如何使用 content-disposition header 设置下载的 UTF-8 文件名？

Question

我正在将我的文件存储在 Amazon Cloud Drive 上。并且有选项可以设置 response-content-disposition 以直接从亚马逊发送 link。

来自API：

response-content-disposition: (Optional) If specified, the content-disposition of the response will be set to this value

我需要设置它下载mp3文件。我不需要在浏览器上播放它。

我想设置下载的文件名：Эльбрус Джанмирзоев - Кавказская любовь.mp3

我尝试了很多方法...Urlencode...Urlencode + http 构建查询等...

但现在的结果是：Эльбрус+Джанмирзоев+-+Кавказская+любовь.mp3下载文件时

这是我的 php 代码：

<?php
    function file_generate_download_link($filename = false, $force = true)
    {
            $json['tempLink'] = 'https://content-na.drive.amazonaws.com/cdproxy/templink/iTwUqoQ3cJXOpj6T8SCDmKwtF37TAENiSLQzy7pTSbkFfJttb';
            $url = $json['tempLink'];
            if($force)
            {
                $data['download'] = 'true';
            }
            if($filename)
            {               
                $data['response-content-disposition'] = ' attachment; filename*=UTF-8\'\''.urlencode($filename).'';
            }
            if(isset($data)) {
                $data = http_build_query($data);
                $url .= '?' . $data;
            }
            return $url;

    }

    echo file_generate_download_link($filename = 'Эльбрус Джанмирзоев - Кавказская любовь.mp3');
?>

这个代码 returns 我这个 link:

https://content-na.drive.amazonaws.com/cdproxy/templink/iTwUqoQ3cJXOpj6T8SCDmKwtF37TAENiSLQzy7pTSbkFfJttb?download=true&response-content-disposition=+attachment%3B+filename%2A%3DUTF-8%27%27%25D0%25AD%25D0%25BB%25D1%258C%25D0%25B1%25D1%2580%25D1%2583%25D1%2581%2B%25D0%2594%25D0%25B6%25D0%25B0%25D0%25BD%25D0%25BC%25D0%25B8%25D1%2580%25D0%25B7%25D0%25BE%25D0%25B5%25D0%25B2%2B-%2B%25D0%259A%25D0%25B0%25D0%25B2%25D0%25BA%25D0%25B0%25D0%25B7%25D1%2581%25D0%25BA%25D0%25B0%25D1%258F%2B%25D0%25BB%25D1%258E%25D0%25B1%25D0%25BE%25D0%25B2%25D1%258C.mp3

如果我输入这个 link Chrome 用这个名字保存这个文件：

Эльбрус+Джанмирзоев+-+Кавказская+любовь.mp3

但我需要用这个名称直接保存文件:

Эльбрус Джанмирзоев - Кавказская любовь.mp3

我的错误在哪里？

明白了！我需要使用 rawurlencode 函数！

所以正确的代码是：

<?php
    function file_generate_download_link($filename = false, $force = true)
    {
            $json['tempLink'] = 'https://content-na.drive.amazonaws.com/cdproxy/templink/iTwUqoQ3cJXOpj6T8SCDmKwtF37TAENiSLQzy7pTSbkFfJttb';
            $url = $json['tempLink'];
            if($force)
            {
                $data['download'] = 'true';
            }
            if($filename)
            {               
                $data['response-content-disposition'] = ' attachment; filename*=UTF-8\'\''.rawurlencode($filename).'';
            }
            if(isset($data)) {
                $data = http_build_query($data);
                $url .= '?' . $data;
            }
            return $url;

    }

    echo file_generate_download_link($filename = 'Эльбрус Джанмирзоев - Кавказская любовь.mp3');
?>
