as2 / flash :: 如何通过 PHP 强制下载文件
我尝试通过 PHP 强制下载文件，
$ctype="application/zip";
header("Content-Type: $ctype");
header("Content-Length: ".filesize($filepath));
header("Expires: 0");
header("Content-Transfer-Encoding: binary");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0"); //header("Cache-Control: public");
header("Pragma: public");
header("Content-Disposition: attachment; filename=".$filename);
// header("Location: $filepath"); // edited: removed
readfile($filepath);
但它不起作用。
使用 firebug 我可以看到更改后的标题信息，但没有出现保存文件对话框...
I try to force a file-download via PHP with
$ctype="application/zip";
header("Content-Type: $ctype");
header("Content-Length: ".filesize($filepath));
header("Expires: 0");
header("Content-Transfer-Encoding: binary");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0"); //header("Cache-Control: public");
header("Pragma: public");
header("Content-Disposition: attachment; filename=".$filename);
// header("Location: $filepath"); // edited: removed
readfile($filepath);
but it doesn't work.
with firebug I can see the changed header information but no save-file dialog appears...

您需要删除
Which 基本上将您重定向到特定路径而不是读取其内容。
You need to remove
Which is basically redirecting you to the path specific instead of reading it's contents.
sendAndLoad()将“吃掉”您的响应，并且不会导致下载，这在您尝试加载数据时很有用。但是，在您的情况下，您需要使用getURL()因为您希望浏览器处理响应，而不是 flash。sendAndLoad()will "eat" your response and not cause a download which is useful if you're trying to load data. However, in your case you need to usegetURL()since you want the browser to deal with the response, not flash.
