Question

Is it possible to make REST calls from Graph Api sdk using GraphClient

Parth Jani 90

Hello

I was trying to make this SharePoint Rest call using Graph sdk:
https://tenant.sharepoint.com/sites/SiteInfi2022/_api/web/lists/getbytitle('hen')/items(1)?$expand=AttachmentFiles

refer code below :


            var requestInformation = new RequestInformation()
            {
                HttpMethod = Method.GET,
                URI = new Uri("https://tenant.sharepoint.com/sites/SiteInfi2022/_api/web/lists/getbytitle('hen')/items(1)?$expand=AttachmentFiles")
               

            };
           requestInformation.Headers.Add("Accept", "application/xml");
            requestInformation.Headers.Add("Content-Type", "application/xml");
            requestInformation.Headers.Add("Prefer", "HonorNonIndexedQueriesWarningMayFailRandomly");
        

            var nativeResponseHadnler = new NativeResponseHandler();
            requestInformation.SetResponseHandler(nativeResponseHadnler);
            var asdfsf = GraphClient.RequestAdapter.ConvertToNativeRequestAsync<HttpRequestMessage>(requestInformation); // this will be authenticated with the authenticationprovider




            var response = nativeResponseHadnler.Value as HttpResponseMessage;
            if (response.IsSuccessStatusCode)
            {
                string result = response.Content.ReadAsStringAsync().Result;
            }

But it's not fetching any results , content is null.
I am using Request Adapter which was Replaced by HTTProvider.
Please let me know how can i execute this api call using graph client

Thanks

Hi PJ,

Noticed your post, had similar problem, just need to use the client to get the data.

var requestInformation = new RequestInformation()
{
	HttpMethod = Method.GET,
	URI = new Uri("https://tenant.sharepoint.com/sites/SiteInfi2022/_api/web/lists/getbytitle('hen')/items(1)?$expand=AttachmentFiles")
};

// not sure if you need this?
requestInformation.Headers.Add("Accept", "application/xml");
requestInformation.Headers.Add("Content-Type", "application/xml");
requestInformation.Headers.Add("Prefer", "HonorNonIndexedQueriesWarningMayFailRandomly");
        
var httpRequestMessage = GraphClient.RequestAdapter.ConvertToNativeRequestAsync<HttpRequestMessage>(requestInformation);

using HttpClient httpClient = new();
HttpResponseMessage httpResponse = httpClient.Send(httpRequest);
httpResponse.EnsureSuccessStatusCode();
return await httpResponse.Content.ReadAsByteArrayAsync();

HI @Parth Jani,

Thanks for letting us know your user experience. According to your case description, I do understand how frustrated you are now.

Graph sdk can only be used for verification of Graph API, theoretically it cannot verify Sharepoint rest API.

Maybe you can try CSOM to call Sharepoint rest api, or power shell

Sharepoint api :https://www.codesharepoint.com/rest-api/get-all-attachments-from-list-item-in-sharepoint-using-rest-api

CSOM :https://www.codesharepoint.com/csom/get-all-attachments-from-list-item-in-sharepoint-using-csom
