Question

非常新且经验丰富。我试图从这个URL中删除每个程序名称： https://www.f6s.com/programs?type[]=accelerator&sort=open

当我运行我的scrapy程序时，我一直得到：

2018-05-15 14:26:05 [scrapy.extensions.logstats]信息：抓0页（每分钟0页），抓0件（0件/分）

我的项目目录：

myproject/

    scrapy.cfg           

    __init__.py

    items.py          

    pipelines.py      

    settings.py       

    spiders/         
        __init__.py
          byub.py
          F6sSpider.py

我的蜘蛛文件：

import scrapy

class CompanySpider(scrapy.Spider):
    name = "Company"

    def start_requests(self):
        urls = [
            'https://www.f6s.com/programs?type[]=accelerator&sort=open',
        ]
        for url in urls:
            yield scrapy.Request(url=url, callback=self.parse)

    def parse(self, response):
        for title in response.css('div.title'):
            yield {
                'program': title.css('div.title a.action.main.no.line::text').extract(),
            }

我希望我的终端输出有'Program'：'Program Name' 任何帮助将不胜感激！

robots.txt错误导致您被禁止，因此只需将以下行添加到settings.py

USER_AGENT = 'Mozilla/5.0 (Windows NT 5.2; rv:10.0.1) Gecko/20100101 Firefox/10.0.1 SeaMonkey/2.7.1' # any browser specific user agent will do
ROBOTSTXT_OBEY=False

scrapy返回0结果
