通过 GitHub 的 API 获取代码

GitHub 的 API 功能很强大，也很规范。基本都是以 GET 方式从 https://api.github.com/ 取得。
假如要获得代码库里的 readme，使用使用 GET /repos/:owner/:repo/readme
比如 Typecho 的肥皂库 https://api.github.com/repos/typecho-fans/plugins/readme
通过浏览器输入地址，或是使用curl或者其他方法取得页面内容，注意通过curl等方式要设置User-Agent。
返回值为 json 编码的 stdClass，content 属性为源码的 base64 编码，去掉'\n'再用 base64 方式解码就取得文件源码。

如果要取得代码文件内容，需要获取相应的目录和文件内容：

GET /repos/:owner/:repo/contents/:path

比如要获取肥皂库的根目录下的内容：

https://api.github.com/repos/typecho-fans/plugins/contents/

[  {  "name": "At",  "path": "At",  "sha": "668a750a5aae5d9187cebfd74f10e43e47d338bc",  "size": null,  "url": "https://api.github.com/repos/typecho-fans/plugins/contents/At?ref=master",  "html_url": "https://github.com/typecho-fans/plugins/tree/master/At",  "git_url": "https://api.github.com/repos/typecho-fans/plugins/git/trees/668a750a5aae5d9187cebfd74f10e43e47d338bc",  "type": "dir",  "_links": {  "self": "https://api.github.com/repos/typecho-fans/plugins/contents/At?ref=master",  "git": "https://api.github.com/repos/typecho-fans/plugins/git/trees/668a750a5aae5d9187cebfd74f10e43e47d338bc",  "html": "https://github.com/typecho-fans/plugins/tree/master/At"  }  },  {  "name": "AutoSlug",  "path": "AutoSlug",  "sha": "e0832144c0af0f5bccfd4f44faa4cfde1e5017cf",  "size": null,  "url": "https://api.github.com/repos/typecho-fans/plugins/contents/AutoSlug?ref=master",  "html_url": "https://github.com/typecho-fans/plugins/tree/master/AutoSlug",  "git_url": "https://api.github.com/repos/typecho-fans/plugins/git/trees/e0832144c0af0f5bccfd4f44faa4cfde1e5017cf",  "type": "dir",  "_links": {  "self": "https://api.github.com/repos/typecho-fans/plugins/contents/AutoSlug?ref=master",  "git": "https://api.github.com/repos/typecho-fans/plugins/git/trees/e0832144c0af0f5bccfd4f44faa4cfde1e5017cf",  "html": "https://github.com/typecho-fans/plugins/tree/master/AutoSlug"  }  },//省略掉了很多  {  "name": "XiaMiPlayer",  "path": "XiaMiPlayer",  "sha": "6fe21b2edf53e975e8ee4268aff5b757f2ea744d",  "size": null,  "url": "https://api.github.com/repos/typecho-fans/plugins/contents/XiaMiPlayer?ref=master",  "html_url": "https://github.com/typecho-fans/plugins/tree/master/XiaMiPlayer",  "git_url": "https://api.github.com/repos/typecho-fans/plugins/git/trees/6fe21b2edf53e975e8ee4268aff5b757f2ea744d",  "type": "dir",  "_links": {  "self": "https://api.github.com/repos/typecho-fans/plugins/contents/XiaMiPlayer?ref=master",  "git": "https://api.github.com/repos/typecho-fans/plugins/git/trees/6fe21b2edf53e975e8ee4268aff5b757f2ea744d",  "html": "https://github.com/typecho-fans/plugins/tree/master/XiaMiPlayer"  }  }]

获取目录的返回值为一个 json 编码的数组，数组的每项为一个 stdClass。通过循环读取对应的url就可以取得所有文件内容。
库内其他文件或目录的获取方式就在 contents/ 后面加上对于的路径，比如：

https://api.github.com/repos/typecho-fans/plugins/contents/At/Plugin.php

再配合 Cron 就可以定时同步 GitHub 上的代码了。
