开发的方法论与哲学
么样的应用程序，都不能信任用户的输入，除非输入已被处理过。恶意行
为者可能正在考虑入侵我们的服务器或盗取客户的数据，或以其他方式将
内容注入我们的网页。这些用户可能是应用程序的使用者甚至是内部员工，
因此在进行输入处理时，应该对所有人都一视同仁。
设身处地为接口使用者着想，是防止编写出不成熟的接口的最佳方法。你
可以进行这样的思考练习，停下来思考你希望如何使用一个接口，以及在
使用它时你可能需要用到的不同方式，那么最终你一定会编写出一个更好
的接口。这并不是说我们希望让接口使用者自己完成所有的事情，而是希
望让接口的调用变得尽可能简单，不烦琐。如果使用者在使用接口之后仍
然需要在代码中包含很长的业务逻辑块，我们就需要停下来问问自己 ：这
些业务逻辑是否应该由接口提供而不是放在接口外面？

构建、部署与运行
构建过程有多个方面。从宏观上来说，我们在共享逻辑中安装和编译资源，
以便运行时应用程序可以使用它们。这意味着在安装系统或应用程序依赖
项，将文件复制到不同的目录，编译为不同的语言，或将文件打包在一起时，
应用程序可能还有许多其他的需求。
要在开发、预发布和生产环境中成功地管理应用程序，关键是明确定义和
描述构建过程。这些常见环境以及其他你可能遇到的环境，都是用于特定
的目的的，你也可以从服务该目的的过程中获益。
在开发时，我们关注增强的调试工具、使用库的开发环境版本、源代码映
射和详细的日志记录级别。我们也依赖覆盖行为的自定义方式，以便可以
轻松模仿生产环境的样子，并且在可能的情况下 ...
