搜索进程似乎忽略和/或不执行yield scrapy.Request(property_file, callback=self.parse_property)行。def start_requests中的第一个scrapy.Request正确通过并执行，但def parse_navpage中的一个请求却不正确，如图所示。

import scrapy

class SmartproxySpider(scrapy.Spider):
    name = "scrape_zoopla"
    allowed_domains = ['zoopla.co.uk']

    def start_requests(self):
        # Read source from file
        navpage_file = f"file:///C:/Users/user/PycharmProjects/ScrapeZoopla/ScrapeZoopla/ScrapeZoopla/spiders/html_source/navpage/NavPage_1.html"
        yield scrapy.Request(navpage_file, callback=self.parse_navpage)

    def parse_navpage(self, response):
        listings = response.xpath("//div[starts-with(@data-testid, 'search-result_listing_')]")

        for listing in listings:
            listing_url = listing.xpath(
                "//a[@data-testid='listing-details-link']/@href").getall()  # List of property urls
            break
        print(listing_url) #Works

        property_file = f"file:///C:/Users/user/PycharmProjects/ScrapeZoopla/ScrapeZoopla/ScrapeZoopla/spiders/html_source/properties/Property_1.html"
        print("BEFORE YIELD")
        yield scrapy.Request(property_file, callback=self.parse_property) #Not going through
        print("AFTER YIELD")

    def parse_property(self, response):
        print("PARSE PROPERTY")
        print(response.url)
        print("PARSE PROPERTY AFTER URL")

在命令中运行scrapy crawl scrape_zoopla将返回：

两个都不好。请求请求本地文件，只有第一个工作。文件存在并正确显示页面，如果其中一个文件不存在，爬行器将返回错误“没有这样的文件或目录”，并可能被中断。在这里，爬行器似乎只是通过了请求，甚至没有通过它，并没有返回错误。这里的错误是什么？
