Task.StartNew() vs Parallel.ForEach : Multiple Web Requests Scenario

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效,请关闭广告屏蔽插件后再试): 问题: I have read through all the related questions in SO, but a little confused on the best approach for my scenario where multiple web service calls are fired. I have an aggregator service that takes an input, parses and translates it into multiple web requests, makes the web request calls (unrelated, so could be fired in parallel) and consolidates the response which is sent back to the caller. The following code is used right now - list.ForEach((object obj) => { tasks.Add(Task.Factory.StartNew((object state) => { this.ProcessRequest(obj); },

async await 的原理

在公司的项目中,我们经常用到async await 这样的函数,它的作用也很奇特,可以让异步的函数等待异步执行的结果出来再继续往下进行。我一直很好奇这是怎么做到的,它内部的机理是怎么样的,就一个关键词在函数前面加async,在异步操作前面加await就可以做到。他是怎么做到的呢? 现在我们用的vue项目就会把我们的语法打包编辑成浏览器可以识别的语句,那么async,await 是从什么地方出来的呢,他是怎么实现异步变同步的呢? 我们的异步操作async await 如果错了就不会继续执行,如果我想让他继续执行应该怎么做? try cache? 还有呢? 为什么可以呢?内部是怎么执行的呢? function Fun () { return new Promise((resolve,reject) => { setTimeout(reject( new Error ( '你错了' )), 3000 ); }) } function Fun2 () { return new Promise((resolve) => { setTimeout(resolve, 3000 ); }) } async function g () { // try{ await Fun(); // }catch(e){ // console.log('错了'); // } console.log( 123 );
