twisted bekommen Körper der POST Anfrage

Alle Recht, so ist es ebenso einfach wie das aufrufen request.content.read(). Diese, so weit wie ich sagen kann, ist nicht dokumentiert, in der API.

Hier ist der aktualisierte code für den client:

from twisted.internet import reactor
from twisted.web.client import Agent
from twisted.web.http_headers import Headers

from twisted.web.client import FileBodyProducer
from twisted.internet.defer import Deferred
from twisted.internet.protocol import Protocol
from pprint import pformat

class BeginningPrinter(Protocol):
    def __init__(self, finished):
        self.finished = finished
        self.remaining = 1024 * 10

    def dataReceived(self, bytes):
        if self.remaining:
            display = bytes[:self.remaining]
            print 'Some data received:'
            print display
            self.remaining -= len(display)

    def connectionLost(self, reason):
        print 'Finished receiving body:', reason.getErrorMessage()
        self.finished.callback(None)

class SaveContents(Protocol):
    def __init__(self, finished, filesize, filename):
        self.finished = finished
        self.remaining = filesize
        self.outfile = open(filename, 'wb')

    def dataReceived(self, bytes):
        if self.remaining:
            display = bytes[:self.remaining]
            self.outfile.write(display)
            self.remaining -= len(display)
        else:
            self.outfile.close()

    def connectionLost(self, reason):
        print 'Finished receiving body:', reason.getErrorMessage()
        self.outfile.close()
        self.finished.callback(None)

agent = Agent(reactor)
f = open('70935-new_barcode.pdf', 'rb')
body = FileBodyProducer(f)
d = agent.request(
    'POST',
    'http://127.0.0.1:8080?filename=test.pdf',
    Headers({'User-Agent': ['Twisted Web Client Example'],
             'Content-Type': ['multipart/form-data; boundary=1024'.format()]}),
    body)

def cbRequest(response):
    print 'Response version:', response.version
    print 'Response code:', response.code
    print 'Response phrase:', response.phrase
    print 'Response headers:'
    print 'Response length:', response.length
    print pformat(list(response.headers.getAllRawHeaders()))
    finished = Deferred()
    response.deliverBody(SaveContents(finished, response.length, 'test2.pdf'))
    return finished
d.addCallback(cbRequest)

def cbShutdown(ignored):
    reactor.stop()
d.addBoth(cbShutdown)

reactor.run()

Und hier ist der server:

from twisted.web import server, resource
from twisted.internet import reactor
import os

# multi part encoding example: http://marianoiglesias.com.ar/python/file-uploading-with-multi-part-encoding-using-twisted/
class Simple(resource.Resource):
    isLeaf = True
    def render_GET(self, request):
        return "{0}".format(request.args.keys())
    def render_POST(self, request):
        with open(request.args['filename'][0], 'wb') as fd:
            fd.write(request.content.read())
        request.setHeader('Content-Length', os.stat(request.args['filename'][0]).st_size)
        with open(request.args['filename'][0], 'rb') as fd:
            request.write(fd.read())
        request.finish()
        return server.NOT_DONE_YET

site = server.Site(Simple())
reactor.listenTCP(8080, site)
reactor.run()

Kann ich jetzt schreiben den Inhalt der Datei habe ich erhalten, und Lesen Sie die Ergebnisse zurück.

wenn Sie wollen eine einfache POST mit dem Körper (nicht eine Datei) können Sie wie folgt tun

import urllib
from twisted.internet import protocol
from twisted.internet import defer
from twisted.web.http_headers import Headers
from twisted.internet import reactor
from twisted.web.client import Agent
from twisted.web.iweb import IBodyProducer
from zope.interface import implements
from twisted.internet.defer import succeed

class StringProducer(object):
    implements(IBodyProducer)

    def __init__(self, body):
        self.body = body
        self.length = len(body)

    def startProducing(self, consumer):
        consumer.write(self.body)
        return succeed(None)

    def pauseProducing(self):
        pass

    def stopProducing(self):
        pass

class SimpleReceiver(protocol.Protocol):
    def __init__(self, d):
        self.buf = ''; self.d = d

    def dataReceived(self, data):
        self.buf += data

    def connectionLost(self, reason):
        self.d.callback(self.buf)

def httpRequest(url, values=None, headers=None, method='POST'):

    agent = Agent(reactor)
    data = urllib.urlencode(values) if values else None

    d = agent.request(method, url, Headers(headers) if headers else {},
        StringProducer(data) if data else None
        )

    def handle_response(response):
        if response.code == 204:
            d = defer.succeed('')
        else:
            d = defer.Deferred()
            response.deliverBody(SimpleReceiver(d))
        return d

    d.addCallback(handle_response)
    return d

Jetzt oben im echten code kann man also

d = httpRequest('htpp://...', post_data_as_dictionary, some_headers, 'POST')
d.addCallback(your_ok_callback_function)
d.addErrback(your_errorback_function)

Beispiel-Header Aussehen sollte

headers = {'Accept' : ['application/json',],
            'Content-Type': ['application/x-www-form-urlencoded',] 
}

Ich hoffe, das hilft
