问题描述
我经常听到/阅读有关基于交互的编程的/阅读，但我并不完全清楚这意味着什么.是否基于接口的编程是一个实际的独立主题，实际上写了关于它的书籍?如果是这样，谁能推荐任何好的?
我遇到了基于接口的编程，因为我正在阅读有关API的设计方式，并希望更多地了解它.现在，我尚不清楚如何正确地设计界面周围的API.
任何信息都非常感谢.
推荐答案
基本上是用接口而不是具体类(或更糟糕的是静态方法)来表达您的依赖关系的问题.因此，如果您的一类需要执行身份验证，则应提供IAuthenticator(或其他).
这意味着:
- 您可以在实施实际依赖性之前编写代码
- 您可以非常轻松地通过嘲笑测试(不必嘲笑课程，这变得丑陋)
- 很明显，您在API而不是实现方面依赖什么(即您有更松散的耦合)

"实用的API设计"第6章Jaroslav Tulach 标题为"针对接口而不是实现的代码".它解释说，通过针对界面而不是特定的实现进行编码，您可以将模块(或组件)分解系统中，从而提高系统质量.
bertrand meyer in oosc2 清楚地解释了为什么"为什么"关闭"系统并使其更模块化提高其质量.

问题描述
I often hear/read about interfaced based programming but I am not exactly clear on what that really means. Is interfaced based programming an actual stand alone topic that actually has books written about it? If so, can anyone recommend any good ones?
I came across interface based programming as I was reading about how good APIs are designed and would like to learn more about it. Right now I am not clear how to properly go about designing an API around interfaces.
Any info is greatly appreciated.

It's basically a matter of expressing your dependencies in terms of interfaces instead of concrete classes (or worse, static methods). So if one of your classes needs to perform authentication, it should be provided an IAuthenticator (or whatever).
This means that:
- You can write your code before implementing the real dependency
- You can test via mocking really easily (without having to mock classes, which gets ugly)
- It's clear what you depend on in terms of the API instead of implementation (i.e. you have looser coupling)

Chapter 6 of "Practical API Design" by Jaroslav Tulach is titled "Code Against Interfaces, Not Implementations". It explains that, by coding against an interface rather than a specific implementation, you can decouple modules (or components) in a system and therefore raise the system quality.
Bertrand Meyer in OOSC2 explains clearly why "closing" a system and making it more modular raises its quality.
