直接上代码吧,我把它命名为 app.js, 只要在该文件所在目录下,控制台运行 node app.js 即可启动一个本地服务器了。
/** * 服务器 * Author jervy * Date */ var MINE_TYPES = { ‘html‘: ‘text/html‘, ‘xml‘: ‘text/xml‘, ‘txt‘: ‘text/plain‘, ‘css‘: ‘text/css‘, ‘js‘: ‘text/javascript‘, ‘json‘: ‘application/json‘, ‘pdf‘: ‘application/pdf‘, ‘swf‘: ‘application/x-shockwave-flash‘, ‘svg‘: ‘image/svg+xml‘, ‘tiff‘: ‘image/tiff‘, ‘png‘: ‘image/png‘, ‘gif‘: ‘image/gif‘, ‘ico‘: ‘image/x-icon‘, ‘jpg‘: ‘image/jpeg‘, ‘jpeg‘: ‘image/jpeg‘, ‘wav‘: ‘audio/x-wav‘, ‘wma‘: ‘audio/x-ms-wma‘, ‘wmv‘: ‘video/x-ms-wmv‘, ‘woff2‘: ‘application/font-woff2‘ }; var PORT = 3000; var http = require(‘http‘); var url = require(‘url‘); var fs = require(‘fs‘); var path = require(‘path‘); var root = process.cwd(); var server = http.createServer(function(request, response) { var pathname = decodeURIComponent(url.parse(request.url).pathname); var realPath = path.join(root, pathname); var ext = path.extname(realPath); if (!ext) { realPath = path.join(realPath, ‘/index.html‘); ext = ‘.html‘ } fs.exists(realPath, function(exists) { if (exists) { fs.readFile(realPath, ‘binary‘, function(err, file) { if (!err) { response.writeHead(200, { ‘Content-Type‘: MINE_TYPES[ext.slice(1)] || ‘text/plain‘ }); response.write(file, ‘binary‘); response.end(); } else { response.writeHead(500, { ‘Content-Type‘: ‘text/plain‘ }); response.write(‘ERROR, the reason of error is ‘ + err.code + ‘; Error number is ‘ + err.errno + ‘.‘); response.end(); } }) } else { response.writeHead(404, { ‘Content-Type‘: ‘text/plain‘ }); response.write(‘This request URL ‘ + pathname + ‘ was not found on this server.‘); response.end(); } }); }); server.listen(PORT); console.log("server running at port " + PORT);
