我试着把scravyd和scrappy连用。
当我使用下面的代码时,它工作正常。
import scrapy
from scrapy.selector import Selector
from scrapy.spiders import CrawlSpider
from shikari.items import shikariItem
from scrapy.http import Request
class Radiate(scrapy.Spider) :
name = "run"
allowed_domains = ["google.com"]
start_urls = ['http://google.com']
def parse(self, response) :
item = shikariItem ()
sel = Selector (response)
item['url'] = response.url
return item
但当我把它和 selenium 一起使用时,它就不会
import scrapy
from pyvirtualdisplay import Display
from selenium import webdriver
from shikari.items import shikariItem
class Radiate(scrapy.Spider) :
name = "run"
allowed_domains = ["google.com"]
start_urls = ['http://google.com']
def __init__(self):
display = Display(visible=0, size=(800, 600))
display.start()
self.driver = webdriver.Chrome('/usr/bin/chromedriver')
def parse(self, response) :
item = shikariItem ()
item['url'] = self.driver.get(response.url)
return item
def teardown(self):
display.stop()
self.driver.close()
我的蜘蛛从来没有运行过。在作业中,它被列在“已完成”下,在错误日志中,我看到exceptions.TypeError: __init__() got an unexpected keyword argument '_job'
。
下面是完整的错误日志

我需要做什么才不会收到错误?

您在子类中重新定义了
__init__
,并将其签名从scrapy.Spider
更改为scrapy.Spider
,也没有调用scrapy.Spider
的__init__
方法。scrapy.Spider
源代码zphenhs42#
你的init方法中没有任何参数,只需添加args*和***kwargs***。
