Here is the link i have used (Download files from Amazon S3 with Django). Using this i'm able to download single file.
Code:
s3_template_path = queryset.values('file')
filename = 'test.pdf'
conn = boto.connect_s3('<aws access key>', '<aws secret key>')
bucket = conn.get_bucket('your_bucket')
s3_file_path = bucket.get_key(s3_template_path)
response_headers = {
'response-content-type': 'application/force-download',
'response-content-disposition':'attachment;filename="%s"'% filename
}
url = s3_file_path.generate_url(60, 'GET',
response_headers=response_headers,
force_http=True)
return HttpResponseRedirect(url)
I need to download multiple files from S3, as a zip would be better. Can the mentioned method be modified and used. If not please suggest other method.
Okay here is a possible solution, it basically downloads each file and zips them into a folder, then returns this to the user.
Not sure if s3_template_path is the same for each file, but change this if neccessary
# python 3
import requests
import os
import zipfile
file_names = ['test.pdf', 'test2.pdf', 'test3.pdf']
# set up zip folder
zip_subdir = "download_folder"
zip_filename = zip_subdir + ".zip"
byte_stream = io.BytesIO()
zf = zipfile.ZipFile(byte_stream, "w")
for filename in file_names:
s3_template_path = queryset.values('file')
conn = boto.connect_s3('<aws access key>', '<aws secret key>')
bucket = conn.get_bucket('your_bucket')
s3_file_path = bucket.get_key(s3_template_path)
response_headers = {
'response-content-type': 'application/force-download',
'response-content-disposition':'attachment;filename="%s"'% filename
}
url = s3_file_path.generate_url(60, 'GET',
response_headers=response_headers,
force_http=True)
# download the file
file_response = requests.get(url)
if file_response.status_code == 200:
# create a copy of the file
f1 = open(filename , 'wb')
f1.write(file_response.content)
f1.close()
# write the file to the zip folder
fdir, fname = os.path.split(filename)
zip_path = os.path.join(zip_subdir, fname)
zf.write(filename, zip_path)
# close the zip folder and return
zf.close()
response = HttpResponse(byte_stream.getvalue(), content_type="application/x-zip-compressed")
response['Content-Disposition'] = 'attachment; filename=%s' % zip_filename
return response
