Question

我需要将文件从扭曲的应用程序中放入Google的云存储中。

我一直在使用亚马逊和txAWS，但现在我正在使用GCS我不确定是否存在可以让我这样做的事情吗？

是否可以将txAWS与GCS一起使用？这听起来像一个奇怪的问题但是可以将boto S3Connection与GCS一起使用，所以也许可以通过txAWS来做同样的事情。？

我建议将Twisted Web client与GCS JSON API一起使用。以下是列出存储桶内容的示例：

import json
from twisted.internet import reactor
from twisted.internet.defer import Deferred
from twisted.internet.protocol import Protocol
from twisted.web.client import Agent
from twisted.web.error import Error
from twisted.web.http_headers import Headers

GCS_BASE_URL = 'https://www.googleapis.com/storage/v1beta1'
GCS_API_KEY = '<your-api-key>'
GCS_BUCKET = '<your-bucket>'

class ResponseAccumulate(Protocol):
    def __init__(self, finished):
        self.finished = finished
        self.fullbuffer = ''

    def dataReceived(self, bytes):
        print 'Received %d bytes.' % len(bytes)
        self.fullbuffer += bytes

    def connectionLost(self, reason):
        if isinstance(reason, Error):
            print 'Finished receiving body:', reason.getErrorMessage()
        else:
            parsed = json.loads(self.fullbuffer)
            print 'Bucket contents:'
            for item in parsed['items']:
              print ' ', item['id']
        self.finished.callback(None)

agent = Agent(reactor)

d = agent.request(
    'GET',
    '%s/b/%s/o?key=%s' % (GCS_BASE_URL, GCS_BUCKET, GCS_API_KEY),
    Headers({'User-Agent': ['Twisted Web Client Example']}),
    None)

def cbResponse(response):
    print 'Response received', response.code
    finished = Deferred()
    response.deliverBody(ResponseAccumulate(finished))
    return finished
d.addCallback(cbResponse)

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

reactor.run()

从Twisted上传到GCS
