我正在尝试将一个MP3文件上传到Laravel应用程序并遇到一个问题,即使该文件的属性设置为"audio/mpeg",它也会上传为"application/octet-stream"(.bin)文件.当我尝试死亡并将文件转储到服务器端代码时:

dd($request->file('file'));

我明白了:

UploadedFile {#187 ?
  -test: false
  -originalName: "CUS12309821-20-AUG-2016-13-48-13.mp3"
  -mimeType: "audio/mpeg"
  -size: 47000471
  -error: 0
  path: "/private/var/folders/c7/6ws0lxy95dd_lhz1k067_zkc0000gn/T"
  filename: "phpyZCsbU"
  basename: "phpyZCsbU"
  pathname: "/private/var/folders/c7/6ws0lxy95dd_lhz1k067_zkc0000gn/T/phpyZCsbU"
  extension: ""
  realPath: "/private/var/folders/c7/6ws0lxy95dd_lhz1k067_zkc0000gn/T/phpyZCsbU"

  cTime: 2016-09-20 12:56:00
  inode: 4565593
  size: 47000471
  perms: 0100600
  owner: 501
  group: 20
  type: "file"
  writable: true
  readable: true
  executable: false
  file: true
  dir: false
  link: false
}

看看我何时使用这种方法,确实说mimeType的文件属性是正确的"audio/mpeg"格式.但是当我上传文件后调用getMimeType()方法时,我得到:

"application/octet-stream"

这是路由方法中的代码:

/**
 * Store a newly created resource in storage.
 *
 * @param  \Illuminate\Http\Request  $request
 * …

我正在尝试使用PHP创建一个Web服务,以便与应用程序进行通信,从数据库获取数据并将其转换为应用程序的XML格式.但是,其中一列包含HTML,需要输出(我认为)作为CDATA.虽然我很难完成这个.请指教

<?php
mysql_connect(DB_HOST, DB_USER, DB_PASSWORD);
mysql_select_db(DB_NAME);

$sql = "SELECT post_date_gmt, post_content, post_title FROM [schema].wp_posts WHERE post_status = \"publish\" && post_type = \"post\" ORDER BY post_date_gmt DESC;";
$res = mysql_query($sql);

$xml = new XMLWriter();

$xml->openURI("php://output");
$xml->startDocument();
$xml->setIndent(true);

$xml->startElement('BlogPosts');

while ($row = mysql_fetch_assoc($res)) {

    $xml->startElement("Post");

    $xml->startElement("PostDate");
    $xml->writeRaw($row['post_date_gmt']);
    $xml->endElement();

    $xml->startElement("PostTitle");
    $xml->$writeRaw($row['post_title']);
    $xml->endElement();

    $xml->startCData("PostContent");
    $xml->writeCData($row['post_content']);
    $xml->endCData();

    $xml->endElement();

}

$xml->endElement();

header('Content-type: text/xml');
$xml->flush();

?>

非常感谢您提供的任何帮助!
