php srs api,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

-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 = “”;

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”:”?key=_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/?key=_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
