Question

我有两个代码块。它们共同协作从我的AWS S3 Container存储桶中列出和播放MP3文件。但我无法弄清楚＆＃34;专辑封面＆＃34; （即海报）。 KEEP IN MIND，每个相册文件夹包含一个海报图像，该图像与具有jpg扩展名的文件夹同名。例如，见下文：文件夹名称：Beatles-Greatest-Hits 文件夹内容： song01.mp3 song02.mp3 song03.mp3 甲壳虫最大-Hits.jpg

这个块工作正常连接到桶：我意识到它很长，但我正在尝试找到海报的路径，所以我把它包括在内。

以下是格式化jplayer代码的代码。我想要获得＆＃34;海报＆＃34;路径。如果我弄错了，那么它会正确显示......

bucket.listObjects(
    {
        MaxKeys: AWS_MaxKeys, 
        Prefix : '<?php echo $_REQUEST['p']; ?>', 
        Delimiter : '/' 
    },
    function (err, data) 
    {           
        if(data.Contents.length)
        {
            var prefix = '<?php echo $_REQUEST['p']; ?>';
            for(var countAws=1; countAws < data.Contents.length; countAws++)
            {                               
                var key = data.Contents[countAws].Key;
                var fileName = key.replace(prefix, '');
                var linkAws = getObject(key);
                var newlinkAws = linkAws.split('?');
                var links = newlinkAws[0];
                console.log(links);

                myPlaylist.add({
                    title:""+fileName+"",
                    artist:"Artist",
                    mp3:links,
                    oga:links,
                    poster: ""+currentFolder+"".jpg //<--- HERE IS THE ISSUE
                });                     
            }
        }
    }
)

*******代码＆＃34;海报：＆＃34;＆＃34; + currentFolder +＆＃34;＆＃34; .jpg＆＃34;以上就是问题所在。

上面给出的示例的绝对链接是： AWSS3 / musicpax / mpx_music /甲壳虫最大-点击/甲壳虫最大-Hits.jpg

但由于这是动态的，我不能使用绝对链接。您能否从顶部的代码中提供任何见解 - 这将导致正确的路径配置。

提前感谢您的帮助。

Answer 1

这会从链接（路径）中删除该名称...其中显示的是＆＃39; HERE＆＃39;

for(var countAws=1; countAws < data.Contents.length; countAws++)
            {                               
                var key = data.Contents[countAws].Key;
                var fileName = key.replace(prefix, '');
                var linkAws = getObject(key);
                var newlinkAws = linkAws.split('?');
                var links = newlinkAws[0];

                /* Gets Album name HERE */
                var album = links;
                album = album.split("/");
                album_name = (album[4]);

                console.log(links);

                myPlaylist.add({
                    title:""+fileName+"",
                    artist:""+album_name+"",
                    mp3:links,
                    oga:links,
                    poster: " "
                });                     
            }

使用jPlayer到AWS桶0的Javascript路径？
