A new ecore module: ecore_con
It's now super easy to perform various network task in a full efl fashion. Implemented "Lookup" for dns query and "Url" to perform http requests. "Server" will come soon. Comes with quite complete docs, examples and unit tests

:class:`efl.ecore_con.Lookup` class to perform DNS requests, the
|

:class:`efl.ecore_con.Url` class to perform HTTP requests and the
|

###########################
|
||||
|
||||
The ecore_con module provide various utilities to perform different network
|
||||
related tasks. Everything in a full async ecore way. Most notable are the
|
||||
:class:`Lookup` class to perform DNS requests, the :class:`Url` class to
|
||||
perform HTTP requests and the :class:`Server` class to implement your own
|
||||
server.
|
||||
|
||||
Don't forget about the :class:`efl.ecore.FileDownload` class if what you need
|
||||
is just to fetch some data to file.

|

|
||||
Utility class to make it easy to perform http requests (POST, GET, etc).
|
||||
|
||||
.. versionadded:: 1.17
|
||||
|
||||
Brief usage:
|
||||
1. Create an :class:`Url` object with ecore_con.Url('myurl')
|
||||
2. Register object callbacks using :func:`on_complete_event_add`,
|
||||
:func:`on_progress_event_add` and :func:`on_data_event_add` to
|
||||
receive the response, e.g. for HTTP/FTP downloads.
|
||||
3. Perform the operation with :func:`get`, :func:`head` and :func:`post`
|
||||
|
||||
If it's necessary use the :attr:`url` property. to change the object url.
|
||||
|
||||
.. note::
|
||||
It is good practice to reuse :class:`Url` objects wherever possible,
|
||||
but bear in mind that each one can only perform one operation at a
|
||||
time. You need to wait for the complete event before re-using or
|
||||
destroying the object.
|
||||
|
||||
.. warning::
|
||||
It is **really important** to call the :func:`delete()` method as soon
|
||||
as you have finished with your object, as it automatically remove all
|
||||
the registered events for you, that will otherwise continue to use
|
||||
resources.
|
||||
|
||||
Basic usage examples::
|
||||
|
||||
# HTTP GET
|
||||
u = ecore.Url("http://www.google.com")
|
||||
u.get()
|
||||
|
||||
# HTTP POST
|
||||
u = ecore.Url('https://httpbin.org/post')
|
||||
u.post(b'my data to post', 'text/txt')
|
||||
|
||||
# FTP download
|
||||
u = ecore.Url("ftp://ftp.example.com/pub/myfile")
|
||||
u.get()
|
||||
|
||||
# FTP upload as ftp://ftp.example.com/file
|
||||
u = ecore.Url("ftp://ftp.example.com")
|
||||
u.ftp_upload("/tmp/file", "user", "pass", None)
|
||||
|
||||
# FTP upload as ftp://ftp.example.com/dir/file
|
||||
u = ecore.Url("ftp://ftp.example.com")
|
||||
u.ftp_upload("/tmp/file", "user", "pass", "dir")
|
||||
|
||||
To actually make something usefull with your request you will need to
|
||||
connect the :class:`EventUrlComplete`, :class:`EventUrlProgress` and
|
||||
:class:`EventUrlData` events using the :func:`on_complete_event_add` and
|
||||
friends functions.
|
||||
|
||||
A more complete example::
|
||||
|
||||
from efl import ecore
|
||||
|
||||
def on_data(event):
|
||||
print("data: " + str(event.data[:80]))
|
||||
# do something here with the received data
|
||||
|
||||
def on_progress(event):
|
||||
# print(event)
|
||||
print("received %d on a total of %d bytes" % (
|
||||
event.down_now, event.down_total))
|
||||
|
||||
def on_complete(event):
|
||||
# print(event)
|
||||
print("http result: %d" % event.status)
|
||||
print("Total received bytes: %d" % event.url.received_bytes)
|
||||
|
||||
u.delete() # don't forget to delete !!
|
||||
|
||||
u = ecore.Url('http://www.google.com', verbose=False)
|
||||
u.on_data_event_add(on_data)
|
||||
u.on_progress_event_add(on_progress)
|
||||
u.on_complete_event_add(on_complete)
|
||||
u.get()
|
||||
|
||||
ecore.main_loop_begin()
|
||||
|
||||
If you need to save the received data to a file use the :attr:`fd`
|
||||
property, as::
|
||||
|
||||
fd = open('/tmp/tmpMxBtta', 'w')
|
||||
u = ecore.Url('http://example.com', fd=fd.fileno())
|
||||
u.get()
|
||||
|
||||
.. seealso::
|
||||
If you just need to download a file please consider using the
|
||||
simpler :class:`efl.ecore.FileDownload` class instead.
|
||||
|
||||
.. seealso::
|
||||

:func:`url_pipeline_get` to enable HTTP 1.1 pipelining.
