Code Structure Analysis

The main function is to serve as a reverse proxy server, handling HTTP requests, performing the corresponding redirection, dealing with CORS issues, and modifying HTML content, such as links, form actions, and image sources.

Event Listener

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

This part of the code listens to all incoming HTTP requests and passes these requests to the handleRequest function for processing.

HandleRequest Function

async function handleRequest(request) {
  // ...
}

This is an asynchronous function that takes an HTTP request, parses and processes it, and then returns a new HTTP response.

Its main functions include:

• Parsing and redirecting URLs
• Modifying request headers
• Modifying response headers to handle CORS issues
• Modifying HTML content, such as links, form actions, and image sources

Matters Needing Attention

• Ensure that the Cloudflare Worker is correctly configured and can access the Internet.
• Since this is a reverse proxy server, all requests will go through it. Therefore, make sure your Cloudflare plan includes sufficient bandwidth and processing power.
• Ensure server security to prevent malicious use.
