目前我有一个插件每隔十秒就会将数据发布到一个URL，但在第一次（有时是第二次）之后，它会使用以下信息崩溃服务器：

这是我正在使用的方法：
public String postToURL(String url, List<NameValuePair> data) throws Exception {
HttpPost request = new HttpPost(url);
request.setHeader("key", key);
request.setEntity(new UrlEncodedFormEntity(data, Consts.UTF_8));
HttpResponse response = httpClient.execute(request);
java.util.Scanner s = new java.util.Scanner(response.getEntity().getContent(), "UTF-8").useDelimiter("\\A");
Bukkit.broadcastMessage(s.hasNext() + " - asfd");
return s.hasNext() ? s.next() : "";
}
触发该代码的代码（如果需要）：
new BukkitRunnable(){
@Override
public void run() {
PostResult result = null;
try {
result = gson.fromJson(postToURL("xxx", longRefresh), PostResult.class);
} catch (Exception e) {
e.printStackTrace();
longRefresh.clear();
}
if(result==null){
Bukkit.getConsoleSender().sendMessage(ChatColor.RED + "Unable to recieve information from the webserver (1)");
}
else if(result.success){
for(String cmd : result.commands){
cmd = cmd.contains("/") ? cmd.replace("/", "") : cmd;
Bukkit.dispatchCommand(Bukkit.getConsoleSender(), cmd);
Bukkit.getConsoleSender().sendMessage(ChatColor.GREEN + "Recieved reply from web: " + cmd);
}
}
else{
Bukkit.getConsoleSender().sendMessage(ChatColor.RED + "Unable to recieve information from the webserver (2)");
}
}
}.runTaskLaterAsynchronously(p, 1);
截取网址。
POST可以通过前两次，但在此之后它才会重新加载服务器。
任何帮助都会很棒， 添

F我不太了解http，但我知道你正在学习一些沮丧的做法。
将bukkit调度程序与Runnables一起使用而不是BukkitRunnables
Bukkit.getSchedular.scheduleSyncRepeatingTask(plugin, new Runnable(){}, 0L, 200L);
这段代码将帮助您安排在0秒后开始并每十秒重复一次的任务。您也可以通过一个小的更改让它以异步方式运行
Bukkit.getSchedular.scheduleAsyncRepeatingTask(plugin, new Runnable(){}, 0L, 200L);
运行它ASYNCHRONOUSLY将防止错误导致服务器崩溃，因为服务器和您的任务将在不同的线程上运行。
我还注意到你添加了一个
throws Exception;
确保您捕获所有这些异常并且不允许它们逃离服务器，因为它们也可能是原因。
