为什么不用outpre呢？

[ksqeib]

无法复现，需要更详细的复现流程
我使用floodgate登入后再通过离线加入无法复现

你的目标

• 无论outpre还是backend,同名离线玩家在基岩版玩家在线时被阻止登录

当前环境

• velocity-3.5.0-SNAPSHOT-605(已正确配置player-info-forwarding-mode = "modern"与secret)
• paper-26.1.2-72
• Nanolimbo最新
• 安装模块：auth-floodgate,auth-yggd,auth-offline,safe
• SQLITE

插件版本与下载渠道

• HyperZoneLogin-26.7.2-SNAPSHOT-f4dfd224-all(QQ 群)

服务器插件列表

Velocity:

• HyperZoneLogin,Geyser-Velocity,floodgate-velocity

Paper:

• floodgate-spigot

具体问题

当基岩版玩家在线时，使用同名离线Java版玩家进入服务器，可以直接不登录顶掉基岩版玩家的连接（即“夺舍”）。该问题在backend模式和outpre模式下均可复现，且即使在outpre模式下，Paper端floodgate也会将Java版玩家识别为基岩版玩家。

复现步骤（本地最小环境测试）：

1. 环境搭建：

   • 关闭Paper端online_mode，Velocity保持online_mode=true，开启modern转发，复制secret到Nanolimbo和Paper。
   • 在Velocity安装Geyser和Floodgate，在Paper安装floodgate-spigot，启动一次后开启floodgate数据转发并将Paper端生成的key.pem复制到Velocity。
   • 安装HyperZoneLogin。

2. 配置（首次测试使用backend模式）：

   • HyperZoneLogin配置（仅列出修改部分）：

     v-server {
         mode=backend
         post-auth-default-server=lobby
         remember-requested-server-during-auth=true
         backend {
             fallback-auth-server=limbo
             enable-player-info-compensation=true
             enable-profile-compensation=true
             enable-name-hot-change=true
             enable-uuid-hot-change=false
         }
     }

 其余保持默认。

• Velocity配置：

     [servers]
     limbo = "127.0.0.1:18156"
     lobby = "127.0.0.1:18157"
     try = ["lobby"]   # 也测试过将lobby换成limbo，复现结果相同

3. 复现操作：

   • 先使用基岩版（最新版）登录，等待其通过验证进入Paper服（lobby）。
   • 立即使用同名Xbox档案的离线Java版（使用PCL启动器，也测试过其他启动器）进入服务器。
   • 观察到基岩版玩家被踢出（提示“你已在异地登录”），Java版玩家直接进入游戏，且拥有基岩版玩家的存档和权限。

4. 日志（Velocity端）：

5. Paper端对应日志：

   [12:38:26 INFO]: UUID of player emuyx is 00000000-0000-0000-0009-01f8479aaef5
   [12:38:26 INFO]: [floodgate] Floodgate 玩家 .emuyx 已断开连接

   [12:38:54 INFO]: emuyx lost connection: Disconnected
   [12:38:54 INFO]: emuyx left the game

6. 在backend模式下，删库（hyperzonelogin/data）后重复上述步骤5次，每次均成功夺舍。

7. 切换至outpre模式测试：

   • 修改HyperZoneLogin配置：

     v-server {
         mode=outpre
         post-auth-default-server=lobby
         remember-requested-server-during-auth=true
         outpre {
             auth-label=outpre-auth
             auth-host="127.0.0.1"
             auth-port=18156
             presented-host=""
             presented-port=-1
             presented-player-ip=""
         }
     }

• 修改Velocity配置，移除limbo服务器，仅保留lobby，try = ["lobby"]。
• 删库后重复相同操作：基岩版先登录，然后同名离线Java版进入。
• 结果相同：基岩版被踢，Java版成功进入（Velocity日志）：

     [12:44:39 INFO] [hyperzonelogin]: 传入 UUID 信息玩家: emuyx UUID:00000000-0000-3005-998f-50309ab05476 类型: PCL 在线:false
     [12:44:39 INFO]: [connected player] emuyx (/127.0.0.1:56477) entered outpre pre-registration flow
     [12:44:39 INFO] [hyperzonelogin]: [LoginProfileReplace] 替换成功: server=outpre-auth name=emuyx uuid=00000000-0000-0000-0009-01f8479aaef5
     [12:44:39 INFO]: [server connection] emuyx -> outpre-auth has connected
     [12:44:39 INFO]: [server connection] emuyx -> outpre-auth has disconnected
     [12:44:39 INFO]: [server connection] emuyx -> lobby has connected
     [12:44:41 INFO]: [connected player] emuyx (/127.0.0.1:0): kicked from server lobby: multiplayer.disconnect.duplicate_login
     [12:44:41 INFO]: [server connection] emuyx -> lobby has disconnected
     [12:44:41 INFO]: [connected player] emuyx (/127.0.0.1:0) has disconnected: 您已被踢出 lobby：multiplayer.disconnect.duplicate_login
     [12:44:41 INFO] [floodgate]: Floodgate 玩家 emuyx 已断开连接
     [12:44:41 INFO] [geyser]: emuyx 已因 §r§c您已被踢出 lobby：你已在异地登录 与 Java 服务器断开了连接

• 此时Paper端日志显示floodgate将Java玩家识别为基岩版：

     [12:44:41 INFO]: UUID of player emuyx is 00000000-0000-0000-0009-01f8479aaef5
     [12:44:41 INFO]: emuyx lost connection: You logged in from another location
     [12:44:41 INFO]: emuyx left the game
     [12:44:41 INFO]: [floodgate] Floodgate 玩家 .emuyx 加入了 (UUID: 00000000-0000-0000-0009-01f8479aaef5)
     [12:44:41 INFO]: emuyx joined the game
     [12:44:41 INFO]: emuyx[/127.0.0.1:56481] logged in with entity id 529 at ([minecraft:overworld]-127.61579, 91.0, 55.319935)

• 同样重复5次删库测试，均成功复现。

8. 额外验证：使用另一个微软账户登录基岩版，重复上述步骤，每次均成功复现夺舍问题。
