用Meteor.js检测环境？ [英] Detecting environment with Meteor.js?

问题描述

任何人都可以使用Meteor.js找出语法或模式来检测托管环境？我有Heroku的buildpacks工作，并有一个开发/生产环境，但我有点绘制一个空白如何让我的应用程序检测到它正在运行的环境。

有没有办法让node.js检测它运行的端口？我希望可能有一些像app.address（）。端口的低级别的东西，但似乎不起作用。

编辑：这是解决方案为我工作。请注意，以下需要在服务器上运行，因此需要包含在server\server.js或类似的文件中。

  if（Meteor.is_server）{
 Meteor.startup（function（）{
 //我们想要检查root_url，所以我们知道我们在
 console.log（JSON.stringify（process.env.ROOT_URL））; 
 
 //如果我们要检查其他进程环境变量
 //console.log(JSON.stringify(process.env））; 
}）; 
} 
  

还创建了以下内容：

  Meteor.methods（{
 getEnvironment：function（）{
 if（process.env.ROOT_URL ==http ：// localhost：3000）{
 returndevelopment; 
} else {
 returnstaging; 
} 
} 
}） ; 
  

其中允许客户端的以下内容：

  Meteor.call（getEnvironment，function（result）{
 console.log（你的应用程序正在运行+结果+environment）; 
}）; 
  

谢谢拉胡尔！

解决方案

您可以检查服务器上的 process.env 变量找到有关当前环境的信息，包括端口：

  {TERM_PROGRAM：'Apple_Terminal'，
 TERM：'xterm -256color'，
 SHELL：'/ bin / bash'，
 TMPDIR：'/ var / folders / y_ / 212wz0cx5vs20yd7y2psnh7m0000gp / T /'，
 Apple_PubSub_Socket_Render：'/ tmp / launch-hch25f / Render'，
 TERM_PROGRAM_VERSION：'309'，
 OLDPWD：'/ usr / local / meteor / bin'，
 TERM_SESSION_ID：'3FE307A0-B8FC-41AD-B1EB-FCFA0B8B25D1'，
 USER：'Rahul'，
 COMMAND_MODE：'unix2003'，
 SSH_AUTH_SOCK：'/ tmp / launch-gFCBXS / Listeners'，
 __CF_USER_TEXT_ENCODING：'0x1F6：0：0' 
 Apple_Ubiquity_Message：'/ tmp / launch-QAWKHL / Apple_Ubiquity_Message'，
 PATH：'/ usr / bin：/ bin：/ usr / sbin：/ sbin：/ usr / local / bin' $ b PWD：'/ Users / Rahul / Documents / Sites / test'，
 NODE_PATH： '/ usr / local / meteor / lib / node_modules'，
 SHLVL：'1'，
 HOME：'/ Users / Rahul'，
 LOGNAME：'Rahul'，
 LC_CTYPE：'UTF-8'，
 SECURITYSESSIONID：'186a4'，
 PORT：'3001'，
 MONGO_URL：'mongodb：//127.0.0.1：3002 / meteor'，
 ROOT_URL：'http：// localhost：3000'} 
  

Anybody figure out syntax or a pattern yet for detecting hosting environment using Meteor.js? I've got Heroku buildpacks working, and have a dev/production environment, but I'm kind of drawing a blank on how to have my app detect which environment it's running in.

Is there a way to have node.js detect which port it's running on? I was hoping there might be something low-level like app.address().port, but that doesn't seem to work...

Edit: This is the solution that worked for me. Note that the following needs to be run on the server, so it needs to be included in server\server.js, or a similar file.

if (Meteor.is_server) {
    Meteor.startup(function () {
        // we want to be able to inspect the root_url, so we know which environment we're in
        console.log(JSON.stringify(process.env.ROOT_URL));

        // in case we want to inspect other process environment variables
        //console.log(JSON.stringify(process.env));
    });
}

Also created the following:

Meteor.methods({
  getEnvironment: function(){
    if(process.env.ROOT_URL == "http://localhost:3000"){
        return "development";
    }else{
        return "staging";
    }
  }
 });    

Which allows for the following on client side:

 Meteor.call("getEnvironment", function (result) {
      console.log("Your application is running in the " + result + "environment.");
 });

Thanks Rahul!

解决方案

You can inspect the process.env variable on the server to find information about the current environment, including the port:

{ TERM_PROGRAM: 'Apple_Terminal',
  TERM: 'xterm-256color',
  SHELL: '/bin/bash',
  TMPDIR: '/var/folders/y_/212wz0cx5vs20yd7y2psnh7m0000gp/T/',
  Apple_PubSub_Socket_Render: '/tmp/launch-hch25f/Render',
  TERM_PROGRAM_VERSION: '309',
  OLDPWD: '/usr/local/meteor/bin',
  TERM_SESSION_ID: '3FE307A0-B8FC-41AD-B1EB-FCFA0B8B25D1',
  USER: 'Rahul',
  COMMAND_MODE: 'unix2003',
  SSH_AUTH_SOCK: '/tmp/launch-gFCBXS/Listeners',
  __CF_USER_TEXT_ENCODING: '0x1F6:0:0',
  Apple_Ubiquity_Message: '/tmp/launch-QAWKHL/Apple_Ubiquity_Message',
  PATH: '/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin',
  PWD: '/Users/Rahul/Documents/Sites/test',
  NODE_PATH: '/usr/local/meteor/lib/node_modules',
  SHLVL: '1',
  HOME: '/Users/Rahul',
  LOGNAME: 'Rahul',
  LC_CTYPE: 'UTF-8',
  SECURITYSESSIONID: '186a4',
  PORT: '3001',
  MONGO_URL: 'mongodb://127.0.0.1:3002/meteor',
  ROOT_URL: 'http://localhost:3000' }
