商品描述

Explore Twisted, the Python-based event-driven networking engine, and review several of its most popular application projects. It is written by community leaders who have contributed to many of the projects covered, and share their hard-won insights and experience.

Expert Twisted starts with an introduction to event-driven programming, explaining it in the context of what makes Twisted unique. It shows how Twisted's design emphasizes testability as a solution to common challenges of reliability, debugging, and start-to-finish causality that are inherent in event-driven programming. It also explains asynchronous programming, and the importance of functions, deferreds, and coroutines. It then uses two popular applications, treq and klein, to demonstrate calling and writing Web APIs with Twisted.

The second part of the book dives into Twisted projects, in each case explaining how the project fits into the Twisted ecosystem and what it does, and offers several examples to bring readers up to speed, with pointers to additional resources for more depth. Examples include using Twisted with Docker, as a WSGI container, for file sharing, and more.

What You'll Learn
  • Integrate Twisted and asyncio using adapters
  • Automate software build, test, and release processes with Buildbot
  • Create clients and servers with Autobahn
  • Transfer files with Magic Wormhole
  • Distribute cloud-based file storage with Tahoe LAFS
  • Understand HTTP/2 with Python and Twisted
  • Support for asynchronous tasks using Django Channels

Who This Book Is For

Readers should have some Python experience and understand the essentials of containers and protocols, but need not be familiar with Twisted or the associated projects covered in the book.

商品描述(中文翻譯)

探索 Twisted，這是一個基於 Python 的事件驅動網路引擎，並回顧幾個最受歡迎的應用專案。這本書由社群領袖撰寫，他們對許多涵蓋的專案做出了貢獻，並分享了他們辛苦獲得的見解和經驗。

《Expert Twisted》首先介紹事件驅動編程，並在 Twisted 獨特性的背景下進行解釋。它展示了 Twisted 的設計如何強調可測試性，以解決事件驅動編程中固有的可靠性、除錯和從頭到尾的因果關係等常見挑戰。它還解釋了非同步編程，以及函數、延遲（deferreds）和協程（coroutines）的重要性。接著，它使用兩個流行的應用程式，treq 和 klein，來演示如何使用 Twisted 調用和編寫 Web API。

本書的第二部分深入探討 Twisted 專案，逐一解釋每個專案如何融入 Twisted 生態系統及其功能，並提供幾個範例以幫助讀者快速上手，並指向更多資源以獲得更深入的了解。範例包括使用 Twisted 與 Docker、作為 WSGI 容器、進行檔案共享等。

**你將學到的內容**
- 使用適配器整合 Twisted 和 asyncio
- 使用 Buildbot 自動化軟體建置、測試和發佈流程
- 使用 Autobahn 創建客戶端和伺服器
- 使用 Magic Wormhole 傳輸檔案
- 使用 Tahoe LAFS 分配雲端檔案儲存
- 使用 Python 和 Twisted 理解 HTTP/2
- 使用 Django Channels 支援非同步任務

**本書適合誰閱讀**
讀者應具備一定的 Python 經驗，並理解容器和協議的基本概念，但不需要熟悉 Twisted 或書中涵蓋的相關專案。
