How to send item picture to SOAP web service?

(0) ShareShare
ReportReport
Posted on by Morten Steengaard 555

Hi experts,

I need to create a SOAP web service codeunit that gets an item number and returns the picture that is on that item in Business Central cloud.

(I think there can be more that one picture, but I only want to get the first picture.)

I have made the procedure below on a codeunit, but it doesn't return anything.

What am I doing wrong?

    procedure GetItemImage(itemNo: Code[20]) Result: Text

    var
        Item: Record Item;
        TenantMedia: Record "Tenant Media";
        TempBlob: Codeunit "Temp Blob";
        PictureInStream: InStream;
        PictureOutStream: OutStream;
    begin
        if Item.Get(itemNo) then begin
            if Item.Picture.Count = 0 then begin
                exit('');
            end;

            TenantMedia.Get(Item.Picture.Item(1));
            TenantMedia.CalcFields(Content);
            if TenantMedia.Content.HasValue then begin
                Result := '';
                Clear(PictureInStream);
                TenantMedia.Content.CreateInStream(PictureInStream);
                TempBlob.CreateOutStream(PictureOutStream);
                CopyStream(PictureOutStream, PictureInStream);

                PictureInStream.ReadText(Result);
            end;
        end;
    end;

    Hi NorthW,

    I got the streams mixed up. And it seems like I need to add a "true" to the call to "ToBase64" function. I only need to write this code to get it right:

    if TenantMedia.Content.HasValue then begin

       TenantMedia.Content.CreateInStream(PictureInStream);

       Result := base64cnv.ToBase64(PictureInStream, true);

    end;

    Thank you for your time.

    Best regards,

    Morten

    I assume you are 100% sure the item you are trying to export actually got a picture?

    Maybe you can try to add another text to your result so you can see that your WS actually return something at all?

    if Item.Picture.Count = 0 then begin

                   exit('NoPicture');

    Might be one step

    Hi NorthW,

    Thank you for your reply.

    I have changed my code (made one new line and outcommented another), but it still returns blank.

    if TenantMedia.Content.HasValue then begin

       Result := '';

       Clear(PictureInStream);

       TenantMedia.Content.CreateInStream(PictureInStream);

       TempBlob.CreateOutStream(PictureOutStream);

       CopyStream(PictureOutStream, PictureInStream);

       Result := Base64Convert.ToBase64(PictureInStream);

       //PictureInStream.ReadText(Result);

    end;

    If you want to return the picture as part of your soap ws response i think you have to start by base64 encoding the picture stream. The is a codeunit called base64 convert that can do that for you.
