Question

我正在尝试使用molnarg的node-http2模块在节点服务器上实现HTTP / 2。我原来的server.js运行正常，当我实现HTTP / 2模块时，我得到了一个

ERR_CONNECTION_REFUSED

来自浏览器（使用ChromeBook上的Chrome）。

实施HTTP / 2的更改列表：

创建了证书＆amp;关键.perm的
将config.json中的hostPort var更改为443（尝试w / 80,8000）
添加到server.js：

var certs = {key: fs.readFileSync('../../key.pem'),cert: fs.readFileSync('../../cert.pem')};
编辑server.js

require('http').createServer(function (request, response) {...}

到

require('http2').createServer(certs, function (request, response) {...}

我错过了什么或者有什么问题（我在日志中没有错误）？

以下是server.js

var environment = '../env/' + process.env.NODE_ENV;

// Process User config
var fS = require('fs')
  , jsonFile = fS.readFileSync(environment + '/config.json'), jsonString, hostIp, hostPort, cacheExp, cps;

try {
  jsonString              = JSON.parse(jsonFile);
  var SERV_HOST           = jsonString['hostIp']
    , SERV_PORT           = jsonString['hostPort']
    , CACHE_EXP           = jsonString['cacheExp']
    , CPS                 = jsonString['cps']
    , xPowerBy            = ''
    , xFrameOptions       = ''
    , xXSSProtection      = ''
    , xContentTypeOption  = ''
    , cacheControl        = '';
} catch (err) {
  console.log('There is an error parsing the json file : ' + err);
}

// Load required modules
var web       = require('node-static')
  , watch     = require('staticsmith-watch')
  , fs        = require("fs");

var certs = {
  key: fs.readFileSync('key.pem'),
  cert: fs.readFileSync('cert.pem')
};

// Load security setings via config.json
var security  =
    [{
      // Just some security stuff here
    }];

if (process.env.NODE_ENV == 'production') {

  var options = { host:   SERV_HOST
                , port:   SERV_PORT
                , cache:  CACHE_EXP
  };

  var public_dir = new web.Server(environment, options);

  // Serve it up!
  require('http2').createServer(certs, function (request, response) {
  // OLD 
  // require('http').createServer(function (request, response) {

    // Add Content Security Rules
    for(var i = 0; i < security.length; i++){
        response.setHeader(security[i].name, security[i].option);
      }

    request.addListener('end', function () {

        public_dir.serve(request, response, function (err, result) {
            if (err) { // There was an error serving the file
                console.error("Error serving " + request.url + " - " + err.message);
                // Respond to the client
                response.writeHead(err.status, err.headers);
                response.end();
            }
        });
    }).resume();
  }).listen(options.port, options.host);

  console.log("serving at http://" + options.host + ":" + options.port);
  console.log("On Node v" + process.versions.node);

  watch({
    pattern:    '**/*',
    livereload: true,
  });
}

使用node-spdy的实现来代替node-http2，因为这个模块可以在node.js中创建具有自然http模块接口的HTTP2 / SPDY服务器，并且可以回退到常规的https（对于那些不喜欢的浏览器）。 t既不支持HTTP2，也不支持SPDY）。

above server.js正在实施新模块：

var environment = '../env/' + process.env.NODE_ENV;

// Process User config
var fS = require('fs')
  , jsonFile = fS.readFileSync(environment + '/config.json'), jsonString, hostIp, hostPort, cacheExp, cps;

try {
  jsonString              = JSON.parse(jsonFile);
  var SERV_HOST           = jsonString['hostIp']
    , SERV_PORT           = jsonString['hostPort']
    , CACHE_EXP           = jsonString['cacheExp']
    , CPS                 = jsonString['cps']
    , xPowerBy            = ':P'
    , xFrameOptions       = ''
    , xXSSProtection      = ''
    , xContentTypeOption  = ''
    , cacheControl        = '';
} catch (err) {
  console.log('There is an error parsing the json file : ' + err);
}

// Load required modules
var fs    = require('fs')
  , web   = require('node-static');

var public_dir = new web.Server(environment + '/_public');

var options = {
    key: fs.readFileSync(environment + '/keys/key.pem')
  , cert: fs.readFileSync(environment + '/keys/cert.pem')

  // SPDY-specific options 
  , spdy: {
      protocols: [ 'h2','spdy/3.1', 'spdy/3', 'spdy/2','http/1.1', 'http/1.0' ],
      plain: false,

      connection: {
        windowSize: 1024 * 1024, // Server's window size 

        // **optional** if true - server will send 3.1 frames on 3.0 *plain* spdy 
        autoSpdy31: false
      }
    }

  , host:   SERV_HOST
  , port:   SERV_PORT
  , cache:  CACHE_EXP

};

// Load security setings via config.json
var security  = [
    { name:   'X-Powered-By',
      option: xPowerBy }
  , { name:   'x-frame-options',
      option: xFrameOptions }
  , { name:   'X-XSS-Protection',
      option: xXSSProtection }
  , { name:   'X-Content-Type-Options',
      option: xContentTypeOption }
  , { name:   'Cache-Control',
      option: CACHE_EXP }
  , { name:   'Content-Security-Policy',
      option: CPS }
  , { name:   'server',
      option: 'Who knows' }
];

if (process.env.NODE_ENV == 'production') {

  require("spdy").createServer(options, function(req, res) {

    // Add Content Security Rules
    for(var i = 0; i < security.length; i++){
      res.setHeader(security[i].name, security[i].option);
    }

    public_dir.serve(req, res, function (err, result) {
      if (err) { // There was an error serving the file
        console.error("Error serving " + req.url + " - " + err.message);
        // Respond to the client
        res.writeHead(err.status, err.headers);
        res.end();
      }
    });
  }).listen(options.port, options.host);
  console.log("serving at https://" + options.host + ":" + options.port);
  console.log("On Node v" + process.versions.node);
}

这开箱即用。
