如何使用express over cloudfoundry提供静态文件？我试图使用以下代码：

app.use(express.static(__dirname+'/www'));

但是当我访问特定网址时，我得到了一些奇怪的例外：

Answer 1

我也犯了这个错误，我找到了答案; 你可以这样做：

第一 vmc delete yourapp

第二vmc push yourapp --runtime node08

也许您在第一次将应用程序推送到云时选择了Node运行时（node04，node06）的错误代码，并且服务器会记住您的选择。

这应该有效，如果您创建模板快速应用程序，它将配置为从./public文件夹提供静态资产。确保您的配置是这样的;

var app = express();

app.configure(function(){
  app.set('port', process.env.VCAP_APP_PORT || 3000);
  app.set('views', __dirname + '/views');
  app.set('view engine', 'jade');
  app.use(express.favicon());
  app.use(express.logger('dev'));
  app.use(express.bodyParser());
  app.use(express.methodOverride());
  app.use(app.router);
  app.use(express.static(__dirname + '/public'));
});

如果您愿意，我可以尝试自行部署您的资源，看看我是否可以让它工作。
