让Heroku的配置变量在node.js中工作

I have a node app that has a line like this:

我有一个节点应用程序有这样的行：

var ip = process.env.IP || 'http://localhost';

I am using it with passport-facebook node package to define the callback from Facebook authentication:

我使用passport-facebook节点包来定义来自Facebook身份验证的回调：

passport.use(new FacebookStrategy({
clientID: FACEBOOK_APP_ID,
clientSecret: FACEBOOK_APP_SECRET,
callbackURL: ip + ":" + port + "/auth/facebook/callback"
},
  function(accessToken, refreshToken, profile, done) {
    // asynchronous verification, for effect...
    process.nextTick(function () {
      return done(null, profile);
    });
  }
));

It seems that Heroku doesn't know process.env.IP so I went ahead and defined a config var in Heroku:

似乎Heroku不知道process.env.IP所以我继续在Heroku中定义了一个config var：

heroku config:add process.env.IP=http://app.mydomain.com

Debugging the server I see that ip is not what I want but it's http://localhost same as I defined as the fallback in the first line of code.

调试服务器我发现ip不是我想要的，但它的http：// localhost与我在第一行代码中定义的回退相同。

How do I get node to read the config var correctly from heroku ?

如何让节点从heroku正确读取配置变量？

You want to use heroku config:set IP=http://app.mydomain.com; it defines an environment variable called IP, which you access in Node.js via process.env.IP. See Setting up config vars for a deployed application for more information.

你想使用heroku配置：set IP = http://app.mydomain.com;它定义了一个名为IP的环境变量，您可以通过process.env.IP在Node.js中访问它。有关更多信息，请参阅为已部署的应用程序设置配置变量。
