我正在尝试在reclameaqui站点(www.reclameaqui.com.br)上进行网页抓取。代码已经完成,但我无法在lista-reclamacoes/?pagina=1、lista-reclamacoes/?pagina=2、lista-reclamacoes/?pagina=3上进行迭代并获取其内容:

complaintItem['solved'] = self.get_data(data, "props.pageProps.complaint.solved")

complaintItem['url'] = response.url
content_container = response.xpath('//*[contains(@data-testid, "complaint-content-container")]//text()').extract()
complaintItem['tags'] = content_container[content_container.index("ID:") + 2 : content_container.index("Status da reclamação:")]
complaintItem['status'] = response.xpath('//*[contains(@data-testid, "complaint-status")]//text()').extract()
complaintItem['userCity'] = self.get_data(data, "props.pageProps.complaint.userCity")
complaintItem['userState'] = self.get_data(data, "props.pageProps.complaint.userState")
complaintItem['creation_date'] = self.get_data(data, "props.pageProps.complaint.created")
#Interactions contain customer and company replicas.
complaintItem['deal_again'] = self.get_data(data, "props.pageProps.complaint.dealAgain")
complaintItem['score'] = self.get_data(data, "props.pageProps.complaint.score")
yield complaintItem
我得到的是lista-reclamacoes/?pagina=1的内容的三倍(reppetead/similar)。它应该得到lista-reclamacoes/?pagina=1、lista-reclamacoes/?pagina=2、lista-reclamacoes/?pagina=3的所有内容)。
我哪里错了?
