Question

我正在为服务器制作机器人，并且之前已经做过，但是现在我收到一条错误消息，提示未定义receiveMessage。

这是代码，它将检查消息是否以“>”开头并检查它是什么命令（我知道switch语句更有效。）：

client.on('message', (receivedMessage) => {
    if (receivedMessage.content.startsWith(">")) {
        processCommand(receivedMessage)
    }
})

function processCommand(receivedMessage) {
let fullCommand = receivedMessage.content.substr(1)
let splitCommand = fullCommand.split(" ")
let primaryCommand = splitCommand[0]
let arguments = splitCommand.slice(1)

if (primaryCommand == "help") {
    helpCommand(arguments, primaryCommand)
} else if (primaryCommand == "giveRole") {
    gvRoleCommand(arguments, primaryCommand)
} else if (primaryCommand == "duck") {
    duckCommand(arguments, primaryCommand)
} else if (primaryCommand == "kick") {
    kickCommand(arguments, primaryCommand)
} else if (primaryCommand == "ban") {
    banCommand(arguments, primaryCommand)
} else if (primaryCommand == "listCommandForMyRole") {
    listCommandForRole(arguments, primaryCommand)
} else if (primaryCommand == "stoppedLookingForTeam") {
    stopLookingForTeamCommand(arguments, primaryCommand)
} else if (primaryCommand == "poke") {
    pokeCommand(arguments, primaryCommand)
} else if (primaryCommand == "stop") {
    stopCommand(arguments, primaryCommand)
} else if (primaryCommand == "ping") {
    pongCommand(arguments, primaryCommand)
} else {
    receivedMessage.channel.send("Error: Invalid command!")
}

我为以前的机器人使用了相同的代码，并且运行良好，我尝试使用相同的节点模块，因为在制造机器人时无法安装它们。当我想返回消息时（或机器人将消息发送时），将发生错误。

return receivedMessage.channel.send("Pong!");

谢谢！

您可以尝试一下此代码吗？如果它不起作用，请给我您的错误代码（截图/完整粘贴粘贴）

client.on("message", async message => {
    if (message.author.bot) return;

    if (message.content && message.content.startsWith('>')) {
        processCommand(message);
    }
})

function processCommand(message) {
    if (!message) return;
    let fullCommand = receivedMessage.content.substr(1)
    let splitCommand = fullCommand.split(" ")
    let primaryCommand = splitCommand[0]
    let arguments = splitCommand.slice(1)

    switch (primaryCommand) {
        case 'help':
            helpCommand(arguments, message)
            break;
        case 'giveRole':
            gvRoleCommand(arguments, message)
            break;
        case 'duck':
            duckCommand(arguments, message)
            break;
        case 'kick':
            kickCommand(arguments, message)
            break;
        case 'ban':
            banCommand(arguments, message)
            break;
        case 'listCommandForMyRole':
            listCommandForRole(arguments, message)
            break;
        case 'stoppedLookingForTeam':
            stopLookingForTeamCommand(arguments, message)
            break;
        case 'poke':
            pokeCommand(arguments, message)
            break;
        case 'stop':
            stopCommand(arguments, message)
            break;
        case 'ping':
            pongCommand(arguments, message)
            break;
        default:
            message.channel.send("Error: Invalid command!")
            break;
    }
}

function pongCommand(arguments, message) {
    return message.channel.send('Pong!')
}

我认为出错的是，当您执行函数时，没有传递“ message”变量。试试看，看看是否有效
