后台代码:
public ActionResult Video()
{
string filePath = @"D:\download\test.mp4";
System.IO.FileInfo fileInfo = new System.IO.FileInfo(filePath);
if (fileInfo.Exists == true)
{
FileStream fs = new FileStream(filePath, FileMode.Open);
byte[] bytes = new byte[(int)fs.Length];
fs.Read(bytes, , bytes.Length);
fs.Close(); //Response.AddHeader("Content-Disposition", "attachment; filename=" + HttpUtility.UrlEncode(fileInfo.Name));
Response.AddHeader("Content-Length", "" + fileInfo.Length.ToString());
Response.AddHeader("Content-Transfer-Encoding", "binary");
Response.ContentType = "application/octet-stream";
Response.ContentEncoding = System.Text.Encoding.UTF8;
Response.BinaryWrite(bytes);
Response.Flush();
Response.End();
}
}
前台代码:
html: <video id="video_player" width="" height="" controls="controls"></video> Js:
//创建XMLHttpRequest对象
var xhr = new XMLHttpRequest();
//配置请求方式、请求地址以及是否同步
xhr.open('POST', 'Video', true);
//设置请求结果类型为blob
xhr.responseType = 'blob';
//请求成功回调函数
xhr.onload = function (e) {
if (this.status == ) {//请求成功
//获取blob对象
var blob = this.response;
var video = document.getElementById('video_player');
//获取blob对象地址,并把值赋给容器
var obj_url = window.URL.createObjectURL(blob);
video.src = obj_url;
//video.play();
setTimeout("revokeUrl('" + obj_url + "')", "");
}
};
xhr.send(); function revokeUrl(url) {
window.URL.revokeObjectURL(url);
}
