scrapy-inline-requests 0.3.0

Usage

The spider below shows a simple use case of scraping a page and following a few links:

from scrapy import Spider, Request
from inline_requests import inline_requests

class MySpider(Spider):
    name = 'myspider'
    start_urls = ['http://httpbin.org/html']

    @inline_requests
    def parse(self, response):
        urls = [response.url]
        for i in range(10):
            next_resp = yield Request(response.urljoin('?page=%d' % i))
            urls.append(next_resp.url)
        yield {'urls': urls}

See the examples/ directory for a more complex spider.

Known Issues

• Middlewares can drop or ignore non-200 status responses causing the callback to not continue its execution. This can be overcome by using the flag handle_httpstatus_all. See the httperror middleware documentation.

• High concurrency and large responses can cause higher memory usage.

• This decorator assumes your method have the following signature (self, response).

• The decorated method must return a generator instance.
