从github下载最新Android源码

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，可以使用下面的命令获取远程仓库的代码：

view sourceprint?

1.git clone [仓库URL]

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，如果只是要配置“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：

得到所有项目的git仓库URL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：

view sourceprint?

1.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:

view sourceprint?

1.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）：

view sourceprint?

1.for((i=1; i<=5; i++));do

2.curl https://github.com/android?page=$i > android.github.com.$i.html;

3.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：

view sourceprint?

1.https://github.com/android/platform_frameworks_base

仓库URL是：

view sourceprint?

1.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：

view sourceprint?

1.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="xxx">）被一个<h3 class="repo-list-name">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<h3 class="repo-list-name">的下一行）。

根据刚才找到的两个规律：

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

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）：

view sourceprint?

01.#!/usr/bin/python

02.importsys

03. 

04.flag = False

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

06. 

07.allLines = sys.stdin.readlines()

08.forcurLine in allLines:

09.ifcurLine.find('repo-list-name') >=0:

10.flag = True

11.ifflag:

12.pos = curLine.find('href="')

13.ifpos >= 0:

14.pos += len('href="')

15.last = curLine[pos:]

16.end = last.find('"')

17.link = last[:end]

18. 

19.# name to path.

20.name = link[link.rfind('/')+1:]

21.prefix = name.find('platform_')

22.ifprefix >= 0:

23.name = name[len('platform_'):] # ignore platform_

24.path = name.replace('_','/')

25. 

26.link = link_prefix + link

27.# print'curl', link, '>', name

28.# https://github.com/android/platform_external_qemu.git

29.print'git clone', link + '.git', path # 输出 git clone 命令

30.flag = False

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：

view sourceprint?

1../getGitRepos.py < android.github.com.1.html

该命令的输出为：

view sourceprint?

01.git clone https://github.com/android/platform_dalvik.git dalvik

02.git clone https://github.com/android/platform_bionic.git bionic

03.git clone https://github.com/android/platform_system_core.git system/core

04.git clone https://github.com/android/kernel_common.git kernel/common

05.git clone https://github.com/android/platform_external_qemu.git external/qemu

06.git clone https://github.com/android/platform_build.git build

07.git clone https://github.com/android/platform_development.git development

08.git clone https://github.com/android/platform_frameworks_base.git frameworks/base

09.git clone https://github.com/android/platform_manifest.git manifest

10.git clone https://github.com/android/platform_frameworks_support.git frameworks/support

11.git clone https://github.com/android/platform_packages_apps_settings.git packages/apps/settings

12.git clone https://github.com/android/platform_external_dhcpcd.git external/dhcpcd

13.git clone https://github.com/android/platform_external_webkit.git external/webkit

14.git clone https://github.com/android/platform_external_protobuf.git external/protobuf

15.git clone https://github.com/android/platform_packages_providers_mediaprovider.git packages/providers/mediaprovider

16.git clone https://github.com/android/platform_external_elfutils.git external/elfutils

17.git clone https://github.com/android/platform_external_strace.git external/strace

18.git clone https://github.com/android/platform_hardware_libhardware.git hardware/libhardware

19.git clone https://github.com/android/platform_external_tinyxml.git external/tinyxml

20.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：

view sourceprint?

1.forpage in `ls android.github.com.*`; do

2.echo parse $page

3../getGitRepos.py < $page >> gitRepos.txt;

4.done

有了写满git clone命令的gitRepos.txt后，可以使用如下命令执行之：

view sourceprint?

1.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：

view sourceprint?

01.#!/bin/bash

02.# clone AOSP each repo from https://github.com/android

03.#this shell depends on git, curl and python2.

04.# INSTALL depends:

05.#   sudo apt-get install git curl python

06.#

07.# by xu([e-mail]).

08. 

09.# download github AOSP sub pages

10.for((i=1; i<=5; i++));do

11.echo get AOSP subpage https://github.com/android?page=$i

12.curl https://github.com/android?page=$i > android.github.com.$i.html;

13.done

14. 

15.# parse git repo URL from each sub pages

16.mkdir repos

17.cat /dev/null> gitRepos.txt

18.forpage in `ls android.github.com.*`; do

19.echo parse $page

20../getGitRepos.py < $page >> gitRepos.txt;

21.done

22. 

23.# clone repos

24.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：
