所以我指的是将Chrome中记录的WAV文件保存到服务器,以将blob保存到我的服务器。但是,我无法将此PHP句子转换为C#。
<?php
// get the temporary name that PHP gave to the uploaded file
$tmp_filename=$_FILES["that_random_filename.wav"]["tmp_name"];
// rename the temporary file (because PHP deletes the file as soon as it's done with it)
rename($tmp_filename,"/tmp/uploaded_audio.wav");
?>
这是我到目前为止尝试过的
视图
var fd = new FormData();
fd.append("that_random_filename.wav", blob);
xhr.open("POST", "SubmitSound", true);
xhr.send(fd);
查看模型
public class SoundBlob
{
public string key { get; set; }
public HttpPostedFileBase blob { get; set; } // I tried byte[] and string too
}
控制器
[HttpPost]
public ActionResult SubmitSound(SoundBlob blob)
{
// Create the new, empty data file.
string fileName = AppDomain.CurrentDomain.BaseDirectory + "/Content/Sound/" + Environment.TickCount + ".wav";
FileStream fs = new FileStream(fileName, FileMode.CreateNew);
BinaryWriter w = new BinaryWriter(fs);
blob.blob.SaveAs(blob.key);
w.Close();
fs.Close();
return new JsonResult() { Data = "Saved successfully" };
}
SoundBlob
的key
和blob
都是空的!我该如何解决它?
不依赖于 C# 类型,而是使用此脚本。
var length = Request.ContentLength;
var bytes = new byte[length];
Request.InputStream.Read(bytes, 0, length);
试试这个:
客户:
<script src="http://code.jquery.com/jquery-1.10.2.min.js" ></script>
<div class='wrapper' >
<input type='file' class='target' id='targetinput' />
</div>
Javascript:
var xhr = new XMLHttpRequest();
var fd = new FormData();
fd.append("blob.blob", document.getElementById('targetinput').files[0]);
xhr.open("POST", "/Home/SubmitSound", true);
xhr.send(fd);
服务器:
[HttpPost]
public ActionResult SubmitSound(SoundBlob blob)
{
var fileName = Server.MapPath(string.Format("/Content/Sound/{0}.wav", Environment.TickCount));
blob.blob.SaveAs(fileName);
return new JsonResult { Data = "Saved successfully" };
}
完美有效,我刚刚检查出来
