使用 Microsoft Graph 将文件上传到 SharePoint 驱动器 [英] Upload file to SharePoint drive using Microsoft Graph

问题描述

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

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)，不同于当前用户的默认驱动器.我们通过 Azure AD 获取访问令牌，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，但当我们使用另一个驱动器时则不行.

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 一起使用(/me 除外)?

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

推荐答案

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)，然后获取驱动器 ID"并使用以下 URL(注意:它不是驱动器"，而是驱动器"):

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

为了获取驱动器 ID，我使用 postman 发出以下 GET 请求，这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，您将文件的二进制流传递到请求正文中.

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