Gohi Cyriac had restored the hosts’ lead just four minutes from time, after earlier goals from Aluko and Craig Conway, only for Lucas Joao to sweep home in the 94th minute.
Fulham subsequently missed the chance to move into the Championship play-off places, sitting one point behind sixth-placed Sheffield Wednesday.
Aluko now wants Fulham to respond to that disappointment when they play Wolves.
“You have got to just take it on the chin,” he said.
“Confidence is still high and four points from our last two games is not terrible. It is not drastic so we will go again and we are still confident that we will make the play-offs.
"We would have taken it a few weeks ago.
Aluko expects a difficult test against Wolves, who are fighting for survival but have recorded back-to-back wins over Rotherham and Brentford.
He continued: “All the teams down there are scrapping for their lives,” he said. “So we have got to be wary.”
