如何在Scrapy中下载图像而不出错？

Question

我是个新手。我正在尝试下载一个图像。你知道吗

import scrapy
from scrapy.http import Request


class PlayerSpider(scrapy.Spider):
name = 'player'
#allowed_domains = ['nba.com/players']
start_urls = ['http://www.nba.com/players/']

def parse(self, response):
    Player_Name = response.css('div#content.nba-player-index a ::attr(title)').extract()
    Player_link = response.css('.nba-player-index__trending-item a::attr(href)').extract()
    links  = [url for url in Player_link if url.startswith("/players")]
    for link in links:

        absolute_url = response.urljoin(link)
        yield Request(absolute_url, callback=self.parse_players)

def parse_players(self, response):
    Player_Name = response.css('section.nba-player-header__details-bottom ::text').extract()
    items=[]
    for images in Player_Name:
        item = PlayerSpider()
        images_link = response.css('section.nba-detail-header-wrapper .nba-player-header__headshot img::attr(src)').extract_first()
        image_urls = 'http:{}'.format(images_link)
        item[image_urls]
        return item

    Player_Height = response.css('section.nba-player-vitals__top-left.small-6 p.nba-player-vitals__top-info-imperial ::text').extract()
    Player_Weight = response.css('section.nba-player-vitals__top-right.small-6 p.nba-player-vitals__top-info-imperial ::text').extract()
    yield {
                'Player_name' : Player_Name,
                'Player_Height' : Player_Height,
                'Player Weight' : Player_Weight
        }

我觉得档案很好。但我不能写正确的蜘蛛获得图像。我可以抓取图像的网址，但不知道如何存储图像使用imagePipeline。你知道吗

items.py

import scrapy
from scrapy.item import Item

class PlayerSpider(scrapy.Item):
   image_url = scrapy.Field()
   images = scrapy.Field()
   pass

Answer 1

要启用图像管道，必须首先将其添加到项目项设置中。你知道吗

你知道吗设置.py地址：

ITEM_PIPELINES = {'scrapy.pipelines.images.ImagesPipeline': 1}
IMAGES_STORE = 'images'
