How to fix HTML downloading instead of image file - python

I'm trying to download a file from a link using urllib in Python 3.7 and it downloads the HTML file and not the Image File.
So I'm trying to receive information from a Google Form, the information is sent to a Google Sheet. I'm able to receive the information in the sheet no problem. However the Form requires an Image submission which appears in the sheet as a URL. (Example: https://drive.google.com/open?id=1YCBmEOz6_l7WDQw5t6AYBSb9B5XXKTuX)
This is my code:
import urllib.request
import random
Then I create a download function:
def downloader(image_url):
file_name = random.randrange(1,10000)
full_file_name = str(file_name) + '.png'
print(full_file_name)
urllib.request.urlretrieve(image_url,full_file_name)
I get the URL and isolate the ID of the image:
ImgId="https://drive.google.com/open?id=1Mp5XYoyyEfWJryz8ojLbHuZ6V0IzERIV"
ImgId=ImgId[33:]
Then I put the ID in a download link:
ImgId="https://drive.google.com/uc?authuser=0&id="+ImgId+"&export=download"
Which results in (in the above example) "https://drive.google.com/uc?authuser=0&id=1YCBmEOz6_l7WDQw5t6AYBSb9B5XXKTuX&export=download".
Next I run the download function:
downloader(ImgId)
So after this I expected the png file to be downloaded into the folder of the program, however it downloaded a html file of the google drive log-in page instead of an image file, or even an html file of the image. Noting that to view or download the image it requires you to be signed in to Google to download in the browser, could authorization be an issue?
(Note: If I manually paste the download link as generated by the program into my browser it downloads the image correctly)
(P.S I'm an absolute noob, so yeah)
(Thanks in advance for any answers)


Instead of using urllib for dowmloading, use requests and get the page contents using GET rest call and then convert the response content to soup content using beautifulsoup and then point to the content which you want to download, as the download function inside html would have a download link associated with it and then send a get request again with js download.
import requests
import bs4
response = requests.get(<your_url>)
soup = bs4.BeautifulSoup(response.content, 'html5lib')
# Get the download link and supply all the necessary values to the link
# Initiate Requests again

Requests Module not fetching full website in Python

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.

trying to download full HTML pages

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.

Scraping a secure website requiring clicks on javascript links

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&regl=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.

"403 Forbidden" when use python urlib package to download the image

i am new to urllib package.
i try to download all the images in website "http://www.girl-atlas.com/album/576545de58e039318beb37f6"
the question is: when i copy the the url of an image, and pass the url to a browser, i will get an error "403 Forbidden". However, when i right click an image in the browser, and choose to open the image in a new window, this time, i will get the image in the new window.
the problem is: how the urlib simulates the second way?

It is forbidden to use the URLs outside a broweser. To ensure this, browsers send always a referer, the site, from which the image is loaded. If a browser would be written in Python, this would look like this:
import urllib.request
opener = urllib.request.URLopener()
opener.addheader('Referer', 'http://www.girl-atlas.com/album/576545de58e039318beb37f6')
image = opener.open('http://girlatlas.b0.upaiyun.com/41/20121222/234720feaa1fc912ba4e.jpg!lrg')
data = image.read()
image.close()

How to download a file using python that is sent after some delay by server?

I have to download a large number of files from a local server. When opening the URL in the browser[Firefox], the page opens with content "File being generated.. Wait.." and then the popup comes up with the option to save the required .xlsx file.
I tried to save the page object using urllib, but it saves the .html file with the content as "File being generated.. Wait..". I used the code as described here (using urllib2):
How do I download a file over HTTP using Python?
I don't know how to download the file that is sent later by the server. It works fine in browser. How to emulate it using python?

first of all you have to know the exact URL where the document is generated. You can use firefox and the addons Http Live Headers.
And then use python to "simulate" the same request.
I hope that help.
PD: or share the url of the site and then I could help to you better.

import requests
url = 'https://readthedocs.org/projects/python-guide/downloads/pdf/latest/'
myfile = requests.get(url, allow_redirects=True)
open('c:/example.pdf', 'wb').write(myfile.content)
A bit old but faced the same problem.
The key to solution is in allow_redirects=True.

Is it as simple as
import urllib2
import time
response = urllib2.urlopen('http://www.example.com/')
time.sleep(10) # Or however long you need.
html = response.read()
