嘿,我想为喜欢最近的曲目构建一个简单的 android 应用程序。我使用 user.getRecentTrack 接收歌曲并将数据和会话密钥发送到我的方法,但出现错误:“目标服务器无法响应。” 有时,lastfm 方法也会出现错误 3:track.love:“Invalid Method - No method with that name in this package”。这是我对track.love的 Http 发布请求
HttpClient client = new DefaultHttpClient();
String postURL = "http://ws.audioscrobbler.com/2.0/";;
HttpPost post = new HttpPost(postURL);
List<NameValuePair> params = new ArrayList<NameValuePair>(2);
String signatur = makeTrackLoveSignatur(artist, title, key);
params.add(new BasicNameValuePair("method", "track.love"));
params.add(new BasicNameValuePair("track", title));
params.add(new BasicNameValuePair("artist", artist));
params.add(new BasicNameValuePair("api_key", api_key));
params.add(new BasicNameValuePair("api_sig", signatur));
params.add(new BasicNameValuePair("sk", key));
params.add(new BasicNameValuePair("format", "json"));
UrlEncodedFormEntity ent =
new UrlEncodedFormEntity(params,HTTP.UTF_8);
post.setEntity(ent);
HttpResponse responsePOST = client.execute(post);
InputStream data = responsePOST.getEntity().getContent();
我还实现了一个将 InputStream 转换为 String 的方法:
BufferedReader reader = new BufferedReader(
new InputStreamReader(stream));
StringBuilder sb = new StringBuilder();
String line = null;
try {
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
stream.close();
} catch (IOException e) {
e.printStackTrace();
}
System.out.println("Output"+sb.toString());
return sb.toString();
有什么问题?谢谢...
