OpenTok NodeJS 视频聊天

Question

我一直在关注这个https://github.com/songz/OpenTokNodeJS项目。

我已经提交了一个问题，但我想在这里尝试一下。

我一直在努力让它运行起来，但似乎无法成功。 这是我的错误信息。

我猜可能与我的API密钥有关，而且说实话，我甚至不确定应该把它放在哪里。我尝试了几种方法。首先，我替换了app.js中的行：

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

使用以下内容：

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

但是当我运行$ node app.js时，什么也没有发生，我遇到了错误

我还尝试将key和secret添加到package.json文件中，如下所示

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

但我还是遇到了同样的错误。有什么想法吗？

感谢您制作这个，看起来很棒，迫不及待想让它运行起来！

我的名字是宋，我相信我能帮助你。当我写下以下代码时，我只是在设置变量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的值，方法如下：

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

process.env.TB_KEY 和 process.env.TB_SECRET 是从我的系统环境中提取变量的方法。我之所以这样做是因为安全原因（我不想意外将我的密钥/密码推送到Github）。要为您的系统环境设置变量，请打开您的bash配置文件并添加以下行：

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

再次强调，设置环境变量并不是让您的代码工作所必需的。最简单的方法是只设置OTKEY和OTSECRET这两个变量。

祝好运！
