The following seems to work. The filename is the document ID (docID)
and an extention of .pdf. The first three characters of the docID are
hashed to create a directory tree.
class PdfviewController(BasePlusController):
def index(self, a, b, c, docID):
if auth:
path = os.path.join(g.pdfdocs_dir,a,b,c,docID + '.pdf')
f = open(path, 'rb')
content = f.read()
f.close()
response.headers['Content-Type'] = 'application/pdf'
return content
Thanks.
