问题是您试图使用不同的值重新运行同一个spider。CrawlerProcess的工作方式是初始化进程，然后需要调度所有计划在进程中运行的spider，然后运行process.start()。
在代码中，在for循环的每次迭代结束时都会调用crawler.start()，但当for循环到达第二次调用时，React器已经关闭，无法重新启动。
因此，您面临的问题是，您希望对所有不同的通道使用相同的spider类，因此，一个可能的解决方案是在返回class对象的函数作用域中定义TestSpider，因此，每次调用该函数时，它将返回相同的TestSpider类，但类对象是唯一的。因此您可以为每个变量分配不同唯一start_urls集。
然后，您可以在for循环中使用CrawlerProcess调度所有不同的TestSpider类对象，然后在for循环完成后运行process.start。
例如，它可能看起来像这样：
