python - download and save images from a website using scrapy -


i new scrapy , python, question may simple one. using existing website guide, i've written scraper scrapes website's pages , shows images url, name , ... in output file. want download images in directory output directory empty!

here code:

myspider.py

import scrapy class bricksetspider(scrapy.spider): name = 'brick_spider`enter code here`' start_urls = ['http://brickset.com/sets/year-2016']  def parse(self, response):     set_selector = '.set'     brickset in response.css(set_selector):          name_selector = 'h1 ::text'         pieces_selector = './/dl[dt/text() = "pieces"]/dd/a/text()'         minifigs_selector = './/dl[dt/text() = "minifigs"]/dd[2]/a/text()'         image_selector = 'img ::attr(src)'         yield {             'name': brickset.css(name_selector).extract_first(),             'pieces': brickset.xpath(pieces_selector).extract_first(),             'minifigs': brickset.xpath(minifigs_selector).extract_first(),             'image': brickset.css(image_selector).extract_first(),         }      next_page_selector = '.next ::attr(href)'     next_page = response.css(next_page_selector).extract_first()     if next_page:         yield scrapy.request(             response.urljoin(next_page),             callback=self.parse         )

settings.py

item_pipelines = {'brickset.pipelines.bricksetpipeline': 1} images_store = '/home/nmd/brickset/brickset/spiders/output'   #items.py  import scrapy class bricksetspider(scrapy.item): image_urls = scrapy.field() images = scrapy.field() pass

scrapy provides media pipeline if interested in downloading files or images

item_pipelines = {'scrapy.pipelines.images.imagespipeline': 1}

then need add image_urls in item pipeline download file, change

    yield {         'name': brickset.css(name_selector).extract_first(),         'pieces': brickset.xpath(pieces_selector).extract_first(),         'minifigs': brickset.xpath(minifigs_selector).extract_first(),         'image': brickset.css(image_selector).extract_first(),     }

to

    yield {         'name': brickset.css(name_selector).extract_first(),         'pieces': brickset.xpath(pieces_selector).extract_first(),         'minifigs': brickset.xpath(minifigs_selector).extract_first(),         'image_urls': brickset.css(image_selector).extract_first(),     }

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
