javascript - YouTube 查询功能不适用于我的 js bot 不和谐

问题描述

我需要有关此查询部分的帮助

client.on('message', (message) => {
 if (!message.content.startsWith(prefix) || message.author.bot) return;

 const args = message.content.slice(prefix.length).split(/ +/);
 const command = args.shift().toLowerCase();
 const query = command.slice(command.search(' '), command.search('-'));
 if (command === 'ping') {
  message.channel.send('pong!');
 } else if (command === 'joke') {
  message.channel.send('Your life');
 } else if (command === 'youtube') {
  message.channel.send('https://www.youtube.com/results?search_query=' + query);
  message.channel.send(query);
 } else if (command === 'commands') {
  message.channel.send('commands so far are +ping, +joke, +youtube, +commands');
 }
});

错误是这样的

(node:15016) UnhandledPromiseRejectionWarning: DiscordAPIError: Cannot send an empty message
    at RequestHandler.execute (C:\Users\kalar\Desktop\JavaPr\JS_Bot\node_modules\discord.js\src\rest\RequestHandler.js:170:25)

我在更改之前就这样做了，我只会发送 YouTube 链接而不是我正在尝试进行的查询。

else if (command === 'youtube') {
  message.channel.send('https://www.youtube.com/results?search_query=' + query);

解决方案

问题出在你的query变量上。

// this is overly complicated and will not work:
const query = command.slice(command.search(' '), command.search('-'));

// instead:
const query = args.join(' ');

此外，在这一行：

message.channel.send('https://www.youtube.com/results?search_query=' + query);

您应该使用该encodeURI()功能。

message.channel.send(
 encodeURI(`https://www.youtube.com/results?search_query=${query}`)
);
