been through a few web scraping tutorials now trying a basic api scraper.
This is my code
from bs4 import BeautifulSoup
import requests
url = 'https://qships.tmr.qld.gov.au/webx/services/wxdata.svc/GetDataX'
response = requests.get(url, timeout=5)
content = BeautifulSoup(response.content, "html.parser")
print (content)
comes up with method not allowed :(
Im still learning so any advice will be well recieved
cheers
It is clearly a problem with your URL, service doesn't allow to retrieve information. but you can check this URL, where the steps for retrieving metadata are described.
https://qships.tmr.qld.gov.au/webx/services/wxdata.svc

A website url www.example.com/abc does not change when iterating over different pages. After inspecting using DEV TOOLS on CHROME browser XHR tab it is noticed that POST request is posted to url www.example.com/abc-data and based on which response source code of url www.example.com/abc changes.
However 90% of the data is being returned and can be scraped from XHR response, but 10% of the data is present in dynamic source code which is updated depending on XHR response.
I've tried all the possible available solutions on internet but not able to crack the solution for this problem.
Env:
Mac OS X Ventura
Python 3.7.3
Note: Using BeautifulSoup
Short code snippet
url1 = www.example.com/abc
url2 = www.example.com/abc-data
with requests.Session() as s:
r = s.get(url1) # Extract token from this URL
# SOME CODE HERE
r = s.post(url2, data=payload) # Use token from above for this URL and session
soup = BeautifulSoup(r.text, 'html.parser')
After POST request as above, HTML SOURCE CODE is updated and I am not able to get that using BeautifulSoup.
What I am receiving is just JSON response.
Any help would be much appreciated!!!
As I understood, you're trying to get the dynamic content of a web page using BeautifulSoup. That is not possible to do. BeautifulSoup only scrapes static web content.
If you really want to get the Dynamic Content, I recommend using Selenium.
I tried to getting the title of a web page by web scraping using Beautifulsoup4 python module and it's returning a string "Not Acceptable!" as the title, but when I open the webpage via browser the title is different. I tried looping through list of links and extract titles of all the webpages but it's returning the same string "Not Acceptable!" for all the links.
here is the python code
from bs4 import BeautifulSoup
import requests
URL = 'https://insights.blackcoffer.com/how-is-login-logout-time-tracking-for-employees-in-office-done-by-ai/'
result = requests.get(URL)
doc = BeautifulSoup(result.text, 'html.parser')
tag = doc.title
print(tag.get_text())
here is link to the corresponding web page webpage link
I don't know if it is a problem with Beautifulsoup4 or with requests library, is it because the site has enabled bot protection and not returning the HTML when sending the requests?
The server expects the User-Agent header. Interestingly, it is happy with any User-Agent, even a fictitious one:
result = requests.get(URL, headers = {'User-Agent': 'My User Agent 1.0'})
An easy way to debug this kind of issue is to print (or write to a file) the request.text. This is because some servers don't allow scraping. Some websites generate HTML using JavaScript at runtime (e.g. YouTube). These are some of the scenarios where the request.text can be different than the source HTML we see in the browser. The below text has been returned by the server.
<head><title>Not Acceptable!</title></head><body><h1>Not Acceptable!</h1><p>An appropriate representation of the requested resource could not be found on this server. This error was generated by Mod_Security.</p></body></html>
Edit:
As pointed by DYZ, this is a 406 error and User Agent in the request header was missing.
https://www.exai.com/blog/406-not-acceptable
The 406 Not Acceptable status code is a client-side error. It's part
of the HTTP response status codes in the 4xx category, which are
considered client error responses
I have been struggling to do a web scraping with the below code and its showing me null records. If we print the output data, it dosent show the requested output. this is the web site i am going to do this web scraping https://coinmarketcap.com/. there are several pages which need to be taken in to the data frame. (64 Pages)
import requests
import pandas as pd
url = "https://api.coinmarketcap.com/data-api/v3/topsearch/rank"
req= requests.post(url)
main_data=req.json()
can anyone help me to sort this out?
Instead of using post requests use get in request call it will
work!
import requests
res=requests.get("https://api.coinmarketcap.com/data-api/v3/topsearch/rank")
main_data=res.json()
data=main_data['data']['cryptoTopSearchRanks']
With All pages: You can find this URL from Network tab go to xhr and reload now go to second page URL will avail in xhr tab you can copy and make call of it i have shorten the URL here
res=requests.get("https://coinmarketcap.com/")
soup=BeautifulSoup(res.text,"html.parser")
last_page=soup.find_all("p",class_="sc-1eb5slv-0 hykWbK")[-1].get_text().split(" ")[-1]
res=requests.get(f"https://api.coinmarketcap.com/data-api/v3/cryptocurrency/listing?start=1&limit={last_page}&sortBy=market_cap&sortType=desc&convert=USD,BTC,ETH&cryptoType=all&tagType=all&audited=false&aux=ath")
Now use json method
data=res.json()['data']['cryptoCurrencyList']
print(len(data))
Output:
6304
For getting/reading the data you need to use get method not post
import requests
import pandas as pd
import json
url = "https://api.coinmarketcap.com/data-api/v3/topsearch/rank"
req = requests.get(url)
main_data = req.json()
print(main_data) # without pretty printing
pretty_json = json.loads(req.text)
print(json.dumps(pretty_json, indent=4)) # with pretty print
Their terms of use prohibit web scraping. The site provides a well-documented API that has a free tier. Register and get API token:
from requests import Session
url = 'https://pro-api.coinmarketcap.com/v1/cryptocurrency/listings/latest'
parameters = {
'start':'1',
'limit':'5000',
'convert':'USD'
}
headers = {
'Accepts': 'application/json',
'X-CMC_PRO_API_KEY': HIDDEN_TOKEN, # replace that with your API Key
}
session = Session()
session.headers.update(headers)
response = session.get(url, params=parameters)
data = response.json()
print(data)
I'm trying to scrape multiple financial websites (Wells Fargo, etc.) to pull my transaction history for data analysis purposes. I can do the scraping part once I get to the page I need; the problem I'm having is getting there. I don't know how to pass my username and password and then navigate from there. I would like to do this without actually opening a browser.
I found Michael Foord's article "HOWTO Fetch Internet Resources Using The urllib Package" and tried to adapt one of the examples to meet my needs but can't get it to work (I've tried adapting to several other search results as well). Here's my code:
import bs4
import urllib.request
import urllib.parse
##Navigate to the website.
url = 'https://www.wellsfargo.com/'
values = {'j_username':'USERNAME', 'j_password':'PASSWORD'}
data = urllib.parse.urlencode(values)
data = data.encode('ascii')
req = urllib.request.Request(url, data)
with urllib.request.urlopen(req) as response:
the_page = response.read()
soup = bs4.BeautifulSoup(the_page,"html.parser")
The 'j_username' and 'j_password' both come from inspecting the text boxes on the login page.
I just don't think I'm pointing to the right place or passing my credentials correctly. The URL I'm using is just the login page so is it actually logging me in? When I print the URL from response it returns https://wellsfargo.com/. If I'm ever able to successfully login, it just takes me to a summary page of my accounts. I would then need to follow another link to my checking, savings, etc.
I really appreciate any help you can offer.
I am using cookielib and some times opening a url in browser downloads many other files by browser making many other requests. Can I replicate the same behaviour using cookie lib or any other python library?
For example: To get all the required information from page https://applicant.keybank.com/psp/hrsappl/EMPLOYEE/HRMS/c/HRS_HRAM.HRS_CE.GBL?Page=HRS_CE_HM_PRE&Action=A&SiteId=1
I have to make more than 1 GET requests from my python script. I got the request urls of all the requests browser makes by analysing the network requests when I opened the page.
I am seeing if there is any way I can just make 1 request and it fetches all the related requests by itself like browser.
I am not very much interested in the js or css but the main html.
I tried with the following code but it couldn't download whole page
cj = cookielib.CookieJar()
opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cj))
response = opener.open('https://applicant.keybank.com/psp/hrsappl/EMPLOYEE/HRMS/c/HRS_HRAM.HRS_CE.GBL?Page=HRS_CE_HM_PRE&Action=A&SiteId=1')
html = response.read()
but when I fetched 3 other GET urls in sequence it is able to give me the required html in the third GET response. I got these urls by examining network tab of the browser

requests can handle cookies, as you can see here.
It's a great library, far more powerful that urllib2, and yet simpler-looking.
>>> import requests
>>> r = requests.get('https://applicant.keybank.com/psp/hrsappl/EMPLOYEE/HRMS/c/HRS_HRAM.HRS_CE.GBL?Page=HRS_CE_HM_PRE&Action=A&SiteId=1')
>>> r.cookies
Edit: This answer dos not really address the problem, I read too fast. Sorry about that.
As suggested by #J.F.Sebastian, I'm adding a link to a python webkit client, Ghost.py, that could emulate a browser, as you requested.
