我尝试使用提供的API Mojang通过网站从UUID中检索名称。
这是我使用的代码(我验证它有效):
@Override
public Map<UUID, String> call() throws Exception {
Map<UUID, String> uuidStringMap = new HashMap<UUID, String>();
for (UUID uuid : uuids) {
HttpURLConnection connection = (HttpURLConnection) new URL(
PROFILE_URL + uuid.toString().replace("-", ""))
.openConnection();
JSONObject response;
System.out.println("String: " + fromStream(connection.getInputStream()));
System.out.print("Line: " + uuid.toString());
String name = null;
try {
response = (JSONObject) jsonParser
.parse(new InputStreamReader(connection.getInputStream()));
name = (String) response.get("name");
if (name == null) {
continue;
}
String cause = (String) response.get("cause");
String errorMessage = (String) response.get("errorMessage");
if (cause != null && cause.length() > 0) {
throw new IllegalStateException(errorMessage);
}
} catch (Exception e) {
System.out.print("Could not parse uuid '" + uuid.toString() + "' to name!");
System.out.print("Trying Bukkit.getOfflinePlayer()");
OfflinePlayer oPlayer = Bukkit.getOfflinePlayer(uuid);
if (oPlayer != null && oPlayer.getFirstPlayed() != 0) {
name = oPlayer.getName();
System.out.print("Got player " + name);
} else {
System.out.print("Could not retrieve player with Bukkit.getOfflinePlayer()");
e.printStackTrace();
}
//throw new Exception("Could not parse uuid '" + uuid.toString() + "' to name!");
}
uuidStringMap.put(uuid, name);
}
return uuidStringMap;
}
不要介意所有System.out.print行,这只是调试内容。
错误导致此错误:

现在,我通过一些JSON在线解析器运行返回的json。他们都告诉我JSON是正确的。这是要返回的JSON:

我看到还有其他人有类似的问题,here。
该意外令牌可以在哪里?

在解析之前尝试将.toString()应用于输入字符串。
例如:
DataInputStream in = new DataInputStream(clientSocket.getInputStream());
String dataIn = in.readUTF();
JSONObject jobj = (JSONObject) parser.parse(dataIn.toString());
刚才为我工作过。 :d

在我的情况下,我试图解析空文件。所以,我在解析之前添加了简单的检查,问题就消失了。
