Question

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http://developer.github.com/v3/git/定义，如下所示

获取当前提交对象
检索它指向的树
检索树对该特定文件路径的blob对象的内容
以某种方式更改内容并使用该新内容发布新的blob对象，然后获取blob SHA
发布一个新的树对象，该文件路径指针替换为新的blob SHA *获取树SHA回来
使用当前提交SHA作为父树和新树SHA创建一个新提交对象，获取提交SHA
更新分支的引用以指向新提交SHA

然而，当我到达

时，它失败了

更新分支的引用以指向新提交SHA

即行

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>

以下是我尝试调用http://developer.github.com/v3/git/refs/#update-a-reference

的具体API

以下是代码

的主要工作方式

Posting to https://api.github.com/repos/simoncropp/test/git/commits with data
{
  "message": "foo",
  "tree": "fd1379d51016989a615acf79409256849dc8ea7f",
  "parent": [
    "a4447748c9cd36601127e3a6143348a1695cc2e8"
  ]
}

文档在这里需要parents参数，而不是parent。

response:
{
  "sha": "f66832493d22c58a6dd9d41b65504c1e9c901d7a",
  "tree": {
    "sha": "fd1379d51016989a615acf79409256849dc8ea7f",
  },

}

如果没有它，你会获得一个空的父提交数组，而糟糕的事情将会发生。
