Tomcat服务器在192.168.2.111，编写了页面调用：
<!DOCTYPE html>
<html lang="en" dir="ltr">
<head>
<title></title>
<meta charset="utf-8">
<link href="/@6.11.0/dist/" rel="stylesheet">
</head>
<script src="/@6.11.0/dist/"></script>
<script src="/videojs-flash/dist/"></script>
<script src="/videojs-contrib-hls/dist/"></script>
<body>
<video class="video-js" controls>
<source src="http://192.168.2.112:8080/hls/1000246_2_2.m3u8" type="application/x-mpegURL">
<p class="vjs-no-js">not support</p>
</video>
<script type="text/javascript">
var player = videojs('my-player', {
width : 400,
heigh : 200
});
</script>
</body>
</html>
在主机192.168.2.112用了nginx搭建hls流媒体服务器，生成了m3u8，但是用访问的时候出现提示：
Access to XMLHttpRequest at 'http://192.168.2.112:8080/hls/1000246_2_2.m3u8' from origin 'http://localhost:9999' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.
因为Tomcat的访问URL里是：
http://localhost:9999/xxxx/或者http://192.168.2.111:9999/xxxx/，和m3u8所在192.168.2.112域名不一致。
解决办法，配置112上的nginx，（蓝色是新增）：
worker_processes 1;
error_log logs/ info;
events {
worker_connections 1024;
}
rtmp {
server {
listen 1935;
application live {
live on;
}
application hls {
live on;
hls on;
hls_path temp/hls;
hls_fragment 8s;
}
}
}
http {
server {
listen 8080;
location / {
root html;
}
location /stat {
rtmp_stat all;
rtmp_stat_stylesheet ;
}
location / {
root html;
}
location /hls {
#server hls fragments
types{
application/ m3u8;
video/mp2t ts;
}
alias temp/hls;
expires -1;
add_header Access-Control-Allow-Origin *;
add_header Access-Control-Allow-Headers X-Requested-With;

}
