            try:
                username = db.query(Users).filter_by(username=username).first()
                username.nickname = Hnickname		#修改暱稱
                username.img_url = Himg_url			#修改頭像
                db.commit()							# 提交即保存到數據庫
                db.close()							# 關閉會話	
            except:
                db.close()
