create a http server with a connect route in go

To create an HTTP server with a connect route in Go, you can use the standard http package along with the net/http package.


main.go
package main

import (
    "fmt"
    "net/http"
)

func main() {
    // create a new mux (http router) instance
    mux := http.NewServeMux()

    // create a handler function for the connect route
    handleConnect := func(w http.ResponseWriter, r *http.Request) {
        fmt.Fprintf(w, "Hello, this is a CONNECT request!")
    }

    // register the connect handler with the mux
    mux.HandleFunc("/", handleConnect)

    // create a new http server instance
    server := &http.Server{
        Addr:    ":8080",
        Handler: mux,
    }

    // start the http server
    fmt.Printf("Starting server on port %s\n", server.Addr)
    if err := server.ListenAndServe(); err != nil {
        panic(err)
    }
}

In this example, we first create a mux instance, which acts as our HTTP router. We then define a handler function for the CONNECT verb using http.HandleFunc which just responds with a "Hello, this is a CONNECT request!" message. Finally, we create a new http.Server instance using our mux, and call ListenAndServe() on it to start the server. The server listens on port 8080 in this example.

To test this server, you can use a tool like curl to make a CONNECT request to localhost:8080. For example:


main.go
$ curl -X CONNECT localhost:8080
Hello, this is a CONNECT request!

This should output the "Hello, this is a CONNECT request!" message we defined in our handler function.
