Thank you for sharing

prerequisite

python 3.6 and scrapy is needed.

commands

run one command to get 50 pages result from search engine with keyword, the result would be kept in the "urls.txt" under the current directory.

####Bing scrapy crawl keywordSpider -a keyword=Spider-Man -a se=bing -a pages=50

####Baidu scrapy crawl keywordSpider -a keyword=Spider-Man -a se=baidu -a pages=50

####Google scrapy crawl keywordSpider -a keyword=Spider-Man -a se=google -a pages=50

limitation

The project doesn't provide any workaround to the anti-spider measure like CAPTCHA, IP ban list, etc.

But to reduce these measures, we recommand to set DOWNLOAD_DELAY=10 in settings.py file to add a temporisation (in second) between the crawl of two pages, see details in Scrapy Setting.

Chinese

本项目用于bing、google、baidu搜索引擎关键词的抓链，基于python 3.6和scrapy。

根据 https://github.com/xtt129/seCrawler 提供的项目进行小小改动以适应3.6版本。

使用方法： ---进入项目目录执行指令---

Bing：

scrapy crawl keywordSpider -a keyword=Spider-Man -a se=bing -a pages=50

Baidu：

scrapy crawl keywordSpider -a keyword=Spider-Man -a se=baidu -a pages=50

Google：

scrapy crawl keywordSpider -a keyword=Spider-Man -a se=google -a pages=50

本项目没有保护IP的功能，过度爬取可能会被封杀IP，可以尝试延长下载时间间隔： 在settings.py中进行配置，例：DOWNLOAD_DELAY=10
