centos7 node express項目 將http介面升級為https介面的解決方案

標籤：bin   utf8   parse   join   bubuko   als   服務   listen   pipe   

1、將對應的ssl認證放到專案檔中（我裝的鏡像是oneinstack的，建立項目時可以直接選擇產生ssl認證的項目，即 xxx.key 和 xxx.crt 檔案）；

2、修改bin/www檔案，修改代碼如下：

#!/usr/bin/env node/** * Module dependencies. */var app = require(‘../app‘);var debug = require(‘debug‘)(‘https:server‘);
//關鍵包var path = require(‘path‘); var https = require(‘https‘);var fs = require(‘fs‘);
//ssl認證相關檔案var privateKey  = fs.readFileSync(path.join(__dirname, ‘./https.key‘), ‘utf8‘);var certificate = fs.readFileSync(path.join(__dirname, ‘./https.crt‘), ‘utf8‘);var credentials = {key: privateKey, cert: certificate};/** * Get port from environment and store in Express. */var port = normalizePort(process.env.PORT || ‘8081‘); //連接埠號碼app.set(‘port‘, port);/** * Create HTTP server. */var server = https.createServer(credentials, app); //新的https服務/** * Listen on provided port, on all network interfaces. */server.listen(port);server.on(‘error‘, onError);server.on(‘listening‘, onListening);/** * Normalize a port into a number, string, or false. */function normalizePort(val) {  var port = parseInt(val, 10);  if (isNaN(port)) {    // named pipe    return val;  }  if (port >= 0) {    // port number    return port;  }  return false;}/** * Event listener for HTTP server "error" event. */function onError(error) {  if (error.syscall !== ‘listen‘) {    throw error;  }  var bind = typeof port === ‘string‘    ? ‘Pipe ‘ + port    : ‘Port ‘ + port;  // handle specific listen errors with friendly messages  switch (error.code) {    case ‘EACCES‘:      console.error(bind + ‘ requires elevated privileges‘);      process.exit(1);      break;    case ‘EADDRINUSE‘:      console.error(bind + ‘ is already in use‘);      process.exit(1);      break;    default:      throw error;  }}/** * Event listener for HTTP server "listening" event. */function onListening() {  var addr = server.address();  var bind = typeof addr === ‘string‘    ? ‘pipe ‘ + addr    : ‘port ‘ + addr.port;  debug(‘Listening on ‘ + bind);}

3、項目重啟，輸入https://localhost:8081，能看到網頁如下顯示，則代表https服務成功。

註：雖然已經是https服務了，但還是會報不安全提示，是因為我們的認證問題。不影響正常功能。
