debug_scrapy

This repository is about how to debug scrapy core source code and read it .

(注:此repo是从scrapy源码中抽离出来的scrapy目录,并对大多数代码做了翻译解读,仅供阅读参考,如果有不正确的地方欢迎讨论。小弟翻译不容易,可否给我个小star,让我更有动力去完善它。谢谢!)

1. Get the code:

git clone https://github.com/wangrenlei/debug_scrapy.git

2. Setup the environment

>   python_requires='>=2.7, !=3.0.*, !=3.1.*, !=3.2.*, !=3.3.*',
    install_requires=[
    'Twisted>=13.1.0',
    'w3lib>=1.17.0',
    'queuelib',
    'lxml',
    'pyOpenSSL',
    'cssselect>=0.9',
    'six>=1.5.2',
    'parsel>=1.4',
    'PyDispatcher>=2.0.5',
    'service_identity']</br>

(注:可能环境中的依赖不够完全,那么就在项目运行中根据情况自行添加吧,年纪大了实在是忘了当时候可能装过啥)

3. Run the application:

  • python __main__.py or python cmdline.py

(注:这里默认使用IDE的debug调试,入口处写了所有指令的主要使用方式,根据实际调试情况自行进行注释或释放)

4. Other helps:
