Integrating Siyuan VPN with Cloudflare Workers

In this article, we will explore how to integrate Siyuan VPN with Cloudflare Workers to build a secure communication channel with the Cloudflare global network. By doing so, you can ensure that your traffic is encrypted and secure, and your online activities are protected.

Step 1: Setting up Siyuan VPN

Before we start, we need to set up Siyuan VPN. You can download the Siyuan VPN client from the official website, and follow the instructions to install it on your device.

Once you have installed Siyuan VPN, you need to connect to a Siyuan VPN server to establish a secure connection. You can choose a server location based on your preferences.

Step 2: Creating a Cloudflare Workers script

To create a Cloudflare Workers script, you will need a Cloudflare account. If you don't have one, you can sign up for a free account at the Cloudflare website.

After you have signed up for a Cloudflare account, you can create a new Workers script by navigating to the Workers dashboard and clicking "Create a Worker". You can then paste the following code into the editor:

addEventListener('fetch', event => {
  event.respondWith(handleRequest(event.request))
})

async function handleRequest(request) {
  const url = new URL(request.url)
  const cf = request.headers.get('cf-connecting-ip')
  const clientIP = cf || request.headers.get('x-real-ip') || request.headers.get('x-forwarded-for') || request.headers.get('remote_addr')

  const upstreamURL = url.toString().replace(url.origin, 'https://www.example.com')
  const upstreamRequest = new Request(upstreamURL, request)

  upstreamRequest.headers.delete('Host')
  upstreamRequest.headers.set('Host', new URL(upstreamURL).hostname)

  return await fetch(upstreamRequest)
}

Step 3: Adding Siyuan VPN to the Cloudflare Workers script

Now that you have created a basic Cloudflare Workers script, you need to add Siyuan VPN to it. To do this, you will need to add the following code at the beginning of the script:

const siyuanVPN = new SiyuanVPN();
await siyuanVPN.connect();

This code will initialize the Siyuan VPN client and connect it to the Siyuan VPN server. By doing this, all traffic from the Cloudflare Workers script will be routed through Siyuan VPN, ensuring that it is encrypted and secure.

Step 4: Testing the Siyuan VPN and Cloudflare Workers integration

To test the integration between Siyuan VPN and Cloudflare Workers, you can deploy the Workers script to the Cloudflare global network, and then access the script using a web browser. You should see that the IP address that is returned is the IP address of the Siyuan VPN server, rather than your own IP address.

Conclusion

In this article, we have explored how to integrate Siyuan VPN with Cloudflare Workers to build a secure communication channel with the Cloudflare global network. By doing so, you can ensure that your traffic is encrypted and secure, and your online activities are protected. With this integration, you can also bypass censorship and access content that may be restricted in your region.
