Discord Bot MessageDeleted 事件处理程序无法正常工作
Discord Bot MessageDeleted event handler not working correctly
我想制作一个记录已删除消息的 discord 机器人。
所以我制作了 MessageDeleted 事件处理程序,但它无法正常工作。
我找不到我的代码有什么问题。
private async Task Client_MessageDeleted(Cacheable<IMessage, ulong> arg1, ISocketMessageChannel channel)
{
Task<IMessage> msg = arg1.GetOrDownloadAsync();
EmbedBuilder embed = new EmbedBuilder();
embed.WithColor(40, 200, 150);
embed.AddField("deleted message", msg.ToString());
await channel.SendMessageAsync("", false, embed.Build());
}
替换
embed.AddField("deleted message", msg.ToString());
与
embed.AddField("deleted message", msg.Content);
我之前没有开发过 Discord Bot,所以请原谅我的无知,但我假设是这样的:
Task<IMessage> msg = arg1.GetOrDownloadAsync();
实际上应该是:
IMessage msg = await arg1.GetOrDownloadAsync();
正如其他人所指出的,您必须等待您的任务。但是,您缺少一项关键配置 - 启用消息缓存。对于 Discord.Net 和 MessageDeleted 事件,为了检索消息,您必须启用缓存,因为您无法从 Discord 服务器检索已删除的消息。要启用缓存,请在 DiscordSocketConfig
对象中设置 MessageCacheSize
并将其传递给 DiscordSocketClient
。
设置缓存
var config = new DiscordSocketConfig {MessageCacheSize = 100};
var client = new DiscordSocketClient(config);
正在从缓存中获取已删除的消息
private Task OnMessageDeleted(Cacheable<IMessage, ulong> msg, ISocketMessageChannel channel)
{
Console.WriteLine(msg.HasValue ?
msg.Value.Content :
"A message was deleted, but its content could not be retrieved from cache.");
return Task.CompletedTask;
}
此事件在 Discord.Net 文档中有详细记录,请参阅 MessageDeleted event。
