Uploading a bitmap with idHTTP from a Delphi 10.3 multidevice app - http

Question

I have read many related posts about sending data with idHTTP but still I can't manage it.
I use this code :
updated
procedure TTabbedForm.SpeedButton1Click(Sender: TObject);
var
fName : string;
mStream : TMemoryStream;
begin
fName := 'image.jpg';
mStream := TMemoryStream.Create;
myImage.Bitmap.SaveToStream(mStream);
mStream.Position := 0;
try
IdHTTP1.Request.ContentType := 'application/octet-stream';
IdHTTP1.PUT('http://www.example.com/'+fName, mStream);
finally
mStream.free;
end;
end;
but i receive the error "Method not allowed".
What i'm doing wrong, please ?

For uploads to Google Drive, some additional steps are required. For example, the HTTP POST request must include a auth token which in turn is provided to you only after authentication (log in with a Google account). For Google Drive you must also use secure connections (https) which require SSL libraries such as OpenSSL.
Example from the API docs:
POST https://www.googleapis.com/upload/drive/v3/files?uploadType=media HTTP/1.1
Content-Type: image/jpeg
Content-Length: [NUMBER_OF_BYTES_IN_FILE]
Authorization: Bearer [YOUR_AUTH_TOKEN]
[JPEG_DATA]
The file simple upload API for Google Drive is documented here:
https://developers.google.com/drive/api/v3/simple-upload
Update
Try this example, it requires a valid auth token:
procedure TDriveAPITest.Run;
var
PostData: TStream;
Response: string;
begin
PostData := TFileStream.Create('test.png', fmOpenRead or fmShareDenyWrite);
try
IdHTTP := TIdHTTP.Create;
try
IdHTTP.HTTPOptions := IdHTTP.HTTPOptions + [hoNoProtocolErrorException];
IdHTTP.Request.CustomHeaders.Values['Authorization'] := 'Bearer [YOUR_AUTH_TOKEN]';
Response := IdHTTP.Post('https://www.googleapis.com/upload/drive/v3/files?uploadType=media', PostData);
if IdHTTP.ResponseCode = 200 then begin
WriteLn('Response: ' + Response);
end else begin
WriteLn('Error: ' + IdHTTP.ResponseText);
end;
finally
IdHTTP.Free;
end;
finally
PostData.Free;
end;
end;
Output:
Error: HTTP/1.0 401 Unauthorized
