Sending a Word document over HTTP Post in Business Central without OnPrem scope - ms-word

Question

I need to be able to send a Word document over HTTP POST in Business Central. It needs to be sent to an Azure Function that takes in two Word documents.
How would I go about uploading the Word documents to Business Central (I Assume through UploadIntoStream) and then sending the files over HTTP?

Answer 1

You are correct, you need to upload the file into a stream and send it over HTTP. Depending on your azure function you need to either base64 encode it or send it as a binary. This should help you on your way.
The below is mockup code that tells you how to insert an uploaded file into a HTTP request but it does not contain a fully working, authenticated HTTP request. That depends on you Azure Function setup.
procedure SendUploadedFileToAPI() result: JsonObject
var
Base64Convert: Codeunit "Base64 Convert";
Instr: InStream;
jObject: JsonObject;
Client: HttpClient;
Response: HttpResponseMessage;
Content: HttpContent;
ContentHeaders: HttpHeaders;
UploadFilename: Text;
SelectFileLbl: Label 'Select a file';
CannotConnectErr: Label 'Cannot connect';
begin
UploadIntoStream(SelectFileLbl, '', 'All files (*.*)|*.*', UploadFilename, InStr);
// Use a json with base64
jObject.Add('file', Base64Convert.ToBase64(Instr));
Content.WriteFrom(Format(jObject));
Content.GetHeaders(ContentHeaders);
ContentHeaders.Clear();
ContentHeaders.Add('Content-Type', 'application/json');
// Or send as binary
Content.WriteFrom(Instr);
ContentHeaders.Add('Content-Type', 'application/json');
if not Client.Post('url', Content, Response) then
Error(CannotConnectErr);
end;
