Sorry for a Noob question.... I have written a code which searches google for an image stored locally on my computer. I accomplished this using the requests module. I want to scrape the result page for information about the image but request module never fetches the entire page. It only fetches a part of it and thus I am not able to scrape the website for results
import requests
import webbrowser
from bs4 import BeautifulSoup
filePath = "C:\\Users\\mjjha\\Documents\\Checkrow\\monaLisa.jpg"
searchUrl = 'http://www.google.com/searchbyimage/upload'
multipart = {'encoded_image': (filePath, open(filePath, 'rb')), 'image_content': ''}
response = requests.post(searchUrl, files=multipart, allow_redirects=False)
fetchUrl = response.headers['Location']
r=requests.get(fetchUrl)
webbrowser.open(fetchUrl)
soup=BeautifulSoup(r.content,'html.parser')
head=soup.find_all('a')
for i in head:
print(i['href'])
The web page looks like this:
but when I scrape it for anchor tag links using beautiful soup I get the following result:

The content fetched by requests module doesn't contain the full web page I don't know why. I want to scrape information in image ,anchor and h3 tags from the page using beautiful soup but its just not working out.
The main problem is Python Requests module doesn't render JavaScript. As a result, you are not getting the webpage you are supposed to get.
You are using a webbrowser module to view your URL where JavaScript is enabled, so you are getting the page as expected. But next, when you use the requests module to get the page, javascript stays disabled, and google doesn't let you render the page but instead redirects you to another page(Google Homepage). And there, you get different HTML resulting in no search results(you did in the first place).
IN 1 is the URL you are trying to hit, and 2 is the URL you are redirected to.
Look at the difference is google.com/webhp?tbs=sbi:AMhZZisX...
VS google.com/search?tbs=sbi:AMhZZisX...
The HTML of that page results in is this -
Always use the source HTML given by the requests module, which shows you the actual result.
As you can see, this is not the search result page.
So to reach your goal, try using Selenium.

Here is the site I am trying to scrap data from:
https://www.onestopwineshop.com/collection/type/red-wines
import requests
from bs4 import BeautifulSoup
url = "https://www.onestopwineshop.com/collection/type/red-wines"
response = requests.get(url)
#print(response.text)
soup = BeautifulSoup(response.content,'lxml')
The code I have above.
It seems like the HTML content I got from the inspector is different from what I got from BeautifulSoup.
My guess is that they are preventing me from getting their data as they detected I am not accessing the site with a browser. If so, is there any way to bypass that?
(Update) Attempt with selenium:
from selenium import webdriver
import time
path = "C:\Program Files (x86)\chromedriver.exe"
# start web browser
browser=webdriver.Chrome(path)
#navigate to the page
url = "https://www.onestopwineshop.com/collection/type/red-wines"
browser.get(url)
# sleep the required amount to let the page load
time.sleep(3)
# get source code
html = browser.page_source
# close web browser
browser.close()
Update 2:(loaded with devtool)
Any website with content that is loaded after the inital page load is unavailable with BS4 with your current method. This is because the content will be loaded with an AJAX call via javascript and the requests library is unable to parse and run JS code.
To achieve this you will have to look at something like selenium which controls a browser via python or other languages... There is a seperate version of selenium for each browser i.e firefox, chrome etc.
Personally I use chrome so the drivers can be found here...
https://chromedriver.chromium.org/downloads
download the correct driver for your version of chrome
install selenium via pip
create a scrape.py file and put the driver in the same folder.
then to get the html string to use with bs4
from selenium import webdriver
import time
# start web browser
browser=webdriver.Chrome()
#navigate to the page
browser.get('http://selenium.dev/')
# sleep the required amount to let the page load
time.sleep(2)
# get source code
html = browser.page_source
# close web browser
browser.close()
You should then be able to use the html variable with BS4
I'll actually turn my comment to an answer because it is a solution to your problem :
As other said, this page is loaded dynamically, but there are ways to retrieve data without running javascript, in your case you want to look at the "network" tab or your dev tools and filter "fetch" requests.
This could be particularly interesting for you :
You don't need selenium or beautifulsoup at all, you can just use requests and parse the json, if you are good enough ;)
There is a working cURL requests : curl 'https://api.commerce7.com/v1/product/for-web?&collectionSlug=red-wines' -H 'tenant: one-stop-wine-shop'
You get an error if you don't add the tenant header.
And that's it, no html parsing, no waiting for the page to load, no javascript running. Much more powerful that the selenium solution.
I am tring to download few hundreds of HTML pages in order to parse them and calculate some measures.
I tried it with linux WGET, and with a loop of the following code in python:
url = "https://www.camoni.co.il/411788/168022"
html = urllib.request.urlopen(url).read()
but the html file I got doen't contain all the content I see in the browser in the same page. for example text I see on the screen is not found in the HTML file. only when I right click the page in the browser and "Save As" i get the full page.
the problem - I need a big anount of pages and can not do it by hand.
URL example - https://www.camoni.co.il/411788/168022 - thelast number changes
thank you
That's because that site is not static. It uses JavaScript (in this example jQuery lib) to fetch additional data from server and paste on page.
So instead of trying to GET raw HTML you should inspect requests in developer tools. There's a POST request on https://www.camoni.co.il/ajax/tabberChangeTab with such data:
tab_name=tab_about
memberAlias=ד-ר-דינה-ראלט-PhD
currentURL=/411788/ד-ר-דינה-ראלט-PhD
And the result is HTML that pasted on page after.
So instead of trying to just download page you should inspect page and requests to get data or use headless browser such as Google Chrome to emulate 'Save As' button and save data.
I have a daily task at work to download some files from internal company website. The site requires a login. But the main url is something like:
https://abcd.com
But when I open that in the browser, it redirects to something like:
https://abcdGW/ln-eng.aspx?lang=eng&lnid=e69d5d-xxx-xxx-1111cef®l=en-US
My task normally is to open this site, login, click some links back and forth and download some files. This takes me 10 minutes everyday. But I wanna automate this using python. Using my basic knowledge I have written below code:
import urllib3
from bs4 import BeautifulSoup
import requests
import http
url = "https://abcd.com"
redirectURL = requests.get(url).url
jar = http.cookiejar.CookieJar(policy=None)
http = urllib3.PoolManager()
acc_pwd = {'datasouce': 'Data1', 'user':'xxxx', 'password':'xxxx'}
response = http.request('GET', redirectURL)
soup = BeautifulSoup(response.data)
r = requests.get(redirectURL, cookies=jar)
r = requests.post(redirectURL, cookies=jar, data=acc_pwd)
print ("RData %s" % r.text)
This shows that I am able to successfully login. The next step is something where i am stuck. On the page after login I have some links on left side, one of those I need to click. When I inspect them in Chrome, I see them as:
href="javascript:__doPostBack('myAppControl$menu_itm_proj11','')"><div class="menu-cell">
<img class="menu-image" src="images/LiteMenu/projects.png" style="border-width:0px;"><span class="menu-text">Projects</span> </div></a>
This is probably a javascript link. I need to click this, and then on new page another link, then another to download a file and back to the main page and do this all over again to download different files.
I would be grateful to anyone who can help or suggest.
Thanks to chris, I was able to complete this..
First using the request library I got the redirect url as:
redirectURL = requests.get(url).url
After that I use scrapy and selenium for click links and downloading files..
By adding selenium to the browser as add-in/plugin, it was quite simple.
I am trying to scrape data from this website. To access the tables, I need to click the "Search" button. I was able to successfully do this using mechanize:
br = mechanize.Browser()
br.open(url + 'Wildnew_Online_Status_New.aspx')
br.select_form(name='aspnetForm')
page = br.submit(id='ctl00_ContentPlaceHolder1_Button1')
"page" gives me the resulting webpage with the table, as needed. However, I'd like to iterate through the links to subsequent pages at the bottom, and this triggers javascript. I've heard mechanize does not support this, so I need a new strategy.
I believe I can get to subsequent pages using a post request from the requests library. However, I am not able to click "search" on the main page to get to the initial table. In other words, I want to replicate the above code using requests. I tried
s = requests.Session()
form_data = {'name': 'aspnetForm', 'id': 'ctl00_ContentPlaceHolder1_Button1'}
r = s.post('http://forestsclearance.nic.in/Wildnew_Online_Status_New.aspx', data=form_data)
Not sure why, but this returns the main page again (without clicking Search). Any help appreciated.
I think you should look into scrapy
you forgot some parameters in ths post request:
https://www.pastiebin.com/5bc6562304e3c
check the Post request with google dev tools
I am working on a url using python.
If I click the url, I am able to get the excel file.
but If I run following code, it gives me weird output.
>>> import urllib2
>>> urllib2.urlopen('http://intranet.stats.gov.my/trade/download.php?id=4&var=2012/2012%20MALAYSIA%27S%20EXPORTS%20BY%20ECONOMIC%20GROUPING.xls').read()
output :
"<script language=javascript>window.location='2012/2012 MALAYSIA\\'S EXPORTS BY ECONOMIC GROUPING.xls'</script>"
why its not able to read content with urllib2?
Take a look using an http listener (or even Google Chrome Developer Tools), there's a redirect using javascript when you get to the page.
You will need to access the initial url, parse the result and fetch again the actual url.
#Kai in this question seems to have found an answer to javascript redirects using the module Selenium
from selenium import webdriver
driver = webdriver.Firefox()
link = "http://yourlink.com"
driver.get(link)
#this waits for the new page to load
while(link == driver.current_url):
time.sleep(1)
redirected_url = driver.current_url
