ツイストウェイのhttplib2

Question

httplib2パートを「ツイスト」に変換するにはどうすればよいですか？

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 

import httplib2 

import sys 

class JamesOptions(usage.Options): 
    optParameters = [ 
     ['outfile', 'o', None, 'Logfile [default: sys.stdout]'], 
     ['baudrate', 'b', 38400, 'Serial baudrate [default: 9600'], 
     ['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])) + 
      ",vrms:" + 
      str(decodeFloat(response.get("rf_data")[12:16])) + 
      ",irms:" + 
      str(decodeFloat(response.get("rf_data")[16:20])) + 
      "}") 

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

Answer 1

twisted.web.client.Agent().request()を使用してください。それはDeferredを返します。

詳細および例については、Agent howtoを参照してください。
