使用Microsoft Graph API獲取SharePoint文件夾和文檔

Question

我正在嘗試使用Microsoft Graph API從SharePoint文檔庫中獲取文件夾和文檔。

如果我對https://graph.microsoft.com/v1.0/sites/mysite.sharepoint.com:/sites/MyDocumentSite:/drives/進行GET請求， https://graph.microsoft.com/v1.0/sites/mysite.sharepoint.com:/sites/MyDocumentSite:/drives/得到以下信息：

{
    "@odata.context": "https://graph.microsoft.com/v1.0/$metadata#drives",
    "value":[
        {
            "createdDateTime": "2019-09-05T07:09:49Z",
            "description": "",
            "id": "b!wxh2ZWwoT0KKTdLRYjD5jvzjo8jkat5LgY3VyfgEqkv3YVg_XXXXXXXXXXXXXXXX",
            "lastModifiedDateTime": "2019-09-05T07:09:49Z",
            "name": "Documents",
            "webUrl": "https://mysite.sharepoint.com/sites/MyDocumentSite/Shared%20Documents",
            "driveType": "documentLibrary",
            "createdBy":{"user":{"displayName": "System Account" }},
            "lastModifiedBy":{"user":{"email": "me@myorganization.org", "id": "73f9990c-5c92-4839-8b13-XXXXXXXXXXXX", "displayName": "John Smith"…},
            "quota":{"deleted": 0, "remaining": 0, "total": 0, "used": 0}
        }
    ]
}

但是，如果我嘗試通過對該ID執行GET請求來訪問該驅動器： https://graph.microsoft.com/v1.0/sites/mysite.sharepoint.com:/sites/MyDocumentSite:/drives/b!wxh2ZWwoT0KKTdLRYjD5jvzjo8jkat5LgY3VyfgEqkv3YVg_XXXXXXXXXXXXXXXX : https://graph.microsoft.com/v1.0/sites/mysite.sharepoint.com:/sites/MyDocumentSite:/drives/b!wxh2ZWwoT0KKTdLRYjD5jvzjo8jkat5LgY3VyfgEqkv3YVg_XXXXXXXXXXXXXXXX :/ https://graph.microsoft.com/v1.0/sites/mysite.sharepoint.com:/sites/MyDocumentSite:/drives/b!wxh2ZWwoT0KKTdLRYjD5jvzjo8jkat5LgY3VyfgEqkv3YVg_XXXXXXXXXXXXXXXX MyDocumentSite: https://graph.microsoft.com/v1.0/sites/mysite.sharepoint.com:/sites/MyDocumentSite:/drives/b!wxh2ZWwoT0KKTdLRYjD5jvzjo8jkat5LgY3VyfgEqkv3YVg_XXXXXXXXXXXXXXXX drives/b! https://graph.microsoft.com/v1.0/sites/mysite.sharepoint.com:/sites/MyDocumentSite:/drives/b!wxh2ZWwoT0KKTdLRYjD5jvzjo8jkat5LgY3VyfgEqkv3YVg_XXXXXXXXXXXXXXXX ，出現BadRequest錯誤：

{
    "error":{
        "code": "BadRequest",
        "message": "Url specified is invalid.",
        "innerError":{
            "request-id": "7c9eaf61-764f-4d72-abdb-ffa2fe868e90",
            "date": "2019-09-16T19:09:41"
        }
    }
}

最終，我想要一種顯示文檔庫中所有文件夾和文檔的方法，但似乎無法超越這一初始步驟。

Answer 1

獲得要查詢的驅動器ID后，請在根目錄下使用/ drives發出請求：

https://graph.microsoft.com/v1.0/drives/<driveId>

Answer 2

使用“增量” API： https : //docs.microsoft.com/zh-cn/graph/api/driveitem-delta?view=graph-rest-1.0&tabs=http

第一次調用將返回所有項目。 （如果有分頁，則需要調用nextLink，直到收到deltaLink為止）。

您可能需要使用GET / sites / {siteId} / drive / root / delta或GET / drives / {drive-id} / root / delta之一

Answer 3

確實，當站點通過站點路徑尋址時，以下查詢將失敗，但例外：

GET `https://graph.microsoft.com/v1.0/sites/{hostname}:/{server-relative-path}/drive/root/children` 

由於類似的查詢，但這似乎是一個錯誤 ，但是當站點通過id尋址時，按預期方式工作：

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

要考慮的另一種選擇，是通過其標識符（不指定站點路徑或標識符）來獲取Drive資源，例如：

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

---

輪到在庫中獲取所有文檔和文件夾時， List children of a driveItem終結點的List children of a driveItem僅在當前文件夾下返回1級。

要返回所有驅動器項目，您至少可以考慮：

• 利用search方法 ，例如GET https://graph.microsoft.com/v1.0/drives/{drive-id}/root/search(q='')
• 通過List children of a driveItem端點的List children of a driveItem遞歸遍歷文件夾結構
