使用Azure DevOps Rest API重命名文件

Question

我正在创建一个Azure函数，用于重命名Azure DevOps存储库中的文件，但需要"oldObjectId"，这是Get-Commits API调用(即(的最后一个"commitId">

得到https://dev.azure.com/｛organization｝/｛project｝/_apis/git/restores/{repositoryId｝/提交？api版本=6.0

我正在本地和通过PostMan测试代码，但不知道在请求的主体中包含什么，因为没有为此指定任何内容。

我对C#和Azure函数还很陌生，不知道如何在自己的项目中正确实现它。如果有人能指引我走向正确的方向，我将不胜感激。

我使用的是带有.NET Core 3.0和Azure函数的Visual Studio。

这是迄今为止的代码：

关于这个问题，请参考以下代码

Client.DefaultRequestHeaders.Accept.Add(
new MediaTypeWithQualityHeaderValue("application/json"));
Client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic",
Convert.ToBase64String(
ASCIIEncoding.ASCII.GetBytes(
string.Format("{0}:{1}", "", PAT))));
var requestMessage = new HttpRequestMessage(HttpMethod.Get, "https://dev.azure.com/{organization}/{project}/_apis/git/repositories/{repositoryId}/commits?api-version=6.0-preview.1&searchCriteria.$top=1");
string content = string.Empty;
using (HttpResponseMessage response = await Client.SendAsync(requestMessage))
{
if (!response.IsSuccessStatusCode)
{
try
{
response.EnsureSuccessStatusCode();
}
catch (HttpRequestException ex)
{
throw ex;
}

}
var res = await response.Content.ReadAsStringAsync();
JObject resObj = JsonConvert.DeserializeObject<JObject>(res);
var commitId = (resObj["value"].Last).Value<string>("commitId");
log.LogInformation("commitId: "+ commitId);
var renameFileRequestBody = new
{
refUpdates = new Object[] {
new {
name = "refs/heads/master",
oldObjectId = commitId,
},
},

commits =new Object[] {
new{
comment = "Renaming test.txt to mytest.txt",
changes = new Object[]{
new{
changeType = "rename",
sourceServerItem = "/test.txt",
item = new
{
path = "/mytest.txt",
}
},
}
}

}
};
HttpRequestMessage renameFileRequest = new HttpRequestMessage(HttpMethod.Post, "https://dev.azure.com/{organization}/{project}/_apis/git/repositories/{repositoryId}/pushes?api-version=6.1-preview.2");
renameFileRequest.Content = new StringContent(JsonConvert.SerializeObject(renameFileRequestBody), Encoding.UTF8, "application/json");
using (HttpResponseMessage renameFileResponse=await  Client.SendAsync(renameFileRequest))
{
if (renameFileResponse.StatusCode == HttpStatusCode.Created)
{
return new OkObjectResult("File is renamed successfully!");
}
else
{
return new BadRequestObjectResult("File could not be renamed successfully."); // 400
}

}
