问题 I am learning scrapy and am having a hard time trying to figure out this issue. My spider will not crawl the macys website and keeps throwing the following error: [<twisted.python.failure.Failure twisted.internet.error.ConnectionLost: Connection to the other side was lost in a non-clean fashion: Connection lost.>] Things I've tried so far: Setting headers and robotstxt obey per this thread: Scrapy Shell: twisted.internet.error.ConnectionLost although USER_AGENT is set Changing the user agent

问题 I'm trying to read from file over ISFTPFile and I want to avoid using @inlinceCallbacks in this scenario? Or maybe there is a better way to read/write for ISFTPFile ? @defer.inlineCallbacks def calculate_checksum(open_file): hasher = hashlib.sha256() offset = 0 try: while True: d = yield open_file.readChunk(offset, chunk_size) offset += chunk_size hasher.update(d) except EOFError: pass target_checksum = hasher.hexdigest() defer.returnValue(target_checksum) client_file = client.openFile(

问题 Using Python 2.6, Twisted 10.1, and GTK+ 2.22, with latest pygtk installed, I'm having problems on shutdown. When I close my application and shut down the reactor (using the gtk2reactor of course), the application simply freezes. I've poked around the twisted source and added debug messages. What ends up happening is, the 'shutdown' event fires, PortableGtkReactor.crash is called, which calls gtk.main_quit . The event gets processed at the end of ReactorBase.runUntilCurrent . When the

问题 How do I call an autobahn/wamp/twisted protocol publish method from outside of the protocol class? I have a custom python autobahn client based on https://github.com/tavendo/AutobahnPython/blob/master/examples/wamp/pubsub/custom/client.py. I am attempting to publish an event from outside of the custom WampClientProtocol class and am having trouble. If I assign the protcol object to a variable, line 1387 of wamp.py (https://github.com/tavendo/AutobahnPython/blob/master/autobahn/autobahn/wamp

问题 I've just discovered Twisted in Python, and have been looking at the echoserv_ssl.py sample as found here: https://twistedmatrix.com/documents/14.0.0/core/howto/ssl.html. Just above the sample code, the page quotes "The following examples rely on the files server.pem (private key and self-signed certificate together) and public.pem (the server’s public certificate by itself)." So being something of a novice when it comes to SSL certs and keys, I did some research, and found http://www

问题 I'm trying to use Twisted with Python2.7 for piping two processes. What I'd like to do is: myImagesPipesGenerator | ffmpeg -i - myImagesPipesGenerator is outputing on stdout an infinite list of BMP images. FFmpeg is getting those pictures on stdin and encoding them in a video So I need to: generatorTransport = reactor.spawnProcess(myInputProtocol, "myImagesPipesGenerator", ["myImagesPipesGenerator",], env=None, childFDs={0:'w', 1:'r', 2:'r'}) ffmpegTransport = reactor.spawnProcess

问题 I'm trying to modify my simple Twisted web proxy to use "Proxy-Authentication" (username/password) instead of the current IP based authentication. Problem is, I'm new to Twisted and don't even know where to start. Here is my Factory Class. class ProxyFactory(http.HTTPFactory): def __init__(self, ip, internal_ips): http.HTTPFactory.__init__(self) self.ip = ip self.protocol = proxy.Proxy self.INTERNAL_IPS = internal_ips def buildProtocol(self, addr): print addr # IP based authentication -- need

问题 I have a twisted server using SSL sockets and using certificates to identify the different clients that connect to the server. I'd like to enforce the state where there is only one connection by each possible id. The two ways I can think of is to keep track of connected ids and then not allow a second connection by the same id or allow the second connection and immediately terminate the first. I'm trying to do the later but am having some issues (I'll explain my choice at the end) I'm storing
