这是settings.py
文件中的图像管道设置
进程停止后,我去检查图像是否下载在给定的目录中,但文件夹是空的。 有人请看一下。在
以下是主要的蜘蛛代码供参考
import scrapy
import FourChan.items as items
class DmozSpider(scrapy.Spider):
name = "imageSpider"
allowed_domains = ["4chan.org"]
# thread = raw_input("Enter thread link: ")
start_urls = [
# thread
"http://boards.4chan.org/a/thread/136492097/would-you-still-stay-with-you-waifu-if-she-was",
]
def parse(self, response):
page = response
item = items.FourchanItem()
testCss = page.selector.css('.fileThumb::attr(href)').extract()
for test in testCss:
url = "http:"+test
# url = test[2:]
filename = url.split("/")[-1]
# print filename
item['fileName'] = filename
item['image_urls'] = [url] #This needs to be a list, in order for the image pipeline to work, can't be a string
yield item
这真是太傻了,错在
IMAGES_STORE = '/Work/ScrapyTests/FourChan/FourChan/downloads/'
应该是
IMAGES_STORE = 'Work/ScrapyTests/FourChan/FourChan/downloads/'
不需要起始正斜杠。在
