使用 Microsoft Graph API 下载 Sharepoint 文件未显示内容属性

Question

我正在尝试使用 Microsoft Graph API 从 SharePoint Online 下载文件。Graph API 不允许我使用 /Content。

这是我正在使用的端点：

https://graph.microsoft.com/v1.0/sites/<host.sharepoint.com>/lists/<ListID>/items/<ItemID>

这就是得到（值已删除）：

{
"@odata.context","@odata.etag","createdDateTime","eTag","id","lastModifiedDateTime","webUrl","createdBy"{"user": {"email","id","displayName"}},   "lastModifiedBy": {"user": {"email","id","displayName"}},
"parentReference": {"id"},
"contentType": {"id"},
"fields@odata.context",
"fields": {"@odata.etag","FileLeafRef","id","ContentType","Created",    "AuthorLookupId","Modified","EditorLookupId","_CheckinComment",      "LinkFilenameNoMenu","LinkFilename","DocIcon","FileSizeDisplay",       "ItemChildCount","FolderChildCount","_ComplianceFlags","_ComplianceTag",        "_ComplianceTagWrittenTime","_ComplianceTagUserId","_CommentCount",        "_LikeCount","Edit","_UIVersionString","ParentVersionStringLookupId",       "ParentLeafNameLookupId"
}

}

当我尝试添加 /content 时，我得到：

{
"error": {
    "code": "BadRequest",
    "message": "Resource not found for the segment 'content'.",
    "innerError": {
        "request-id": "<ReqID>",
        "date": "<date>"
    }
}

}

如何使用 API 下载此文件？

Answer 1

端点https://graph.microsoft.com/v1.0/sites/{site-id}/lists/{list-id}/items/{item-id}返回ListItem的资源却Content是一个性质DriveItem的资源，其

表示驱动器中的项目，如文档、照片、视频或文件夹资源

这就是发生此错误的原因。

鉴于提供的端点，它可以修改为

GET https://graph.microsoft.com/v1.0/sites/{site-id}/lists/{list-id}/items/{item-id}/driveItem/content

以下载内容
