我正在尝试使用 c# 使用 GitHub DB API 更新文件。执行此操作的过程在此处定义http://developer.github.com/v3/git/，如下所示
- 获取当前提交对象
- 检索它指向的树
- 检索该特定文件路径的树具有的 blob 对象的内容
- 以某种方式更改内容并使用该新内容发布一个新的 blob 对象，返回一个 blob SHA
- 发布一个新的树对象，该文件路径指针替换为您的新 blob SHA * 获取树 SHA
- 以当前提交 SHA 作为父级和新树 SHA 创建一个新提交对象，获取一个提交 SHA
- 更新分支的引用以指向新的提交 SHA
但是，当我到达点时它失败了
更新分支的引用以指向新的提交 SHA

var updateReferenceResponse = Patch<UpdateReferenceResponse>("git/refs/heads/master", updateReferenceRequest);
响应失败
<html><body><h1>502 Bad Gateway</h1>
The server returned an invalid or incomplete response.
</body></html>
这是我试图调用的特定 API http://developer.github.com/v3/git/refs/#update-a-reference
这是代码的主要工作原理
