问题 have this code who run scrapy crawler from script(http://doc.scrapy.org/en/latest/topics/practices.html#run-scrapy-from-a-script). But it doesn't work. from twisted.internet import reactor from scrapy.crawler import Crawler from scrapy import log,signals from spiders.egov import EgovSpider from scrapy.utils.project import get_project_settings def run(): spider =EgovSpider() settings = get_project_settings() crawler = Crawler(settings) crawler.signals.connect(reactor.stop, signal=signals

问题 I have some code which looks something like this: def run(spider_name, settings): runner = CrawlerProcess(settings) runner.crawl(spider_name) runner.start() return True I have two py.test tests which each call run(), when the second test executes I get the following error. runner.start() ../../.virtualenvs/scrape-service/lib/python3.6/site-packages/scrapy/crawler.py:291: in start reactor.run(installSignalHandlers=False) # blocking call ../../.virtualenvs/scrape-service/lib/python3.6/site

问题 I have a autobahn twisted websocket running in python which is working in a dev vm correctly but I have been unable to get working when the server is running in openshift. Here is the shortened code which works for me in a vm. from autobahn.twisted.websocket import WebSocketServerProtocol, WebSocketServerFactory, listenWS from autobahn.twisted.resource import WebSocketResource class MyServerProtocol(WebSocketServerProtocol): def onConnect(self, request): stuff... def onOpen(self): stuff...

问题 Inside a Twisted Resource, I am returning a json encoded dict as the response var below. The data is a list of 5 people with name, guid, and a couple other fields less than 32 characters long each, so not a ton of data. I get this OverflowError exception pretty often, but I don't quite understand what the unsupported utf-8 sequence length refers to. self.request.write(ujson.dumps(response)) exceptions.OverflowError: Unsupported UTF-8 sequence length when encoding string 回答1: When in doubt,

问题 I am generating a template for an image gallery page. My approach is as follows: Host the images from a sub directory of an images folder The image folder will be titled the same as the gallery title The view passes a list of filenames to the template The template loops through the list and creates img tags So my view would be def some_gallery(request): #LOGIC TO GET A LIST OF FILENAMES variables = RequestContext(request,{ 'user' : request.user, 'title' : 'something', 'files' : fileList })

问题 I'm trying to use this class provided by twisted to frame my tcp stream. But the default format they have is in big endian byte order but I need to read in little endian. So I did: class Player(basic.Int16StringReceiver): structFormat = "<H" def stringReceived(self, packet): print ':'.join(x.encode('hex') for x in packet) But for some reason stringReceived seldom gets called. Both client and server is on the same machine and I am very sure the client did send the data. So why is
