Get a file from an ASPX webpage using Python
Question: I'm trying to download a CSV file from this site, but I keep getting an HTML
file when I'm using this piece of code (which used to work until a few weeks
ago), or when I'm using wget.

    
    
    url = "http://.....aspx"
    
    file_name = "%s.csv" % url.split('/')[3]
    u = urllib2.urlopen(url)
    f = open(file_name, 'wb')
    meta = u.info()
    file_size = int(meta.getheaders("Content-Length")[0])
    print "Downloading: %s Bytes: %s" % (file_name, file_size)
    
    file_size_dl = 0
    block_sz = 8192
    while True:
        buffer = u.read(block_sz)
        if not buffer:
            break
    
        file_size_dl += len(buffer)
        f.write(buffer)
        status = r"%10d  [%3.2f%%]" % (file_size_dl, file_size_dl * 100. / file_size)
        status = status + chr(8)*(len(status)+1)
        print status,
    

How can I get this file again with Python?

Thank you


Answer: Solved by using the Requests library instead of urllib2:

    
    
    import requests
    
    url = "http://www.....aspx?download=1"
    
    file_name = "Data.csv"
    u = requests.get(url)
    
    file_size = int(u.headers['content-length'])
    print "Downloading: %s Bytes: %s" % (file_name, file_size)
    
    with open(file_name, 'wb') as f:
        for chunk in u.iter_content(chunk_size=1024): 
            if chunk: # filter out keep-alive new chunks
                f.write(chunk)
                f.flush()
    f.close()
