Hi,
I have been trying to use the 'ryu.app.ofctl_rest
<https://ryu.readthedocs.io/en/latest/app/ofctl_rest.html#id10>' interface.
Using cURL is fine. Take the following drop rule for example, works fine.
curl -X POST -d "{'dpid': '69133577248', 'cookie': 1, 'cookie_mask': 1,
'table_id': 0, 'idle_timeout': 0, 'hard_timeout': 0, 'priority': 0,
'flags': 1, 'match': {'in_port': 3}, 'actions': []}"
http://198.8.8.235:8080/stats/flowentry/add
Now taking the exact same dictionary and URL I try to apply the rul via
python3 urllib. Here is the code snippet. I print out the encoded data to
check it. It fails with a 400 error:
*flow = {'dpid': '69133577248', 'cookie': 1, 'cookie_mask': 1, 'table_id':
0, 'idle_timeout': 0, 'hard_timeout': 0, 'priority': 0, 'flags': 1,
'match': {'in_port': 3}, 'actions': []}*
*url = http://198.8.8.235:8080/stats/flowentry/add
<http://198.8.8.235:8080/stats/flowentry/add>*
*data = urllib.parse.urlencode(flow).encode('utf-8')*
*print('ENCODED DATA -->', data)*
*with urllib.request.urlopen(url, data) as response:*
* print (response.read().decode('utf-8'))*
ENCODED DATA -->
b'dpid=69133577248&cookie=1&cookie_mask=1&table_id=0&idle_timeout=0&hard_timeout=0&priority=0&flags=1&match=%7B%27in_port%27%3A+3%7D&actions=%5B%5D'
