我的代码有问题。当我点击按钮下载图片时，它出现了我不知道的代码，如何解决这个问题？我的代码出了什么问题？
-->下载.php
if (isset($_GET['file']) && basename($_GET['file']) == $_GET['file']) {
$filename = $_GET['file'];
} else {
$filename = NULL;
}
// define error message
$err = '<p style="color:#990000">Sorry, the file you are requesting is unavailable.</p>';
if (!$filename) {
// if variable $filename is NULL or false display the message
echo $err;
} else {
// define the path to your download folder plus assign the file name
$path = '../images/upload/lowongan_pekerjaan/'.$filename;
// check that file exists and is readable
if (file_exists($path) && is_readable($path)) {
// get the file size and send the http headers
$size = filesize($path);
header('Content-Type: application/octet-stream');
header('Content-Length: '.$size);
header('Content-Disposition: attachment; filename='.$filename);
header('Content-Transfer-Encoding: binary');
// open the file in binary read-only mode
// display the error message if file can't be opened
$file = @fopen($path, 'rb');
if ($file) {
// stream the file and exit the script when complete
fpassthru($file);
exit;
} else {
echo $err;
}
} else {
echo $err;
}
}
为什么要这样表演？我的图片
我的代码出了什么问题？
header('Content-Type: application/octet-stream');
header('Content-Length: '.$size);
header('Content-Disposition: attachment; filename='.$filename);
header('Content-Transfer-Encoding: binary');
应该是
header('Content-Type: image/jpg');
header('Content-Length: '.$size);
header('Content-Disposition: attachment; filename='.$filename);
或png或gif或任何您的文件类型。浏览器不知道如何处理您发送的内容，因为application/octet流！=图像类型。
