I am trying to scrape https://www.olx.com.eg/en/properties/ listings and there it is showing 200,000+ ads and I'd like to scrape all 200,000 listings but pagination don't go above 49 pages. I have figure out their api endpoint from where data is coming through.
Api endpoint:
'https://search.olx.com.eg/_msearch?filter_path=took%2C*.took%2C*.suggest.*.options.text%2C*.suggest.*.options._source.*%2C*.hits.total.*%2C*.hits.hits._source.*%2C*.hits.hits.highlight.*%2C*.error%2C*.aggregations.*.buckets.key%2C*.aggregations.*.buckets.doc_count%2C*.aggregations.*.buckets.complex_value.hits.hits._source%2C*.aggregations.*.filtered_agg.facet.buckets.key%2C*.aggregations.*.filtered_agg.facet.buckets.doc_count%2C*.aggregations.*.filtered_agg.facet.buckets.complex_value.hits.hits._source'
POST data:
data = '{"index":"olx-eg-production-ads-ar"}\n{"from":0,"size":0,"track_total_hits":false,"query":{"bool":{"must":[{"term":{"category.slug":"properties"}}]}},"aggs":{"category.lvl1.externalID":{"global":{},"aggs":{"filtered_agg":{"filter":{"bool":{"must":[{"term":{"category.lvl0.externalID":"138"}}]}},"aggs":{"facet":{"terms":{"field":"category.lvl1.externalID","size":20}}}}}},"location.lvl1":{"global":{},"aggs":{"filtered_agg":{"filter":{"bool":{"must":[{"term":{"category.slug":"properties"}},{"term":{"location.lvl0.externalID":"0-1"}}]}},"aggs":{"facet":{"terms":{"field":"location.lvl1.externalID","size":20},"aggs":{"complex_value":{"top_hits":{"size":1,"_source":{"include":["location.lvl1"]}}}}}}}}},"product":{"global":{},"aggs":{"filtered_agg":{"filter":{"bool":{"must":[{"term":{"category.slug":"properties"}},{"term":{"product":"featured"}},{"term":{"location.externalID":"0-1"}}]}},"aggs":{"facet":{"terms":{"field":"product","size":20},"aggs":{"complex_value":{"top_hits":{"size":1,"_source":{"include":["product"]}}}}}}}}},"totalProductCount":{"global":{},"aggs":{"filtered_agg":{"filter":{"bool":{"must":[{"term":{"category.slug":"properties"}},{"term":{"product":"featured"}}]}},"aggs":{"facet":{"terms":{"field":"product","size":20},"aggs":{"complex_value":{"top_hits":{"size":1,"_source":{"include":["totalProductCount"]}}}}}}}}}}}\n{"index":"olx-eg-production-ads-ar"}\n{"from":0,"size":45,"track_total_hits":200000,"query":{"function_score":{"random_score":{"seed":97},"query":{"bool":{"must":[{"term":{"category.slug":"properties"}},{"term":{"product":"featured"}}]}}}},"sort":["_score"]}\n{"index":"olx-eg-production-ads-ar"}\n{"from":10045,"size":45,"track_total_hits":200000,"query":{"bool":{"must":[{"term":{"category.slug":"properties"}}]}},"sort":[{"timestamp":{"order":"desc"}},{"id":{"order":"desc"}}]}\n'
Problem is even this elasticsearch endpoint have a limitation of 10000 listings when I try to increase the from value in POST data it throws:
{"message":"[query_phase_execution_exception] Result window is too large, from + size must be less than or equal to: [10000] but was [10045]. See the scroll api for a more efficient way to request large data sets. This limit can be set by changing the [index.max_result_window] index level setting.","error":{"status":500}
I'd like to get all the 200,000 listings, any work around?

How to overcome this 10000 limit? Thanks in Advance.

Im new to Python and Im trying to code a commentscraper for youtube with the most important informations, which I put in a JSON-file. But the my amount of comments and replys is not the same as on Youtube. I don't know, where my error is. I recognized, that it doesn't write any data in the files, if there are less than 20 comments, but I don't know, where I have to change something...
Example:
https://youtu.be/Re1m9O7q-9U here I get 102, but it should be 107
https://youtu.be/Q9Y5m1fQ7Fk here I get 423, but it should be 486
https://youtu.be/cMhE5BfmFkM here I get 1315, but it should be 2052
Here is the code:

I want to use 'i' variable to loop in the xpath of tr[position] from 4 to 2235. i just dont know if it is possible! and if it is possible, then what is the right way to do it? mine does not work.
Sure, it is possible and widely used.
You can format the string with variable.
There are several syntaxes for that.
For example you can do it like this:
i = 4
while i<2236:
assetid_path = "//table[2]//tr[{1}]/td[2]/text()".format(i)
assetcategory_path = "//table[2]//tr[{1}]/td[3]/text()".format(i)
schemecode_path = "//table[2]//tr[{1}]/td[5]/text()".format(i)
link_path = "//table[2]//tr[{1}]/td[6]/a/#href".format(i)
schemename_path = "//table[2]//tr[{1}]/td[7]/text()".format(i)
assetid = response.xpath(assetid_path)
assetcategory = response.xpath(assetcategory_path)
schemecode = response.xpath(schemecode_path)
link = response.xpath(link_path)
schemename = response.xpath(schemename_path)
yield {
'assetid' : assetid,
'assetcategory' : assetcategory,
'schemecode' : schemecode,
'link' : link,
'schemename' : schemename
}
i += 1
While the above can be shortened like this:
i = 4
while i<2236:
root_path = "//table[2]//tr[{1}]".format(i)
assetid_path = root_path + "/td[2]/text()"
assetcategory_path = root_path + "/td[3]/text()"
schemecode_path = root_path + "/td[5]/text()"
link_path = root_path + "/td[6]/a/#href"
schemename_path = root_path + "/td[7]/text()"
assetid = response.xpath(assetid_path)
assetcategory = response.xpath(assetcategory_path)
schemecode = response.xpath(schemecode_path)
link = response.xpath(link_path)
schemename = response.xpath(schemename_path)
yield {
'assetid' : assetid,
'assetcategory' : assetcategory,
'schemecode' : schemecode,
'link' : link,
'schemename' : schemename
}
i += 1
But the better way is to use bind variable. As following:
i = 4
while i<2236:
assetid = response.xpath("//table[2]//tr[$i]/td[2]/text()",i=i))
assetcategory = response.xpath("//table[2]//tr[$i]/td[3]/text()",i=i))
schemecode = response.xpath("//table[2]//tr[$i]/td[5]/text()",i=i)
link = response.xpath("//table[2]//tr[$i]/td[6]/a/#href",i=i)
schemename = response.xpath("//table[2]//tr[$i]/td[7]/text()",i=i)
yield {
'assetid' : assetid,
'assetcategory' : assetcategory,
'schemecode' : schemecode,
'link' : link,
'schemename' : schemename
}
i += 1
You send string to xpath so I would suggest to use formating... eg.:
response.xpath(f"//table[2]//tr[{i}]/td[2]/text()")
I have the following view function used to scrape data:
def results(request):
if request.method == 'POST':
form = RoomForm(request.POST)
if form.is_valid():
form_city = form.cleaned_data['city'].title()
form_country = form.cleaned_data['country'].title()
form_arrival_date = form.cleaned_data['arrival_date']
form_departure_date = form.cleaned_data['departure_date']
form_pages_to_scrape = form.cleaned_data['pages_to_scrape']
#launch scraper
scraper = AIRBNB_scraper(city=form_city, country=form_country, arrival_date=str(form_arrival_date), departure_date=str(form_departure_date))
scraped_dataframe = scraper.scrape_multiple_pages(last_page_selector_number=form_pages_to_scrape)
scraped_dataframe_sorted = scraped_dataframe.sort_values('prices')
print(scraped_dataframe_sorted)
#convert scraped dataframe into lists
prices = scraped_dataframe_sorted['prices'].tolist()
listings_links = scraped_dataframe_sorted['listings_links'].tolist()
listings_names = scraped_dataframe_sorted['listings_names'].tolist()
photo_links = scraped_dataframe_sorted['photo_links'].tolist()
dictionary = zip(prices, listings_links, listings_names, photo_links)
context = {'dictionary': dictionary}
return render(request, 'javascript/results.html', context)
On form submit, a post request is sent to this function using AJAX:
var frm = $('#login-form');
frm.submit(function () {
$.ajax({
type: "POST",
url: "/results",
data: frm.serialize(),
success: function (data) {
$("#table").html(data);
$('#go_back').remove();
},
error: function(data) {
$("#table").html("Something went wrong!");
}
});
return false;
});
After that the scraped data is displayed as HTML table on the same page the form is on.
The problem is the number of scraped items doubles every time the form submit is done. So for example if the number of scraped items on first button click is sixteen, the output will be 16, but on the second run it will be 32, then 64, and so on.
It is like the app remembers previous form submits, but I don't see any reason why. I tried clearin - at the end of this function - the pandas dataframe used to store the scraped data and also the dictionary passed as context, but to no avail.
The form is:
class RoomForm(forms.Form):
city = forms.CharField(max_length=100)
country = forms.CharField(max_length=100)
arrival_date = forms.DateField(widget=forms.DateInput(attrs=
{
'class':'datepicker'
}), required=False)
departure_date = forms.DateField(widget=forms.DateInput(attrs=
{
'class':'datepicker'
}), required=False)
pages_to_scrape = forms.IntegerField(label='Pages to scrape (max. 17)', min_value=0, max_value=17, widget=forms.NumberInput(attrs={'style':'width: 188px'}))

You have module-level variables: prices, listings_links, etc. You append to these inside your AIRBNB_scraper instance but they are not part of that instance, and will persist between calls. You should make them instance attributes - define them as self.prices etc in the __init__ method.

i found key adaptive_fmts and url_encoded_fmt_stream_map contain multiple url in percent-encoded form.
i take one url from url_encoded_fmt_stream_map it look like this

Please help me.

What is difference between adaptive_fmts and url_encoded_fmt_stream_map containing urls?
In python2.7, this works:
import urlparse, urllib2
vid = "vzS1Vkpsi5k"
save_title = "YouTube SpaceX - Booster Number 4 - Thaicom 8 06-06-2016"
url_init = "https://www.youtube.com/get_video_info?video_id=" + vid
resp = urllib2.urlopen(url_init, timeout=10)
data = resp.read()
info = urlparse.parse_qs(data)
title = info['title']
print "length: ", info['length_seconds'][0] + " seconds"
stream_map = info['adaptive_fmts'][0]
vid_info = stream_map.split(",")
mp4_filename = save_title + ".mp4"
for video in vid_info:
item = urlparse.parse_qs(video)
#print 'quality: ', item['quality'][0]
#print 'type: ', item['type'][0]
url_download = item['url'][0]
resp = urllib2.urlopen(url_download)
print resp.headers
length = int(resp.headers['Content-Length'])
my_file = open(mp4_filename, "w+")
done, i = 0, 0
buff = resp.read(1024)
while buff:
my_file.write(buff)
done += 1024
percent = done * 100.0 / length
buff = resp.read(1024)
if not i%1000:
percent = done * 100.0 / length
print str(percent) + "%"
i += 1
break
