http - 在谈论 HTTP 请求时，Go lang 中的这个 CONTEXT 是什么？

Question

对某些人来说，这可能是一个愚蠢的问题。另一方面，这对我来说非常重要。我是 Go 编程的新手，当我读到这篇文章时 Sharing values between Middlewares还有这个Go Concurrency Patterns: Context当提到在中间件处理程序或请求处理程序之间共享值时，我无法弄清楚 Context 到底是什么意思。

我已经能够使用 Go 编写 Web 框架 -- Frodo .在很多方面并不完美，这是一个学习实验。如你所见，我并不愚蠢。刚接触 Go 语言的消息不多。

提前感谢您的全面解释。

我在这个博客的开头找到了一个很好的解释:HTTP Request Contexts & Go

Request contexts, for those new to the terminology, are typically a way to pass data alongside a HTTP request as it is processed by handlers (or middleware) you have written. This data could be a user ID, a CSRF token, a web token, whether a user is logged in or not—something typically derived from logic that you don't want to repeat over-and-over again in every handler. If you've ever used Django, the request context is synonymous with the request.META dictionary.
