Internet Explorer 和 Safari - 如果没有可用的 WebRTC 默认值，我如何使用我的防火墙暂停

Question

我正在尝试为那些没有默认WebRTC的用户制作防火墙/过滤器，在我的域中将被暂停5年，作为社区，我们正在尽可能多地暂停。

那么，我该如何检测

IE手机版

和

iOS 野生动物园

用户？我想在我的防火墙列表中挂起，因为它们默认情况下没有webRTC并且总是提出投诉。

  waitForWhichBrowser(function() {
    var o = document.getElementById('container');
    try {
      Browsers = new WhichBrowser({
        useFeatures:        true,
        detectCamouflage:   true
      });
      var n = Browsers.browser.name;
      var v = Browsers.browser.version.major;
      var oo = Browsers.os;
      var d = Browsers.isType('desktop'); // true
      //var a = Browsers.isType('mobile', 'tablet', 'media');   // false
      o.innerHTML = 'Using ' + Browsers + '<br/><small>Desktop PC: ' + d  +  ' ' + oo +  '</small>';            
      var g = document.getElementById('getit');     
      if (n == "Chrome") {
        if (v < 32 ) {           
          g.innerHTML = "No WebRTC. Community Suspended this browser for 5 years. Please use  https://www.google.com/intl/en/chrome/browser/";  
        }
      } else if (n == "Chromium") {
        if (v < 31 ) {
          g.innerHTML = "UDP BUG - No WebRTC. Community Suspended this browser for 5 years. Please use  https://www.google.com/intl/en/chrome/browser/";   
        }   
      } else if (n == "Opera") {        
        if (v <19 ) {
          // suspend them
        }
      } else if (n == "Internet Explorer") {
          g.innerHTML = "No WebRTC. Community Suspended this browser for 5 years. Please use  https://www.google.com/intl/en/chrome/browser/";        
      } else if (n == "Firefox") {
          g.innerHTML = "UDP BUG - No WebRTC available by default suspend it. Community Suspend, No WebRTC No standard web browser. Suspended this browser for 5 years. Please use https://www.google.com/intl/en/chrome/browser/";               
      } else if (n == "Safari") {
          g.innerHTML = "No WebRTC. Community Suspended this browser for 5 years. Please use  https://www.google.com/intl/en/chrome/browser/";            
      } else {

      }
    } catch (e) {
      o.innerHTML = 'Oops, something went wrong:<br> <small>' + e + '</small>';
    }
  });

我建议您进行功能检测而不是浏览器检测来决定挂起哪些浏览器。因此，下面给出的简单代码应该足以满足您的需求：

if(window.mozRTCPeerConnection || window.webkitRTCPeerConnection) {
    //supported
} else {
    //unsupported
}
