gitpython 操作 git 仓库

对模块的诸多功能进行一个封装
代码发布概述图

能够让你通过 python 代码操作 git 仓库

安装

pip3 install gitpython

基本使用

import os
from git.repo import Repo

# 下载远程仓库的代码可以怎么搞   clone  pull
# 先定义代码的存放位置
download_path = os.path.join('santa','NB')
Repo.clone_from('https://github.com/DominicJi/TeachTest.git',to_path=download_path,branch='master')

# ############## 2. pull最新代码 ##############
import os
from git.repo import Repo
 
local_path = os.path.join('santa', 'NB')
repo = Repo(local_path)
repo.git.pull()


# ############## 3. 获取所有分支 ##############
import os
from git.repo import Repo
 
local_path = os.path.join('santa', 'NB')
repo = Repo(local_path)
 
branches = repo.remote().refs
for item in branches:
    print(item.remote_head)
    
    
# ############## 4. 获取所有版本 ##############
import os
from git.repo import Repo
 
local_path = os.path.join('santa', 'NB')
repo = Repo(local_path)
 
for tag in repo.tags:
    print(tag.name)

    
# ############## 5. 获取所有commit ##############
import os
from git.repo import Repo
 
local_path = os.path.join('santa', 'NB')
repo = Repo(local_path)
 
# 将所有提交记录结果格式成json格式字符串 方便后续反序列化操作
commit_log = repo.git.log('--pretty={"commit":"%h","author":"%an","summary":"%s","date":"%cd"}', max_count=50,
                          date='format:%Y-%m-%d %H:%M')
log_list = commit_log.split("
")
real_log_list = [eval(item) for item in log_list]
print(real_log_list)
 
    
# ############## 6. 切换分支 ##############
import os
from git.repo import Repo
 
local_path = os.path.join('santa', 'NB')
repo = Repo(local_path)
 
before = repo.git.branch()
print(before)
repo.git.checkout('master')
after = repo.git.branch()
print(after)
repo.git.reset('--hard', '854ead2e82dc73b634cbd5afcf1414f5b30e94a8')
 
    
# ############## 7. 打包代码 ##############
with open(os.path.join('santa', 'NB.tar'), 'wb') as fp:
    repo.archive(fp)

ps:当服务器特别多的时候，从同一个地方下载数据回出现压力过大的情况(上传者只有一个，下载者有N多个，上传者压力太大)

如何解决这种问题???

比特流技术

将所有人都变成既可以是上传者也可以是下载者

联想你下载小片片的时候有些速度快游戏速度慢，速度快可能是因为你室友的电脑中就有，你是从你室友的电脑中下载的，速度慢是因为你的周围都没有该资源的提供者
