美团旗下大象商户数据爬虫2-为爬虫绘制GUI并打包 前言公司最近的业务,继上文:https://lisok.cn/python/552.htmlcmd命令的使用有点麻烦,于是学习了一下PyQt5画了一个GUI实现有几个点需要提一下这里的日志输出是给logging添加了拦截器日志内容分成两部分如图,其中store记录的是自己代码中打印的,scrapy.utils.log是scrapy内部记录的一些日志统一添加一个handler处理 回调显示在界面上。store.pyfrom ui.mainwindow import signal class MyCustomHandler(logging.Handler): def __init__(self, signals): super(MyCustomHandler, self).__init__() self.signals = signals def emit(self, record): log_message = self.format(record) # 发送消息到 PyQt 界面 self.signals.log_signal.emit(log_message) class StoreSpider(scrapy.Spider): name = "store" allowed_domains = ["sale-pb.sankuai.com", 'crm.sankuai.com'] start_urls = ["https://sale-pb.sankuai.com/apigw/api/poi/ownership/poi-not-cooperated"] baseinfo_url = 'https://crm.sankuai.com/poi/sales/report/baseinfo?shopId={}' pageSize = 60 pageNum = 1 startCategoryId = 0 startRequest = True infoHeaders = {"Content-Type": "application/json; charset=UTF-8"} custom_settings = { 'LOG_LEVEL': 'INFO', 'LOG_FILE': 'sankuai-cus.log', } def __init__(self, *args, **kwargs): log_names = ['store', 'scrapy.utils.log', 'scrapy.extensions.logstats'] # 'scrapy.addons', 'scrapy.extensions.telnet', 'scrapy.middleware', # 'scrapy.crawler', 'scrapy.core.engine', for log_name in log_names: logging.getLogger(log_name).addHandler(MyCustomHandler(signal)) super().__init__(*args, **kwargs) # 设置Cookie self.cookies = kwargs.get('cookies', []) self.crawl_cities_ids = kwargs.get('crawl_cities_ids', []) # ....mainwindow.pyfrom PyQt5.QtCore import QThread, pyqtSignal, QObject from .ui_main_window.ui_mainwindow import Ui_MainWindow cities = [] class MySignal(QObject): log_signal = pyqtSignal(str) signal = MySignal() cookies = [] crawl_cities_ids = [] # ...其他的代码都很常规,打个包记录一下{cloud title="美团-大象商户爬虫.zip" type="bd" url="/我的分享/美团-大象商户爬虫.zip" password=""/}引用1.python scrapy框架 日志文件:https://blog.csdn.net/weixin_45459224/article/details/1001425372.[Python自学] PyQT5-子线程更新UI数据、信号槽自动绑定、lambda传参、partial传参、覆盖槽函数:https://www.cnblogs.com/leokale-zz/p/13131953.html3.[ PyQt入门教程 ] PyQt5中多线程模块QThread使用方法:https://www.cnblogs.com/linyfeng/p/12239856.html4.Scrapy Logging:https://docs.scrapy.org/en/latest/topics/logging.html#logging-configuration5.在线程中启动scrapy以及多次启动scrapy报错的解决方案(ERROR:root:signal only works in main thread):https://blog.csdn.net/Pual_wang/article/details/106466017
