ASP.NET Core Middleware 抽丝剥茧

一. 宏观概念 ASP.NET Core Middleware是在应用程序处理管道pipeline中用于处理请求和操作响应的组件. 每个组件是pipeline 中的一环. 自行决定是否将请求传递给下一个组件 在处理管道的下个组件执行之前和之后执行业务逻辑 二. 特性和行为 ASP.NET Core处理管道由一系列请求委托组成,一环接一环的被调用,pipeline封装了其中的处理环节,下面是更细化的Middleware 处理管道 时序图:   从上图可以看出,请求自进入处理管道,经历了四个中间件,…

跟我一起学.NetCore之中间件(Middleware)简介和解析请求管道构建

前言 中间件(Middleware)对于Asp.NetCore项目来说,不能说重要,而是不能缺少,因为Asp.NetCore的请求管道就是通过一系列的中间件组成的:在服务器接收到请求之后,请求会经过请求管道进行相关的过滤或处理: 正文 那中间件是那路大神? 会经常听说,需要注册一下中间件,如图: 所以说,中间件是针对请求进行某种功能需求封装的组件,而这个组件可以控制是否继续执行下一个中间件:如上图中的app.UserStaticFiles()就是注册静态文件处理的中间件,在请求管道中就会处理对应…

ASP.NET Core 中间件（Middleware)（一）

本文主要目标:记录Middleware的运行原理流程,并绘制流程图. 目录结构: 1.运行环境 2.Demo实践 3.源码追踪 4.AspnetCore内置middleware 一.运行环境 Visual Studio Community 2019 版本 16.8.5 .Net Sdk Version: 5.0.103 二.Demo实践 讲解或学习一个东西的时候,最方便的方式是先写一个Demo.基于此,我写以一个中间件的记录请求输出的实践Demo来理解Middleware. 实体: public…

源码解析.Net中Middleware的实现

前言 本篇继续之前的思路,不注重用法,如果还不知道有哪些用法的小伙伴,可以点击这里,微软文档说的很详细,在阅读本篇文章前,还是希望你对中间件有大致的了解,这样你读起来可能更加能够意会到意思.废话不多说,咱们进入正题(ps:读者要注意关注源码的注释哦). Middleware类之间的关系 下图也是只列出重要的类和方法,其主要就是就ApplicationBuilder类,如下图: 源码解析 1.在使用中间件时,需要在StartUp类的Config方法中来完成(.Net自带的中间件,官方有明确过使用的…
