java - Linux 特定错误 IOException

Question

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(public)播放列表，一切都很好，并且可以正常工作，直到我在基于 linux 的机器(raspbian java 版本 1.8)上运行我的项目时Windows 我得到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();
    }
  }

我不知道为什么会出现此错误或如何在 atm 上解决它？

Answer 1

所以我没能弄清楚问题出在哪里，但后来我重新安装了操作系统，它又能正常工作了
