使用Microsoft Graph将文件上传到SharePoint驱动器

问题描述：

我们正在尝试使用Microsoft Graph rest API在Web应用程序和SharePoint Online之间实现集成.

We are trying to implement integration between a web application and SharePoint Online using Microsoft Graph rest API.

具体来说，我们需要将文件上传到特定SharePoint网站的文档库(驱动器)，而不是当前用户默认驱动器.我们可以通过Azure AD获得访问令牌，并且可以访问所有文件.

Specifically, we need to upload a file to a specific SharePoint site's document library (drive), different than current user default drive. We get the access token through Azure AD with access to all files.

我们可以使用/v1.0/me/drive/...将文件上传到任何驱动器，但是当我们使用其他驱动器时则不能.

We can upload files into any drive using /v1.0/me/drive/... but not when we use another drive.

例如:

var response = client.PutAsync(graphResourceUrl +
    "/beta/sharepoint/sites/" + siteCollSiteId +
    "/lists/" + listId +
    "/drive/root/children/" + fileName + ":/content",
    new ByteArrayContent(fileBytes)).Result;

var response = client.PutAsync(graphResourceUrl +
    "/beta/drives/" + "/" + listId +
    "/items/" + siteCollSiteId + "/" + fileName + ":/content",
    new ByteArrayContent(fileBytes)).Result;

var response = client.PutAsync(graphResourceUrl +
    "/beta/drives/" + listId + "/" + fileName + ":/content",
    new ByteArrayContent(fileBytes)).Result;

/v1.0和/beta(在SharePoint包含路径的情况下)我们都收到Not Implemented的错误响应.

Both /v1.0 and /beta (in the case of SharePoint containing path) we are getting an error response of Not Implemented.

我们可能做错了什么?它是否还不能与Microsoft Graph(/me除外)一起使用?

What could we be doing wrong? Is it not yet working with Microsoft Graph (other than /me)?

答

为了使用v1.0获取驱动器的所有文件，您首先需要获取访问令牌(我看到您已经通过了该访问令牌) )，然后获取"drive-id"并使用以下网址(注意:它不是"drive"，而是"drives"):

In order to get all the files of a drive using v1.0, you would first need to get an access token (which I see you are already passed that), then get the 'drive-id' and use the following URL(note: its not 'drive' it is 'drives'):

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

要获取驱动器ID，我使用邮递员发出了以下GET请求，它将列出站点上的所有驱动器，您将能够获取该驱动器的ID:

To get the drive id, I made the following GET request using postman, this will list all the drives on the site and you will be able to get the ID of that drive:

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

要回答有关上传文件的问题，您将向以下URL发出PUT请求:

To answer your question regarding Uploading files, you will make a PUT request to the following URL:

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

您将需要设置两个必需的标题:

You will need to set two required headers:

授权
内容类型

接下来，您将把文件的二进制流传递到请求的主体中.

Next, you will pass the binary stream of the file into the body of the request.

其他有用的项目

获取文件夹中的所有文件:

Get all files inside of a folder:

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

获取用户OneDrive的内容:

Get content of users OneDrive:

https://graph.microsoft.com/v1.0/me/drive/root/children
