我尝试开始scrapy后，做了一些其他的事情在我的主要。后，解析一些数据，我有网址，并希望将他们首先传递给scrapy，然后开始的过程。
主要的

urls = {'start_urls': ['google.com']}

        spider = LiveSpider(None,**urls)
        #spider.run()
        process = CrawlerProcess(LiveSpider)
        process.crawl(spider)
        process.start()

零碎的实施

class LiveSpider(scrapy.Spider):

    name = 'live'
    allowed_domains = ['google.com']
    #start_urls = []

    def __init__(self, category=None, *args,**kwargs):
        super(LiveSpider, self).__init__(*args,**kwargs)
        self.start_urls = kwargs.get('start_urls')
        for url in self.start_urls:
            print('urls: ' + url)
        print('Urls done')

    def parse(self, response):
        res = response.text

日志

urls: google.com
Urls done
Traceback (most recent call last):

在运行了几个测试之后，这就是解决方案。将start_urls添加到爬网调用中。
根本不需要init函数
主要


# Define urls list before

process = CrawlerProcess()
process.crawl(LiveSpider, start_urls=product_urls)
process.start(stop_after_crawl=False)

刮擦工具
职业活蜘蛛（战斗蜘蛛）：

name = 'live'
allowed_domains = ['google.com']
start_urls = []

def parse(self, response):
    res = response.text
    #Do some parsing
