我想做的事情:
我试图将jpg文件推送到用户看到URL下载。在这种情况下,文件位于:http://www.example.com/upload/asdasdsadpokdaspdso/36.jpg
。
我目前的代码:
header('Content-type: application/octet-stream');
header('Content-Disposition: attachment; filename="'.$download->name.'.jpg"');
readfile($weburl."/upload/".$hiddenpassage."/".$download->link);
我的vars / db值:
$weburl = "http://wwww.example.com";
$hiddenpassage = "asdasdsadpokdaspdso";
$download->link = 36.jpg //not a var, just drom db.
$download->name = The First Test Product //not a var, just from db.
问题:
当我下载时,我打开它,我收到以下错误:
The file “The First Test Product (28).jpg” could not be opened. It may be damaged or use a file format that Preview doesn’t recognize.
将.jpg重命名为.txt:
大部分内容都是我从中下载的页面内容。
答案 0 :(得分:0)
我认为你需要指定整个标题(未经测试)。特别是Content-Length。:
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename='.$download->name.'.jpg');
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($weburl."/upload/".$hiddenpassage."/".$download->link));
readfile($weburl."/upload/".$hiddenpassage."/".$download->link);
希望这有帮助。
