1.pyspider的安装
pip install pyspider
2. 启动pyspider: 输入 pyspider all
但是启动pyspider 经常遇到没法正常启动，阻塞到 result_worker starting… ,感觉应该是源码有bug 存在，不过没关系，重新在开一个窗口，执行一下 pyspider all 就可以了。
3. 在通过浏览器访问：localhost:5000/
进入源码编写界面：查看result结果：
查看数据库存储:
源码可直接运行，先自行在mysql中手动创建表和字段，原本想在代码里链接数据库的时候通过代码创建表和字段，好像有点问题，暂时先注释掉，后续在来看这个问题：
