痒不爬

Question

我有最后一个问题：last question

现在我已经尽我最大的努力去思考和改进我的蜘蛛的结构。 然而，由于某些原因，我的蜘蛛还是没有开始爬行。在

我还检查了xpath，它们工作正常（在chrome控制台）。在

我用href加入了url，因为href始终只返回参数。我在最后一个问题上附上了一个链接格式示例。（我希望不要让这篇文章变得冗长）

我的蜘蛛：

 class kmssSpider(scrapy.Spider):
    name='kmss'
    start_url = 'https://kmssqkr.hksarg/LotusQuickr/dept/Main.nsf/h_RoomHome/ade682e34fc59d274825770b0037d278/?OpenDocument#{unid=ADE682E34FC59D274825770B0037D278}'
    login_page = 'https://kmssqkr.hksarg/LotusQuickr/dept/Main.nsf?OpenDatabase&Login'
    allowed_domain = ["kmssqkr.hksarg"]

    def start_requests(self):
        yield Request(url=self.login_page, callback=self.login ,dont_filter = True
                )
    def login(self,response):
        return FormRequest.from_response(response,formdata={'user':'usename','password':'pw'},
                                        callback = self.check_login_response)

    def check_login_response(self,response):
        if 'Welcome' in response.body:
            self.log("\n\n\n\n Successfuly Logged in \n\n\n ")
            yield Request(url=self.start_url,
                           cookies={'LtpaToken2':'jHxHvqs+NeT...'}
                                  )
        else:
            self.log("\n\n You are not logged in \n\n " )

    def parse(self,response):
        listattheleft = response.xpath("*//*[@class='qlist']/li[not(contains(@role,'menuitem'))]")
        anyfolder = response.xpath("*//*[@class='q-folderItem']/h4")
        anyfile = response.xpath("*//*[@class='q-otherItem']/h4")
        for each_tab in listattheleft:
            item = CrawlkmssItem()
            item['url'] = each_tab.xpath('a/@href').extract()
            item['title']   = each_tab.xpath('a/text()').extract()
            yield item

            if 'unid' not in each_tab.xpath('./a').extract():
                parameter = each_tab.xpath('a/@href').extract()
                locatetheroom = parameter.find('PageLibrary')
                item['room'] = parameter[locatetheroom:]
                locatethestart = response.url.find('#',0)
                full_url = response.url[:locatethestart] + parameter
                yield Request(url=full_url,
                              cookies={'LtpaToken2':'jHxHvqs+NeT...'}
                                  )

        for folder in anyfolder:
            folderparameter = folder.xpath('a/@href').extract()
            locatethestart = response.url.find('#',0)

            yield Request(url=folder_url, callback='parse_folder',
                          cookies={'LtpaToken2':'jHxHvqs+NeT...'}
                                  )        

        for File in anyfile:
            fileparameter = File.xpath('a/@href').extract()
            locatethestart = response.url.find('#',0)

                                  )  

    def parse_folder(self,response):
        findfolder = response.xpath("//div[@class='lotusHeader']")
        folderitem= CrawlkmssFolder()
        folderitem['foldername'] = findfolder.xpath('h1/span/span/text()').extract()
        folderitem['url']= response.url[response.url.find("unid=")+5:]    
        yield folderitem


    def parse_file(self,response):
        findfile = response.xpath("//div[@class='lotusContent']")
        fileitem = CrawlkmssFile()
        fileitem['filename']=findfile.xpath('a/text()').extract()
        fileitem['title']=findfile.xpath(".//div[@class='qkrTitle']/span/@title").extract()
        fileitem['author']=findfile.xpath(".//div[@class='lotusMeta']/span[3]/span/text()").extract()
        yield fileitem

我觉得你太复杂了，为什么你要做继承自类scrapy.Spider的繁重工作，而你有{a1}？Spider通常用于抓取页面列表，而Crawler用于抓取网站。在

This is the most commonly used spider for crawling regular websites, as it provides a convenient mechanism for following links by defining a set of rules.
