我正在尝试让 Plupload 的 html4 运行时与 S3 一起使用。不幸的是，我在这里找到的示例必须是一个非常旧的 plupload 版本或没有正确记录，并且没有实时工作示例或源代码下载。
所以我将我的 Plupload/Flash 运行时的工作版本带到 S3 并简单地将 html4 运行时而不是 flash 并添加'success_action_redirect': （我从 plupload 论坛了解到，plupload 需要这样做才能知道文件上传何时完成）。我发现它确实有效，但有些脚本确实失败了。
这是我的源代码...
PHP：
<?php
$bucket = 'MyBucket';
$accessKeyId = 'MyKey';
$secret = 'MySecret';
// Policy Setup
if (!function_exists('hash_hmac')) : function hash_hmac($algo, $data, $key, $raw_output = false){
$blocksize = 64;
if (strlen($key) > $blocksize)
$key = pack('H*', $algo($key));
$key = str_pad($key, $blocksize, chr(0x00));
$ipad = str_repeat(chr(0x36), $blocksize);
$opad = str_repeat(chr(0x5c), $blocksize);
$hmac = pack('H*', $algo(($key^$opad) . pack('H*', $algo(($key^$ipad) . $data))));
return $raw_output ? $hmac : bin2hex($hmac);
}
endif;
// prepare policy
$policy = base64_encode(json_encode(array(
'expiration' => date('Y-m-d\TH:i:s.000\Z', strtotime('+1 day')),
'conditions' => array(
array('bucket' => $bucket),
array('acl' => 'authenticated-read'),
array('success_action_redirect' => 'http://mydomain.com/ThisCanBeAnyPage.php'),
array('starts-with', '$key', ''),
array('success_action_status' => '201'),
array('starts-with', '$name', ''),
array('starts-with', '$Filename', ''),
)
)));
// Sign Policy
$signature = base64_encode(hash_hmac('sha1', $policy, $secret, true));
?>

HTML：
<h3>Custom example</h3>
<div id="container">
<div id="filelist">No runtime found.</div>
<br />
<a id="pickfiles" href="#">[Select files]</a>
<a id="uploadfiles" href="#">[Upload files]</a>
</div>
所以总而言之，这个脚本确实有效，但缺少 file.size 并且根据我能够找到的内容没有进度指示。我想知道那里是否有一个 plupload html4 脚本，其中包含这里缺少的东西。我有一个尚未测试的解决方法。但我会保持更新。
