无法从 C# 和图形资源管理器中的 Sharepoint 图形获取驱动器项目和驱动器文件夹答案

【问题标题】：Failing to getting Drive items and Drive Folders from Sharepoint Graph in C# and Graph Explorer无法从 C# 和图形资源管理器中的 Sharepoint 图形获取驱动器项目和驱动器文件夹
【发布时间】：2019-11-07 10:16:34
【问题描述】：

我在使用 Graph Drive 项目时遇到了一些问题。我正在尝试访问具有特定结构的文件以读取、写入和更新文件夹中的文件。问题是我无法访问潜在客户文件夹地图，我在 C# 和 Graph Explorer 中尝试了不同的可能性。

文件夹结构 ► MySite.sharepoint.com ► MyUnderSite ► MainDriveFlder ► CustomerDriveFolder ► Driveitems

和

MySite ► MyUnderSite ► MainDriveFlder ► DriveItems

MySite = 站点/CustomerSitename.sharepoint.com：
MyUnderSite = 站点/CustomerSitename.sharepoint.com:/sites/CustomerSitename2:
MainDriveFlder = Customer_Files
CustomerDriveFolder = CustomerNr1_Files
Driveitems = word.docs 或 pic.png 或 exel.xlsx

我尝试了什么

在 C# 中

graphserviceClient.Sites["MySite.sharepoint.com:/sites/MyUnderSite:"].Drives.Request().GetAsync();
graphserviceClient.Sites["MySite.sharepoint.com:/sites/MyUnderSite:"].Drives[""].Request().GetAsync();

https://graph.microsoft.com/v1.0/drives/{drive-id}/root/children

graphserviceClient.Sites["MySite.sharepoint.com:/sites/MyUnderSite:"].Drives["Customer_Files"].Root.Children.Request().GetAsync();

https://graph.microsoft.com/v1.0/sites/{tenant}.sharepoint.com:{path-to-site(ie: /sites/HR)}:/drives

graphserviceClient.Sites["MySite.sharepoint.com:/sites/MyUnderSite:"].Drives.Request().GetAsync();

https://graph.microsoft.com/v1.0/drives/{drive-id}/root:/{folder-name}/{file-name.txt}:/content

graphserviceClient.Sites["MySite.sharepoint.com:/sites/MyUnderSite:"].Drives["Customer_Files"].Items["ID"].Request().GetAsync();

https://graph.microsoft.com/v1.0/drives/{drive-id}/root:/{folder-name}:/children https://graph.microsoft.com/v1.0/me/drive/root/children

图形浏览器 这行得通，我得到了回应 https://graph.microsoft.com/v1.0/sites/MySite.sharepoint.com:/sites/MyUnderSite:/drives

然后，我收到一个文件名 = "name": "Customer_Files" 的响应，即 "driveType": "documentLibrary"

但是当我进一步进入这个文件夹或想从中调用项目时，我无法访问它们，C# 同样的问题。尽管没有正确的 URL 规范，但我已经尝试了所有这些并且没有对错误做出响应。（我尝试过的部分）

所以主要问题是我无法访问或调用 Customer_Files 和 Customer_Files/Customernr1_Files 中的文件。

谁能帮助我在 c# 和图形资源管理器中找到正确的结构。访问这些文件。如果我提供的信息有误或信息较少，请告诉我。我已经找了好几个星期了。

我无法提供所有信息并更改一些代号以保护客户。

【解决方案1】：

根据您的结构，我无法判断您的“MyUnderSite”是“MySite”的子网站还是其他网站集。

我将分析这两种情况。

“MyUnderSite”是一个网站集：

致电GET https://graph.microsoft.com/v1.0/sites/MySite.sharepoint.com:/sites/MyUnderSite 获取“MyUnderSite”的 id。
致电GET https://graph.microsoft.com/v1.0/sites/{id of "MyUnderSite"}/drive/root:/customer_files。

“MyUnderSite”是一个子网站：

致电GET https://graph.microsoft.com/v1.0/sites/MySite.sharepoint.com/sites 列出子站点并找到“MyUnderSite”的 id。
致电GET https://graph.microsoft.com/v1.0/sites/{id of "MyUnderSite"}/drive/root:/customer_files。

谢谢！你回答它真的帮助我前进，现在我找到了解决方案。我正在尝试纯名称 ID，但从未尝试使用项目和驱动项/文件夹的原始 ID。我将通过解决方案更新我的问题。我发现。也许它会再次帮助人们解决同样的问题，Allen Wu。
@BEvilM 我很高兴知道我的回答很有帮助。您可以发布您的最终解决方案作为帮助更多人的答案:)

【解决方案2】：

解决方案

var returnitem = await graphserviceClient.Sites["Site-ID"].Drives["Dive-ID"].Root.Children.Request().GetAsync();//gets all Children in the drive

var returnitemfiles = await graphserviceClient.Sites["Site-ID"].Drives["Drive-ID"].Items["File-ID"].Children.Request().GetAsync();//gets one Child and returns all the Children of that file

var returnitemfile = await graphserviceClient.Sites["Site-ID"].Drives["Dive-ID"].Items["File-ID"].ItemWithPath(fileBase.FileName).Content.Request().PutAsync<DriveItem>(fileBase.InputStream);//upload a file to the drive in a folder by id only usable for small files under 4 MB

Site-ID 可能看起来像这样 = "c6669213-7e4f-44c9-a792-65737055c13f"

潜水 ID ="b!iDh2xo8-yUSnkkcTcFXBP_aUL5EMu9JIqr1aGCz2KH9m3E7rhgkqRLyqiK93Z96_"

文件夹 ID = "01BPZAU2WZBX5ZT55GHTCYVV3WZERIWJM6"

FileBase 我使用了 HttpPostedFileBase
