2. 内置多维度的报警(支持 钉钉、企业微信、邮箱)

3. 简单易用,内置三种爬虫,可应对各种需求场景

  • AirSpider 轻量爬虫:学习成本低,可快速上手

  • Spider 分布式爬虫:支持断点续爬、爬虫报警、数据自动入库等功能

  • BatchSpider 批次爬虫:可周期性的采集数据,自动将数据按照指定的采集周期划分。(如每7天全量更新一次商品销量的需求)

feapder对外暴露的接口类似scrapy,可由scrapy快速迁移过来。支持断点续爬数据防丢监控报警浏览器渲染下载海量数据去重等功能

小试一下

创建爬虫

feapder create -s first_spider

创建后的爬虫代码如下:

import feapder


class FirstSpider(feapder.AirSpider):
    def start_requests(self):
        yield feapder.Request("https://www.baidu.com")

    def parse(self, request, response):
        print(response)


if __name__ == "__main__":
    FirstSpider().start()
        

直接运行,打印如下:

Thread-2|2021-02-09 14:55:11,373|request.py|get_response|line:283|DEBUG|
                -------------- FirstSpider.parse request for ----------------
                url  = https://www.baidu.com
                method = GET
                body = {'timeout': 22, 'stream': True, 'verify': False, 'headers': {'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/27.0.1453.93 Safari/537.36'}}

<Response [200]>
Thread-2|2021-02-09 14:55:11,610|parser_control.py|run|line:415|DEBUG| parser 等待任务...
FirstSpider|2021-02-09 14:55:14,620|air_spider.py|run|line:80|INFO| 无任务,爬虫结束

代码解释如下:

  1. start_requests: 生产任务
  2. parse: 解析数据
