I am new to Scrapy . I am trying to download files using media pipeline. But when I am running spider no files are stored in the folder.
spider:
import scrapy
from scrapy import Request
from pagalworld.items import PagalworldItem
class JobsSpider(scrapy.Spider):
name = "songs"
allowed_domains = ["pagalworld.me"]
start_urls =['https://pagalworld.me/category/11598/Latest%20Bollywood%20Hindi%20Mp3%20Songs%20-%202017.html']
def parse(self, response):
urls = response.xpath('//div[#class="pageLinkList"]/ul/li/a/#href').extract()
for link in urls:
yield Request(link, callback=self.parse_page, )
def parse_page(self, response):
songName=response.xpath('//li/b/a/#href').extract()
for song in songName:
yield Request(song,callback=self.parsing_link)
def parsing_link(self,response):
item= PagalworldItem()
item['file_urls']=response.xpath('//div[#class="menu_row"]/a[#class="touch"]/#href').extract()
yield{"download_link":item['file_urls']}
Item file:
import scrapy
class PagalworldItem(scrapy.Item):
file_urls=scrapy.Field()
Settings File:
BOT_NAME = 'pagalworld'
SPIDER_MODULES = ['pagalworld.spiders']
NEWSPIDER_MODULE = 'pagalworld.spiders'
ROBOTSTXT_OBEY = True
CONCURRENT_REQUESTS = 5
DOWNLOAD_DELAY = 3
ITEM_PIPELINES = {
'scrapy.pipelines.files.FilesPipeline': 1
}
FILES_STORE = '/tmp/media/'
The output looks like this:
def parsing_link(self,response):
item= PagalworldItem()
item['file_urls']=response.xpath('//div[#class="menu_row"]/a[#class="touch"]/#href').extract()
yield{"download_link":item['file_urls']}
You are yielding:
yield {"download_link": ['http://someurl.com']}
where for scrapy's Media/File pipeline to work you need to yield and item that contains file_urls field. So try this instead:
def parsing_link(self,response):
item= PagalworldItem()
item['file_urls']=response.xpath('//div[#class="menu_row"]/a[#class="touch"]/#href').extract()
yield item

I have a problem with my script such that the same file name, and pdf is downloading. I have checked the output of my results without downloadfile and I get unique data. It's when I use the pipeline that it somehow produces duplicates for download.
Here's my script:
import scrapy
from environment.items import fcpItem
class fscSpider(scrapy.Spider):
name = 'fsc'
start_urls = ['https://fsc.org/en/members']

url,
callback = self.parse
)

content = response.xpath("(//div[#class='content__wrapper field field--name-field-content field--type-entity-reference-revisions field--label-hidden field__items']/div[#class='content__item even field__item'])[position() >1]")
loader = fcpItem()
names_add = response.xpath(".//div[#class = 'field__item resource-item']/article//span[#class='media-caption file-caption']/text()").getall()
url = response.xpath(".//div[#class = 'field__item resource-item']/article/div[#class='actions']/a//#href").getall()
pdf=[response.urljoin(x) for x in url if '#' is not x]

I am using css instead of xpath.
From the chrome debug panel, the tag is root of item of PDF list.
Under that div tag has title of PDF and tag for file download URL
Between root tag and tag two child's and sibling relation so xpath is not clean method and hard, a css much better is can easley pick up from root to . it don't necessary relation ship path. css can skip relationship and just sub/or grand sub is not matter. It also provides not necessary to consider index problem which is URL array and title array sync by index match.
Other key point are URL path decoding and file_urls needs to set array type even if single item.

The problem is that you are overwriting the same scrapy item every iteration.
What you need to do is create a new item for each time your parse method yields. I have tested this and confirmed that it does produce the results you desire.
I made and inline not in my example below on the line that needs to be changed.
For example:
import scrapy
from environment.items import fcpItem
class fscSpider(scrapy.Spider):
name = 'fsc'
start_urls = ['https://fsc.org/en/members']
def start_requests(self):
for url in self.start_urls:
yield scrapy.Request(
url,
callback = self.parse
)
def parse(self, response):
content = response.xpath("(//div[#class='content__wrapper field field--name-field-content field--type-entity-reference-revisions field--label-hidden field__items']/div[#class='content__item even field__item'])[position() >1]")
names_add = response.xpath(".//div[#class = 'field__item resource-item']/article//span[#class='media-caption file-caption']/text()").getall()
url = response.xpath(".//div[#class = 'field__item resource-item']/article/div[#class='actions']/a//#href").getall()
pdf=[response.urljoin(x) for x in url if '#' is not x]
names = [x.split(' ')[0] for x in names_add]
for nm, pd in zip(names, pdf):
loader = fcpItem() # Here you create a new item each iteration
loader['names'] = nm
loader['pdfs'] = [pd]
yield loader
I am new to scrapy.I downloaded some files using the code bellow. I want to change the names of my downloaded files but I don't know how.
For example, I want to have a list containing names and use it to rename the files that I downloaded.

How can I scrape all items in all pages?

Change allowed_domains = ['http://www.lapada.org'] to allowed_domains = ['lapada.org']
Scrapy super noob here. Problem: I have an html page that contains both information that I want to scrape and an url that I want to follow to get images urls for images that I want to download and save via the scrapy image pipeline.
My approach to achieve this:
1. Scrape all the details as usual with a parse method
2. Find the url in the initial page, create a request that has a second parse method as callback where I build the image_urls list.
So, I have the following setup:
settings.py
...
ITEM_PIPELINES = {
'crawlbot.pipelines.MybotPipeline': 300,
'scrapy.pipelines.images.ImagesPipeline': 1,
}
IMAGES_STORE = '/url/to/images' #valid path to actual folder
...
pipelines.py
import pymongo
class MybotPipeline(object):
def __init__(self):
self.conn = pymongo.MongoClient('localhost', 27017)
db = self.conn['libraries']
self.collection = db['books']
def process_item(self, item, spider):
self.collection.insert(dict(item))
return item
items.py
import scrapy
class MybotItem(scrapy.Item):
url = scrapy.Field()
title = scrapy.Field()
images = scrapy.Field()
image_urls = scrapy.Field()
description = scrapy.Field()
crawler.py
import scrapy
from scrapy.spiders import CrawlSpider
class MySpider(CrawlSpider):
name = 'myspider'
allowed_domains = ['books.com']
def start_requests(self):
urls = [
'https://www.books.com/some/url'
]
custom_settings = {
'DEPTH_LIMIT': 1
}
for url in urls:
yield scrapy.Request(url=url, callback=self.parse_item)
def parse_details(self, response):
for image in enumerate(response.xpath('//div[contains(#class, "jumbotron")]/div')):
image_urls = image.xpath('div[contains(#class, "jumbotron-image")]/img/#src').getall()
def parse_item(self, response):
for idx, list_item in enumerate(response.xpath('//div[contains(#class, "slider-wrapper")]')):
anchor = list_item.xpath('div[contains(#class, "slider-section")]/div/a')
slider_thumbnail = anchor.xpath('div[contains(#class, "slider-thumbnail")]')
description = slider_thumbnail.xpath('div[contains(#class, "description-box")]')
yield {
'url': anchor.xpath('#href').get(),
'description': description
}
details_page_urls = anchor.xpath('#href').getall()
for details_page in details_page_urls:
yield scrapy.Request(url=details_page, callback=self.parse_details)
This is not working, although with my little knowledge of both Scrapy and Python, the second parse method should return a list of image_urls. So I have 2 questions: 1. is there a better approach for my case? Maybe the whole issue is in trying to do too much with one spider? 2. If the approach is ok, what am I doing wrong?
My spider runs without displaying any errors but the images are not stored in the folder here are my scrapy files:

Since you don't know what to put in the pipelines I assume you can use the default pipeline for images provided by scrapy so in the settings.py file you can just declare it like
ITEM_PIPELINES = {
'scrapy.pipelines.images.ImagesPipeline':1
}
Also, your images path is wrong the / means that you are going to the absolute root path of your machine, so you either put the absolute path to where you want to save or just do a relative path from where you are running your crawler
IMAGES_STORE = '/home/user/Documents/scrapy_project/images'
or
IMAGES_STORE = 'images'
Now, in the spider you extract the url but you don't save it into the item
item['image_urls'] = sel.xpath('//a[#data-tealium-id="detail_nav_showphotos"]/#href').extract_first()
The field has to literally be image_urls if you're using the default pipeline.
Now, in the items.py file you need to add the following 2 fields (both are required with this literal name)
image_urls=Field()
images=Field()
That should work
In my case it was the IMAGES_STORE path that was causing the problem
I did IMAGES_STORE = 'images' and it worked like a charm!
Here is complete code:
Settings:
ITEM_PIPELINES = {
'mutualartproject.pipelines.MyImagesPipeline': 1,
}
IMAGES_STORE = 'images'
Pipline:
class MyImagesPipeline(ImagesPipeline):
def get_media_requests(self, item, info):
for image_url in item['image_urls']:
yield scrapy.Request(image_url)
def item_completed(self, results, item, info):
image_paths = [x['path'] for ok, x in results if ok]
if not image_paths:
raise DropItem("Item contains no images")
return item
Just adding my misstake here which threw me of for several hours. Perhaps it can help someone.
From scrapy docs (https://doc.scrapy.org/en/latest/topics/media-pipeline.html#using-the-images-pipeline):
Then, configure the target storage setting to a valid value that will be used for storing the downloaded images. Otherwise the pipeline will remain disabled, even if you include it in the ITEM_PIPELINES setting.
For some reason I used a colon ":" instead of an equal sign "=".
# My misstake:
IMAGES_STORE : '/Users/my_user/images'
# Working code
IMAGES_STORE = '/Users/my_user/images'
This dosen't return an error but instead leads to the pipeline not loading at all which for me was pretty hard to trouble shoot.
You have to enable SPIDER_MIDDLEWARES and DOWNLOADER_MIDDLEWARES in the settings.py file
