How to download files from website using PHP with Python

To get the filename from the URL after redirects, check the Content Disposition header in the response. Here's a code that extracts the filename and extension from the response headers.

import requests from urllib.parse import unquote
    
def get_filename_from_cd(cd):
    """
    Get filename from content disposition header
    """
    if not cd:
        return None
    fname = None
    for param in cd.split(';'):
        if 'filename' in param.lower():
            fname = param.split('=')[1].strip()
            break
    return unquote(fname)
    
url = 'https://www.portablefreeware.com/download.php?dd=1159'
r = requests.get(url,allow_redirects=True)
    
# Get the file name from the headers
filename = get_filename_from_cd(r.headers.get('content-disposition'))
    
if filename:
    with open(filename, 'wb') as file:
    file.write(r.content)
else:
    print("Couldn't find the file name in the response headers.")

If that doesn't work.

import requests
import mimetypes

response = requests.get('https://www.portablefreeware.com/download.php?dd=1159')
content=response.content
content_type = response.headers['Content-Type']
ext= mimetypes.guess_extension(content_type)


print(content)# [ZipBinary]
print(ext)# .zip
print(content_type)#application/zip, application/octet-stream

with open("newFile."+ext, 'wb') as f:
  f.write(content)
  f.close()

With your use of the allow_redirects=True option, requests.get would automatically follow the URL in the Location header of the response to make another request, losing the headers of the first response as a result, which is why you can't find the file name information anywhere.

You should instead use the allow_redirects=False option so that you can the Location header, which contains the actual download URL:

import requests

url = 'https://www.portablefreeware.com/download.php?dd=1159'
r = requests.get(url, allow_redirects=False)
print(r.headers['Location'])

This outputs:

https://www.diskinternals.com/download/Linux_Reader.exe

You can then make another request to the download URL, and use os.path.basename to obtain the name of the file to which the content will be written:

import os

url = r.headers['Location']
with open(os.path.basename(url), 'w') as file:
    r = requests.get(url)
    file.write(r.content)

You're using requests for downloading. This doesn't work with downloads of this kind.

Try urllib instead:

import urllib.request

urllib.request.urlretrieve(url, filepath)

You can download the file with file name get from response header.

Here's my code for a download with a progress bar and a chunk size buffer:

1. To display a progress bar, use tqdm. pip install tqdm
2. In this, chunk write is used to save memory during downloading.

import os

import requests
import tqdm
url = "https://www.portablefreeware.com/download.php?dd=1159"
response_header = requests.head(url)
file_path = response_header.headers["Location"]
file_name = os.path.basename(file_path)
with open(file_name, "wb") as file:
    response = requests.get(url, stream=True)
    total_length = int(response.headers.get("content-length"))
    for chunk in tqdm.tqdm(response.iter_content(chunk_size=1024), total=total_length / 1024, unit="KB"):
        if chunk:
            file.write(chunk)
            file.flush()

Progress output:

6%|▌         | 2848/46100.1640625 [00:04<01:11, 606.90KB/s]

redirectable can be bounced via DNS distributed Network any where. So the example answers above show https://www but in my case they will be resolved to Europe so my fastest local source is coming in as

https://eu.diskinternals.com/download/Linux_Reader.exe

by far the simplest is to raw curl first if its good no need to inspect or scrape

without bothering to resolve anything,
curl -o 1159.tmp https://www.portablefreeware.com/download.php?dd=1159

however I know in this case that not the expected result, so next level is

curl -I https://www.portablefreeware.com/download.php?dd=1159 |find "Location"

and that gives the result as shown by others
https://www.diskinternals.com/download/Linux_Reader.exe but that's not the fuller picture since if we back feed that

curl.exe -K location.txt

we get

<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html><head>
<title>301 Moved Permanently</title>
</head><body>
<h1>Moved Permanently</h1>
<p>The document has moved <a href="https://eu.diskinternals.com/download/Linux_Reader.exe">here</a>.</p>
</body></html>

hence the nested redirects to

https://eu.diskinternals.com/download/Linux_Reader.exe

all of that can be command line scripted to run in loops in a line or two but I don't use Python so you will need to write perhaps a dozen lines to do similar
