Question

我一直收到这个错误：

我在heroku中查了一下，然后......这表明我的应用程序崩溃了..（感谢heroku ......）。

这是我的package.json：

  {
  "name": "angular-express-part1",
  "version": "0.0.1",
  "private": true,
  "scripts": {
    "start": "NODE_ENV=production nodemon ./bin/www",
    "test": "NODE_ENV=development nodemon ./bin/www"
  },
  "dependencies": {
    "async": "^2.0.0-rc.3",
    "aws-sdk": "^2.3.11",
    "bcryptjs": "^2.3.0",
    "body-parser": "~1.0.0",
    "cli-color": "^0.3.2",
    "cookie-parser": "~1.0.1",
    "crypto": "0.0.3",
    "debug": "~0.7.4",
    "express": "~4.0.0",
    "express-method-override": "0.0.3",
    "jwt-simple": "^0.5.0",
    "moment": "^2.13.0",
    "mongoose": "^4.4.14",
    "morgan": "~1.0.0",
    "request": "^2.72.0",
    "static-favicon": "~1.0.0",
    "underscore": "^1.6.0"
  },
  "engines": {
    "node": "~5.10.0",
    "npm" : "~3.8.0"
  }
}

我的数据库配置：

var mongoose = require('mongoose');

// Connections
var developmentDb = process.env.MONGODB_URI;
var productionDb = process.env.MONGODB_URI;
var usedDb;

// If we're in develoment...
if (process.env.NODE_ENV === 'development') {
    // set our database to the development one
    usedDb = developmentDb;
    // connect to it via mongoose
    mongoose.connect(usedDb);
}

// If we're in production...
if (process.env.NODE_ENV === 'production') {
    // set our database to the development one
    usedDb = productionDb;
    // connect to it via mongoose
    mongoose.connect(usedDb);
}

// get an instance of our connection to our database
var db = mongoose.connection;

// Logs that the connection has successfully been opened
db.on('error', console.error.bind(console, 'connection error:'));
// Open the connection
db.once('open', function callback () {
  console.log('Databsae Connection Successfully Opened at ' + usedDb);
});

不确定是什么。它在生产中工作......

任何清晰度都会非常感激。

回答，因为我还不能发表评论。

如错误所示，路由器在尝试向您的应用程序发送请求时遇到崩溃的进程。在这种情况下，最好运行日志的尾部（例如heroku logs --tail），然后重新启动应用程序并观察堆栈跟踪。在这里，您可以找到有关导致应用崩溃的原因的更多信息。

如果它通过启动，您可能需要进行一些验收测试，以查看您可以遇到什么障碍以使应用程序崩溃，然后在您的日志中抛出异常。
