a simple http server using inner http module.
var http = require('http');
var fs = require('fs');
// 这是一个很有趣的包
require('colors');
var server = http.createServer(function(req, res) {
if ('GET' == req.method && '/images' == req.url.substr(0, 7) && '.jpg' == req.url.substr(-4)) {
console.log(req.url.red);
console.log((__dirname + req.url).red);
fs.stat(__dirname + req.url, function(err, stat) {
if (err || ! stat.isFile()) {
res.writeHead(404);
res.end('Not found');
return;
}
serve(__dirname + req.url, 'image/jpg');
});
} else if ('GET' == req.method && '/' == req.url) {
serve(__dirname + '/index.html', 'text/html');
} else {
res.writeHead(404);
res.end('Not found');
}
function serve(path, type) {
console.log(path.yellow);
console.log(type.red);
res.writeHead(200, {'Content-Type': type});
// 这个是亮点，流的管道方法，类似C++的 <<
fs.createReadStream(path).pipe(res);
}
}).listen(3000);
