PHP：Icecast现在正在播放脚本无法正常工作

[英]PHP: Icecast Now Playing Script is Not Working

 原文  2014-08-12 15:16:30  9   2    php/ icecast

问题描述

I am attempting to use the Icecast Now Playing PHP script from: https://code.google.com/p/icecast-now-playing-script/ 我正尝试从以下网址使用“ Icecast Now Play PHP”脚本： https ： //code.google.com/p/icecast-now-playing-script/

I have uploaded all the files to my web server after modifying the config.php. 修改config.php后，我已将所有文件上传到Web服务器。 When I load example.php in the browser, this is the information returned: 当我在浏览器中加载example.php时，这是返回的信息： 

Array (
    [info] => Array
        (
            [status] => OFF AIR
        )

)

I am not sure what the cause of the problem is. 我不确定是什么原因造成的。 I have verified the Icecast server information is correct. 我已验证Icecast服务器信息正确。 Opening: http://70.35.120.203:8000/zedg_mb.mp3.m3u does start the stream playing. 开头：http: http://70.35.120.203:8000/zedg_mb.mp3.m3u : http://70.35.120.203:8000/zedg_mb.mp3.m3u确实开始播放流。 Here is the code: 这是代码：

I am quite new to PHP and am not understanding the instructions fully. 我对PHP还是很陌生，还没有完全理解这些说明。 Here are the instructions as posted: 以下是发布的说明：

How to use the script on your own site: 如何在自己的网站上使用脚本：

Get an API key from last.fm: http://www.last.fm/api/account Get the script, edit the config file (config.php) Use the available variables to echo what you want, there's also a list of available variables on this wiki page: code.google.com/p/icecast-now-playing-script/wiki/Variables Upload the scripts to your webspace which support PHP, Change the attribute of the script >directory to be writable("666" for example) 从last.fm获取一个API密钥： http : //www.last.fm/api/account获取脚本，编辑配置文件（config.php）使用可用变量来回显您想要的内容，还有一个列表此Wiki页面上的可用变量：code.google.com/p/icecast-now-playing-script/wiki/Variables将脚本上传到支持PHP的网站空间，将脚本>目录的属性更改为可写（“ 666 “ 例如）

UPDATE Using the advice of GView and removing the '@' in front of file_get_contents and calling var_dump($str) returns this error: 更新使用GView的建议并删除file_get_contents前面的'@'并调用var_dump（$ str）返回此错误：

Please note that I would strongly advice not using the "Icecast Now Playing Script"! 请注意，我强烈建议您不要使用“ Icecast Now Play Script”！
tl;dr : It parses the HTML, this is horrible. tl; dr ：它解析HTML，这太可怕了。

  1. The script uses regex to parse the Icecast status.xsl page, never ever should Regex be used to parse HTML, if you want to know why, read "Parsing Html The Cthulhu Way" . 该脚本使用regex来解析Icecast status.xsl页面，从不应该使用Regex来解析HTML，如果您想知道为什么，请阅读“解析Html Cthulhu Way” 。 It is very likely that it can break easily. 它很容易破裂。

  2. The script parses the Icecast status.xsl page. 该脚本解析Icecast status.xsl页面。 This should never ever be done, since this page is likely to change, like it did with the latest Icecast Version 2.4. 永远不要这样做，因为此页面可能会更改，就像最新的Icecast版本2.4一样。 So please, please, please do not parse the HTML page ! 因此，请，请不要解析HTML页面 ！

What to do instead? 该怎么做呢？

If this is your Icecast Server, you can easily write a custom xsl, to generate custom XML or JSON that contains the information that you need. 如果这是您的Icecast Server，则可以轻松编写自定义xsl，以生成包含所需信息的自定义XML或JSON。 (more info here ) （更多信息在这里 ）

An example for this is the xml2json.xslt . xml2json.xslt就是一个例子。

My guess is that your server is not allowing HTTP stream wrappers. 我的猜测是您的服务器不允许使用HTTP流包装器。

In the icecast.php script the function getStreamInf() is being called and at the top it attempts to open the stream with: 在icecast.php脚本中，调用了getStreamInf（）函数，并在顶部尝试使用以下命令打开流： 

$str = @file_get_contents(SERVER.'/status.xsl?mount='.MOUNT);

To debug this, do 2 things. 若要调试此，请做两件事。 First remove the @ which suppresses error output on the file_get_contents call. 首先删除@，以禁止在file_get_contents调用中输出错误。 Then add temporary debugging output: 然后添加临时调试输出： 

$str = file_get_contents(SERVER.'/status.xsl?mount='.MOUNT);
var_dump($str);

If you get a security related error, rather than data back, then you need to look at your php.ini file for the server. 如果收到与安全相关的错误，而不是返回数据，则需要查看服务器的php.ini文件。 

allow_url_fopen = on

Needs to be set for file_get_contents to be able to open a url, as this script attempts to do. 需要设置file_get_contents才能打开该脚本尝试执行的URL。 You have to be able to change that setting on your server, if it is set to off, and you have to be able to restart your web server for those changes to take effect. 如果已将其设置为关闭，则必须能够更改服务器上的该设置，并且必须能够重新启动Web服务器才能使这些更改生效。
