Cannot get Python request GET to work with spitogatos.gr - web-scraping

Question

I've been trying to scrape the data from www.spitogatos.gr but with no luck.
My code looks something like:
import requests
headers={
'Host': 'www.spitogatos.gr',
'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:79.0) Gecko/20100101 Firefox/79.0',
'Accept': 'application/json; charset=utf-8',
'Accept-Language': 'en-US,en;q=0.5',
'Accept-Encoding': 'gzip, deflate, br',
'Referer': 'https://www.spitogatos.gr/',
'Content-Type': 'text/plain; charset=utf-8',
'Origin': 'https://www.spitogatos.gr'
}
url = "https://www.spitogatos.gr/search/results/residential/sale/r100/m2007m/propertyType_apartment/onlyImage"
req = requests.get(url, headers=headers)
print (req)
print (req.content)
Although I get a response status 200, instead of any useful content I get the HTML message:
Pardon Our Interruption As you were browsing something about your
browser made us think you were a bot. There are a few reasons this
might happen:
You've disabled JavaScript in your web browser. You're a power user
moving through this website with super-human speed. You've disabled
cookies in your web browser. A third-party browser plugin, such as
Ghostery or NoScript, is preventing JavaScript from running. ...
Now I had a look at Firefox to see what kind of request it sends, and although it sends a POST request I did copy the Cookie that Firefox sends with it's request. So my header would look something like:
headers={
'Host': 'www.spitogatos.gr',
'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:79.0) Gecko/20100101 Firefox/79.0',
'Accept': 'application/json; charset=utf-8',
'Accept-Language': 'en-US,en;q=0.5',
'Accept-Encoding': 'gzip, deflate, br',
'Referer': 'https://www.spitogatos.gr/',
'Content-Type': 'text/plain; charset=utf-8',
'Origin': 'https://www.spitogatos.gr',
'Cookie':'PHPSESSID=iielr7e8boibudjmln9ubd3i62; spitogatosS=areaIDs%255B0%255D%3D2007%26propertyCategory%3Dresidential%26listingType%3Dsale; currentCurrency=EUR; spitogatosInfoBar_shortCuts=false; openedTabs=; _ga=GA1.2.1557987790.1597249012; _gid=GA1.2.507964674.1597249012; _gat_UA-3455846-10=1; _gat_UA-3455846-2=1; _hjid=dfd027d6-e6f1-474c-a427-c26d5f2ca64c; _cmpQcif3pcsupported=1; reese84=3:T2t/w3VdpNG5w9Knf78l7w==:Gg20L4RyGJffieidEn4Eb1Hmb3wyAtPQfmH/5WYHWfKjzLmjhkGCoTR0j5UUmKxIbkzZltWBeJ6KaPVCFa5qiaddz2Cn6OltrBdp…2YIriDYTOwLMNNxEFPDPkL/Lw2cGC0MwJ3uUg6kSP/VgPp/AYkIcVjXLgqjSwmAdGl4oQDyrAKDpn9PcN/fWSUjPrtAOAJzkWcZ7FPCfvcsnAo9oSNpXtAaZ0JLzgMKXqQqP8Jrakjo4eL9TSdFKIVEJZos=:eBpByDUvhUkR0pGwgnYacTV3VeYzKEi+4pJpI3mhQ6c=; _fbp=fb.1.1597249012911.16321581; _hjIncludedInPageviewSample=1; eupubconsent=BO4CN1PO4CN1PAKAkAENAAAAgAAAAA; euconsent=BO4CN1PO4CN1PAKAkBENDV-AAAAx5rv6_77e_9f-_fv_9ujzGr_v_e__2mccL5tn3huzv6_7fi_-0nV4u_1tfJdydkh-5YpCjto5w7iakiPHmqNeZ1nfmz1eZpRP58E09j53zpEQ_r8_t-b7BCHN_Y2v-8K96lPKACA; spitogatosHomepageMap=0'.encode('utf8')
}
Now when I do this the request will SOMETIMES work and sometimes it will give me the above message. So I keep refreshing Firefox and copy the Cookies over to my python script.
It is a hit and miss.
I have also been trying to replicate the exact POST request of firefox (identical data, params and headers) but this gives me the same error message.
Firefox does not seem to have this problem, no matter how many requests or refreshes I do.
Can someone help me please?
Thanks

Answer 1

Specifying User-Agent and Accept-Language I was able to get correct response every time (try to change User-Agent header to Linux one, as I have in example):
import requests
headers = {
'User-Agent': 'Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:79.0) Gecko/20100101 Firefox/79.0',
'Accept-Language': 'en-US,en;q=0.5'
}
url = 'https://www.spitogatos.gr/search/results/residential/sale/r100/m2007m/propertyType_apartment/onlyImage'
print( requests.get(url, headers=headers).text )

I have resolved the problem : the answer was so simple in fact. It's the "adblocker ultimate" that were the cause of the blockage.
So if you have some adds blockers, you could try to desactivate them, just to see, because the website could identify you as a bot when you use them.
But just to know, i have 3 adds blockers (addblock plus, ublock origin and adblocker ultimate) and it seems that only adblocker ultimate (installed very recently, while i have the others since months) caused the trouble.
I hope this solution could work for you too, if you're in the same case; or could help anybody else.
