("branch_list",branch_list)


for branch_name in branch_list:
    # 删除指定分支
    delete_branch_url = f'{gitlab_url}/api/v4/projects/{project_id}/repository/branches/{branch_name}'
    headers = {
        'Authorization': f'Bearer {access_token}'
    }

    response = requests.delete(delete_branch_url, headers=headers)
    if response.status_code == 204:
        print(f"Branch '{branch_name}' deleted successfully.")
    elif response.status_code == 404:
        print(f"Branch '{branch_name}' not found.")
    else:
        print(f"Failed to delete branch '{branch_name}': {response.status_code}")
        print(response.json())

注意事项：
修改变量gitlab_url ，username，password，改为实际的值。

project_id，这个是项目id，在gitlab上打开某个项目，就可以看到Project ID

 

每次执行，只能删除20个分支，因为api接口，一次只能返回20个。

 

二、批量删除tag

tag有几千个，通过gitlab页面，一个个手动删除，太耗费时间了，可以通过调用api接口来实现。

使用python代码来调用

这里会删除所有tag

'''
python 使用用户名和密码登录gitlab，删除git项目所有tag
'''
import requests

# GitLab 实例 URL
gitlab_url = 'https://gitlab.qq.com'

# GitLab 用户名和密码
username = 'xiao'
password = 'abcd@1234'

# GitLab 项目 ID
project_id = '1969'

# 登录获取访问令牌
login_url = f'{gitlab_url}/oauth/token'
login_data = {
    'grant_type': 'password',
    'username': username,
    'password': password
}

response = requests.post(login_url, data=login_data)
if response.status_code == 200:
    access_token = response.json()['access_token']
    print("Successfully logged in and obtained access token.")
else:
    print(f"Failed to log in: {response.status_code}")
    print(response.json())
    exit()

# 获取项目的所有标签
tags_url = f'{gitlab_url}/api/v4/projects/{project_id}/repository/tags'
headers = {
    'Authorization': f'Bearer {access_token}'
}

response = requests.get(tags_url, headers=headers)
if response.status_code == 200:
    tags = response.json()
    print("Remote tags:")
    for tag in tags:
        print(tag['name'])
else:
    print(f"Failed to retrieve tags: {response.status_code}")
    print(response.json())
    exit()

# 删除项目的所有标签
for tag in tags:
    tag_name = tag['name']
    delete_tag_url = f'{gitlab_url}/api/v4/projects/{project_id}/repository/tags/{tag_name}'
    response = requests.delete(delete_tag_url, headers=headers)
    if response.status_code == 204:
        print(f"Tag '{tag_name}' deleted successfully.")
    elif response.status_code == 404:
        print(f"Tag '{tag_name}' not found.")
    else:
        print(f"Failed to delete tag '{tag_name}': {response.status_code}")
        print(response.json())

注意事项：
修改变量gitlab_url ，username，password，改为实际的值。

project_id，这个是项目id，在gitlab上打开某个项目，就可以看到Project ID

每次执行，只能删除20个tag，因为api接口，一次只能返回20个。
