I can not open the pdf file downloaded from the website - python

I use my requests to scrap a PDF file from a website. The file appears, but it can not be open. Here is my code:
url="https://dl.acm.org/doi/pdf/10.1145/3397271.3401063"
html=requests.get(url)
path=Mypath
with open(path, 'wb') as f:
f.write(html.content)
And when I try to open the PDF file, I get an error:
We can't open this file. Something went wrong.
I think there is something wrong with the downloaded file?

How to download a huge gz file (around 3 GB size) from a URL where there is no file name present using python

I am trying to download a file using python from a URL. However its not working and instead I am getting index.html.
Please help on same.
import requests
target_url = "https://transparency-in-coverage.uhc.com/?file=2022-07-01_United-HealthCare-Services_Third-Party-Administrator_EP1-50_C1_in-network-rates.json.gz&origin=uhc"
filename = "2022-07-01_United-HealthCare-Services_Third-Party-Administrator_EP1-50_C1_in-network-rates.json.gz"
with requests.get(target_url, stream=True) as r:
r.raise_for_status()
with open(filename, "wb") as f:
for chunk in r.iter_content(chunk_size=1024):
f.write(chunk)
That's because you're the URL you specified is for an HTML page that subsequently starts the download for the .gz file you want.
This is the link for the file:
https://mrfstorageprod.blob.core.windows.net/mrf-even/2022-07-01_ALL-SAVERS-INSURANCE-COMPANY_Insurer_PS1-50_C2_in-network-rates.json.gz?sv=2021-04-10&st=2022-07-05T22%3A19%3A13Z&se=2022-07-09T22%3A19%3A13Z&skoid=89efab61-5daa-4cf2-aa04-ce3ba9d1d1e8&sktid=db05faca-c82a-4b9d-b9c5-0f64b6755421&skt=2022-07-05T22%3A19%3A13Z&ske=2022-07-09T22%3A19%3A13Z&sks=b&skv=2021-04-10&sr=b&sp=r&sig=NaLrw2KG239S%2BpfZibvw7%2B25AAQsf9GYZ1gFK0KRN20%3D&rscd=attachment
To find it, you need to have the inspector open on the 'Network' tab whilst loading the page (or you can click on the file in the list when it loads the list of files on the page). When the download starts you'll see two files pop-up, one of which is the actual URL of the .gz file.
It does look the URL has a timestamp in it, so it might not work at a later time, I don't know.

Download file using requests python

I have a list of Url of files that open as Download Dialogue box with an option to save and open.
I'm using the python requests module to download the files. While using Python IDLE I'm able to download the file with the below code.
link = fileurl
r = requests.get(link,allow_redirects=True)
with open ("a.torrent",'wb') as code:
code.write(r.content)
But when I use this code along with for loop, the file which gets downloaded is corrupted or says unable to open.
for link in links:
name = str(links.index(link)) ++ ".torrent"
r = requests.get(link,allow_redirects=True)
with open (name,'wb') as code:
code.write(r.content)
If you are trying to download a video from a website, try
r = get(video_link, stream=True)
with open ("a.mp4",'wb') as code:
for chunk in r.iter_content(chunk_size=1024):
file.write(chunk)

Download a file without name using Python

I want to download a file, there is a hyper link in html page which does not include the file name and extension. How can I download the file using python?
For example the link is http://1.1.1.1:8080/tank-20/a/at_download/file,
but whenever I click on it the file will download and open with browser.
Use python requests to get the body of the response and write to file, this is essentially what the browser is doing when you click the link.
Try the below:
import requests
# define variables
request_url = "http://1.1.1.1:8080/tank-20/a/at_download/file"
output_file = "output.txt"
# send get request
response = requests.get(request_url)
# use 'with' to write to file
with open(output_file, 'w') as fh:
fh.write(response.content)
fh.close()

Downloaded Share Point Excel Not Opening with Open

I am re-framing an existing question for simplicity. I have the following code to download Excel files from a company Share Point site.
import requests
import pandas as pd
def download_file(url):
filename = url.split('/')[-1]
r = requests.get(url)
with open(filename, 'wb') as output_file:
output_file.write(r.content)
df = pd.read_excel(r'O:\Procurement Planning\QA\VSAF_test_macro.xlsm')
df['Name'] = 'share_point_file_path_documentName' #i'm appending the sp file path to the document name
file = df['Name'] #I only need the file path column, I don't need the rest of the dataframe
# for loop for download
for url in file:
download_file(url)
The downloads happen and I don't get any errors in Python, however when I try to open them I get an error from Excel saying Excel cannot open the file because the file format or extension is not valid. If I print the link in Jupyter Notebooks it does open correctly, the issue appears to be with the download.
Check r.status_code. This must be 200 or you have the wrong url or no permission.
Open the downloaded file in a text editor. It might be a HTML file (Office Online)
If the URL contains a web=1 query parameter, remove it or replace it by web=0.

Can't open downloaded .mp4 files downloaded with requests and urllib

I've downloaded some files using requests
url = 'https://www.youtube.com/watch?v=gp5tziO5lXg&feature=youtu.be'
video_name = url.split('/')[-1]
print("Downloading file:%s" % video_name)
# download the url contents in binary format
r = requests.get(url)
# open method to open a file on your system and write the contents
with open('saved.mp4', 'wb') as f:
f.write(r.content)
and using urllib.requests
url = 'https://www.youtube.com/watch?v=gp5tziO5lXg&feature=youtu.be'
video_name = url.split('/')[-1]
print("Downloading file:%s" % video_name)
# Copy a network object to a local file
urllib.request.urlretrieve(url, "saved2.mp4")
When I then try to open the .mp4 file I get the following error
Cannot play
This file cannot be played. This can happen because the file type is
not supported, the file extension is incorrect or the file is
corrupted.

If I test it with pytube it works fine.
What's wrong with the other methods?
To answer your question, with the other methods it is not downloading the video but the page. What you may be obtaining is an html file with an mp4 file extension.
Therefore, it gives that error when trying to open the file.
If pytube works for what you need, I would suggest using that one.
If you want to download videos from other platforms, you might consider youtube-dl.
Hello you can import IPython.display for audio diplay
import IPython.display as ipd
ipd.Audio(video_name)
regards
I hope I can have solved your problem
