在webroot之外嵌入flv和swf

Question

我有一個腳本可以在webroot之外上傳。通過網站我然後鏈接用戶的圖像文件等

因此，對於圖像的鏈接將是：

media.php?file=nameoffile.jpg&user=userid&folder=images 

這則用來顯示圖像：

<img src="media.php?file=nameoffile.jpg&user=userid&folder=images" width="100" border="0"> 

該作品罰款的圖像和提供鏈接下載文件。我使用ffmpeg將所有允許的視頻類型轉換爲flv（這些視頻經過測試，效果很好），但是當我嘗試嵌入flv視頻時，它永遠不會工作（它與直接該文件的鏈接只是不通過media.php）。如果可能的話，我還想嵌入.swf。

我使用jwplayer嵌入（工作原理與文件的直接鏈接只是沒有通過忽略原始）

      <embed

       id="player2" 
       name="player2" 
       src="player.swf" 
       width="328" 
       height="200" 
       allowscriptaccess="always" 
       allowfullscreen="true" 
       flashvars="file=media.php?file=nameoffile.flv&user=userid&folder=videos" 
      /> 
      </object> 
      <script type="text/javascript" src="jwplayer.js"></script> 
      <!-- END OF THE PLAYER EMBEDDING --> 

這裏是忽略原始

 $path_parts = pathinfo($_SERVER['REQUEST_URI']); 
     $file = basename(urldecode($_GET['file'])); 
     $user = basename(urldecode($_GET['user'])); 
     $folder = basename(urldecode($_GET['folder'])); 
     $ext = pathinfo($file, PATHINFO_EXTENSION); 

     $fileDir = 'pathoutsidewebroot'; 
     $filePath = $fileDir . $file; 

     switch(
     $ext) { 
      case "flv": $ctype="video/x-flv"; break; 
      // adobe 
      case "pdf": $ctype="application/pdf"; break; 
      // ms office 
      case "doc": $ctype="application/msword"; break; 
      case "rtf": $ctype="application/rtf"; break; 
      case "xls": $ctype="application/vnd.ms-excel"; break; 
      case "ppt": $ctype="application/vnd.ms-powerpoint"; break; 
      // open office 
      case "odt": $ctype="application/vnd.oasis.opendocument.text"; break; 
      case "ods": $ctype="application/vnd.oasis.opendocument.spreadsheet"; break; 
      default: $ctype = "application/force-download"; break; 
} 

     if(in_array($ext, $valid_formats_vid)){ 
      if (file_exists($filePath)) { 
       header('Content-Type: ' . mime_content_type($filePath)); 
       header('Content-Length: ' . filesize($filePath)); 
       readfile($filePath); 
     } 
     } 

     else if(in_array($ext, $valid_formats_img)) { 
      if (file_exists($filePath)) { 
       header('Content-Type: ' . mime_content_type($filePath)); 
       header('Content-Length: ' . filesize($filePath)); 
       readfile($filePath); 
      } 
     } 
     else if(in_array($ext, $valid_formats_docs)) { 
        if (file_exists($filePath)) 
        { 
      header("Pragma: public"); 
      header("Expires: 0"); 
      header("Cache-Control: must-revalidate, post-check=0, pre-check=0"); 
      header("Cache-Control: private",false); 
      header("Content-Type: $ctype"); 
      header("Content-Disposition: attachment; filename=\"".basename($filePath)."\";"); 
      header("Content-Transfer-Encoding: binary"); 
      header("Content-Length: ".@filesize($filePath)); 
      set_time_limit(0); 
      @readfile($filePath) or die("File not found.");     } 
     } 

頭from embed that is through media.php

Pragma:no-cache

X-Powered-By:PHP/5.3.6-13ubuntu3.8 

從直接的聯繫

頭到文件（正常工作的那個）

設法通過向忽略原始改變它這個（但仍然沒有工作）

  header("Content-Type: $ctype"); 
      header('Content-Length: ' . filesize($filePath)); 
      header('Accept-Ranges: bytes'); 
      $now = time(); 
      $then = gmstrftime("%a, %d %b %Y %H:%M:%S GMT", $now + 365*86440); 
      header("Expires: $then"); 
      ob_clean(); 
      flush(); 
      readfile($filePath);

Answer 1

我設法得到它與下面的工作，我還包括玩家拇指圖像（這是採取通過上傳的ffmpeg）：

header("Content-Type: $ctype"); 
header('Content-Length: ' . filesize($filePath)); 
header('Accept-Ranges: bytes'); 
$now = time(); 
$then = gmstrftime("%a, %d %b %Y %H:%M:%S GMT", $now + 365*86440); 
header("Expires: $then"); 
ob_clean(); 
flush(); 
readfile($filePath); 


$flv_path = 'media.php?file='.$row['cur_image'].'&folder=videos&user='.$row["posted_by"]; 

$thumb = pathinfo($row['cur_image']); 
$thumb_path = 'media.php?file='.$thumb['filename'].'.jpg&folder=videos&user='.$row["posted_by"]; 
?>   


<!-- START OF THE PLAYER EMBEDDING TO COPY-PASTE --> 
<div id="mediaplayer_<?php echo $row['p_id']; ?>">JW Player goes here</div>       
<script type="text/javascript"> 
         jwplayer("mediaplayer_<?php echo $row['p_id']; ?>").setup({ 
          flashplayer: "jwplayer/jwplayer.flash.swf", 
          file: "<?php echo $flv_path; ?>", 
          image: "<?php echo $thumb_path; ?>", 
          controlbar: "bottom", 
          width: "380", 
          height: "200", 
          primary: "flash", 
          type: "mp4", 
          controls: true, 
          allowscriptaccess: 'always' 
         }); 
</script> 
<!-- END OF THE PLAYER EMBEDDING --> 

Answer 2

問題在這裏：

flashvars="file=media.php?file=nameoffile.flv&user=userid&folder=videos" 

flashvars收到查詢st環，所以這被解釋爲

file : media.php?file=nameoffile.flv 
user : userid 
folder : videos 

您需要進行urlencode文件參數：

flashvars="file=media.php?file=nameoffile.flv&user=userid&folder=videos"

一個文件閱讀方法應該工作的，請查看以下鏈接：http://www.ibm.com/developerworks/library/os-php-readfiles/

改變你代碼，這一行：readfile（$ filePath）;與其他文件閱讀功能，我認爲流應該也與（PHP fread）

PHP手冊：fread：提供有用的信息，也請嘗試使用第一個用戶註釋。 http://php.net/manual/en/function.fread.php
