Question

为什么我的机器人没有检测到前缀？我放d没关系！或克！或其他信件。我希望我的机器人只能使用前缀购买我不知道为什么我写的内容无关紧要。然后我使用：名称：help，别名：h，调用其他命令。如果我把 g!help 或 f!help 放在它不能工作的时候它会工作。

您的代码仅检查以确保命令存在，使用前缀的长度对字符串进行切片：(message.content.slice(this.config.prefix.length).split(' ')[0])
但它不会检查消息是否以前缀开头：(message.content.startsWith(this.config.prefix)).

只需在消息事件处理程序的开头添加条件

this.on("message", async (message) => {
    if (!message.content.startsWith(this.config.prefix)) return;
    const args = message.content.slice(this.config.prefix.length).trim().split(" ")[0];
    ...
});

为什么我的前缀在我的不和谐机器人上不起作用？
