我如何...将记录的blob发送到Web服务 [英] How do I...send a recorded blob to a web service

问题描述

我有一个当前存储在内存中的blob，我想要一种获取该blob并将其发送到Web服务的方法。任何形式的帮助将不胜感激。



以下代码在我的recorder.js中发送blob到服务器

I have a blob which currently is stored in memory, I would like a way to get that blob and send it to a web service. Any kind of help would be appreciated.

the following code is in my recorder.js to send blob to server

Recorder.sendFile = function(cb, filename) {
    var uri = "http://localhost/TestWebService/UploadService.asmx?op=UploadAudio";
    var xhr = new XMLHttpRequest();

    xhr.open("POST", uri, true);
    xhr.onreadystatechange = function() {
        if (xhr.readyState == 4 && xhr.status == 200) {
           // Handle response.
           alert(xhr.responseText); // handle response.
        }
    };
    xhr.send(cb);
  }

i从main.js中的recorder.js调用函数

i call the function from the recorder.js in main.js

function sendAudio() {
    Recorder.sendFile( doneEncoding );
}

i在html中调用方法

i call the method in html

<button  önclick="saveAudio(this);"></button>

i使用方法来检索我的网络服务中的blob

i use the method to retrieve the blob in my web service

public string UploadAudio(byte[] file)
    {
        string straudioPath;
        straudioPath = "~App_Data/";
        FileStream objfilestream = new FileStream(straudioPath, FileMode.Create, FileAccess.ReadWrite);
        objfilestream.Write(file, 0, file.Length);
        objfilestream.Close();

        return "OK";
    }
