我将我的歌曲存储在数据库中作为bytes []。如何在<audio>
标记中使用这些内容。
这样的事情。我是否需要先将字节转换为其他内容?我不确定。
foreach (var item in Model)
{
<audio controls>
<source src=@item.SongBytes type="audio/mp3"/>
</audio>
}

一种方法是在控制器中添加一个返回数据的新操作:
public ActionResult Audio(int someId)
{
byte[] songBytes;
// Add code to get data
return new FileStreamResult(songBytes, "audio/mp3");
}
然后将URL添加到src属性中:
foreach (var item in Model)
{
<audio controls>
<source src="/Controller/Audio/@item.someId" type="audio/mp3"/>
</audio>
}

Google Chrome / Ipad需要支持内容范围请求,因此要在此添加给定答案,请执行以下操作:
public FileStreamResult StreamUploadedSongs(int id)
{
byte[] song = db.UploadedSongs.Where(x => x.Id == id).FirstOrDefault().SongBytes;
long fSize = song.Length;
long startbyte = 0;
long endbyte = fSize - 1;
int statusCode = 200;
if ((Request.Headers["Range"] != null))
{
//Get the actual byte range from the range header string, and set the starting byte.
string[] range = Request.Headers["Range"].Split(new char[] { '=', '-' });
startbyte = Convert.ToInt64(range[1]);
if (range.Length > 2 && range[2] != "") endbyte = Convert.ToInt64(range[2]);
//If the start byte is not equal to zero, that means the user is requesting partial content.
if (startbyte != 0 || endbyte != fSize - 1 || range.Length > 2 && range[2] == "")
{ statusCode = 206; }//Set the status code of the response to 206 (Partial Content) and add a content range header.
}
long desSize = endbyte - startbyte + 1;
//Headers
Response.StatusCode = statusCode;
Response.ContentType = "audio/mp3";
Response.AddHeader("Content-Accept", Response.ContentType);
Response.AddHeader("Content-Length", desSize.ToString());
Response.AddHeader("Content-Range", string.Format("bytes {0}-{1}/{2}", startbyte, endbyte, fSize));
//Data
var stream = new MemoryStream(song, (int)startbyte, (int)desSize);
return new FileStreamResult(stream, Response.ContentType);
}

它对我有用,我的问题是,当我尝试通过Chrome中的waveurfer.js通过调用控制器方法播放.wav文件时,该控制器方法返回ActionResult然后播放文件,但我无法向前,向后搜索。当我搜索时,玩家将返回起始位置。尽管此功能在Firfox中正常运行。
