Discord js通过broadcastEval发送消息

Question

我在谷歌上搜索了一下，但我找不到真正的答案，因为分片似乎不是一个非常流行的论点，那么我们来了。

我正在尝试在我的机器人中处理分片，但我遇到了问题。我有接受消息作为参数的自定义事件，我要疯了让它们与 broadcastEval 一起工作

我已经尝试过 ${message} 并且没有工作，因为它只序列化文本并且我想要对象

我已经尝试过 JSON.stringify，但由于同样的原因也无法正常工作

我有点卡住了。我正在使用 Discord JS

这是调用函数

  function test2(_guild_id, _args, _message, gameInfo, _originalMessage, reaction_id){

   let msg = JSON.stringify(_message);
   let cmd = "command";
   let args = "args";
   let rights = 0;

   let stringToEval = `
   this.emit("SHARE_DATA", "${_message}", {
     guild_id: ${_guild_id},
     cmd: ${cmd},
     args: ${args},
     rights: ${rights}
   });
   `;
   log.debug(stringToEval);
/*
   // this is not working. I receive any sort of exceptions related to the fact
   // that it is serializing the text of the message only
   discordClient.shard.broadcastEval(stringToEval);
/*/
// this is working as intended
discordClient.emit("SHARE_DATA", _message, {
    guild_id: _guild_id,
    cmd: cmd,
    args: args,
    rights: rights
  });
//*/

}

这是听者

client.on("SHARE_DATA", (message, support) => {
  log.debug("Let's see if this shard id can be found .... it should be "+registered_shard_id);
  log.debug(`received message ${message} with support ${support}`);
  log.debug("we are on shard "+JSON.stringify(client.shard));
});

使用常规事件和像现在这样的单个分片应用程序，事件可以正确触发，完全没有问题，我只需添加 discordClient.emit 就可以了。 但是broadcastEval想要一个字符串，所以我需要序列化消息

编辑： 使用 msg variabe (JSON.stringified) 广播 eval 产生此错误

我最终使用了不同的方法 我实际上将序列化的对象保存在数据库中，只有数据，没有方法。

然后我只需发送 DB id，事件处理程序就会像这样重建消息

    message = new Discord.Message(discordClient, {
      id: msg.id,
      type: msg.type,
      content: msg.content,
      author: usr,
      pinned: msg.pinned,
      tts: msg.tts,
      embeds: msg.embeds,
      attachments: msg.attachments,
      nonce: "123" // idfk
  }, channel
  );

序列化只需通过

let serialMessage = JSON.stringify(message);

EDIT(TNX PLASMA Chicken)：另一个版本的解决方案：

let serialMessage = JSON.stringify(message);
// other code
message = new Discord.Message(discordClient, serialMessage, channel);
