将ueditor上传的视频转换为flowplayer播放，并隐藏其播放地址

1、在页面引用flowplayer-min.js；

2、将ueditor上传的video标签内容转换成div标签内容，替换后的内容形式如下：

<div src="videoReplaceUrl" style="height:400px;" class="video-js"></video>

3、用jquery遍历class为video-js的div，注册flowplayer播放元素；

/*遍历*/
var video_index = 1;
        $(".video-js").each(function()
        {
            var divVideoId = "divVideo" + video_index;
            $(this).attr("id", divVideoId);
            var videoUrl = $(this).attr("src");
            changeToFlowplayer(videoUrl, divVideoId);
            video_index++;
         });

/*转换成flowplayer播放*/
function changeToFlowplayer(videoUrl, divVideoId)
    {
        var ts = new Date().getTime()/1000;
        ts = ts.toString(16);
        ts = ts.split(".")[0];
        var playing = false;
        var autoPlay = false;
        
        flowplayer(
            divVideoId,
            "/xxx/flowplayer/flowplayer-3.2.8.swf",
            {
                plugins: {
                    secure: {
                        url: 'flowplayer.securestreaming-3.2.3.swf',
                        timestamp: ts,
                        token: "xxxxx"
                    }
                },
                clip:{
                    autoPlay: autoPlay,
                    autoBuffering: false,
                    urlResolvers: 'secure',
                    baseUrl: '/swf-play',
                    onStart : function() {
                        if(!playing && typeof(playCallBack)=='function'){
                            playCallBack();
                            playing = true;
                        }
                    }
                },
                  playlist: [videoUrl]
            }
        );
    }

4、当使用flowplayer播放上时，会生成如下形式url：

http://navy.com/swf-play/05538e221a147e28d206378e66740058/55e3ca51/1440758930760

这时已经达到隐藏url的目的，其中05538e221a147e28d206378e66740058为ts、token、videoUrl通过md5加密生成。ts:55e3ca51;videoUrl:1440758930760

5、接下来就是针对伪url进行处理；

在nginx下，对伪url进行重写操作，让它跳转到处理的swf-play.action中。

rewrite  ^/swf-play/([0-9a-zA-Z]+)/([0-9a-zA-Z]+)/([0-9a-zA-Z\.]+)$ /swf-play.action?ts=$2&token=$1&name=$3 last;

6、在swf-play.action中拿到ts、token、name进行解密验证，以判断该请求是否通过，如通过，读取视频流，写到结果里面，播放视频。

//验证
String hashSalt = getHashSalt();
String temp = DigestUtils.md5Hex(hashSalt + "/" + name + ts);
boolean result = temp.equals(this.token);
return result;

//返回视频流
BufferedInputStream bis = null;
ServletOutputStream os = null;
File f = null;
f = new File(realPath);
bis = new BufferedInputStream(new FileInputStream(f));
int available = bis.available();
HttpServletResponse response = getResponse();
response.setContentType("application/x-shockwave-flash");
response.addHeader("x-app", "xxx");
response.addHeader("Content-Length", f.length() + "");
response.addHeader("Cache-Control", "private");
os = response.getOutputStream();
byte[] b = new byte[1024];
int begin = 0;
int readCount = 0;
while (begin <= available) {
	readCount = bis.read(b);
	if (readCount <= 0) {
		break;
        }
	os.write(b, 0, readCount);
	begin += readCount;
}
