我正在尝试部署我用Express和Node编写的API。我已尝试通过连接到Github和使用Heroku Toolbelt来部署它。按照日志中的说法，应用程序已成功部署，但我转到页面并始终says：
应用程序错误
应用程序中发生错误，无法提供您的页面。请稍后再试。
如果您是应用程序所有者，请查看日志以获取详细信息。
我用web: node index.js
以下是package.json和index.js个文件中的代码：
package.json：
{
"name": "timestamp-microservice",
"version": "1.0.0",

},
"dependencies": {
"body-parser": "^1.15.1",
"express": "^4.13.4",
"moment": "^2.13.0"
}
}
index.js：
var express = require('express');
var bodyParser = require('body-parser');
var moment = require('moment');
var port = process.env.PORT || 3000;
var app = express();
var timeRouter = express.Router();
timeRouter.use(bodyParser.json());
timeRouter.route('/:time')
.get(function(req, res, next){
var time = req.params.time;
var unixTime = Number(time);
if (unixTime){
res.json({'unix': unixTime, 'natural': moment.unix(unixTime).format('MMMM D, YYYY')});
} else {
if (moment(time).isValid()){
res.json({'unix': Number(moment(time).format('X')), 'natural': moment(time).format('MMMM D, YYYY')});
} else {
res.json({'unix': null, 'natural': null});
}
}
});
app.use('/', timeRouter);
app.use(express.static(__dirname, 'index.html'));
app.listen(port, function(){
console.log('Server running at http://oursite:' + port);
});
以下是日志：

我想知道如何将它成功部署到Heroku上？
答案 0 :(得分：2)
静态中间件有两个参数，一个字符串，它是要服务的目录的根路径，以及一个选项对象。
例如
serveStatic('public/ftp', {'index': ['default.html', 'default.htm']})
在你的情况下，第二个参数是一个字符串，这是不正确的。
