As we know, the general request headers are always like "User-Agent:Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/64.0.3282.140 Safari/537.36", or "Accept:application/json, text/plain".
But this time, I find a request header: "41d9251ae3b6e89193fe:1b237fc9847ec56e144031e03cc72d704777ef4167026f236eb3dd8d2c5b15ad837a20c8ce14459ae9f5c36e581b1322229b548178cce6cdf07ebbea7765f2df", and I have never seen a request header like that.
What does it mean?

i am trying to scrape a website "https://coinatmradar.com/" . I am using requests, beautifulsoup and selenium (wherever required) to scrape data. But after a while, my ip got blocked by the website as it was using cloudflare protection.
country_url = "https://coinatmradar.com/country/226/bitcoin-atm-united-states/"
headers = {'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.102 Safari/537.36'}
response=requests.get(country_url, headers=headers)
soup=BeautifulSoup(response.content,'lxml')
This is the part of code that i am using. I am getting response 403. Is there other way around to make it work with requests and selenium both?
Try to set your headers like that:
headers = {'Cookie':'_gcar_id=0696b46733edeac962b24561ce67970199ee8668', 'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.102 Safari/537.36'}
I want to send http request using protobuf as params on python. I copied the protobuf data from charles proxy (web debugging proxy tool).
the protobuf text request data was:1 { 1: "2345654456765" }
i tried this but not working:
import requests
r = requests.post('https://api.website.com/version/auth/login?locale=en',data={1:{1:'2345654456765'}},headers={'user-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/85.0.4181.9 Safari/537.36','platform': 'web',})
print(r.content)
I have no idea of how can I put this as a param. I always worked with json data. Is there anyone who knows the solution?
We have a website (with CloudFlare in front).
We are constantly getting scanned/checked for vulnerabilities and requests look like this:
2020-01-28 14:19:59 Content type: application/x-www-form-urlencoded
2020-01-28 14:19:59 Request content: <?=md5("phpunit")?>

2020-01-28 14:19:59 REMOTE_ADDR: 5.101.0.209
2020-01-28 14:19:59 REMOTE_HOST:
I have added address 5.101.0.209 to firewall in CloudFalre but requests are still coming through (somehow).
I have following questions
How can requests come via CloudFlare but variable
HTTP_CF_CONNECTING_IP is empty?
How would you recommend to defend against such scanning?
Why CloudFlare firewall does not block such request, what could be the reasons?
Thanks.
I am using requests and beautifulsoup to go through the popular comic store comixology in order to make a list of all comic titles and issues and release date for all of them, so I am requesting a massive amount of web pages. Unfortunately, partway through i will get the error:
you do not have access to (URL) on this server
I tried using a function that recursively tries the request. but this isn't working
Im not putting the whole code in because it is very long.
def getUrl(url):
try:
page = requests.get(url)
except:
getUrl(url)
return page
The User-Agent request header contains a characteristic string that allows the network protocol peers to identify the application type, operating system, software vendor or software version of the requesting software user agent. Validating User-Agent header on server side is a common operation so be sure to use valid browser’s User-Agent string to avoid getting blocked.
(Source: http://go-colly.org/articles/scraping_related_http_headers/)
The only thing you need to do is to set a legitimate user-agent. Therefore add headers to emulate a browser. :
# This is a standard user-agent of Chrome browser running on Windows 10
headers = { 'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/71.0.3578.98 Safari/537.36' }
Example:
from bs4 import BeautifulSoup
import requests
headers={'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/71.0.3578.98 Safari/537.36'}
resp = requests.get('http://example.com', headers=headers).text
soup = BeautifulSoup(resp, 'html.parser')
Additionally, you can add another set of headers to pretend like a legitimate browser. Add some more headers like this:
headers = {
'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/71.0.3578.98 Safari/537.36',
'Accept' : 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
'Accept-Language' : 'en-US,en;q=0.5',
'Accept-Encoding' : 'gzip',
'DNT' : '1', # Do Not Track Request Header
'Connection' : 'close'
}
Is there a way to log which browser/OS/etc. the user is using from my Node.js app?
Thanks
I believe you want the information stored in the Request Header "User-Agent"
var useragent = request.headers['User-Agent']
My user-agent is: "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/535.1 (KHTML, like Gecko) Chrome/13.0.782.220 Safari/535.1" for chrome
