httplib2 sur la voie déformée

Question

Comment convertir la partie httplib2 de manière "tordue"?

from twisted.python import log, usage 
from twisted.internet import reactor 
from twisted.internet.serialport import SerialPort 
from twisted.web.client import Agent 

from struct import unpack

     ['port', 'p', '/dev/tty.usbserial-A600ezgH', 'Serial Port device'], 
    ] 

class XbeeLogger: 
    def decodeFloat(self, var): 
     text = "" 
     for i in range(0, len(var)): 
      text += var[i] 
     return unpack('f', text)[0] 

    def handle_packet(self, *args): 
     response = self._split_response(args) 
     h = httplib2.Http() 
     resp, content = h.request(
      "http://localhost/emoncms2/api/post?apikey=2c0915af95786b73d841da00da68b5fa&json={real_power:" + 
      str(decodeFloat(response.get("rf_data")[0:4])) + 
      ",apparent_power:" + 
      str(decodeFloat(response.get("rf_data")[4:8])) + 
      ",power_factory:" + 
      str(decodeFloat(response.get("rf_data")[8:12])) +

      "}") 

if __name__ == '__main__': 
    o = JamesOptions() 
    try: 
     o.parseOptions() 
    except usage.UsageError, errortext: 
     print '%s: %s' % (sys.argv[0], errortext)

     raise SystemExit, 1 

    logFile = o.opts['outfile'] 
    if logFile is None: 
     logFile = sys.stdout 
    log.startLogging(logFile) 

    from xbeeService.protocol import ZigBeeProtocol 
    class XbeeTest(ZigBeeProtocol, XbeeLogger): 
     pass 

    port = o.opts['port'] 
    log.msg('Attempting to open %s at %dbps as a %s device' % (port, o.opts['baudrate'], ZigBeeProtocol.__name__)) 
    s = SerialPort(XbeeTest(), o.opts['port'], reactor, baudrate=o.opts['baudrate']) 
    reactor.run()

Utilisez twisted.web.client.Agent().request(). Il renverra un Deferred. Pour plus de détails et d'exemples, voir le Agent howto.
