1. Purchase a Domain

• Purpose: You need a domain name to host your proxy service.
• Recommended: Choose a cheap domain extension like .xyz, .ga, or .cf.

2. Register Cloudflare Account

• Sign Up: Go to Cloudflare’s official website and create an account.
• Login: Log in to your Cloudflare dashboard.

3.Add-site to Cloudflare

• Step 1: Click Add Site > Add a Site.
• Step 2: Enter your domain name (e.g., yourdomain.com) and click Next.
• Step 3: Cloudflare will scan your domain’s current DNS records. Click Continue Setup.
• Step 4: Choose Free Plan (the basic plan is sufficient for a proxy service).
• Step 5: Update DNS Nameservers:
  • Your domain registrar (e.g., Alibaba Cloud) requires updating nameservers to Cloudflare’s:
    • Nameserver 1: ns1.cloudflare.com
    • Nameserver 2: ns2.cloudflare.com
  • Follow your domain registrar’s instructions to update nameservers. This step ensures Cloudflare manages your DNS.

4.Configure DNS Records

• Proxy Settings:Go to the DNS tab in Cloudflare.
• Add a New A Record:
  • Click Add Record > select A record.
  • Fill in the fields:
    • Name: Enter pixiv (or a custom subdomain name, e.g., proxy).
    • IPv4 Address: Enter any valid IP address (e.g., 8.8.8.8 for testing purposes).
    • TTL: Keep it as Auto (recommended).
• Enable Proxy Status:
  • Check the box Proxy this record (the icon will turn orange).
  • This enables Cloudflare’s proxy for this subdomain.
• Save Changes:
  • Click Save to apply the configuration.

5. Set Up Cloudflare Workers

1. Go to Workers > Create a Worker.
2. Create a New Service:
   • Click Create a Worker.
   • Name: Enter a name (e.g., pixiv-proxy).
   • Route: Set the route to https://pixiv.yourdomain.com/* (replace yourdomain.com with your domain).
   • Click Create Service.
3. Edit the Worker Code:
   • Go to the Resources tab.
   • Click Quick Edit to open the code editor.
   • Replace the default code with the following script (explained below):

addEventListener('fetch', event => {
    let url = new URL(event.request.url);
    url.hostname = 'i.pximg.net';   
    let request = new Request(url, event.request);
    event.respondWith(
        fetch(request, {
            headers:{
                'Referer': 'https://www.pixiv.net', //Websites that require proxy access
                'User-Agent':'Cloudflare Workers'   //Proxy server
            }
        })
    );
});

6.Bind the Custom Domain

1. Return to the Dashboard:
   • Go back to the Cloudflare dashboard homepage.
