我正在使用声音云搜索 API。当我点击搜索网址时,它会给我搜索结果。每个音频都有流 url 但没有下载 url,因为它取决于上传者的设置。每个不可下载的文件也有超过 1 的下载计数。例如,当您点击此 url 时

http://api.soundcloud.com/tracks.json?client_id=4346c8125f4f5c40ad666bacd8e96498&q=tere%20bin&limit=1

它会给出这样的搜索结果

[{"kind":"track","id":63225776,"created_at":"2012/10/13 01:52:38 +0000","user_id":26029726,"duration":206177,"commentable":true,"state":"finished","original_content_size":3298521,"last_modified":"2014/10/01 18:56:25 +0000","sharing":"public","tag_list":"","permalink":"tere-bin-uzair-jaswal-official","streamable":true,"embeddable_by":"all","downloadable":false,"purchase_url":null,"label_id":null,"purchase_title":null,"genre":"Musical","title":"Tere Bin - Uzair Jaswal [Official Music Audio]","description":"","label_name":"","release":"","track_type":"original","key_signature":"","isrc":"","video_url":null,"bpm":null,"release_year":null,"release_month":null,"release_day":null,"original_format":"mp3","license":"all-rights-reserved","uri":"https://api.soundcloud.com/tracks/63225776","user":{"id":26029726,"kind":"user","permalink":"uzair-jaswal-1","username":"Uzair Jaswal Music","last_modified":"2014/10/19 13:06:28 +0000","uri":"https://api.soundcloud.com/users/26029726","permalink_url":"http://soundcloud.com/uzair-jaswal-1","avatar_url":"https://i1.sndcdn.com/avatars-000110064166-2ts508-large.jpg"},"permalink_url":"http://soundcloud.com/uzair-jaswal-1/tere-bin-uzair-jaswal-official","artwork_url":"https://i1.sndcdn.com/artworks-000032079002-kup6vc-large.jpg","waveform_url":"https://w1.sndcdn.com/9bwAsZfGrxwN_m.png","stream_url":"https://api.soundcloud.com/tracks/63225776/stream","playback_count":359588,"download_count":100,"favoritings_count":7557,"comment_count":491,"attachments_uri":"https://api.soundcloud.com/tracks/63225776/attachments","policy":"ALLOW"}]

这仅适用于一个音频,该音频不可下载,但下载次数为 100。这怎么可能?谁能告诉我如何下载不可下载的音频?任何帮助将非常感激。谢谢:)

最佳答案

我自己修复了它,我使用的是 android 并且流 url 也是一个下载 url。流 url 也是用于下载的下载 url,但不会影响下载次数。你可以这样试试

String file_url = "https://api.soundcloud.com/tracks/93216523/stream?client_id=4346c8125f4f5c40ad666bacd8e96498"; 

将此 url 传递给 asyntack 并管理你在那里下载,你可以这样传递它

new DownloadFileFromURL().execute(file_url);

这里是使用异步任务的 DownloadFileFromUR 类

class DownloadFileFromURL extends AsyncTask<String, Integer, String> {


@Override
protected void onPreExecute() {
super.onPreExecute();
}

@Override
protected String doInBackground(String... f_url) {
URL u = null;
InputStream is = null;

try {
u = new URL(f_url[0]);
is = u.openStream();
HttpURLConnection huc = (HttpURLConnection)u.openConnection();//to know the size of video
int size = huc.getContentLength();

if(huc != null){
String fileName = "FILE2.mp3";
String storagePath = Environment.getExternalStorageDirectory().toString();
File f = new File(storagePath,fileName);

FileOutputStream fos = new FileOutputStream(f);
byte[] buffer = new byte[1024];
long total = 0;
int len1 = 0;
if(is != null){
while ((len1 = is.read(buffer)) > 0) {
total+=len1;
publishProgress((int)((total*100)/size));
fos.write(buffer,0, len1);
}
}
if(fos != null){
fos.close();
}
}
}catch (MalformedURLException mue) {
mue.printStackTrace();
} catch (IOException ioe) {
ioe.printStackTrace();
} finally {
try {
if(is != null){
is.close();
}
}catch (IOException ioe) {
// just going to ignore this one
}
}
return "";
}


@Override
protected void onPostExecute(String file_url) {


}

}
