Hur ska jag göra för att få det här att funka, det här exemplet tog jag från xmlrpc2scgi.py, den fil jag försöker kommunicera via. de säga att jag ska göra så här:
så här ser min kod ut:
The following is an exmple of how to use this class.
rtorrent_host='http://localhost:33000'
rtc = RTorrentXMLRPCClient(rtorrent_host)
for infohash in rtc.download_list('complete'):
if rtc.d.get_ratio(infohash) > 500:
print "%s has a ratio of over 0.5"%(rtc.d.get_name(infohash))
Kod: Markera allt
#! /usr/bin/python
import xmlrpc2scgi
rtorrent_host='scgi:192.168.0.1:6882'
rtc = xmlrpc2scgi.RTorrentXMLRPCClient(rtorrent_host)
for infohash in rtc.download_list('complete'):
if rtc.d.get_ratio(infohash) > 500:
print "%s has a ratio of over 0.5"%(rtc.d.get_name(infohash))Jag får detta felmeddelande:
Jag försöker göra om skriptet.sh i denna http://ubuntu-se.org/phpBB3/viewtopic.php?f=19&t=30454 till python, inte för att det är fel på den utan för att jag tyckte att det skulle vara ett roligt sätt att lära sig på.Traceback (most recent call last):
File "rtorrentpyt.py", line 7, in <module>
for infohash in rtc.download_list('complete'):
File "/home/jonas/rtorrent_rpc/xmlrpc2scgi.py", line 178, in __call__
xmlresp = SCGIRequest(self.url).send(xmlreq)
File "/home/jonas/rtorrent_rpc/xmlrpc2scgi.py", line 111, in send
scgiresp = self.__send(self.add_required_scgi_headers(data))
File "/home/jonas/rtorrent_rpc/xmlrpc2scgi.py", line 98, in __send
sock.connect(path)
File "<string>", line 1, in connect
socket.error: (2, 'No such file or directory')
Men jag kommer inte så långt...
Det är inte omöjligt att jag gör helt fel så kom gärna med förslag Jag ska kommunicera med en rpc.socket med rTorrent via xmlrpc2scgi.py. Här är filen jag försöker kommunicera med:
