Answer 1

是否在 php 中构建了正确的表单了呢？

<?php
  $bucket = 'youbucket'; /// 空间名
  $form_api_secret = 'yourapisecret';
  $options = array();
  $options['bucket'] = $bucket; /// 空间名
  $options['expiration'] = time()+600; /// 授权过期时间
  $options['save-key'] = '/{filename}{.suffix}';
  $policy = base64_encode(json_encode($options));
  $sign = md5($policy.'&'.$form_api_secret); 
?>


<form action="http://v0.api.upyun.com/<?php echo $bucket?>/" method="post"      enctype="Multipart/form-data">
    <input type="hidden" name="policy" value="<?php echo $policy?>">
    <input type="hidden" name="signature" value="<?php echo $sign?>">
    <input type="file" name="file">
    <input type="submit">
</form>
