c# - 无法使用 Microsoft.Graph REST API 在根目录下创建新的 OneDrive 文件夹

问题描述

我可以在现有文件夹下创建文件夹，但不能在根目录下创建文件夹。我尝试了带有根 id 和路径语法的几种变体的 URL，例如“root:/./:”，但它们都没有创建文件夹。

我想看一个在 Microsoft.Graph REST API 的文档中的根目录下创建文件夹的示例。这可以节省很多时间。

感谢您的任何回答！

这是我的代码：

public static async Task<GameStorageItem> CreateFolderAsync(string parentId, string parentPath, 
                                                                string name)
    {
        var obj = new JObject
        {
            { "name", name },
            { "folder", new JObject() },
            { "@microsoft.graph.conflictBehavior", "fail" }
        };
        dynamic json;
        string content;
        if (parentId == "root")
        {
            content = await MicrosoftAccount.PerformHttpRequestAsync(HttpMethod.Get,
                                             $"me/drive", obj);
            json = JValue.Parse(content);
            parentId = json.id;

            //parentId = "root:./:";
        }
        content = await MicrosoftAccount.PerformHttpRequestAsync(HttpMethod.Post, $"me/drive/items/{parentId}/children", obj);
        json = JValue.Parse(content);
        DateTimeOffset created = json.createdDateTime;
        string id = json.id;
        var folder = new GameStorageFolder(name, $"{parentPath}/{name}", id, created, false);
        return folder;
    }
public static async Task<string> PerformHttpRequestAsync(HttpMethod method, string request, 
                                                             JObject json = null)
    {
        if (__authResult == null || await ValidateTokenAsync(5) == false)
        {
            try
            {
                await SignInAsync();
                __authResult = await __client.AcquireTokenSilent(scopes,
                                     __account).ExecuteAsync();
            }
            catch (MsalUiRequiredException)
            {
                //A MsalUiRequiredException happened on AcquireTokenSilentAsync. 
                //This indicates you need to call AcquireTokenAsync to acquire a token
                try
                {
                    //User must consent
                    __authResult = await __client.AcquireTokenInteractive(scopes)
                                         .ExecuteAsync();
                }
                catch (MsalException ex)
                {
                    //Error acquiring token
                    throw ex;
                }
            }
            catch (Exception ex)
            {
                //Error acquiring token silently
                throw ex;
            }
        }
        var builder = new UriBuilder(__graphUrl + request);
        return await PerformHttpRequestWithTokenAsync(method, builder.Uri, 
                                                      __authResult.AccessToken, json);
    }
private static async Task<string> PerformHttpRequestWithTokenAsync(HttpMethod method, 
                                      Uri uri, string token, JObject json = null)
    {
        HttpResponseMessage response;
        var httpClient = new HttpClient();

        var request = new HttpRequestMessage(method, uri);
        if (json != null)
        {
            request.Content = new StringContent(json.ToString(), Encoding.UTF8, 
                                                "application/json");
        }
        //Add the token in Authorization header
        request.Headers.Authorization = 
            new System.Net.Http.Headers.AuthenticationHeaderValue("Bearer", token);

        response = await httpClient.SendAsync(request);
        return await response.Content.ReadAsStringAsync();
    }

解决方案

您有三个不同的选项 - 我将它们显示为请求并让您将其转换为代码：

选项 1 - 发布给孩子

POST ../me/drive/root/children
{
  "name": "foo",
  "folder": {}
}

选项 2 - PUT 给孩子

PUT ../me/drive/root/children/foo
{
  "folder": {}
}

选项 3 - PUT 到路径

PUT ../me/drive/root:/foo
{
  "folder": {}
}

请注意，所有这些 URL 都引用根目录，然后使用不同的机制在其下创建文件夹。
