1 minute to teach you how to reverse proxy OpenAI server!

In Node.js, you can use the http-proxy-middleware library to easily build a reverse proxy server.

Here is a simple example:

First, make sure you have Node.js installed.

Run the following command in the project directory to initialize a new Node.js project:

 npm init -y

Next, install http-proxy-middleware and express:

npm install http-proxy-middleware express

Create a file called proxy.js in the project directory and add the following code to it:

const express = require('express');
const { createProxyMiddleware } = require('http-proxy-middleware');
 
const app = express();
 
// 反向代理配置
const proxyOptions = {
  target: 'https://target-server.com', // 这里是您想要代理的目标服务器地址
  changeOrigin: true, // 修改请求头以适应目标服务器
};
 
// 设置代理
app.use('/api', createProxyMiddleware(proxyOptions));
 
// 启动服务器
const PORT = process.env.PORT || 3000;
app.listen(PORT, () => {
  console.log(`Server is running on port ${PORT}`);
});

In this example, we set up a reverse proxy to proxy all requests starting with /api to https://target-server.com. You can modify the proxy configuration as needed.

Finally, start the proxy server by running the following command:

node proxy.js

You have now successfully created a simple reverse proxy server that proxies requests from your server to the target server. You can further configure and customize the proxy server according to your needs.

If you want to set up a reverse proxy in the China region to access OpenAI's server, please change the target field in the above example to the URL of the OpenAI server. OpenAI's API server address is: https://api.openai.com

Therefore, the reverse proxy configuration in the proxy.js file should be changed to:

const proxyOptions = {
  target: 'https://api.openai.com', // OpenAI API 服务器地址
  changeOrigin: true, // 修改请求头以适应目标服务器
};

Also, make sure your proxy server has internet access and your firewall allows traffic. If your server is located in mainland China, you may need to ensure that you have resolved network access restrictions in order to access international servers.
