Put Scrapy spiders behind an HTTP API

ScrapyRT (Scrapy realtime)

Add HTTP API for your Scrapy project in minutes.

You send a request to ScrapyRT with spider name and URL, and in response, you get items collected by a spider visiting this URL.

• All Scrapy project components (e.g. middleware, pipelines, extensions) are supported

• You run Scrapyrt in Scrapy project directory. It starts HTTP server allowing you to schedule spiders and get spider output in JSON.

Quickstart

1. install

> pip install scrapyrt

2. switch to Scrapy project (e.g. quotesbot project)

> cd my/project_path/is/quotesbot

3. launch ScrapyRT

> scrapyrt

4. run your spiders

> curl "localhost:9080/crawl.json?spider_name=toscrape-css&url=http://quotes.toscrape.com/"

5. run more complex query, e.g. specify callback for Scrapy request and zipcode argument for spider

>  curl --data '{"request": {"url": "http://quotes.toscrape.com/page/2/", "callback":"some_callback"}, "spider_name": "toscrape-css", "crawl_args": {"zipcode":"14000"}}' http://localhost:9080/crawl.json -v

Scrapyrt will look for scrapy.cfg file to determine your project settings, and will raise error if it won’t find one. Note that you need to have all your project requirements installed.

Note

• Project is not a replacement for Scrapyd or Scrapy Cloud or other infrastructure to run long running crawls

• Not suitable for long running spiders, good for spiders that will fetch one response from some website and return items quickly
