我用他们的向导创建了一个新的OpenShift节点应用程序，它在应用程序的根目录中创建了一个索引文件。我想将所有内容放在公用文件夹中，然后将此文件夹设置为静态文件夹。
我是Node的新手，无法找到解决方案，在我提交代码时不会破坏我的OpenShift服务器。我认为这在节点中非常简单。
更新：
节点使用Express，所以我读过我可以使用此代码设置静态文件夹：
app.use(express.static(__dirname + '/public'));
但是添加它会破坏我的服务器（再次）。我在OpenShift上运行它时得到503。
这是我的server.js代码：
#!/bin/env node
// OpenShift sample Node application
var fs = require('fs');
var express = require('express');
var path = require('path');
var favicon = require('serve-favicon');
var logger = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
var routes = require('./routes/index');
var users = require('./routes/users');

if (typeof self.ipaddress === "undefined") {
// Log errors on OpenShift but continue w/ 127.0.0.1 - this
// allows us to run/test the app locally.

我以为我会为那些不了解Node的人解答这个问题：
我使用OpenShift在您创建新节点应用程序时提供的标准样板代码来使用它。要将所有内容移动到公用文件夹并从中提供文件，您只需要在server.js中编辑以下代码：
self.populateCache = function() {
if (typeof self.zcache === "undefined") {
self.zcache = { 'index.html': '' };
}
// Local cache for static content.
self.zcache['index.html'] = fs.readFileSync('./public/index.html'); // < ---- THIS WAS EDITED TO INCLUDE /public
};
然后稍后：
self.initializeServer = function() {
self.createRoutes();
self.app = express.createServer();
self.app.use(express.static(__dirname + '/public')); // < ---- THIS WAS ADDED
// Add handlers for the app (from the routes).
for (var r in self.routes) {
self.app.get(r, self.routes[r]);
}
};
希望以后可以帮助别人。

您可以使用Exprees和Path模块来包含静态文件，例如：
app.use(express.static(path.join(__dirname, 'public')));
