"Flask By Example(PACKT,2016)" 是一本关于使用Python微型框架Flask进行Web开发的实战教程。这本书引导读者从基础知识到构建完整的Web应用程序,通过三个实际项目帮助读者掌握Flask的核心概念。 在本书中,你将学习如何: 1. 构建基于Flask的三个Web应用:从零开始,逐步学习如何搭建动态展示最新新闻、货币汇率和天气信息的Headlines应用,管理用户提交的犯罪信息并绘制地图的Crime Map应用,以及整合Bootstrap和MongoDB数据库的Waiter Caller应用,用于餐厅顾客呼叫服务员。 2. 根据请求动态显示数据:理解如何根据用户的请求动态地提供信息,创建响应式的Web界面。 3. 使用数据库存储数据:学习如何在SQL(如MySQL)和NoSQL(如MongoDB)数据库中存储用户数据和静态数据,并将其应用于Web应用程序。 4. 结合前端技术:结合HTML、CSS和JavaScript,创建良好的用户体验,使网站更具吸引力和交互性。 5. 利用API服务:了解如何利用如OpenWeatherMap、Open Exchange Rates和bitly等免费API,为你的应用添加实用功能。 6. 扩展应用功能:通过引入Flask-Login,学习如何实现用户账户控制系统,增强应用的高级功能。 7. 确保Web应用安全:学习关于Web应用安全的知识,防范SQL注入和XSS(跨站脚本攻击)等常见攻击,确保用户数据的安全。 这本书适合对Python有一定基础,想要学习Web开发的读者,特别是希望通过实践来学习Flask框架的开发者。作者Gareth Dwyer通过实例引导,让读者在解决实际问题的过程中深入理解和掌握Flask的用法。尽管书中的内容可能随着时间的推移而有些过时,但Flask的基本原理和技术依然适用,对于初学者来说仍然是一个很好的起点。

What You Will Learn Build three web applications from the ground up using the powerful Python micro framework, Flask. Dynamically display data to your viewers, based on their requests Store user and static data in SQL and NoSQL databases and use this data to power your web applications Create a good user experience by combining HTML, CSS, and JavaScript Harness the convenience of freely available APIs, including OpenWeatherMap, Open Exchange Rates, and bitly Extend your applications to build advanced functionality, such as a user account control system using Flask-Login Learn about web application security and defend against common attacks, such as SQL injection and XSS In Detail This book will take you on a journey from learning about web development using Flask to building fully functional web applications. In the first major project, we develop a dynamic Headlines application that displays the latest news headlines along with up-to-date currency and weather information. In project two, we build a Crime Map application that is backed by a MySQL database, allowing users to submit information on and the location of crimes in order to plot danger zones and other crime trends within an area. In the final project, we combine Flask with more modern technologies, such as Twitter's Bootstrap and the NoSQL database MongoDB, to create a Waiter Caller application that allows restaurant patrons to easily call a waiter to their table. This pragmatic tutorial will keep you engaged as you learn the crux of Flask by working on challenging real-world applications. Style and approach This book will provide you with rich, practical experience of Flask. Every technology, that is employed along with Flask is comprehensively introduced, while the book focusses on developing web applications. Pointers to educational material are always given if you want to gain in-depth knowledge of the various technologies used. Table of Contents Chapter 1: Hello, World!
