保存到一定时间后Web服务器

本文介绍了HTML5&安培; getUserMedia - 录音和放;保存到一定时间后Web服务器的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我有一些困难getUserMedia用HTML5开发的同时我的网页。这是我第一次尝试实现这个记录一个用户的音频输入。 Flash是不是这个项目的选择,因为它必须在移动设备上使用过

我来这里看看,如果任何人有经验,知道如何实现与getUserMedia的HTML5记录了一定的时间(在PHP中的会话完成)一个用户的麦克风,然后保存和音频文件发送到Web服务器

如果这是不可能的,那么有没有任何其他的方式,或许与Java小程序?

JS的:

 <脚本>
      VAR onFail =功能(E){
        的console.log('拒绝!',E);
      };      变种的onSuccess =函数(多个){
        VAR语境=新webkitAudioContext();
        VAR MediaStreamSource的= context.createMediaStreamSource(S);
        记录=新记录(MediaStreamSource的);
        recorder.record();        //音频回环
        // mediaStreamSource.connect(context.destination);
      }      window.URL = window.URL || window.webkitUR​​L;
      navigator.getUserMedia = navigator.getUserMedia || navigator.webkitGetUserMedia || navigator.mozGetUserMedia || navigator.msGetUserMedia;      VAR记录;
      VAR音频= document.querySelector('声音');      功能的startRecording(){
        如果(navigator.getUserMedia){
          navigator.getUserMedia({音频:真正}的onSuccess,onFail);
        }其他{
          的console.log('navigator.getUserMedia不是present');
        }
      }      功能STO precording(){
        recorder.stop();
        recorder.exportWAV(功能(S){
          audio.src = window.URL.createObjectURL(S);
        });
      }
    < / SCRIPT>

中的HTML(与从):

 <脚本类型=文/ JavaScript的SRC =recorder.js> < / SCRIPT>    <输入的onclick =的startRecording()类型=按钮值=开始录制>
    <输入的onclick =STO precording()类型=按钮值=停止录制和播放>


解决方案

可以使用XMLHtt prequest

 函数上传(blobOrFile){
    VAR XHR =新XMLHtt prequest();
    xhr.open('POST','/upload.aspx',真);
    xhr.onload =功能(E){
        VAR的结果= e.target.result;
    };    xhr.send(blobOrFile);
}//停止录制函数调用上传方法
//我使用recorder.jsrecorder.exportWAV(功能(BLOB){
    VAR URL = URL.createObjectURL(BLOB);
    audio.src =网址;
    audio.controls = TRUE;
    VAR HF =使用document.createElement('A');
    hf.href =网址;
    hf.download =新的日期()toISOString()+'.WAV。
    上传(BLOB);
});//服务器端ASPX页面加载 - 可以节省服务器.wav文件Request.SaveAs(使用Server.Mappath(/富/+1+.WAV),FALSE);

I'm having some difficulties with getUserMedia with HTML5 whilst developing my web page. This is the first time I've tried to implement this to record a users audio input. Flash is not an option for this project as it has to be used on mobile devices too.

I come here to see if anyone has experience with and knows how to implement an HTML5 with getUserMedia to record a users microphone for a certain amount of time (done with a session in PHP) and then saves and sends the audio file to a web server.

If this isn't possible then is there any other way, perhaps with a Java applet?

The js:

<script>
      var onFail = function(e) {
        console.log('Rejected!', e);
      };

      var onSuccess = function(s) {
        var context = new webkitAudioContext();
        var mediaStreamSource = context.createMediaStreamSource(s);
        recorder = new Recorder(mediaStreamSource);
        recorder.record();

        // audio loopback
        // mediaStreamSource.connect(context.destination);
      }

      window.URL = window.URL || window.webkitURL;
      navigator.getUserMedia  = navigator.getUserMedia || navigator.webkitGetUserMedia || navigator.mozGetUserMedia || navigator.msGetUserMedia;

      var recorder;
      var audio = document.querySelector('audio');

      function startRecording() {
        if (navigator.getUserMedia) {
          navigator.getUserMedia({audio: true}, onSuccess, onFail);
        } else {
          console.log('navigator.getUserMedia not present');
        }
      }

      function stopRecording() {
        recorder.stop();
        recorder.exportWAV(function(s) {
          audio.src = window.URL.createObjectURL(s);
        });
      }
    </script>

The HTML (linked to recorder.js from here):

    <script type="text/javascript" src="recorder.js"> </script>

    <input onclick="startRecording()" type="button" value="start recording">
    <input onclick="stopRecording()" type="button" value="stop recording and play">
解决方案

can use XMLHttpRequest

function upload(blobOrFile) {
    var xhr = new XMLHttpRequest();
    xhr.open('POST', '/upload.aspx', true);
    xhr.onload = function (e) {
        var result = e.target.result;
    };

    xhr.send(blobOrFile);
}

// stop recording function calls the upload method
// I am using recorder.js

recorder.exportWAV(function (blob) {
    var url = URL.createObjectURL(blob);
    audio.src = url;
    audio.controls = true;
    var hf = document.createElement('a');
    hf.href = url;
    hf.download = new Date().toISOString() + '.wav';
    upload(blob);
});

// on server side ASPX pageload - can save .wav file on server

Request.SaveAs(Server.MapPath("/foo/" + "1" + ".wav"), false);
