如何使用内容处置标头设置下载的UTF-8文件名

Question

我正在亚马逊云硬盘上存储我的文件。还有一个选项可以将response-content-disposition设置为直接从亚马逊链接。

来自API：

response-content-disposition：（可选）如果指定，响应的内容处理将设置为该值

我需要设置它下载mp3文件。我不需要在浏览器上播放。

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

我尝试了很多方法。。。URL代码。。。URL代码+http构建查询等…

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

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');
?>

这个代码返回给我这个链接：

https://content-na.drive.amazonaws.com/cdproxy/templink/iTwUqoQ3cJXOpj6T8SCDmKwtF37TAENiSLQzy7pTSbkFfJttb?download=true&响应内容处置=+附件%3B+文件名%2A%3DUF-8%27%27%25D0%25AD%25D0%25BB%25D1%258C%25D0%25B1%25D1%2580%25D1%2583%25D1%5581%2BD%25D0%2594%25D0%25B6%25DO%25B0%25DO25BD%25DO%25BC%25DO/25B8%25D1%25D0%25DO%25BE%25D0%25B5%25D0%25B2%2B-%2B%25D0%259A%25D0%25B0%25D0%25B2%25D0%25BA%25D0%25B0%25D0%25B7%25D1%2581%25D0%25BA%25DO%25B0%25D1%258F%2B%25DO%25BB%25D1%258E%25D0%25 B1%25D0%25BE%25D0%25B2%25D1%258C.mp3

如果我输入这个链接，Chrome会用这个名称保存这个文件：

Эльбрус+Джанмирзоев+-+Кавказская+любовь.mp3

但我需要保存这个名称的文件：

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');
?>
