Question

from scrapy_selenium import SeleniumRequest
import scrapy
from selenium import webdriver
class testspider1(scrapy.Spider):
    driver=webdriver.Firefox(executable_path=r"C:\Users\test\Desktop\geckodriver")
    name = 'test5'
    start_urls=['http://httpbin.org/ip']
    def parse(self, response):
        print(response.body)
        url = "https://www.target.com/p/cesar-canine-cuisine-filet-mignon-flavor-wet-dog-food-3-5oz-tray/-/A-14903668"
        yield SeleniumRequest(url=url,callback=self.parse_result)


    def parse_result(self,response):        
        image = response.xpath('//*[@id="mainContainer"]/div/div/div[1]/div[1]/div[2]/div[1]/div/div/div/div/div/div/div/a/div/div/div/div/div/img/@src').extract_first()
        price = response.selector.xpath('//*[@id="mainContainer"]/div/div/div[1]/div[2]/div/div[1]/span/text()').extract_first()
        print(image)
        print("\n\n")
        print(price)

设置文件：

from shutil import which
BOT_NAME = 'seleniumtest'
SPIDER_MODULES = ['seleniumtest.spiders']
NEWSPIDER_MODULE = 'seleniumtest.spiders'
SELENIUM_DRIVER_NAME = 'firefox'
SELENIUM_DRIVER_EXECUTABLE_PATH = which('geckodriver')
SELENIUM_BROWSER_EXECUTABLE_PATH = which(r"C:\Users\test\Desktop\geckodriver")
ROBOTSTXT_OBEY = True
    DOWNLOADER_MIDDLEWARES = {
   'scrapy_selenium.SeleniumMiddleware': 800
}

documentation on scrapy-selenium 我已经按照说明进行了逐步操作，但是驱动程序没有遵循任何链接。我相信这两个请求都是由scrapy处理的。我不想更改__init__，因为我希望通过scrapy（单独）使用scrapy-Selenium处理某些请求。

我检查了passing-selenium-driver-to-scrapy，但它更改了整个init，使硒成为self.driver。

我希望SeleniumRequest的其他请求可以通过抓取Request来处理

注意：我还以该站点为示例网站，该站点使用java显示结果，如果尚未呈现由不完整（单独）数据处理的结果，那么结果将为空列表

我用chrome替换了Firefox：

from webdriver_manager.chrome import ChromeDriverManager
driver = webdriver.Chrome(ChromeDriverManager().install())

scrapy-selenium驱动程序不跟随
