当人们加入我的服务器时，这个迎接他们的不和谐机器人不起作用？

Question

我试图向任何使用此机器人加入我的不和谐服务器的人发出欢迎消息，但当有人加入时，不会发生任何事情。我得到一个错误：引用错误：通道名称未定义在C：\用户\Vir\桌面\DiscBot\index.js:13： 71在Map.find（C：\用户\Vir\桌面\DiscBot\node_modules\discord.js\src\util\Collection.js:506： 11）在客户端。（C：\用户\Vir\桌面\DiscBot\index.js:13： 43）在Client.emit（events.js:223： 5）在公会。_addMember（C：\用户\Vir\桌面\DiscBot\node_modules\discord.js\src\结构\Guild.js:1298： 19）在GuildMemberaddHandler.handle（C：\用户\Vir\桌面\DiscBot\node_modules\discord.js\src\客户端\WebSocketPacketMdd.js:12： 13）在WebSocketPacketManager.handle（C：\用户\Vir\桌面\DiscBot\node_modules\discord.js\src\客户端\webSocketPacketManager.js:105： 65）在WebSocketConnection.on数据包（C：\用户\Vir\桌面\DiscBot\node_modules\discord.js\src\客户端\webSocketConnection.js:333： 35）在WebSocketConnection.on消息（C：\用户\Vir\桌面\DiscBot\node_modules\discord.js\src\Client\webSocketConnection. js： 296:17）在WebSocket. onMessage（C：\用户\Vir\Desktop\DiscBot\node_modules\ws\lib\event-Target. js： 120:16）PS C：\用户\Vir\Desktop\DiscBot

错误表明未定义channelname。我认为你应该使用频道。取而代之的是名字，只是一个简单的打字错误。

在OP的评论之后，我检查了文档，您必须访问cache属性才能获得频道列表，如下所示：

js prettyprint-override">bot.on('guildMemberAdd', member => {
    const channel = member.guild.channels.cache.find(channel => channel.name === "welcome");

    if(!channel) {
        return;
    }

    channel.send(`Welcome, ${member}, make sure to read the rules and verfiy.`) 
});

他们已经更改了它，所以您现在需要使用缓存。所以在这种情况下：

bot.on('guildMemberAdd', member =>{
    const channel = member.guild.channels.cache.find(channel => channel.name === "welcome");
    if(!channel) return;

    channel.send('Welcome, ${member}, make sure to read the rules and verfiy.') 
});

希望这有帮助！

这是我用于此的代码

      client.on("guildMemberAdd", (member) => {

    const channel = member.guild.channels.cache.get('CHANNEL_ID'); 
    channel.send(`**Hey ${member.user}, welcome to the server!\nMake sure to read the rules in <#CHANNEL_ID>**`); 
});
