从github下载最新Android源码

2024-07-23 22:03:53   224人阅读

今年5月底开始，谷歌彻底被墙，所有谷歌的网站都不能访问了，这次包括了android.org，googlesource.com，code.google.com。Android官方的资源不能访问，想下载Android代码当然是困难重重了。

本文就为大家解决这一问题——介绍如何使从github.com/andorid下载Andorid最新源码。俗话说“授之以鱼不如授之以渔”，本文不只是给出一个已经打包好的源码的链接，而是重现一下我是如何下载的，希望对大家遇到的类似的问题能有所帮助。


github.com/android简介

打开github.com/android可以看到：

中间黑体列出的的是各个项目的链接。github.com/android上托管的Android源码是用git单独管理每个项目的，而没有像googlesource.com那样使用repo（谷歌开发的基于git的命令行工具）管理所有项目。所以，如果你只想下载一个项目的源码，可以单独下载（比如开发App想跟一下SDK的一些源码可以下载platform_frameworks_base项目）。


怎么下载一个项目的代码？

用过git的同学当然知道：

git clone [仓库URL]
就可以了，github项目页面的右边栏给出了仓库URL，如下图（clone URL下方的文本框）：


当然，如果你只要配置“App源码调试”环境，可以点“Download ZIP”按钮，下载zip格式的源码包，然后在Eclipse调试的时候选择下载好的源码包。


如何批量下载github上的Android源码

这里在是本文的重点——批量下载github上的android源码。

根据单独下载一个项目的过程，下载所有项目的源码可以有两种方法：

  1. 得到所有项目的git仓库URL
  2. 得到所有项目的ZIP包下载链接

接下来的问题是如何得到这样的URL?

当然是从网页上（也就是页面的HTML文件上）！

现在问题就是如何得到这些网页？

我瞬间想到的办法就是——用CURL

ps: CURL是一个命令行上传下载工具，支持多种协议包括HTTP, HTTPS, FTP等。

没有curl的同学可以用如下命令下载：

sudo apt-get install curl

有了CURL用来抓页面，就不愁得不到仓库URL或ZIP包URL了：

首先要抓取github.com/android的页面，再“顺藤摸瓜”地抓取各个项目的页面，再从各项目的页面上抓取仓库URL或ZIP包URL。


抓取页面

在github.com/android页面的下方可以看github.com/andoid一共分5页，点击后面几个页面，可以发现这几个页面的URL形式一致为:

https://github.com/android?page=N
其中N表示“第几页”，比如第二页，就是https://github.com/android?page=2

由此，可以用bash脚本轻易写出抓取这5个页面的代码（可以直接在终端里执行下面的命令）：

for ((i=1; i<=5; i++)); do
	curl https://github.com/android?page=$i > android.github.com.$i.html;
done

有捷径

再看项目的首页URL和仓库URL可以发现：

仓库URL = 首页URL + .git

比如，platform_frameworks_base的首页URL是：

https://github.com/android/platform_frameworks_base
仓库URL是：

https://github.com/android/platform_frameworks_base.git
当然，如果你有github.com的帐号，并且当前环境的pubkey已加入到了profile下，也可以使用ssh协议下载（而不是https），ssh下载的URL是：

git://github.com/android/platform_frameworks_base.git
由此可知，获取仓库URL可以不用进一步抓起项目首页，更简单（下面只介绍获取所有仓库URL）。

解析页面

现在的问题就是——如何从这些页面上得到仓库的URL了。

可以通过浏览器的“审查元素”菜单快速找到页面上一个链接对应的HTML代码块，如下图：


可以看到platform_frameworks_base项目的超链接（<a href=http://www.mamicode.com/"xxx">）被一个

标签包围，粗略浏览一下刚才下载的几个子页面，可以看出每个项目首页的链接都是如此（在

的下一行）。

根据刚才找到的两个规律：

  1. 项目首页URL总是出现在<h3 class="repo-list-name">的下一行

  2. 仓库URL = 首页URL + .git

可以写出解析各个项目首页（仓库URL）的python代码（getGitRepos.py）：

#!/usr/bin/python
import sys

flag = False
link_prefix = 'https://github.com' # 如果使用ssh协议下载，可将https改为git

allLines = sys.stdin.readlines()
for curLine in allLines:
	if curLine.find('repo-list-name') >= 0:
		flag = True
	if flag:
		pos = curLine.find('href=http://www.mamicode.com/"')>之所以用python解析，只是因为python写起来简洁，也可以用其他语言。
这段python程序从标准输入读入文本并解析，实际使用时可用重定向操作符实现，实现用之前抓取的github.com/android的几个子页面替代标准输入。
程序输出的git clone命令的path参数会忽略仓库名称前面的platform_前缀，这使得最终下载下来的源码结构和repo sync下来的类似。

可以先用一个页面测试一下，看看解析出来的URL对不对（上面的python代码就是这样改正确的），终端输入下面命令：
./getGitRepos.py < android.github.com.1.html
该命令的输出为：
git clone https://github.com/android/platform_dalvik.git dalvik
git clone https://github.com/android/platform_bionic.git bionic
git clone https://github.com/android/platform_system_core.git system/core
git clone https://github.com/android/kernel_common.git kernel/common
git clone https://github.com/android/platform_external_qemu.git external/qemu
git clone https://github.com/android/platform_build.git build
git clone https://github.com/android/platform_development.git development
git clone https://github.com/android/platform_frameworks_base.git frameworks/base
git clone https://github.com/android/platform_manifest.git manifest
git clone https://github.com/android/platform_frameworks_support.git frameworks/support
git clone https://github.com/android/platform_packages_apps_settings.git packages/apps/settings
git clone https://github.com/android/platform_external_dhcpcd.git external/dhcpcd
git clone https://github.com/android/platform_external_webkit.git external/webkit
git clone https://github.com/android/platform_external_protobuf.git external/protobuf
git clone https://github.com/android/platform_packages_providers_mediaprovider.git packages/providers/mediaprovider
git clone https://github.com/android/platform_external_elfutils.git external/elfutils
git clone https://github.com/android/platform_external_strace.git external/strace
git clone https://github.com/android/platform_hardware_libhardware.git hardware/libhardware
git clone https://github.com/android/platform_external_tinyxml.git external/tinyxml
git clone https://github.com/android/platform_external_oprofile.git external/oprofile
测试基本上出现问题，因为getGitRepos.py输出的是git clone命令，执行之后在能执行实际的下载动作；所以，需要将这些输出保存下来；
使用如下命令可将每个子页面解析出的git clone命令保存到一个文本文件内：
for page in `ls android.github.com.*`; do
	echo parse $page
	./getGitRepos.py < $page >> gitRepos.txt;
done
有了写满git clone命令的gitRepos.txt后，可以使用如下命令执行之：
sh gitRepos.txt

一键下载
为了方便广大网友使用，我已将上面需要用的命令写道了下面的cloneRepos.sh：
#!/bin/bash
# clone AOSP each repo from https://github.com/android
# this shell depends on git, curl and python 2.
# INSTALL depends:
#	sudo apt-get install git curl python
#
# by xu(xusiwei1236@163.com).

# download github AOSP sub pages
for ((i=1; i<=5; i++)); do
	echo get AOSP subpage https://github.com/android?page=$i
	curl https://github.com/android?page=$i > android.github.com.$i.html;
done

# parse git repo URL from each sub pages
mkdir repos
cat /dev/null > gitRepos.txt
for page in `ls android.github.com.*`; do
	echo parse $page
	./getGitRepos.py < $page >> gitRepos.txt;
done

# clone repos
sh gitRepos.txt
另外，我已将上面的cloneRepos.sh和getGitRepos.py打包在了一起，可以到http://download.csdn.net/detail/xusiwei1236/7960925下载使用。
当然，如果觉得自己运行麻烦，可以直接copy生成的gitRepos.txt，直接粘贴到终端里执行之，即可下载全部Android源码：
