Question

我正在研究PHP / HTML脚本。

我希望在歌曲改变时使用自动刷新来获取Shoutcast流的当前歌曲。

Shoutcast不允许HTTP请求，因此我使用此脚本将页面放入另一个文件中：

<?php
$lurl=get_fcontent("http://5.135.39.189:8000/");
echo"cid:".$lurl[0]."<BR>";


function get_fcontent( $url,  $javascript_loop = 0, $timeout = 5 ) {
    $url = str_replace( "&amp;", "&", urldecode(trim($url)) );

    $cookie = tempnam ("/tmp", "CURLCOOKIE");
    $ch = curl_init();
    curl_setopt( $ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; rv:1.7.3) Gecko/20041001 Firefox/0.10.1" );
    curl_setopt( $ch, CURLOPT_URL, $url );
    curl_setopt( $ch, CURLOPT_COOKIEJAR, $cookie );
    curl_setopt( $ch, CURLOPT_FOLLOWLOCATION, true );
    curl_setopt( $ch, CURLOPT_ENCODING, "" );
    curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );
    curl_setopt( $ch, CURLOPT_AUTOREFERER, true );
    curl_setopt( $ch, CURLOPT_SSL_VERIFYPEER, false );    # required for https urls
    curl_setopt( $ch, CURLOPT_CONNECTTIMEOUT, $timeout );
    curl_setopt( $ch, CURLOPT_TIMEOUT, $timeout );
    curl_setopt( $ch, CURLOPT_MAXREDIRS, 10 );
    $content = curl_exec( $ch );
    $response = curl_getinfo( $ch );
    curl_close ( $ch );

    if ($response['http_code'] == 301 || $response['http_code'] == 302) {
        ini_set("user_agent", "Mozilla/5.0 (Windows; U; Windows NT 5.1; rv:1.7.3) Gecko/20041001 Firefox/0.10.1");

        if ( $headers = get_headers($response['url']) ) {
            foreach( $headers as $value ) {
                if ( substr( strtolower($value), 0, 9 ) == "location:" )
                    return get_url( trim( substr( $value, 9, strlen($value) ) ) );
            }
        }
    }

    if (    ( preg_match("/>[[:space:]]+window\.location\.replace\('(.*)'\)/i", $content, $value) || preg_match("/>[[:space:]]+window\.location\=\"(.*)\"/i", $content, $value) ) && $javascript_loop < 5) {
        return get_url( $value[1], $javascript_loop+1 );
    } else {
        return array( $content, $response );
    }
}

?>

然后我使用另一个文件用HTML DOM Parser读取这个文件，但我找不到正确的字符串来读取。有什么更好的方法呢？

从名为StackTraceElement[] trace = Thread.currentThread().getStackTrace(); System.out.println("[AspectJ]LineNumber: " + trace[trace.length-1].getLineNumber());的特殊Shoutcast页面请求当前曲目标题要容易得多：

7.html

用逗号分割数据，你将得到听众的数量，比特率和当前的曲目标题
