golang: 1.5.1
dlang(ldc2): 2.066.1
nodejs: 4.2.2
php: 4.6.14
golang代码：
package main
import (
"io"
"net/http"
"log"
)
func HelloServer(w http.ResponseWriter, req *http.Request) {
io.WriteString(w, "hello, world!\n")
}
func main() {
http.HandleFunc("/hello", HelloServer)
err := http.ListenAndServe(":1234", nil)
if err != nil {
log.Fatal("ListenAndServe: ", err)
}
}dlang代码：
import std.stdio;
import kerisy.http.server;
import kerisy.utils;
import kerisy.net;
int main (string[] args)
{
Address address = Address("0.0.0.0", 9999);
HTTPServer server = new HTTPServer;
server.listen(address);
return 0;
}nodejs代码：
var http = require('http');
var url = require('url');
http.createServer(function (req, res) {
var path = url.parse(req.url).pathname;
var dt=new Date();
res.writeHead(200, {'Content-Type': 'text/plain'});
res.write("Hello,World ! \n"+dt.getTime());
res.end();}).listen(8888, "127.0.0.1");php代码：
#! /usr/bin/env php
handleConsole(
new Symfony\Component\Console\Input\ArgvInput,
new Symfony\Component\Console\Output\ConsoleOutput
);
exit($status);运行结果如下：
