批量下载GitHub代码

华为被特朗普政府针对，连GitHub、Apache都瑟瑟发抖。

为了保存GitHub上开源项目，批量下载GitHub代码如下

1、第一个代码，用于获取目标对象所有开源项目网址

import requests

def getProject(url):
    response = requests.get(url)
    content = response.text
    content_ul = content.split('<div class="org-repos repo-list">')[1]
    content_li = content_ul.split('<ul>')[1].split('</ul>')[0]
    projects = content_li.split('<h3 class="wb-break-all">')[1:]
    page_info = []
    for project in projects:
        project_info = []
        
        project_name = project.split('>')[1].split('<')[0].strip()
        project_url = 'https://github.com' + project.split('href="')[1].split('"')[0].strip()
        project_info.append(project_name)
        project_info.append(project_url)
        
        try:
            project_language = project.split('"programmingLanguage">')[1].split('<')[0].strip()
            project_info.append(project_language)
        except:
            project_language = 'None'
            project_info.append(project_language)
            
        try:
            project_star = project.split('stargazers')[1].split('</span>')[1].split('</a>')[0].strip()
            project_info.append(project_star)
        except:
            project_star = 'None'
            project_info.append(project_star)
        
        try:
            project_memb = project.split('members')[1].split('</span>')[1].split('</a>')[0].strip()
            project_info.append(project_memb)
        except:
            project_memb = 'None'
            project_info.append(project_memb)
        
        page_info.append(project_info)
    return page_info

fp = open('GitHub-google.txt', 'w+')
# 生成一个txt文件，存贮五个变量：项目名，项目网址，项目脚本语言，项目加星情况，项目共享数
fp.write('project_name\tproject_url\tproject_language\tproject_star\tproject_memb\n')
for page in range(41,51):
    # 此处更改为你目标对象，我先下载了google公司贡献的1774条开源项目
    url = 'https://github.com/google?page=' + str(page)
    page_info = getProject(url)
    for li in page_info:
        fp.write(li[0]+'\t')
        fp.write(li[1]+'\t')
        fp.write(li[2]+'\t')
        fp.write(li[3]+'\t')
        fp.write(li[4]+'\n')
    print(page, 'Done!')
fp.close()

2、将上述代码获取得到的txt用excel打开，我按加星情况降序下载的。复制上述项目网址，成为一个新的txt文件。txt文件内仅包含项目网址，如下所示：

https://github.com/google/physical-web
https://github.com/google/lovefield
https://github.com/google/blockly
https://github.com/google/go-cloud
https://github.com/google/android-classyshark
https://github.com/google/j2objc
https://github.com/google/flutter-desktop-embedding
https://github.com/google/closure-compiler
https://github.com/google/seesaw
https://github.com/google/seq2seq
https://github.com/google/error-prone
......

利用以下代码批量下载开源代码：

    content = response.text
    btn = content.split('btn btn-outline get-repo-btn js-anon-download-zip-link ')[1]
    zip_url = 'https://github.com' + btn.split('href="')[1].split('"')[0].strip()
    
    try:
        request.urlretrieve(zip_url, save_path + file_name + '.zip')
    except:
        try:
            with open(save_path + file_name + '.zip', 'wb') as code:

    return file_name + ' 下载完成!'

save_path = "projects(google)/"
fp = open('projects(google).txt', 'r')
for line in fp.readlines():
    url = line.strip()
    try:
        print(download(url, save_path))
    except:
        print(url, '下载失败!!!!!!')
fp.close()

3、下载成果如下所示：

开源当自立，无论发生什么，居安思危。

个人备份GitHub代码，仅用于学习

师夷长技以制夷，我国会有底层操作系统的，我国操作系统上，也会有强大的生态的！
