我写了一个蜘蛛来抓取一个大网站。我把它放在scrapehub上，并且使用了crawlera插件。没有crawlera，我的蜘蛛在scrapehub上运行得很好。只要我切换到crawlera中间件，蜘蛛就退出了，没有做任何抓取。
我在没有crawlera的情况下运行spider，它在我的本地系统和scrapehub上运行，我唯一改变的是为crawlera启用的中间件。
第一个
下面是没有crawlera中间件的相同蜘蛛的日志

我用python写了一个脚本来测试crawlera连接

import requests

response = requests.get(
    "https://www.youtube.com",
    proxies={
        "http": "http://<APIkey>:@proxy.crawlera.com:8010/",
    },
)
print(response.text)

这是可行的，但我不能为我的生活让爬虫工作与crawlera中间件。
我想得到同样的结果使用crawlera bc没有我得到迅速禁止。
请帮帮忙。
