Angular JS中的IP白名單

Question

我正在使用AngularJS v1.2.32。

我想將基於IP的白名單列入合法系統。我已經搜索，但發現使用第三方json應用程序的例子。

需要通過JavaScript，angularjs獲取客戶端IP並限制對其他用戶的訪問。

非常感謝您的幫助。

Firefox和Chrome已經實現了WebRTC，允許向STUN服務器發送請求，以便爲用戶返回本地和公共IP地址。這些請求結果可用於JavaScript，因此您現在可以通過javascript獲取用戶本地和公共IP地址。這個演示是一個示例實現。 更多

    var servers = {iceServers: [{urls: "stun:stun.services.mozilla.com"}]}; 
 

 
    //construct a new RTCPeerConnection 
 
    var pc = new RTCPeerConnection(servers, mediaConstraints); 
 

 
    function handleCandidate(candidate){ 
 
     //match just the IP address 
 
     var ip_regex = /([0-9]{1,3}(\.[0-9]{1,3}){3}|[a-f0-9]{1,4}(:[a-f0-9]{1,4}){7})/ 
 
     var ip_addr = ip_regex.exec(candidate)[1]; 
 

 
     //remove duplicates 
 
     if(ip_dups[ip_addr] === undefined) 
 
      callback(ip_addr); 
 

 
     ip_dups[ip_addr] = true; 
 
    } 
 

 
    //listen for candidate events 
 
    pc.onicecandidate = function(ice){ 
 

 
     //skip non-candidate events 
 
     if(ice.candidate) 
 
      handleCandidate(ice.candidate.candidate); 
 
    }; 
 

 
    //create a bogus data channel 
 
    pc.createDataChannel(""); 
 

 
    //create an offer sdp 
 
    pc.createOffer(function(result){ 
 

 
     //trigger the stun server request 
 
     pc.setLocalDescription(result, function(){}, function(){}); 
 

 
    }, function(){}); 
 

 
    //wait for a while to let everything done 
 
    setTimeout(function(){ 
 
     //read candidate info from local description 
 
     var lines = pc.localDescription.sdp.split('\n'); 
 

 
     lines.forEach(function(line){ 
 
      if(line.indexOf('a=candidate:') === 0) 
 
       handleCandidate(line); 
 
     }); 
 
    }, 1000); 
 
} 
 

 
//Test: Print the IP addresses into the console 
 
getIPs(function(ip){console.log(ip);});
