}

HTTP callback events（回调事件）

SRS的回调事件包括：

事件 数据 说明
on_connect {
"action": "on_connect",
"client_id": 1985,
"ip": "192.168.1.10",
"vhost": "video.test.com",
"app": "live",
"tcUrl": "rtmp://x/x?key=xxx",
"pageUrl": "http://x/x.html"
} 		当客户端连接到指定的vhost和app时
on_close {
"action": "on_close",
"client_id": 1985,
"ip": "192.168.1.10",
"vhost": "video.test.com",
"app": "live",
"send_bytes": 10240,
"recv_bytes": 10240
} 		当客户端关闭连接，或者SRS主动关闭连接时
on_publish {
"action": "on_publish",
"client_id": 1985,
"ip": "192.168.1.10",
"vhost": "video.test.com",
"app": "live",
"stream": "livestream"
} 		当客户端发布流时，譬如flash/FMLE方式推流到服务器
on_unpublish {
"action": "on_unpublish",
"client_id": 1985,
"ip": "192.168.1.10",
"vhost": "video.test.com",
"app": "live",
"stream": "livestream"
} 		当客户端停止发布流时
on_play {
"action": "on_play",
"client_id": 1985,
"ip": "192.168.1.10",
"vhost": "video.test.com",
"app": "live",
"stream": "livestream",
"pageUrl": "http://a.com/i.html",
"param":"?k=v"
} 		当客户端开始播放流时
on_stop {
"action": "on_stop",
"client_id": 1985,
"ip": "192.168.1.10",
"vhost": "video.test.com",
"app": "live",
"stream": "livestream"
} 		当客户端停止播放时。备注：停止播放可能不会关闭连接，还能再继续播放。
on_dvr {
"action": "on_dvr",
"client_id": 1985,
"ip": "192.168.1.10",
"vhost": "video.test.com",
"app": "live",
"stream": "livestream",
"cwd": "/opt",
"file": "./l.xxx.flv"
}

当DVR录制关闭一个flv文件时

其中，

  • 事件：发生该事件时，即回调指定的HTTP地址。
  • HTTP地址：可以支持多个，以空格分隔，SRS会依次回调这些接口。
  • 数据：SRS将数据POST到HTTP接口。
  • 返回值：SRS要求HTTP服务器返回HTTP200并且response内容为整数错误码（0表示成功），其他错误码会断开客户端连接。

    我们可以根据以上的回调事件处理自己的业务代码。

3、回调测试

SRS HTTP Callback Server

SRS自带了一个默认的处理HTTP Callback的服务器，启动时需要指定端口，譬如8085端口。

启动方法：python research/api-server/server.py 8085

启动日志如下：

[winlin@dev6 srs]$ python research/api-server/server.py 8085
[2014-02-27 09:42:25][trace] api server listen at port: 8085, static_dir: /home/winlin/git/srs/trunk/research/api-server/static-dir
[2014-02-27 09:42:25][trace] start cherrypy server
[27/Feb/2014:09:42:25] ENGINE Listening for SIGHUP.
[27/Feb/2014:09:42:25] ENGINE Listening for SIGTERM.
[27/Feb/2014:09:42:25] ENGINE Listening for SIGUSR1.
[27/Feb/2014:09:42:25] ENGINE Bus STARTING
[27/Feb/2014:09:42:25] ENGINE Started monitor thread '_TimeoutMonitor'.
[27/Feb/2014:09:42:25] ENGINE Started monitor thread 'Autoreloader'.
[27/Feb/2014:09:42:25] ENGINE Serving on 0.0.0.0:8085
[27/Feb/2014:09:42:25] ENGINE Bus STARTED

Publish and Play

推流到SRS时，会调用HTTP接口：

[2014-02-27 09:41:33][trace] post to clients, req={"action":"on_connect","client_id":4,"ip":"192.168.1.179","vhost":"__defaultVhost__","app":"live","pageUrl":""}
[2014-02-27 09:41:33][trace] srs on_connect: client id=4, ip=192.168.1.179, vhost=__defaultVhost__, app=live, pageUrl=
127.0.0.1 - - [27/Feb/2014:09:41:33] "POST /api/v1/clients HTTP/1.1" 200 1 "" "srs(simple rtmp server)0.9.2"

播放SRS的流时，也会调用HTTP接口：

[2014-02-27 09:41:50][trace] post to clients, req={"action":"on_connect","client_id":5,"ip":"192.168.1.179","vhost":"__defaultVhost__","app":"live","pageUrl":"http://dev.chnvideo.com:3080/players/rtmp/"}
[2014-02-27 09:41:50][trace] srs on_connect: client id=5, ip=192.168.1.179, vhost=__defaultVhost__, app=live, pageUrl=http://dev.chnvideo.com:3080/players/rtmp/
127.0.0.1 - - [27/Feb/2014:09:41:50] "POST /api/v1/clients HTTP/1.1" 200 1 "" "srs(simple rtmp server)0.9.2"
