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 🙏

一个可用于内网穿透的HTTP代理工具

code style: prettier

需要准备的

一台拥有公网IP的服务器 node 8.0+ 一台需要内网穿透的客户端 node 8.0+

Usage

首先在客户端和服务端安装http-proxy2

npm i http-proxy2 -g

在服务端

proxy2 server -p <公网监听端口>
# demo: proxy2 server -p 8123

在客户端

proxy2 client -s <服务端IP> -p <将请求转发到的本地端口>
# demo: proxy2 client -s 139.129.132.196 -p 3000

之后在客户端访问服务端IP:公网监听端口，如: 139.129.132.196:8123，即可发现请求已被转发。

可以在服务端看到输出:

可以在客户端看到输出:

原理

  1. 在服务器上启动一个HTTP服务器，用于接收用户的请求
  2. 服务器和客户端Socket连接。服务器作为Socket的Server端，客户端作为Socekt的Client端
  3. Server端将接收到的HTTP请求进行解析，转发到Client端
  4. Client端解析收到的Socket数据，并将其转发到需要代理的端口
  5. Client向Server端返回数据
  6. Server端的HTTP服务器向用户返回数据

难点

  1. TCP下的黏包、拆包问题
  2. 针对HTTP请求，POST请求，图片请求等解析
  3. Socket编程中一些令人意想不到的坑点
