Hi
I want to connect to internal http services with django and I need to
buffer the output the http response of those services because some contents
are very large.
I am using python 3.6, django 2.0, `http.client` and the following code:
class HTTPStreamIterAndClose():
def __init__(self, conn, res, buffsize):
self.conn = conn
self.res = res
self.buffsize = buffsize
self.length = 1
bytes_length = int(res.getheader('Content-Length'))
if buffsize < bytes_length:
self.length = math.ceil(bytes_length/buffsize)
def __iter__(self):
return self
def __next__(self):
buff = self.res.read(self.buffsize)
if buff is b'':
self.res.close()
self.conn.close()
raise StopIteration
else:
return buff
def __len__(self):
return self.length
def passthru_http_service(request, server, timeout, path):
serv = HTTPService(server, timeout)
res = serv.request(path)
response = StreamingHttpResponse(
HTTPStreamIterAndClose(serv.connection, res, 200),
content_type='application/json'
)
response['Content-Length'] = res.getheader('Content-Length')
return response
And the reponse is empty, I test the iterator with:
b''.join(HTTPStreamIterAndClose(serv.connection, res, 200)
And everything works fine, I don't know why is not working in the Django
response.
Cheers
