如何使用javascript添加基本的keen.io事件

我正在尝试设置一个通过js发送自定义keen.io事件的基本示例。目前我不需要任何演示,可视化等。

我在网上找到的另一个创建的

Here is the example。我尝试了几种变体,所有这些变体都适用于谷歌浏览器,但它们都不适用于Firefox(38.0适用于Ubuntu规范 - 1.0)。

  1. 如果我在手册中添加了内联脚本(!function(a,b){a(“Keen”... ),我会这样做在FF中没有任何错误,但似乎 addEvent 永远不会被调用,它不会产生任何响应,“错误”也不会“res”。

  2. 如果我从CDN中包含该库( d26b395fwzu5fz.cloudfront.net/3.2.4/keen.min.js ),则在加载页面时出现错误:< / p>

    ReferenceError:没有定义Keen var keenClient = new Keen({

  3. 如果我下载js文件并在本地提供,在单击按钮后,我收到以下错误响应:

    错误:请求失败
    err = new Error(is_err?res.body.message:'发生未知错误');

  4. 所有这些尝试都适用于Chrome,但我也需要在其他浏览器中使用此功能。

答案 0 :(得分:3)

我收到了keen.io团队的回复。事实证明,Adblock Plus正在干扰脚本。禁用后,所有功能都可以在FF中使用。

经过一番调查后发现,对http://api.keen.io的请求被&#34; EasyPrivacy&#34;使用以下过滤规则过滤ABP:keen.io ^ $ third-party,domain = ~keen.github.io | ~keen.io

所以,向&#34;中间发送请求&#34;服务器(代理)似乎是我能看到的唯一解决方案。

我们有一个特定的用例 - 需要跟踪静态站点以及对rails api服务器的可用访问,但我们最终使用的解决方案可能对某人有用。

<强>的error.html

<html>
<head>
  <title>Error</title>
  <script src="/js/vendor/jquery-1.11.2.min.js"></script>
  <script src="/js/notification.js"></script>
  <script type="text/javascript">
    $(document).on('ready', function () {
      try {
        $.get(document.URL).complete(function (xhr, textStatus) {
          var code = xhr.status;
          if (code == 200) {
            var codeFromPath = window.location.pathname.split('/').reverse()[0].split('.')[0];
            if (['400', '403', '404', '405', '414', '416', '500', '501', '502', '503', '504'].indexOf(codeFromPath) > -1) {
              code = codeFromPath;
            }
          }
          Notification.send(code);
        });
      }
      catch (error) {
        Notification.send('error.html', error);
      }
    });
  </script>
</head>
<body>
There was an error. Site Administrators were notified.
</body>

<强> notification.js

var Notification = (function () {

  var endpoint = 'http://my-rails-server-com/notice';

  function send(type, jsData) {
    try {
      if (jsData == undefined) {
        jsData = {};
      }

      $.post(endpoint, clientData(type, jsData));
    }
    catch (error) {
    }
  }

  //  private
  function clientData(type, jsData) {
    return {
      data: {
        type: type,
        jsErrorData: jsData,
        innerHeight: window.innerHeight,
        innerWidth: window.innerWidth,
        pageXOffset: window.pageXOffset,
        pageYOffset: window.pageYOffset,
        status: status,
        navigator: {
          appCodeName: navigator.appCodeName,
          appName: navigator.appName,
          appVersion: navigator.appVersion,
          cookieEnabled: navigator.cookieEnabled,
          language: navigator.language,
          onLine: navigator.onLine,
          platform: navigator.platform,
          product: navigator.product,
          userAgent: navigator.userAgent
        },

        history: {
          length: history.length
        },
        document: {
          documentMode: document.documentMode,
          documentURI: document.documentURI,
          domain: document.domain,
          referrer: document.referrer,
          title: document.title,
          URL: document.URL
        },
        screen: {
          width: screen.width,
          height: screen.height,
          availWidth: screen.availWidth,
          availHeight: screen.availHeight,
          colorDepth: screen.colorDepth,
          pixelDepth: screen.pixelDepth
        },
        location: {
          hash: window.location.hash,
          host: window.location.host,
          hostname: window.location.hostname,
          href: window.location.href,
          origin: window.location.origin,
          pathname: window.location.pathname,
          port: window.location.port,
          protocol: window.location.protocol,
          search: window.location.search
        }
      }
    }
  }

  return {
    send: send
  }
}());

从js代码手动发送通知的示例:

try {
  // some code that may produce an error
}
catch (error) {
  Notification.send('name of keen collection', error);
}

# gemfile

#controller

    # response to Keen.publish does not include an ID of the newly added notification, so we add an identifier

    Keen.publish(data['type'], data) unless dev?(data)
