问题 I'm running a django app using twisted. I moved now from http to https. How can I add redirects from http to https in twisted? 回答1: An easy way to generate redirects in Twisted Web is is with the Redirect resource. Instantiate it with a URL and put it into your resource hierarchy. If it is rendered, it will return a redirect response to that URL: from twisted.web.util import Redirect from twisted.web.resource import Resource from twisted.web.server import Site from twisted.internet import

问题 Closed . This question is opinion-based. It is not currently accepting answers. Want to improve this question? Update the question so it can be answered with facts and citations by editing this post. Closed 6 years ago . My idea is to build a simple chat application for iOS and Android. In any case, my question is related to the server-side. The best option to do a chat application, from what I've read, is to build a socket. Referring to the database, my intention is to use MySQL, which may

问题 I need run some multi-thread\multiprocessing work (because I have some library which uses blocking call) in Scrapy, and after its completion put back Request to Scrapy engine. I need something like this: def blocking_call(self, html): # .... # do some work in blocking call return Request(url) def parse(self, response): return self.blocking_call(response.body) How I can do that? I think I should to use Twisted reactor and Deferred object. But Scrapy parse callback must return only None or

问题 I'm planning up a discussion software using Python with Twisted, Storm, and Jinja. The problem is that Jinja was not made for Twisted or asynchronous socket libraries, and the performance provided by using Twisted is why I don't plan on using Flask. So, how can I have Twisted render webpages using Jinja? 回答1: You can render web pages using Jinja the same way you would use any other Python library in Twisted. You just call into it. This will work fine with Twisted, although you may run into

问题 I remember reading that the following features lead to the development of interesting frameworks/libraries in Python:- (I read the article from http://www.python.org/workshops/2002-02/papers/09/index.htm) A simple class model, which facilitates inheritance. Dynamic typing, which means that the code needs to assume less. Built-in memory management. Java is statically compiled, and it has a garbage collector too. I wonder if its class model can be termed simple, however, keeping in mind the

问题 All: I'm seeking input/guidance/and design ideas. My goal is to find a lean but reliable way to take XML payload from an HTTP POST (no problems with this part), parse it, and spawn a relatively long-lived process asynchronously. The spawned process is CPU intensive and will last for roughly three minutes. I don't expect much load at first, but there's a definite possibility that I will need to scale this out horizontally across servers as traffic hopefully increases. I really like the Celery

问题 I started using Twisted in a project that require asynchronous programming and the docs are pretty good. So my question is, is a Deferred in Twisted the same as a Promise in Javascript? If not, what are the differences? 回答1: The answer to your question is both Yes and No depending on why you're asking. Yes: Both a Twisted Deferred and a Javascript Promise implement a mechanism for queuing synchronous blocks of code to be run in a given order while being decoupled from other synchronous blocks

问题 I'm writing a Python application that needs both concurrency and asynchronicity. I've had a few recommendations each for Twisted and Celery, but I'm having trouble determining which is the better choice for this application (I have no experience with either). The application (which is not a web app) primarily centers around making SOAP calls out to various third party APIs. To process a given piece of data, I'll need to call several APIs sequentially. And I'd like to be able to have a pool of
