Fast Middleware exposing user-agent for koa.js based on express-useragent
$ npm install koa-useragent
const koa = require('koa');
const app = koa.app();
const { userAgent } = require('koa-useragent');
app.use(userAgent);
app.use(async (ctx, next) {
console.log(require('util').inspect(ctx.userAgent));
});
app.listen(3000);
import Koa, { BaseContext } from 'koa';
import { userAgent, UserAgentContext } from 'koa-useragent';
const app = new Koa();
app.use(userAgent);
app.use<BaseContext, UserAgentContext>((ctx) => {
console.log(require('util').inspect(ctx.userAgent));
});
app.listen(3000);
Module provides details such as the following:
{
"isMobile":false,
"isDesktop":true,
"isBot":false,
.....
"browser":"Chrome",
"version":"17.0.963.79",
"os":"Windows 7",
"platform":"Microsoft Windows",
"source":"Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/535.11 (KHTML, like Gecko) Chrome/17.0.963.79 Safari/535.11"
}
From version 2.1.0 the library has rewritten in typescript. Definitions files distribute with source files.
From version 1.2.0, the library has type typescript definition file. You can install them from npm.
npm install --save-dev @types/koa-useragent

推荐使用ua-parser-js npm i ua-parser-js --save eg: const parser = require(‘ua-parser-js’); let ua = ctx.headers[‘user-agent’]; let ua_parser = new parser(ua); // 自己检查一些不常用的浏览器 if (/99Browser/.test
目录 简介 应用 上下文(Context) 请求(Request) 响应(Response) 使用koa搭建一个简单的项目(下面的文档可以参考一下) koa2从搭建项目到实现API 这里梳理一下koa2项目简单的流程: app.js引入路由route router中绑定controllers中的方法 controllers处理发送的请求并调用modules中的sql方法 modules中引
因为是koa中间件,所以最起码要先搭起一个koa服务。 先来介绍一下log4js 安装log4js模块 npm install log4js --save appenders 说白了就是配置打印输出源 type: "type":"console",即为控制台打印,多数用于开发测试。 "type":"file",表示日志输出为普通文件,在此种配置下日志会输出到目标文件夹的目标文件中,并会随着文件大小
利用user-agent,判断请求是移动端的还是pc端的。 const checkPhone = (ctx) => { let userAgent = ctx.request.header['user-agent'].toLowerCase(); let pat_phone = /ipad|iphone os|midp|rv:1.2.3.4|ucweb|android|window

koa是Express的下一代基于Node.js的web框架,目前有1.x和2.0两个版本。 历史 1. Express Express是第一代最流行的web框架,它对Node.js的http进行了封装,用起来如下: var express = require('express'); var app = express(); app.get('/', function (req, res) {
Koa 是下一代的 Node.js 的 Web 框架。由 Express 团队设计。旨在提供一个更小型、更富有表现力、更可靠的 Web 应用和 API 的开发基础。 Koa可以通过生成器摆脱回调,极大地改进错误处理。Koa核心不绑定任何中间件,但提供了优雅的一组可以快速和愉悦地编写服务器应用的方法。 示例代码: var koa = require('koa');var app = koa();//
Koa - HelloWorld 以上便是全部了,我们重点来看示例,我们只注册一个中间件, Hello Worler Server: <?php $app = new Application(); // ... $app->υse(function(Context $ctx) { $ctx->status = 200; $ctx->body = "<h1>Hello Worl
