Too naive HTTP client and server

cohhei/http is a too simple and naive HTTP client and server library that doesn't depend on net/http. This client has only one method, Do which sends an HTTP request.

Usage

HTTP client

package main

import (
	"fmt"
	"io"
	"log"
	"os"

	"github.com/cohhei/http"
)

func main() {
	// Create a client.
	c := http.NewClient()

	// Create a request.
	req := &http.Request{
		Method: "GET",
		Host:   "example.com",
		Path:   "/index.html",
		Header: Header{},
	}

	// Send the request.
	resp, err := c.Do(req)
	if err != nil {
		log.Fatal(err)
	}

	fmt.Println(resp)
	io.Copy(os.Stdout, resp.Body)
}

HTTP server

package main

import (
	"io"
	"log"
	"os"

	"github.com/cohhei/http"
)

func main() {
	log.SetFlags(log.LstdFlags | log.Lshortfile)
	http.HandleFunc("/", func(w io.Writer, r io.Reader) {
		io.Copy(os.Stderr, r)
		w.Write([]byte("HTTP/1.1 200 OK\naaaaa: bbbbbb\n\nHello World!"))
	})
	log.Print("http://127.0.0.1:8080/")
	if err := http.ListenAndServe(8080); err != nil {
		log.Fatal(err)
	}
}

Too naive TCP client

This package has a TCP client that depends on only syscall.

TCP client usage

// Create a client
c := http.NewTCPClient()

// Connect to the address
ip := [4]byte{127, 0, 0, 1}
port := 11111
if err := c.Connect(ip, port); err != nil {
  	log.Fatal(err)
}

// Read data
resp, err := c.Read()
if err != nil {
	log.Fatal(err)
}
io.Copy(os.Stdout, resp)

// Write data
n, err := c.Write([]byte("world"))
if err != nil {
	log.Fatal(err)
}

Too naive UDP client

This package has a UDP client that depends on only syscall.

UDP client usage

c := http.NewUDPClient()
ip := [4]byte{8, 8, 8, 8}
port := 53
b := []byte{0x01}
if err := c.SendTo(b, ip, port); err != nil {
	log.Fatal(err)
}
defer c.Close()

resp, err := c.Recvfrom()
if err != nil {
	log.Fatal(err)
}

io.Copy(os.Stdout, resp)
