Scrapy 抓取简书专题下的文章

可以开一个定时任务,每天抓取自己感兴趣的相关文章,集中起来进行阅读。平时看简书的 程序员 专题比较多,先从这个开始。

安装 Python

一般 Linux 或者 Mac OS 都会自带 python 环境

安装 virtualenv

pippython 下的包管理工具。一般安装 python 后会自带 pip, 或者可以通过 brew 安装。
然后通过 pip 安装 python 虚拟环境:virtualenv

注:OS X 10.11 安装 Scrapy 有问题,所以借助 virtualenv

# 安装 virtualenv
$ pip install virtualenv
# 创建一个虚拟环境,名称为 venv
$ virtualenv venv

安装 Scrapy

爬虫的主要模块,更多详细文档可以查看Scrapy 1.0 官网

$ pip install scrapy

分析网页结构

有了基础的准备,可以开始爬虫了,首先需要分析网页结构,找到自己需要的信息。

运行: scrapy runspider jianshu_spider.py,输出如下结果:
