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.

import

sys

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.

for

curLine in allLines:

09.

if

curLine.find(

'repo-list-name'

)
>=

0

:

10.

flag = True

11.

if

flag:

12.

pos = curLine.find(

'href="'

)

13.

if

pos >=

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.

if

prefix >=

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

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.

for

page 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.

#

((i=

;
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.

for

page 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：
