所以我正在制作一个java应用程序，它可以从特定的Spotify用户获取所有公共播放列表，这一切都很棒，直到我托盘并在基于linux的机器上运行我的项目（raspbian java version 1.8）它在Windows上我获得了预期的输出但是当在linux上运行时我得到了
来自linux的错误日志

这是包含getSpotifyPlayLists
的类
public class Spotify {
public static String clientId = ""; // inser client public key
public static String clientSecret = ""; // insert client sercet key
public static String userid = "";// inser user name
public Spotify(String clientId,String clientSecret,String userid) {
this.clientId = clientId;
this.clientSecret = clientSecret;
this.userid = userid;
}
public static Api api;
public static void GetPublicPlayLists() {
System.out.println
(new Exception().getStackTrace()[0].getMethodName());
ArrayList<String> data = new ArrayList<>();
api = Api.builder()
.clientId(clientId)
.clientSecret(clientSecret)
.build();
/* Create a request object. */
final ClientCredentialsGrantRequest request = api.clientCredentialsGrant().build();
/* Use the request object to make the request, either asynchronously (getAsync) or synchronously (get) */
final SettableFuture<ClientCredentials> responseFuture = request.getAsync();
/* Add callbacks to handle success and failure */
Futures.addCallback(responseFuture, new FutureCallback<ClientCredentials>() {
@Override
public void onSuccess(ClientCredentials clientCredentials) {
/* The tokens were retrieved successfully! */
System.out.println("Successfully retrieved an access token! " + clientCredentials.getAccessToken());
System.out.println("The access token expires in " + clientCredentials.getExpiresIn() + " seconds");
/* Set access token on the Api object so that it's used going forward */
api.setAccessToken(clientCredentials.getAccessToken());
/* Please note that this flow does not return a refresh token.
* That's only for the Authorization code flow */
final UserPlaylistsRequest request = api.getPlaylistsForUser(userid).build();
try {
final Page<SimplePlaylist> playlistsPage = request.get();
for (SimplePlaylist playlist : playlistsPage.getItems()) {
System.out.println(playlist.getName() + " : "+ playlist.getId() + " : "+ playlist.getUri() + " : track count ="+ playlist.getTracks().getTotal());
/* item i = new item();
i.title = playlist.getName();
i.creator = playlist.getOwner().getId();
i.uri = playlist.getId();
data.add(i);
*/
}
} catch (Exception e) {
System.out.println("Something went wrong!" + e.getMessage());
}
}
@Override
public void onFailure(Throwable throwable) {
/* An error occurred while getting the access token. This is probably caused by the client id or
* client secret is invalid. */
System.out.println("Something went wrong! 2" );
throwable.printStackTrace();
throwable.printStackTrace(System.out);
}
});
return;
}
}
spotify.spotifyhttpManger.execute类看起来像这样
private String execute(HttpMethod method) throws WebApiException, IOException {
final HttpClient httpClient = new HttpClient(connectionManager);
try {
httpClient.executeMethod(method);
handleErrorStatusCode(method);
String responseBody = method.getResponseBodyAsString();
handleErrorResponseBody(responseBody);
return responseBody;
} catch (IOException e) {
throw new IOException();
} finally {
method.releaseConnection();
}
}
我没有想法为什么我有这个错误，如何解决它的任何想法？
答案 0 :(得分：0)
所以我没有弄清楚问题是什么，但后来我重新安装操作系统又恢复了工作
