srs 身份认证
用过很多免费的视频工具,从red5,crtmp到srs,总体来说srs还算比较完善的,比较稳定的。到止前为止,srs发布的稳定最新版srs 1.0r4 release,下面的测试都是根这个版本来进行的。
1,服务器说明
srs服务器 192.168.1.108
web服务器 192.168.1.208
2,srs文件配置目录/usr/local/srs/conf/
[root@localhostconf]# ll total 136 -rw-r--r-- 1 root root 402 Jun 24 09:34 bandwidth.conf -rw-r--r-- 1 root root 352 Jun 24 09:34 console.conf -rw-r--r-- 1 root root 558 Jun 24 09:34 demo.19350.conf -rw-r--r-- 1 root root 6045 Jun 24 09:34 demo.conf -rw-r--r-- 1 root root 399 Jun 24 09:34 dvr.segment.conf -rw-r--r-- 1 root root 335 Jun 24 09:34 dvr.session.conf -rw-r--r-- 1 root root 359 Jun 24 09:34 edge.conf -rw-r--r-- 1 root root 323 Jun 24 09:34 edge.token.traverse.conf -rw-r--r-- 1 root root 995 Jun 24 09:34 ffmpeg.transcode.conf -rw-r--r-- 1 root root 371 Jun 24 09:34 forward.master.conf -rw-r--r-- 1 root root 333 Jun 24 09:34 forward.slave.conf -rwxr-xr-x 1 root root 37388 Jun 24 09:34 full.conf -rw-r--r-- 1 root root 366 Jun 24 09:34 hls.conf -rw-r--r-- 1 root root 688 Jun 24 09:34 http.heartbeat.conf -rw-r--r-- 1 root root 471 Jun 24 09:34 http.hls.conf -rw-r--r-- 1 root root 874 Jun 24 09:34 http.hooks.callback.conf -rw-r--r-- 1 root root 589 Jun 24 09:34 ingest.conf -rw-r--r-- 1 root root 299 Jun 24 09:34 origin.conf -rw-r--r-- 1 root root 294 Jun 24 09:34 realtime.conf -rw-r--r-- 1 root root 225 Jun 24 09:34 rtmp.conf -rw-r--r-- 1 root root 1005 Aug 16 19:22 srs.conf //这个是进程启动时默认调用的配置 -rw-r--r-- 1 root root 819 Jun 24 09:34 transcode2hls.audio.only.conf
首先,先赞一下srs的配置说明,非常的全面,所有的配置都有实例,看一下官方文档,然后在该目录下找配置文件,很方便。
3,srs的认证配置
vhost __defaultVhost__ { 。。。。。。。。。。。。。。。。。。。。。 http_hooks { enabled on; # on_connect http://192.168.1.208/checkuser.php; # on_close http://192.168.1.208/checkuser.php; on_publish http://192.168.1.208/checkuser.php; # on_unpublish http://192.168.1.208/checkuser.php; on_play http://192.168.1.208/checkuser.php; # on_stop http://192.168.1.208/checkuser.php; } 。。。。。。。。。。。。。。。。。。。。。。。。。 }
在vhost中加上http_hooks,在发布rtmp流之前就会先去校验checkuser.php,根checkuser.php的返回,在决定是否能发布rtmp流。注意哦,可以验证多个服务器哦,也就是说,on_publish后的连接,可以多个,用空格分隔,full.conf中有详细的说明。
4,checkuser.php文件是在web服务器208
class checkuser { private $host = '192.168.1.208'; private $user = "dba"; private $pass = "111111"; private $database = 'srs'; private $db ; private $data ; public function __construct(){ $param = file_get_contents("php://input"); //$info下一行注释的内容 //'{"action":"on_publish","client_id":111,"ip":"192.168.1.108","vhost":"__defaultVhost__","app":"live","stream":"23948523485?key=13799999999_VVVXAaANX"}'; $this->data=json_decode($param); $this->error_l($param); if(!empty($this->data->action)){ $this->db = new ezSQL_mysql($this->user, $this->pass, $this->database, $this->host); $this->db->query("set names utf8;"); $this->checkUser(); }else{ echo "1"; } } public function checkUser(){ if ( $this->data->action == "on_connect"){ echo "0"; } else if ( $this->data->action == "on_close"){ echo "0"; } else if ( $this->data->action == "on_publish"){ $arr_query = $this->convertUrlQuery($this->data->stream); echo $arr_query; } else if ( $this->data->action == "on_unpublish"){ echo "0"; } else if ( $this->data->action == "on_play"){ echo "0"; } else if ( $this->data->action == "on_stop"){ echo "0"; } else if ( $this->data->action == "on_dvr"){ echo "0"; } else{ echo "1"; } die; } public function convertUrlQuery($query) { $m = '/key=(.*)/i'; preg_match($m,$query,$match); if(!empty($match[1])){ $info = explode('_',$match[1]); if(!empty($info[0]) && !empty($info[1])){ $result = $this->checkSrsLogin($info[0], $info[1]); if(!empty($result)){ return 0; }else{ return 1; } }else{ return 1; } }else{ return 1; } } public function checkSrsLogin ($account, $password) { if(empty($account) || empty($password)){ return false; } $sql = "select user_id from user ". " where password = '" . $password . "' and mobile = " . $account; $result = $this->db->get_row($sql); return $result; } public function error_l($param){ $message = "\r\n" . 'params: ' . $param . "\r\n" . 'Return Time : ' . date('Y-m-d H:i:s') . "\r\n"; $message .= '-----------------------------------------------------------------------------------------------' . "\r\n"; $path = getcwd()."/srs.log"; error_log($message, 3, $path); } }
5,利用ffmpeg发布rtmp的视频流,在108服务器
ffmpeg -re -i "/root/test.flv" -vcodec copy -acodec copy -f flv rtmp://192.168.1.108/live/23948523485?key=13799999999_VVVXAANX
rtmp流,为什么是这样形势呢。这是从full.conf文档中找到的,以下是full.conf文件中的部分内空
# when client connect to vhost/app, call the hook, # the request in the POST data string is a object encode by json: # { # "action": "on_connect", # "client_id": 1985, # "ip": "192.168.1.10", "vhost": "video.test.com", "app": "live", # "tcUrl": "rtmp://video.test.com/live?key=d2fa801d08e3f90ed1e1670e6e52651a", //看到了吧 # "pageUrl": "http://www.test.com/live.html" # } # if valid, the hook must return HTTP code 200(Stauts OK) and response # an int value specifies the error code(0 corresponding to success): # 0 # support multiple api hooks, format:
所以key后面的内容,就是要传递给checkuser.php的内容。
在这里要注意哦。key=xxxxx,这种形势是固定的哦,不支持key=xxxxxx&aaa=bbb。所以key后面,要传什么,要不要加密,自己决定了。
6,在208服务器看一下,srs.log信息
