> Since version 1.22, streaming is the default method used by web2py to serve files from the following directories: [web2py working folder]/application/[your app]/static/ [web2py working folder]/application/[your app]/uploads/ > For customised file serving function that overrides the default download behavior, web2py will automatically detect whether the returning object is a streaming object (an iterator), or a string object, and serve accordingly. Examples: # streams big file using default byte size for chunks def my_big_file_downloader(): ... ... import os filename=request.args[0] pathfilename=os.path.join(request.folder,'uploads/', filename) return response.stream(open(pathfilename,'rb'), chunk_size=10**6) # the old way def my_small_file_downloader(): ... import os import gluon.contenttype filename=request.args[0] response.headers['Content-Type']=gluon.contenttype.contenttype(filename) pathfilename=os.path.join(request.folder,'uploads/', filename) return open('pathfilename', 'rb').read() You call them with: http://[host]/[app]/[controller]/my_big_file_downloader/[filename in uploads] or http://[host]/[app]/[controller]/my_big_file_downloader/[filename in uploads]/[...] where [...] is the filename you want the downloading user to see.
