httpserver

httpserver

This package provides a simple HTTP server that can be used to serve HTTP, HTTPS and FCGI requests. For example:

package main

import (
    "github.com/mutablelogic/go-server/pkg/httpserver"
)

func main() {
    // Create the server
    config := httpserver.Config{}
    server, err := config.New(context.Background())

    // Run the server for five seconds
    ctx, cancel := context.WithTimeout(context.Background(), 5*time.Second)
    defer cancel()
    if err := server.Run(ctx); err != nil {
        log.Fatal(err)
    }
}

Serving HTTP requests

To serve HTTP requests, create a new server with the default configuration. By default, the default router is of type *http.ServeMux. For example, the following creates a server that listens on port 8080:

func main() {
    server, err := httpserver.Config{ Listen: ":8080" }.New(context.Background())
    if err != nil {
        log.Fatal(err)
    }

    // Set the router handers
    server.Router().(*http.ServeMux).HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
        w.Write([]byte("Hello, World!"))
    })

    // ....
}

You can use a random port by setting the listen parameter to : or :0. You can find out which port the server is listening on by calling server.Addr(). The timeout for serving requests can be set using the Timeout parameter.

Serving HTTPS requests

To serve HTTPS requests, create a new server with the default configuration and set the TLS parameter to the path for the key and certificate files. For example,

func main() {
    server, err := httpserver.Config{
        TLS: httpserver.TLSConfig{
            Key: "server.key",
            Cert: "server.crt",
        },
    }.New(context.Background())
    if err != nil {
        log.Fatal(err)
    }

    // ....
}

Serving FCGI requests

To serve requests over FastCGI using a unix socker, create a new server with the path to the socket:

func main() {
    server, err := httpserver.Config{
        Listen: "socket.fcgi",
        Group: "http",
    }.New(context.Background())
    if err != nil {
        log.Fatal(err)
    }

    // ....
}

Set the Owner and Group configuration parameters to the user and group permissions for the socket file.

Using a custom router

To use a custom router, set the Router parameter to the router you want to use. For example, to use the gorilla/mux router:

package main

import (
    httpserver "github.com/mutablelogic/go-server/pkg/httpserver"
    mux "github.com/gorilla/mux"
)

func main() {
    server, err := httpserver.Config{
        Router: mux.NewRouter(),
    }.New(context.Background())
    if err != nil {
        log.Fatal(err)
    }

    // Set the router handers
    server.Router().(*mux.Router).HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
        w.Write([]byte("Hello, World!"))
    })

    // ....
}
