scrapy_redis 的问题!!!

    from scrapy_redis import spiders
    import scrapy

    class TestSpider(spiders.RedisSpider):
    name = 'test'
    redis_key = 'a'

    def parse(self, response):
    for i in range(10):
    yield scrapy.Request(url='https://www.baidu.com', dont_filter=True, callback=self.login)

    def login(self, response):
    print(1)


    请问为什么这样写运行的时候只会产生了一个请求?是因为 redis 的 requests 队列去重了吗,这么取消去重?
