Github API创建提交

我需要有关Github API的帮助，

I need help with Github API,

我需要通过api提交新版本的文件，我正在尝试通过向

I need commit new version of file through api, I'm trying to achieve this by sending post request to

https://api.github.com/repos/:username/:repo:/git/commits/

有数据

{
    "login": "username",
    "token": "auth_token",
    "parent_commit": "sha",
    "message": "commit message.",
    "content": {
        "path": "full/path",
        "mode": "edit",
        "data": "new content"
    }
}

但是它失败并显示结果-找不到.

But it fails with result - not found.

有没有人知道将请求发送到哪里以及这种格式是否正确?

Have anyone idea where to send this request and if this format is right?

(格式由- http://swanson.github.com/blog/2011/07/23/digging-around-the-github-api-take-2.html )

谢谢！
