使用 Microsoft Graph API 下載 Sharepoint 文件未顯示內容屬性

Question

我正在嘗試使用 Microsoft Graph API 從 SharePoint Online 下載文件。 Graph API 不允許我使用 /Content。

這是我正在使用的端點：

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

這就是得到（值已刪除）：

{
"@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"
}

}

當我嘗試添加 /content 時，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 下載此文件？

Answer 1

端點https://graph.microsoft.com/v1.0/sites/{site-id}/lists/{list-id}/items/{item-id}返回ListItem資源，但Content是DriveItem資源的屬性哪一個

表示驅動器中的項目，如文檔、照片、視頻或文件夾資源

這就是發生此錯誤的原因。

鑒於提供的端點，它可以修改為

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