我是scrapy的初学者，我想在函数process_request中打印一些东西，但问题是在查看scrapy的日志时看不到它
middlewares.py > process_request内的代码

referr = random.choice(refreerr_list)
        print(referr)
        request.header['rtt'] = random.choice(rtt)
        request.header['sec-ch-viewport-width'] = random.choice(width_list)
        request.header['sec-ch-device-memory'] = random.choice(memory_list)
        request.header['device-memory'] = random.choice(memory_list)
        request.header['referer'] = referr
        request.header['cookie'] = 'sessi...'

        print(self._requests_count)

        self._requests_count += 1
        if self._requests_count > 500:
            self._requests_count = 0
            ip_changer.get_new_ip()

        print(f"thitshtisih {self._requests_count}")

由于这我正在搜索thitshtisih，但我不能看到在终端日志。
我也试过这个spider.logger.info('Requestingsssssss %...，但在代码中没有找到相同的
以下是日志的外观：
