请教关于客户端升级程序的PHP脚本

ocptobe · 发表于 2004-9-28 22:55

返回文件的类型就是mime type类型，你可以参考相关文档。
比如GIF图片类型：header('Content-type: image/gif')
如果你要提供文件下载的话，用header('Content-type: application/octet-stream')类型。

改成这个样子了。
header('Content-type: application/octet-stream');
$url = "http://202.204.112.206/upgrade/test.php";
header("Location: $url"

;
可是还是提示
Warning: Cannot add header information - headers already sent by (output started at /var/www/html/upgrade/index.php:8) in /var/www/html/upgrade/index.php on line 12

<?php
if (($_GET['m_pszAppName']==Supplicant) && ($_GET['IDS_VERSION']!=1.0)) {
//以下是为客户端提供下载文件是示例，根据需要适当修改
$file = fopen($file_dir.$file_name,"r"

;
header('Content-type: application/octet-stream');
Header("Accept-Ranges: bytes"

;
   Header("Accept-Length: ".filesize($file_dir.$file_name));
   Header("Content-Disposition: attachment; filename=".$file_name);
   echo fread($file,filesize($file_dir.$file_name));
   fclose($file);

}
else {
      echo "UP TO DATE";
}
?>

header前不要有任何输出到浏览器

staryshine · 发表于 2004-9-30 09:00

header前没有任何输出到浏览器呀

if (($_GET['m_pszAppName']==Supplicant) && ($_GET['IDS_VERSION']!=1.0))
{
      $file_dir = "/var/www/html/upgrade/";
      $file_name = "uploadfile.txt";
      $file = fopen($file_dir.$file_name , "r"

;
Header('Content-type: application/octet-stream');
Header("Accept-Ranges: bytes"

;
                        Header("Accept-Length: ".filesize($file_dir.$file_name));
                        Header("Content-Disposition: attachment; filename=".$file_name);
                     echo fread($file,filesize($file_dir.$file_name));
                     fclose($file);

   }
                     else

   $url = "UP TO DATE";
echo $url;

我测试了一下，在我这边没有问题，注意最上面不要有空行和空格。
