Nginx模块之———— RTMP 模块的在线统计功能 stat 数据流数据的获取（不同节点则获取的方式不同）...

一、目前只有一个Live节点存在 

单节点获取方式如下：

public function getStreamByIp($outerIP, $streamName){//查询录像模块的ＩＰ地址外网，根据这个可以查看到相应的流$url = $outerIP . "/rtmp/stat";$ch = curl_init();curl_setopt($ch, CURLOPT_URL, $url);curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);curl_setopt($ch, CURLOPT_HEADER, 0);$output = curl_exec($ch);curl_close($ch);//所有流的信息,解析Xml$outputs = $this->FromXml($output); // $streamInfo = $outputs['server']['application']['live']['stream'];$streamInfo = $outputs['server']['application']['live']['stream'];if (array_key_exists("name", $streamInfo)) {//判断该设备是否在这个数组中，真：获取这个设备的所有打流信息if ($streamName == $streamInfo['name']) {$totalInfo['status'] = 200;$totalInfo['message'] = 'The server is normal and is currently streaming';$totalInfo['dataList']['name'] = $streamInfo['name'];$totalInfo['dataList']['bw_in'] = $streamInfo['bw_in'];$totalInfo['dataList']['bw_out'] = $streamInfo['bw_out'];} else {$totalInfo['status'] = 500;$totalInfo['message'] = 'The server has a problem or is not currently streaming information 1';$totalInfo['dataList']['name'] = $streamName;$totalInfo['dataList']['bw_in'] = 0;$totalInfo['dataList']['bw_out'] = 0;}} else {//存放所有的设备号到一个数组中foreach ($streamInfo as $key => $val) {$deviceInfo[] = $val['name'];}//判断该设备是否在这个数组中，真：获取这个设备的所有打流信息if (in_array($streamName, $deviceInfo)) {$totalInfo['status'] = 200;$totalInfo['message'] = 'The server is normal and is currently streaming';foreach ($streamInfo as $val) {if ($val['name'] == $streamName) {$totalInfo['dataList']['name'] = $val['name'];$totalInfo['dataList']['bw_in'] = $val['bw_in'];$totalInfo['dataList']['bw_out'] = $val['bw_out'];}}} else {$totalInfo['status'] = 500;$totalInfo['message'] = 'The server has a problem or is not currently streaming information 2';$totalInfo['dataList']['name'] = $streamName;$totalInfo['dataList']['bw_in'] = 0;$totalInfo['dataList']['bw_out'] = 0;}}return $totalInfo;}

二、目前有两个节点Live节点和Live2节点存在 

 多节点获取方式如下：

public function getStreamByIp($outerIP, $streamName){//查询录像模块的ＩＰ地址外网，根据这个可以查看到相应的流$url = $outerIP . "/rtmp/stat";$ch = curl_init();curl_setopt($ch, CURLOPT_URL, $url);curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);curl_setopt($ch, CURLOPT_HEADER, 0);$output = curl_exec($ch);curl_close($ch);//所有流的信息,解析Xml$outputs = $this->FromXml($output);$streamInfo = $outputs['server']['application'][0]['live']['stream']; //主要看这里哦！！！！！！！！！！！！！！！！这里获取的时候是一个二维数组if (array_key_exists("name", $streamInfo)) {//判断该设备是否在这个数组中，真：获取这个设备的所有打流信息if ($streamName == $streamInfo['name']) {$totalInfo['status'] = 200;$totalInfo['message'] = 'The server is normal and is currently streaming';$totalInfo['dataList']['name'] = $streamInfo['name'];$totalInfo['dataList']['bw_in'] = $streamInfo['bw_in'];$totalInfo['dataList']['bw_out'] = $streamInfo['bw_out'];} else {$totalInfo['status'] = 500;$totalInfo['message'] = 'The server has a problem or is not currently streaming information 1';$totalInfo['dataList']['name'] = $streamName;$totalInfo['dataList']['bw_in'] = 0;$totalInfo['dataList']['bw_out'] = 0;}} else {//存放所有的设备号到一个数组中foreach ($streamInfo as $key => $val) {$deviceInfo[] = $val['name'];}//判断该设备是否在这个数组中，真：获取这个设备的所有打流信息if (in_array($streamName, $deviceInfo)) {$totalInfo['status'] = 200;$totalInfo['message'] = 'The server is normal and is currently streaming';foreach ($streamInfo as $val) {if ($val['name'] == $streamName) {$totalInfo['dataList']['name'] = $val['name'];$totalInfo['dataList']['bw_in'] = $val['bw_in'];$totalInfo['dataList']['bw_out'] = $val['bw_out'];}}} else {$totalInfo['status'] = 500;$totalInfo['message'] = 'The server has a problem or is not currently streaming information 2';$totalInfo['dataList']['name'] = $streamName;$totalInfo['dataList']['bw_in'] = 0;$totalInfo['dataList']['bw_out'] = 0;}}return $totalInfo;}

三、解析Xml

public function FromXml($xml){if (!$xml) {$totalInfo['status'] = 500;$totalInfo['message'] = '没有该设备的相应信息';$totalInfo['dataList'] = null;return $totalInfo;}//将XML转为array$values = json_decode(json_encode(simplexml_load_string($xml, 'SimpleXMLElement', LIBXML_NOCDATA)), true);return $values;}

以上为在录像时候遇到问题，已经解决！
