苏宁爬虫

苏宁scrapy爬虫,依据搜索引擎实现指定商品爬虫并将商品参数与评论下载入库。

依赖

scrapy
redis
mongodb
pyqt5

使用

$ git clone ssh://[email protected]:10022/bujue/suning.git
$ cd suning
$ python start.py

分布式爬虫配置

在suning/suning/settings.py中

注:本次项目没有使用代理ip,若要使用,只需修改suninh/suninh/settings.py中

DOWNLOADER_MIDDLEWARES = {
#    'cnblogs.middlewares.MyCustomDownloaderMiddleware': 543,
    'suninh.middlewares.RandomUserAgent': 1, #随机user agent
    #'scrapy.downloadermiddlewares.httpproxy.HttpProxyMiddleware': 110, #代理需要用到
    #'suninh.middlewares.ProxyMiddleware': 100, #代理需要用到
}

修改为

DOWNLOADER_MIDDLEWARES = {
#    'cnblogs.middlewares.MyCustomDownloaderMiddleware': 543,
    'suninh.middlewares.RandomUserAgent': 1, #随机user agent
    'scrapy.downloadermiddlewares.httpproxy.HttpProxyMiddleware': 110, #代理需要用到
    'suninh.middlewares.ProxyMiddleware': 100, #代理需要用到
}

并在suninh/suninh/settings.py中 #代理ip

PROXIES = [
	
	{'ip_port':'117.93.132.94:8998','user_pass':''},
	
]

中加入有效代理ip即可
