Icrawler is a mini framework of web crawlers. With modularization design, it is easy to use and extend. It supports media data like images and videos very well, and can also be applied to texts and other type of files. Scrapy is heavy and powerful, while icrawler is tiny and flexible. With this package, you can write a multiple thread crawler easily by focusing on the contents you want to crawl, keeping away from troublesome problems like exception handling, thread scheduling and communication. A crawler consists of 3 main components (Feeder, Parser and Downloader), they are connected with each other with FIFO queues. Feeder, parser and downloader are all thread pools, so you can specify the number of threads they use. The package work as follows :
- url_queue stores the url of pages which may contain images
- task_queue stores the image url as well as any meta data you like, each element in the queue is a dictionary and must contain the field img_url
- Feeder puts page urls to url_queue
- Parser requests and parses the page, then extracts the image urls and puts them into task_queue
- Downloader gets tasks from task_queue and requests the images, then saves them in the given path.
