使用 Azure DevOps Rest API 重命名文件

Question

I'm creating an Azure function for a renaming a file in an Azure DevOps Repository but need the 'oldObjectId' which is the last 'commitId' from the Get Commits API call ie

GET https://dev.azure.com/{organization}/{project}/_apis/git/repositories/{repositoryId}/commits?api-version=6.0

我正在本地和通过 PostMan 测试代码，但不知道要在请求正文中包含什么，因为没有为此指定任何内容。

我对 C# 和 Azure 函数很陌生，不知道如何在我自己的项目中正确实现它。 如果有人能引导我走向正确的方向，我将不胜感激。

我正在使用带有 .NET Core 3.0 和 Azure 函数的 Visual Studio。

这是到目前为止的代码：

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)
