I have been battling this problem and I finally figured out what is
going on.
I have a method in my controller which returns some automatically
generated csv data, like this:
@expose()
def export(self, **kw):
r = 'asdf,asdf,asdf'
response = pylons.response
response.headers['content-type'] = "application/csv"
response.headers['Content-Transfer-Encoding'] = 'Binary'
response.headers['Content-length'] = len(r)
response.headers['Content-Disposition'] = 'attachment;
filename=\"mygenerated.csv\"'
response.headers['Connection'] = "close"
return r
The problem is that when the response is sent back to the server, the
content-type returns to 'text/html' which causes Safari to add an
extra ".html" to the file when it downloads:
#the header response from the server
Server PasteWSGIServer/0.5 Python/2.5.1
Date Wed, 07 May 2008 15:59:25 GMT
Pragma no-cache
Cache-Control no-cache
Content-Transfer-Encoding Binary
content-disposition attachment; filename="mygenerated.csv"
Connection close
Content-Type text/html; charset=utf-8
Content-Length 14
This is not desirable. Perhaps we need to define what the content
type is and pass that to the expose decorator? Why won't my header
setting "stick"?
cheers.
