I want to update the content of the file on OneDrive item. For that I used this API.

PUT /drives/{drive-id}/items/{parent-id}:/{filename}:/content

This works perfectly fine for non China azure with Microsoft graph endpoint.

https://graph.microsoft.com

However, when I am trying this on AzureChina it is throwing me 501 error.

https://microsoftgraph.chinacloudapi.cn

Error:

This is the error response I am getting event though I am uploading data to file.

    {
    "error": {
        "code": "notSupported",
        "message": "Cannot upload content to an item representing a folder.",
        "innerError": {
            "date": "2021-05-10T09:01:12",
            "request-id": "98a8b075-bb90-42fe-8620-7303e669f4ec",
            "client-request-id": "98a8b075-bb90-42fe-8620-7303e669f4ec"
        }
    }
}

Is this not implemented in AzureChina? Another thing is graph explorer does not work with AzureChina. Is there separate graph explorer available for AzureChina?

According to this page OneDrive and Excel features of Graph API are limited by Microsoft Cloud China but without more details what exactly is not supported.

  • For me get items API is working for AzureChina. But not content API. I did found the Graph Explorer for AzureChina but looks like it is still in development. – Sanket Bhurke May 11 '21 at 05:52

For Azure China, Work around for Graph API is to use SharePoint REST API v1.

To upload the file contents of drive items

URL: https://{site_url}/_api/web/GetFolderByServerRelativeUrl('/Folder Name')/Files/add(url='newFile.txt',overwrite=true)
Headers:
"Accept": "application/json; odata=verbose",
"Authorization": "Bearer " + accessToken
Method: "POST",
Body:
<File_contents>

Auth URL: https://login.partner.microsoftonline.cn/{{TenantID}}/oauth2/v2.0/authorize

Access Token URL: https://login.partner.microsoftonline.cn/{{TenantID}}/oauth2/v2.0/token

Scope : https://{tenantId}-my.sharepoint.cn/.default

Make sure you have added appropriate API Permissions for SharePoint & granted Admin consent in Azure AD portal within corresponding Application.
