https://github.com/daacheng/PythonBasic/blob/master/studynotes/Python爬虫--scrapy爬虫框架入门.md#一创建一个scrapy爬虫项目
https://github.com/daacheng/PythonBasic/blob/master/pic/scrapy1.png
https://github.com/daacheng/PythonBasic/blob/master/studynotes/Python爬虫--scrapy爬虫框架入门.md#二创建一个spider爬虫类抓取网页内容并解析
https://github.com/daacheng/PythonBasic/blob/master/pic/scrapy2.png
https://github.com/daacheng/PythonBasic/blob/master/studynotes/Python爬虫--scrapy爬虫框架入门.md#三数据模型item定义爬取数据的数据结构
https://github.com/daacheng/PythonBasic/blob/master/studynotes/Python爬虫--scrapy爬虫框架入门.md#四利用item-pipeline存储抓取item将数据存入mongodb
https://github.com/daacheng/PythonBasic/blob/master/studynotes/Python爬虫--scrapy爬虫框架入门.md#首先要在settingpy中添加mongodb数据库连接信息
https://github.com/daacheng/PythonBasic/blob/master/studynotes/Python爬虫--scrapy爬虫框架入门.md#然后在pipelinespy中创建一个类连接数据库进行数据插入
https://github.com/daacheng/PythonBasic/blob/master/studynotes/Python爬虫--scrapy爬虫框架入门.md#最后在settingpy中指定item-pipeline用到的类及优先级
https://github.com/daacheng/PythonBasic/blob/master/studynotes/Python爬虫--scrapy爬虫框架入门.md#运行命令行-scrapy-crawl-爬虫名称name-就可以发现数据成功存入到数据库中了
