我已经根据docs安装并设置了scrapy-splash。我的蜘蛛看起来像这样：
import scrapy
from testencode.items import TestencodeItem
from scrapy_splash import SplashRequest
class Test1Spider(scrapy.Spider):
name = 'test1'
allowed_domains = ['lg.com']
def start_requests(self):
yield SplashRequest(
url = 'https://www.lg.com/it',
callback=self.parse,
)
def parse(self, response):
i = TestencodeItem()
i['title'] = response.xpath('//head/title//text()').extract_first()
return i
我激活了启动图像（在端口8050上），并且我的浏览器可以访问127.0.0.1/8050。但是当我运行Spider时，它抛出一个错误，说它无法连接到端口6800（即scrapyd端口）。

我试图通过激活scrapyd解决它。但是，所有这些操作都是在激活蜘蛛网后使cmd窗口冻结。我有点不解，因为官方文档中没有提到需要使用scrapyd来使用启动程序，而且在与启动程序相关的设置中我没有引用端口6800。
