Undertow Core HTTPS 服务器给出 400 Bad Request

Question

我使用 io.undertow.core 设置了 Java HTTPS 服务器，创建了 HttpListener，看起来我的代码很完美，但是......它不起作用。它会根据任何请求给我 400 Bad Request。

下面是undertow、http等相关的代码：

package ru.epserv.epmodule.modules.serverapi;

import org.bukkit.Bukkit;
import org.json.simple.JSONObject;

import io.undertow.Undertow;
import io.undertow.server.HttpHandler;
import io.undertow.server.HttpServerExchange;
import ru.epserv.epmodule.modules.serverapi.contexts.BanwhyContext;
import ru.epserv.epmodule.modules.serverapi.contexts.FirstseenContext;
import ru.epserv.epmodule.modules.serverapi.contexts.GetPlayerContext;
import ru.epserv.epmodule.modules.serverapi.contexts.GetPlayersContext;
import ru.epserv.epmodule.modules.serverapi.contexts.GetWarningsContext;
import ru.epserv.epmodule.modules.serverapi.contexts.IsOnlineContext;
import ru.epserv.epmodule.modules.serverapi.contexts.LastseenContext;
import ru.epserv.epmodule.modules.serverapi.contexts.Ping;
import ru.epserv.epmodule.modules.serverapi.contexts.SendContext;
import ru.epserv.epmodule.modules.serverapi.contexts.SkillsContext;
import ru.epserv.epmodule.modules.serverapi.contexts.TimeplayedContext;
import ru.epserv.epmodule.modules.serverapi.contexts.UptimeContext;
import ru.epserv.epmodule.modules.serverapi.utils.ParsedRequest;

public class HTTPSServer {

    public static String notFound;
    public Undertow server;

    @SuppressWarnings("unchecked")
    public void start() {
        JSONObject notFoundJSON = new JSONObject();
        notFoundJSON.put("response", null);
        notFoundJSON.put("error", "not_found");

        HTTPSServer.notFound = notFoundJSON.toJSONString();

        Ping ping = new Ping();
        SendContext send = new SendContext();
        GetPlayersContext list = new GetPlayersContext();
        IsOnlineContext isOnline = new IsOnlineContext();
        UptimeContext uptime = new UptimeContext();
        FirstseenContext firstseen = new FirstseenContext();
        LastseenContext lastseen = new LastseenContext();
        TimeplayedContext timeplayed = new TimeplayedContext();
        BanwhyContext banwhy = new BanwhyContext();
        GetWarningsContext getWarnings = new GetWarningsContext();
        SkillsContext skills = new SkillsContext();
        GetPlayerContext getPlayer = new GetPlayerContext();

        this.server = Undertow.builder()
                .addHttpsListener(45105, "0.0.0.0", HTTPSServer.getSSLContextFromLetsEncrypt())
                .setHandler(new HttpHandler() {

                    @Override
                    public void handleRequest(final HttpServerExchange t) throws Exception {
                        ParsedRequest r = new ParsedRequest(t);
                        r.setResponseHeader("Access-Control-Allow-Origin", "*");
                        Bukkit.getLogger().warning(r.getRequestURI().getPath());
                        switch (r.getRequestURI().getPath().substring(1).trim()) {
                        case "ping":
                            ping.handle(r, t);
                            break;
                        case "send":
                            send.handle(r, t);
                            break;
                        case "list":
                            list.handle(r, t);
                            break;
                        case "isonline":
                            ServerAPI.log
                                    .warn("Отправлен запрос на устаревший адрес https://mc.epserv.ru:45105/isonline, "
                                            + "используйте isOnline. Адрес подключения: "
                                            + r.getRemoteAddress().toString() + ". User-Agent: "
                                            + r.getRequestHeaders().getFirst("User-Agent") + ".");
                            isOnline.handle(r, t);
                            break;
                        case "isOnline":
                            isOnline.handle(r, t);
                            break;
                        case "uptime":
                            uptime.handle(r, t);
                            break;
                        case "firstseen":
                            firstseen.handle(r, t);
                            break;
                        case "lastseen":
                            lastseen.handle(r, t);
                            break;
                        case "timeplayed":
                            timeplayed.handle(r, t);
                            break;
                        case "banwhy":
                            banwhy.handle(r, t);
                            break;
                        case "getWarnings":
                            getWarnings.handle(r, t);
                            break;
                        case "skills":
                            skills.handle(r, t);
                            break;
                        case "getPlayer":
                            getPlayer.handle(r, t);
                            break;
                        default:
                            r.setResponseCode(404);
                            r.write(HTTPSServer.notFound);
                            r.send();
                        }
                    }
                })
                .build();
        this.server.start();
    }

    public void stop() {
        server.stop();
    }

}

我还尝试使用 curl -v --data "" https://mc.epserv.ru:45105/list 获取更多信息，这是输出：

我尝试使用 AccessLogHandler、RequestDumpingHandler，但什么也没有，Undertow 没有记录任何内容并继续响应 400 Bad Request。

我做错了什么？我发现了一个错误还是什么？怎么了？ 如有需要请向我询问更多信息，如果我的英语不好请见谅

Answer 1

问题已解决 - 我再次使用 mvn install（来自 https://github.com/undertow-io/undertow 存储库）构建了 Undertow，现在它按预期工作了。这可能是 Undertow 2.1.2.Final-SNAPSHOT 的错误，但在 Undertow 2.1.4.Final-SNAPSHOT 上一切正常。
