node.js - Heroku 部署应用程序错误

标签 node.js heroku

我正在尝试部署我用 Express 和 Node 编写的 API。我尝试通过连接到 Github 和使用 Heroku Toolbelt 来部署它。两种方式都可以在日志中显示应用程序已成功部署，但我转到该页面，它总是 says :

Application Error

An error occurred in the application and your page could not be served. Please try again in a few moments.

If you are the application owner, check your logs for details.

我用web:nodeindex.js创建了一个Procfile

这是我的 package.json 和 index.js 文件中的代码:

package.json:

{
  "name": "timestamp-microservice",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "edward-hong",
  "repository": {
    "type": "git",
    "url": "https://github.com/edward-hong/timestamp-microservice.git"
  },
  "license": "ISC",
  "engines": {
    "node": "4.4.0"
  },
  "scripts": {
    "start": "node index.js"
  },
  "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:

我想知道如何将其成功部署到 Heroku 上？

最佳答案

静态中间件采用两个参数，一个是要服务的目录的根路径的字符串，以及一个选项对象。

例如

serveStatic('public/ftp', {'index': ['default.html', 'default.htm']})

在您的情况下，第二个参数是一个字符串，这是不正确的。
