Question

我一直在跟着这个 https://github.com/songz/OpenTokNodeJS

我发布了一个问题，但我想我也会尝试一下。

我已经在这工作了一分钟，似乎无法让它运行。这是我的错误

我猜这与我的api密钥有关，说实话，我不是100％，我甚至应该把它放在那里。我尝试过几种方法。首先，我替换了app.js中的行

var OTKEY = process.env.TB_KEY; var OTSECRET = process.env.TB_SECRET;

与

var OTKEY = (my api key);
var OTSECRET = (my secret);

但是当我运行$ node app.js时，没有任何反应，我收到了错误

我也尝试过将密钥和密码添加到package.json文件中，如此

{
    "name":"NodeOpenTok",
    "version":"0.0.2",
    "dependencies":{
      "opentok":"44456952",
      "express":"7f2ecae114cd4095a1ed689ff63910f1ea79444b",
      "ejs":""
    }
}

但是我得到了同样的错误。任何想法？

感谢你做这个，看起来很棒，迫不及待地想让它发挥作用！

我的名字是宋，我相信我可以帮助你。当我编写以下代码时，我只是设置变量OTKEY和OT_SECRET。

var OTKEY = process.env.TB_KEY; 
var OTSECRET = process.env.TB_SECRET;

您可以直接替换密钥和密钥：

var OTKEY = "1234";
var OTSECRET = "1abbababaabcabc";

process.env.TB_KEY和process.env.TB_SECRET从我的系统环境中提取变量。我这样做是出于安全原因（我不想意外地将我的密钥/秘密推送到github）。要为系统环境设置变量，请打开bash配置文件并添加以下行：

export TB_KEY='1234'
export TB_SECRET='1abbababaabcabc'

同样，设置环境变量不是让代码工作所必需的。最简单的方法是简单地设置变量OTKEY和OTSECRET。

祝你好运！
