I am using python requests library for making http requests. For this website : https://www.epi.org/resources/budget/ i am unable to read the HTML response as it is not human readable , looks like its protected by cloudfare ddos protection . Here is my simple code below.
import requests
headers = {'accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8',
'accept-encoding': 'gzip, deflate, br',
'accept-language': 'en-US,en;q=0.9,pt;q=0.8',
'cache-control': 'max-age=0',
'user-agent': 'Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.110 Safari/537.36',
'upgrade-insecure-requests': '1'}
s = requests.Session()
a = s.get('https://www.epi.org/resources/budget/',headers=headers)
print (a.text)
The response HTML looks like this : https://justpaste.it/6ie73
The reason why got unreadable content is Accept-Encoding. Differ from browser, if Python got gzip response we have to unpack it by ourselves. Also br need to do so but with different module brotl . So you should set 'Accept-Encoding': 'default'. Btw, if you need full content that rendering is necessary.

i did this spider, and when i make a request with that, send me to diferent web
a regret that I put the same parameters and almost the same header
def start_requests(self):
url ="https://assr.parcelquest.com/Statewide"
rows =self.getPin('parcels/Parcel.csv')
for row in rows:
params = {

'apn': 022-631-01,

yield scrapy.Request(url=self.url,headers=header,body=json.dumps(params),method='POST',callback=self.property,meta = {'parcel':row},dont_filter=True)
this is postman:
could explain me anybody why?
I am trying to extract an information with beautifulsoap, however when I do it it extracts it with very rare symbols. But when I enter directly to the page everything looks good and the page has the label <meta charset="utf-8">
my code is:
HEADERS = {
'user-agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/56.0.2924.87 Safari/537.36',
'referrer': 'https://google.com',
'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8',
'Accept-Encoding': 'gzip, deflate, br',
'Accept-Language': 'en-US,en;q=0.9',
'Pragma': 'no-cache',
}
urls = 'https://www.jcchouinard.com/web-scraping-with-python-and-requests-html/'
r = requests.get(urls, headers=HEADERS)
soup = bs4.BeautifulSoup(r.text, "html.parser")
print (soup)
Nevertheless, the result I get is this:
J{$%X Àà’8}±ŸÅ
I guess it's something with the encoding, however I don't understand why since the page is utf-8.
It is worth clarifying that this only happens in some cases, since with others I manage to extract the information without problems.
Edit: updated with a sample url.
Edit2: added the headers dictionary, which is the one that generates the problem.
The problem is Accept-Encoding HTTP header. There you have br specified, which means brotli compression method. requests module cannot handle that. Remove br and the server responds without this compression method.

...and so on.

You've just to add headers
This is the website "https://www.interlinecenter.com/" this website is making request to "http://cs.cruisebase.com/cs/forms/hotdeals.aspx?skin=605&nc=y" for loading html content in an "I-FRAME". I am making the exact same request using the same headers being sent by the browser but i am not getting the same content.
Here is the code i am using:

response = requests.get(url, timeout=10, headers=header)
byte_data = response.content

print(response)
print(byte_data)
This is the response i am getting:

I need to extract/scrape data at "https://cs.cruisebase.com/cs/forms/hotdeals.aspx?skin=605&nc=y".
Note: i don't want to use the selenium webdriver to get the data any help will be much appreciated, Thanks!
Did you try getting the headers by loading the target URL directly?
I sent a GET request to https://cs.cruisebase.com/cs/forms/hotdeals.aspx?skin=605&nc=y with the following headers, and I was able to get the complete response.
headers = {
'Accept':'text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3',
'Accept-Encoding':'gzip, deflate',
'Accept-Language':'en-GB,en;q=0.9,en-US;q=0.8,hi;q=0.7,la;q=0.6',
'Cache-Control':'no-cache',
'Connection':'keep-alive',
'Cookie':'ENTER COOKIES',
'DNT':'1',
'Host':'cs.cruisebase.com',
'Pragma':'no-cache',
'Upgrade-Insecure-Requests':'1',

}
I have left the Cookie field blank, you will have to enter cookies otherwise the page won't load. You can get the cookies from Chrome.
driver = webdriver.Chrome(r'XXXX\chromedriver.exe')
FB_bloomberg_URL = 'https://www.bloomberg.com/quote/FB:US'
driver.get(FB_bloomberg_URL)
board_members = driver.find_elements_by_xpath('//* [#id="root"]/div/div/section[3]/div[10]/div[1]/div[2]/div/div[2]')[0]
board=board_members.text
board.split('\n')
I wrote the coding above to scrape the board information from Bloomberg for FaceBook. But I have trouble to extract all board members because others are hidden behind the "View More". How can I extract all names?
Thanks for the help.
You can do whole thing with requests and grab the appropriate cookie to pass to API from prior GET. The API can be found in the network tab when clicking the view more link and inspecting the web traffic.

I am writing a simple script to get public profile visible without login on LinkedIn.
Below is my code to get the page for beautifulsoup. I am using public proxies as well.
import urllib.request, urllib.error
from bs4 import BeautifulSoup
url = "https://www.linkedin.com/company/amazon"
proxy = urllib.request.ProxyHandler({'https': proxy, })
opener = urllib.request.build_opener(proxy)
urllib.request.install_opener(opener)

'Accept-Charset': 'ISO-8859-1,utf-8;q=0.7,*;q=0.3',
'Accept-Encoding': 'gzip, deflate, br',
'Accept-Language': 'en-US,en;q=0.9,hi;q=0.8',
'Connection': 'keep-alive'}
req = urllib.request.Request(url, headers=hdr)
page = urllib.request.urlopen(req, timeout=20)
self.soup = BeautifulSoup(page.read(), "lxml")
But it is raising "HTTPError 999 - request Denied" error. This is only for testing purpose till I am getting access via partnership program.
What am I doing wrong? Please help.
You did not do anything wrong, LinkedIn blacklist cloud servers ip addresses to prevent "stealing" their data. Questionable practice but this is how it is.
