一般来说，框架作品是真实的或概念性的结构，旨在作为建筑的支撑或指南，将结构扩展为有用的东西……

一个简单的解释是:框架是一个可以围绕它构建应用程序的支架。

A framework generally provides some base functionality which you can use and extend to make more complex applications from, there are frameworks for all sorts of things. Microsofts MVC framework is a good example of this. It provides everything you need to get off the ground building website using the MVC pattern, it handles web requests, routes and the like. All you have to do is implement "Controllers" and provide "Views" which are two constructs defined by the MVC framework. The MVC framework then handles calling your controllers and rendering your views.

也许不是最好的措辞，但我希望它有帮助

我不确定“框架”是否有一个明确的定义。有时，一组很大的库被称为框架，但我认为这个词的典型用法更接近于aioobe带来的定义。

这篇非常好的文章总结了一组库和一个框架之间的区别:

框架可以定义为一组库，它们说“不要给我们打电话，我们会给你打电话”。

框架如何帮助您?因为您不需要从头开始编写一些东西，基本上只需扩展一个给定的工作应用程序。通过这种方式，您可以获得很高的生产率——有时最终得到的应用程序可能比您在相同时间内自己所做的要复杂得多——但您通常会牺牲很多灵活性。

维基百科(软件框架)的摘要(第一个谷歌点击顺便说一下)解释得很好:

A software framework, in computer programming, is an abstraction in which common code providing generic functionality can be selectively overridden or specialized by user code providing specific functionality. Frameworks are a special case of software libraries in that they are reusable abstractions of code wrapped in a well-defined Application programming interface (API), yet they contain some key distinguishing features that separate them from normal libraries. Software frameworks have these distinguishing features that separate them from libraries or normal user applications: inversion of control - In a framework, unlike in libraries or normal user applications, the overall program's flow of control is not dictated by the caller, but by the framework.[1] default behavior - A framework has a default behavior. This default behavior must actually be some useful behavior and not a series of no-ops. extensibility - A framework can be extended by the user usually by selective overriding or specialized by user code providing specific functionality. non-modifiable framework code - The framework code, in general, is not allowed to be modified. Users can extend the framework, but not modify its code.

您可能“需要”它，因为它在开发应用程序时为您提供了一个很好的快捷方式，因为它包含了许多已经编写和测试过的功能。原因与我们使用软件库的原因非常相似。
