Python Klein - Non Blocking API

由 百般思念 提交于 2020-02-05 03:28:10
问题 Need help with Klein API for Non-blocking. This is a simple test app: # -*- coding: utf-8 -*- import datetime import json import time from klein import Klein app = Klein() async def delay(seconds): """Set some delay for test""" time.sleep(seconds) return "Works" @app.route('/', branch=True) async def main(request): some_data = await delay(5) return json.dumps([{ "status": "200", "time": datetime.datetime.now().strftime("%Y-%m-%d %H:%M:%S"), "data": some_data }]) app.run("localhost", 8080)

Twisted Python, TLS and client/server certificate authentication error

由 蓝咒 提交于 2020-02-04 06:01:11
问题 I've been learning Twisted as best I can, but together with limited TLS knowledge it's proving challenging. I'm trying to write (ultimately) an SMTP server that can send and receive messages both as plain text, or via TLS depending on requirements of a specific message to be sent / received. My sample server code (thus far, just handling the TLS connection, no SMTP bits yet!) is borrowed from http://twistedmatrix.com/documents/11.0.0/core/howto/ssl.html#auto5 and looks like: from OpenSSL

setsockopt before connect for reactor.connectTCP

由 十年热恋 提交于 2020-01-25 20:23:50
问题 I have a small python client which needs a setsockopt after create_socket, but before connect. The non-twisted python code is as follows. How can this be expressed in a twisted environment? create_socket (socket.AF_INET, socket.SOCK_STREAM) socket.setsockopt(socket.IPPROTO_IP, 24,1) socket.bind((clientip, 0)) connect ((serverip,serverport)) 回答1: In twisted you can use the reactor.adoptStreamPort : s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) socket.setsockopt(socket.IPPROTO_IP, 24,1)

How to build kivy and Twisted in Buildozer

由 痞子三分冷 提交于 2020-01-25 08:24:46
问题 I am working on my first app, and I added twisted to the app via the kivy support function kivy.support.install_twisted_reactor. It works well in my development environment, but I can't get my buildozer settings right to get twisted to compile properly with the app. Any ideas as to which minimum settings are mandatory to get buildozer to compile twisted properly? I tried simply adding "twisted" to the requirements section, but clearly that's not enough... I could share my code, but I am

Multiple responses in Twisted

由 冷暖自知 提交于 2020-01-24 15:54:05
问题 I'm trying to develop simple TCP , clinet/server game using Twisted and Pygame, but I have difficulties with sending data to clients. Twisted doesn't allow me to send multiple responses in a row. That's what I'm trying to do: I have method witch handle player status changes and resend them to other clients: def handle_stateChanged(self, data): #get playerState from client and override local copy of player #check if all players are ready #if needed, change gameState form 'inLOBBY' to 'inGAME'

How to properly stop Twisted reactor when callback is finished

由 回眸只為那壹抹淺笑 提交于 2020-01-24 13:21:07
问题 I am still very new to Python, but I have a grasp on the basics. I am trying to write a script that will allow me to interface with Deluge's API. Right now I am just trying to get the current download queue back, but the reactor keeps running. If I put reactor.stop() at the end of Deluge().onGetSessionState() then the reactor stops before Deluge().onGetTorrentStatus() comes back. I'm confused on how to handle stopping the reactor when onGetSessionState gets everything it needs from

How to combine callLater and addCallback?

由 旧巷老猫 提交于 2020-01-22 17:57:06
问题 This is so broken, I hope you are merciful with me: reactor.callLater(0, myFunction, parameter1).addCallback(reactor.stop) reactor.run() myFunction returns a deferred. I hope it is clear what I want to do: as soon as the reactor is running, I want to call myFunction . That is why I am using 0 as the delay parameter. Is there no other way except callLater? It looks funny to pass it a delay of 0. I want to stop the reactor as soon as myFunction has completed the task. The problems that I have

Twisted.Web and AJAX

Python pip安装Scrapy，报错Twisted

由 旧街凉风 提交于 2020-01-21 15:48:45
Scrapy依赖的包有如下： lxml：一种高效的XML和HTML解析器 w3lib：一种处理URL和网页编码多功能辅助 twisted：一个异步网络框架 cryptography 和 pyOpenSSL：处理各种网络级安全需求 —————————————————————————— 1.先运行一次pip安装 pip install Scrapy 2.安装完一次过后，基本除了报错twisted没安装成功以外，其他依赖包应该是安装好了。 然后自行下载twisted，注意：要对应你的python版本号和电脑系统的位数 我用的是python37，系统64位的。 https://www.lfd.uci.edu/~gohlke/pythonlibs/ 3.下载后，pip安装 pip install [文件路径]\Twisted-18.9.0-cp37-cp37m-win_amd64.whl 4.最后再运行一次Scrapy的pip安装就可以安装成功了。 ———————————————— 版权声明：本文为CSDN博主「Sagittarius32」的原创文章，遵循 CC 4.0 BY-SA 版权协议，转载请附上原文出处链接及本声明。 原文链接：https://blog.csdn.net/sagittarius32/article/details/85345142 来源： https://www
