Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

node的http请求库的代理工具,支持http、https; 一个即用型 http 和 https 代理,用于使用代理,使连接保持活动状态!

具有以下特性:

  • http
  • https
  • TypeScript 编写
  • 现代化构建工程

如果您在使用的过程中遇到了问题,或者有好的建议和想法,您都可以通过以下方式联系我,期待与您的交流:

3. 安装方式

目前,安装方式有以下几种:

通过 npm (或 yarn、pnpm 等包管理器)安装

npm install agent-proxy

4. 教程

参考下单,根据你的代理服务器 和 后端服务来决定是使用 HttpProxyAgentHttpsProxyAgent

| 代理类 | 代理服务器 | 服务器 | |-------------------|--------|--------| | HttpProxyAgent | HTTP | HTTP | | HttpProxyAgent | HTTPS | HTTP | | HttpsProxyAgent | HTTP | HTTPS | | HttpsProxyAgent | HTTPS | HTTPS |

import { HttpProxyAgent,HttpsProxyAgent } from 'agent-proxy'

选择适合您的使用案例的代理后,您可以对其进行实例化。它与 Node.js 自带的的 http(s) agent 的参数相同,和一个附加选项,即代理的 url

import http from 'node:http'
import { HttpProxyAgent } from 'agent-proxy'

const agent = new HttpProxyAgent({
  keepAlive: true,
  keepAliveMsecs: 1000,
  maxSockets: 256,
  maxFreeSockets: 256,
  proxy: 'http://localhost:8080'
})

http.get('http://localhost:9200', { agent })
    .on('response', console.log)
    .end()

如果您的代理需要基本身份验证,您可以在 proxy url 中对其进行配置:

import http from 'node:http'
import { HttpProxyAgent } from 'agent-proxy'

const agent = new HttpProxyAgent({
  keepAlive: true,
  keepAliveMsecs: 1000,
  maxSockets: 256,
  maxFreeSockets: 256,
  proxy: 'http://user:pwd@localhost:8080'
})

http.get('http://localhost:9200', { agent })
    .on('response', console.log)
    .end()

你也可以通过 'proxyConnectOptions' 选项传递仅用于代理 CONNECT 请求的自定义选项。 例如 headerstls.connect() 选项:

import fs from 'node:fs'
import http from 'node:http'
import { HttpProxyAgent } from 'agent-proxy'

const agent = new HttpProxyAgent({
  keepAlive: true,
  keepAliveMsecs: 1000,
  maxSockets: 256,
  maxFreeSockets: 256,
  proxy: 'https://localhost:8080',
  proxyConnectOptions: {
    headers: {
      'Proxy-Authorization': 'Basic YWxhZGRpbjpvcGVuc2VzYW1l',
    },
    ca: [ fs.readFileSync('custom-proxy-cert.pem') ]
  }
})

http.get('http://localhost:9200', { agent })
    .on('response', console.log)
    .end()

如果你需要创建 HttpProxyAgent 和 HttpsProxyAgent 的实例,并且需要同步管理它们,那你可以使用createProxyAgents() 方法来创建代理

import fs from 'node:fs'
import http from 'node:http'
import { createProxyAgents } from 'agent-proxy'

const {agent,setProxy} = createProxyAgents();

setProxy(proxyUrl);

常用的http请求库集成示例

got

got('http://localhost:9200', {
  agent: {
    http: new HttpProxyAgent({
      keepAlive: true,
      keepAliveMsecs: 1000,
      maxSockets: 256,
      maxFreeSockets: 256,
      scheduling: 'lifo',
      proxy: 'http://localhost:8080'
    })
  }
})

needle

needle('get', 'http://localhost:9200', {
  agent: new HttpProxyAgent({
    keepAlive: true,
    keepAliveMsecs: 1000,
    maxSockets: 256,
    maxFreeSockets: 256,
    scheduling: 'lifo',
    proxy: 'http://localhost:8080'
  })
})

node-fetch

fetch('http://localhost:9200', {
  agent: new HttpProxyAgent({
    keepAlive: true,
    keepAliveMsecs: 1000,
    maxSockets: 256,
    maxFreeSockets: 256,
    scheduling: 'lifo',
    proxy: 'http://localhost:8080'
  })
})

simple-get

sget.concat({
  url: `http://${server.address().address}:${server.address().port}`,
  agent: new HttpProxyAgent({
    keepAlive: true,
    keepAliveMsecs: 1000,
    maxSockets: 256,
    maxFreeSockets: 256,
    scheduling: 'lifo',
    proxy: `https://${proxy.address().address}:${proxy.address().port}`
  })
}, function (err, response, data) {
  // handle the response
})
