什么错误在NodeJS

What the error in NodeJS

本文关键字：NodeJS 错误 什么      更新时间：2023-09-26

我的应用程序在NodeJS 0.10运行在我的节点localhost(127.0.0.1)和我的链接不听，和发现OpenShift !但没有运行我的脚本，错误:(http://nodejs2-agenciadreamup.rhcloud.com/)，我的GitHub (https://github.com/AlanPS/StreamBrasil)…帮助我!!

我代码:

var http = require('http'),
  fs = require('fs'),
  util = require('util');
http.createServer(function (req, res) {
  var path = __dirname + '/aula.mp4';
  var stat = fs.statSync(path);
  var total = stat.size;
  if (req.headers['range']) {
    var range = req.headers.range;
    var parts = range.replace(/bytes=/, "").split("-");
    var partialstart = parts[0];
    var partialend = parts[1];
    var start = parseInt(partialstart, 10);
    var end = partialend ? parseInt(partialend, 10) : total-1;
    var chunksize = (end-start)+1;
    console.log('RANGE: ' + start + ' - ' + end + ' = ' + chunksize);
    var file = fs.createReadStream(path, {start: start, end: end});
    res.writeHead(206, { 'Content-Range': 'bytes ' + start + '-' + end + '/' + total, 'Accept-Ranges': 'bytes', 'Content-Length': chunksize, 'Content-Type': 'video/mp4' });
    file.pipe(res);
  } else {
    console.log('ALL: ' + total);
    res.writeHead(200, { 'Content-Length': total, 'Content-Type': 'video/mp4' });
    fs.createReadStream(path).pipe(res);
  }
}).listen(8080, "127.0.0.1");
console.log('Server running at 127.0.0.1:8080');

看起来服务器正在使用127.0.0.1:8080，而不是openshift的情况。修改如下:

var http = require('http'),
  fs = require('fs'),
  util = require('util');
// if on OpenShift, use OpenShift ip/port, else use your local ip/port
var ipAddress = process.env.OPENSHIFT_INTERNAL_IP || process.env.OPENSHIFT_NODEJS_IP || "127.0.0.1";
var port = process.env.OPENSHIFT_INTERNAL_IP || process.env.OPENSHIFT_NODEJS_PORT || 8080;
http.createServer(function (req, res) {
  // This part of code is unchanged, so it's removed to simplify
  // the answer
}).listen(port, ipAddress);  // <<<<< use variables set above
console.log('Server running at ' + ipAddress + ":" + port);

为了将服务器连接到OpenShift的路由系统，您需要包含对系统提供的虚拟IP地址(process.env.OPENSHIFT_NODEJS_IP)的检查。

如果你的应用程序失败，或者无法建立连接，路由系统会响应503。
