Question

从这段代码我得到错误/home/container/welcome.js:9 message.channel.send（消息） ^

类型错误：无法读取未定义的属性“发送”

  const channelId = "812458294085550121";
 bot.on("guildMemberAdd", (member) => {
    console.log(member);

    const message = [`Welcome <@${member.id}> to our server`]

    const channel = member.guild.channels.cache.get(channelId)
    message.channel.send(message)
  })
}```

Answer 1

您似乎遇到的问题是，找不到该频道。因此can not find property 'send' of undefined。

试试这个：

 const channelId = "812458294085550121";
 bot.on("guildMemberAdd", (member) => {
    console.log(member);

    const welcomeMessage = `Welcome <@${member.id}> to our server`;

    const channel =  client.channels.cache.get(channelId);
    channel.send(welcomeMessage);
  });
}

您在代码中定义了“消息”以接收通道，而将“消息”定义为要发送的消息而不是对象。此外，您将消息放入数组中，这有点令人困惑，因此您还需要做的是使用索引位置访问数组中的消息。这应该有效：

const channelId = "812458294085550121"; // Define the channel id
bot.on("guildMemberAdd", (member) => { // Event listener when someone joined a server
    console.log(member); // Sends the member object in the console

    const message = [`Welcome <@${member.id}> to our server`] // Message in an array

    const channel = member.guild.channels.cache.get(channelId) // Find the channel
    if(!channel) return console.log(`Channel doesn't exists`); // If the channel doesn't exists
    channel.send(message[0]); // Send the message in the channel
});
