Python -- scrapy

@、使用scrapyd、python-scrapyd-api 部署

scrapyd安装:https://cuiqingcai.com/31049.html
python-scrapyd-api安装:https://cuiqingcai.com/31052.html
我的做法
- 使用win10子系统ubuntu
- 在ubuntu中创建虚拟环境,并切换到虚拟环境
- pip3 install scrapyd
- 直接在命令行输入:scrapyd 回车 启动scrapyd
- 回到win10系统,创建一个scrapy项目:scrapy startproject scrapyd_demo
- 进入项目目录:cd scrapyd_demo
- 生成一个spider:scrapy genspider baidu baidu.com
- 在项目目录下创建setup.py文件,注意:这里可能要配置entry_points,否则有可能报错
from setuptools import setup, find_packages setup( name='scrapyd_demo', version='0.0.1', packages=find_packages(), entry_points={'scrapy': ['settings = scrapyd_demo.settings']}, ) ''' 如果不配置entry_points,通过scrapyd-api方法add_version进行部署时可能会出现下面错误 settings_module = d.get_entry_info('scrapy', 'settings').module_name AttributeError: 'NoneType' object has no attribute 'module_name' '''View Code
- 打包成egg https://www.cnblogs.com/yarightok/p/15567642.html
- 在生成的dist目录下创建一个用来部署的文件,比如:scrapyd_api_deploy.py,添加如下代码:
import os from scrapyd_api import ScrapydAPI scrapyd = ScrapydAPI('http://localhost:6800') egg_file = open(f'{os.path.dirname(__file__)}\scrapyd_demo-0.0.1-py3.6.egg', 'rb') scrapyd.add_version('scrapyd_demo', version='0.0.1', egg=egg_file) print('projects: ', scrapyd.list_projects()) print('spiders: ', scrapyd.list_spiders('scrapyd_demo')) ''' 输出结果 projects: ['scrapyd_demo'] spiders: ['baidu'] '''View Code
- 运行上面的文件
- 在浏览器上运行:http://127.0.0.1:6800/listprojects.json
- 返回结果:{"node_name": "DESKTOP-MM3IOUH", "status": "ok", "projects": ["scrapyd_demo"]}
