我需要获取我的Github仓库的README内容，我使用了'Get the README' API V3，但它是以base64编码的：
{
"name": "README.rdoc",
"path": "README.rdoc",
"sha": "d21b593aedfa49030478ead89c4ac991268c75c0",
"size": 4939,
"url": "https://api.github.com/repos/lgs/paymill-on-rails/contents/README.rdoc?ref=master",
"html_url": "https://github.com/lgs/paymill-on-rails/blob/master/README.rdoc",
"git_url": "https://api.github.com/repos/lgs/paymill-on-rails/git/blobs/d21b593aedfa49030478ead89c4ac991268c75c0",
"type": "file",

...
...,
"encoding": "base64",
"_links": {
"self": "https://api.github.com/repos/lgs/paymill-on-rails/contents/README.rdoc?ref=master",
"git": "https://api.github.com/repos/lgs/paymill-on-rails/git/blobs/d21b593aedfa49030478ead89c4ac991268c75c0",
"html": "https://github.com/lgs/paymill-on-rails/blob/master/README.rdoc"
}
}
如何获取/转换“content”：“PT0gUGF5bWlsbCBv ...”为明文（非base64编码）？
更新（仅供跟踪目的）：
Linuxios提出的解决方案也可以在美好的Octokit API wrapper for Ruby中实现，如下所示：
Octokit.contents 'lgs/paymill-on-rails', :path => 'README.rdoc', :accept => 'application/vnd.github.html'
获取整个HTML和
Octokit.contents 'lgs/paymill-on-rails', :path => 'README.rdoc', :accept => 'application/vnd.github.V3.raw'
如果您只想要干净、原始的内容：
2.0.0p247 :001 > require 'octokit'
=> true
2.0.0p247 :002 > Octokit.contents 'lgs/paymill-on-rails', :path => 'README.rdoc', :accept => 'application/vnd.github.V3.raw'
