有没有什么办法与XMLHtt prequest对象发送二进制数据？ [英] Is there any way to send binary data with XMLHttpRequest object?

问题描述

我'尝试发送二进制块与XMLHtt prequest

I'am trying to send binary chunk with XMLHttpRequest

var xhr = new XMLHttpRequest();
var bindata = 0x0f0f;

xhr.open("POST", "binary_reader.php");

xhr.send(bindata);

但这种方法不能工作。我试图提供内容类型：应用程序/八位字节流，内容编码 对于 XHR头，他们没有任何工作。我很怀疑，有没有办法来编写这样那样的要求。

But this approach not works. I've tried to provide Content-type: application/octet-stream, Content-encoding headers for xhr and they don't work either. I am suspect that there is no way to compose request of such kind.

我想AP preciate任何帮助。

I would appreciate any help.

推荐答案

在最新规范。目前我还没有看到任何实施至今，但在不久的将来，这绝对是与XMLHtt prequest下载和上传的二进制数据的方式。

W3C has introduced Blob type to XMLHttpRequest in the latest specification. Currently I haven't seen any implementation so far but in near future this is definitely the way to download and upload binary data with XMLHttpRequest.
