Scrapy uses the Twisted asynchronous network library to handle network traffic.The overall structure is broadly as follows (note: Images from the Internet):1. Scrapy engine (Scrapy engines)The Scrapy engine is used to control the data processing flow of the entire system and to trigger transactions. More detailed information can be found in the following data processing process.2, Scheduler (Dispatch)The scheduler accepts requests from the Scrapy engine and sorts them into queues and returns the

1, overview Scrapy is an application framework written with pure Python for crawling Web site data and extracting structural data, which is very versatile. The power of the framework, users only need to customize the development of a few modules can be easily implemented a crawler, used to crawl Web content and a variety of pictures, very convenient. Scrapy uses the twisted[' tw?st?d] (its main opponent is Tornado), the asynchronous network framework to handle network traffic, c

These special needs tell us that the above code is completely out of the way. So for the completeness and scalability of the control, we need a configurator, a monitor, a downloader. And so on special needs to add the plug-in development. Therefore, we can see that under the Org.kymjs.aframe.bi

It looks like the spider is preparing itself, so you can guess that the Scrapy architecture section (not including the spider) mainly does event scheduling, regardless of the URL's storage. Looks like the Gooseeker member center of the crawler Compass, for the target site to prepare a batch of URLs, placed in the compass ready to perform crawler operation. So, the next goal of this open source project is to put the URL management in a centralized disp
