create a http server with a patch route in go

Here's an example code for creating a HTTP server in Go with a PATCH route:

main.go
package main

import (
    "fmt"
    "log"
    "net/http"
)

func main() {
    // Define the PATCH route and its handler function
    http.HandleFunc("/my-resource", func(w http.ResponseWriter, r *http.Request) {
        if r.Method == "PATCH" {
            // Your PATCH logic goes here...
            fmt.Fprint(w, "Resource updated successfully!")
        } else {
            http.Error(w, "Method not allowed", http.StatusMethodNotAllowed)
        }
    })

    // Start the HTTP server
    log.Fatal(http.ListenAndServe(":8080", nil))
}

In this code example, we use the http.HandleFunc function to define a route for /my-resource. Inside the handler function, we check the request method and only execute the PATCH logic if the method is indeed PATCH. Otherwise, we return a Method not allowed error with HTTP status code 405.

Note that we use fmt.Fprint to write a simple success message back to the client. In a real-world scenario, you might want to use a more elaborate response.

Finally, we start the HTTP server using http.ListenAndServe and logging any errors that might occur.
