For the examples used in the following spiders, we'll assume you have a. BaseItemExporter (class in scrapy.exporters) BaseSettings (class in scrapy.settings) bench command; bindaddress reqmeta; body (scrapy.http.Request attribute) (scrapy.http.Response attribute) body_as_unicode() (scrapy.http.TextResponse method) BOT_NAME settin

sitemap_rules:元组列表,包含正则表达式和回调函数,格式是这样的 (regex,callback)。regex 可以是正则表达式,也可以是一个字符串。 callback 用于处理 url 的回调函数; sitemap_follow:指定需要跟进 Sitemap 的正则表达式列表; sitemap_alternate_link:当指定的 url 有可选的链接时是否跟进,默认不跟进。这里. 使用 scrapy.log.msg() 方法记录(log)message。 log中自动带上该spider的 name 属性。 更多数据请参见 Logging 。 封装了通过Spiders的 logger 来发送log消息的方法,并且保持了向后兼容性。 更多内容请参考 Logging from Spiders. closed (reason) ¶. 当spider关闭时,该函数被调用。 该方法提供了一个替代调用signals.connect()来.

Did Scrapy steal X from Django? Does Scrapy work with HTTP proxies? How can I scrape an item with attributes in different pages? Scrapy crashes with: ImportError: No module named win32api; How can I simulate a user in my spider? Does Scrapy crawl in breadth-first or depth-first order? My Scrapy crawler has memory leaks. What can I do scrapy.Spider¶ class scrapy.spiders.Spider¶ This is the simplest spider, and the one from which every other spider must inherit (including spiders that come bundled with Scrapy, as well as spiders that you write yourself). It doesn't provide any special functionality
