Question

我有一个非常基本的风帆应用并在本地运行。当我部署到Heroku时，我无法从应用程序获得响应，然后最终得到“应用程序错误”。我有时会收到“没有收到数据”。

Procfile ：

web: npm start

package.json / scripts ：

  "scripts": {
    "debug": "node debug app.js",
    "start": "sails lift --prod"
  }

配置/ ENV /生产：

module.exports = {

  models: {
    connection: 'mongoDbProd'
  },

  port: 80,

  log: {
     level: "silent"
  }

};

感谢任何方向！

Answer 1

您还可以为Heroku使用专门的buildpack，在部署时运行Grunt任务，然后在生产环境中关闭Sails中的Grunt。这需要更多的工作，但它可能变得必要，因为Heroku有自己的超时，可能会被Grunt绊倒太长时间来破坏你的资产。

我们在heroku-buildpack-nodejs-grunt取得了成功。您可以按照说明在Heroku应用上安装它，然后将tasks/register/prod.js中的任务定义复制到包含heroku:production任务，例如：

module.exports = function (grunt) {

  grunt.registerTask('prod', [
    'compileAssets',
    'concat',
    'uglify',
    'cssmin',
    'sails-linker:prodJs',
    'sails-linker:prodStyles',
    'sails-linker:devTpl',
    'sails-linker:prodJsJade',
    'sails-linker:prodStylesJade',
    'sails-linker:devTplJade'
  ]);

  grunt.registerTask('heroku:production', [
    'compileAssets',
    'concat',
    'uglify',
    'cssmin',
    'sails-linker:prodJs',
    'sails-linker:prodStyles',
    'sails-linker:devTpl',
    'sails-linker:prodJsJade',
    'sails-linker:prodStylesJade',
    'sails-linker:devTplJade'
  ]);

};

最后在您的app.js文件中，替换

sails.lift(rc('sails'));

使用：

var config = rc('sails');
if (process.env.NODE_ENV === 'production') {
  config.hooks = config.hooks || {};
  config.hooks.grunt = false;
}
// Start server
sails.lift(config);

使用以下内容创建文件config / locals.js解决了我的问题：

module.exports = {
   hookTimeout: 30000, // 30 seconds
}

Answer 3

除了设置hookTimeout外，请确保

  migrate: 'alter'

在config / models.js中设置

Answer 4

添加官方Heroku Node.js buildpack为我工作：https://github.com/heroku/heroku-buildpack-nodejs

在Heroku CLI中：

heroku buildpacks:add https://github.com/heroku/heroku-buildpack-nodejs.git

然后：

git push heroku master

一切都应该成功构建，你的应用程序应该在Heroku中正常运行。
