直播推流地址和播放地址本身没有API接口，需要在客户端自行拼接地址，然后使用推流工具或者播放器对其推流或播放。本文主要介绍如何生成直播的推流以及播放地址。

PHP代码示例

视频直播生成推流地址和播放地址的PHP示例代码如下所示。?php

function push_url($push_domain,$push_key,$expireTime,$appName,$streamName){

$push_url = '';

//未开启鉴权Key的情况下

if($push_key==''){

$push_url = 'rtmp://'.$push_domain.'/'.$appName.'/'.$streamName;

echo $push_url;

return;

}

$timeStamp = time() + $expireTime;

$sstring = '/'.$appName.'/'.$streamName.'-'.$timeStamp.'-0-0-'.$push_key;

$md5hash = md5($sstring);

$push_url = 'rtmp://'.$push_domain.'/'.$appName.'/'.$streamName.'?auth_key='.$timeStamp.'-0-0-'.$md5hash;

echo $push_url;

echo PHP_EOL;

return;

}

function play_url($play_domain,$play_key,$expireTime,$appName,$streamName){

//未开启鉴权Key的情况下

if($play_key==''){

$rtmp_play_url = 'rtmp://'.$play_domain.'/'.$appName.'/'.$streamName;

$flv_play_url = 'http://'.$play_domain.'/'.$appName.'/'.$streamName.'.flv';

$hls_play_url = 'http://'.$play_domain.'/'.$appName.'/'.$streamName.'.m3u8';

}else{

$timeStamp = time() + $expireTime;

$rtmp_sstring = '/'.$appName.'/'.$streamName.'-'.$timeStamp.'-0-0-'.$play_key;

$rtmp_md5hash = md5($rtmp_sstring);

$rtmp_play_url = 'rtmp://'.$play_domain.'/'.$appName.'/'.$streamName.'?auth_key='.$timeStamp.'-0-0-'.$rtmp_md5hash;

$flv_sstring = '/'.$appName.'/'.$streamName.'.flv-'.$timeStamp.'-0-0-'.$play_key;

$flv_md5hash = md5($flv_sstring);

$flv_play_url = 'http://'.$play_domain.'/'.$appName.'/'.$streamName.'.flv?auth_key='.$timeStamp.'-0-0-'.$flv_md5hash;

$hls_sstring = '/'.$appName.'/'.$streamName.'.m3u8-'.$timeStamp.'-0-0-'.$play_key;

$hls_md5hash = md5($hls_sstring);

$hls_play_url = 'http://'.$play_domain.'/'.$appName.'/'.$streamName.'.m3u8?auth_key='.$timeStamp.'-0-0-'.$hls_md5hash;

}

echo 'rtmp播放地址: '.$rtmp_play_url;

echo PHP_EOL;

echo 'flv播放地址: '.$flv_play_url;

echo PHP_EOL;

echo 'hls播放地址: '.$hls_play_url;

echo PHP_EOL;

return;

}

//推流域名

$push_domain = 'testpush.cn';

//推流域名配置的鉴权Key

$push_key = 'test_Push_key';

//生成随机的AppName

$appName = md5(uniqid(microtime(true),true));

//生成随机的StreamName

$streamName = md5(uniqid(microtime(true),true));

//配置过期时间为1小时

$expireTime = 3600;

//播放域名

$play_domain = 'testPlay.cn';

//播放域名配置的鉴权Key

$play_key = 'test_play_key';

push_url($push_domain,$push_key,$expireTime,$appName,$streamName);

play_url($play_domain,$play_key,$expireTime,$appName,$streamName);

?>

Java代码示例

return null;

}

try {

MessageDigest md5 = MessageDigest.getInstance("MD5");

md5.update(param.getBytes());

byte[] byteArray = md5.digest();

BigInteger bigInt = new BigInteger(1, byteArray);

// 参数16表示16进制

String result = bigInt.toString(16);

// 不足32位高位补零

while(result.length() < 32) {

result = "0" + result;

}

return result;

} catch (NoSuchAlgorithmException e) {

e.printStackTrace();

}

return null;

}
