如何根据通过提示从用户输入收集的输入进行自定义嵌入 - Discord.js

Question

我正在尝试发出建议命令，如果用户在服务器中键入 =suggest，它将在他们的 DM 中创建一个提示，要求提供不同的规范。

但是，我不确定如何获取用户输入并在嵌入中使用该输入。我该怎么做？

例如： 机器人会在 DM 的 中询问“你希望标题是什么？”，然后用户会用他们想要的标题进行响应，并将该输入设置为标题。

您可以使用消息收集器。我在这里使用channel.awaitMessages：

const prefix = '!';

client.on('message', (message) => {
  if (message.author.bot || !message.content.startsWith(prefix)) return;
  const args = message.content.slice(prefix.length).split(/ +/);
  const command = args.shift().toLowerCase();

  if (command === 'suggest') {
    // send the question
    message.channel.send('What would you like the title to be?');

    // use a filter to only collect a response from the message author
    const filter = (response) => response.author.id === message.author.id;
    // only accept a maximum of one message, and error after one minute
    const options = { max: 1, time: 60000, errors: ['time'] };

    message.channel
      .awaitMessages(filter, options)
      .then((collected) => {
        // the first collected message's content will be the title
        const title = collected.first().content;
        const embed = new MessageEmbed()
          .setTitle(title)
          .setDescription('This embed has a custom title');

        message.channel.send(embed);
      })
      .catch((collected) =>
        console.log(`After a minute, only collected ${collected.size} messages.`),
      );
  }
});

我刚刚注意到您想通过 DM 发送它。在这种情况下，你可以.send()第一条消息，等待它被解析，这样你就可以使用channel.createMessageCollector()在频道中添加一个消息收集器。我添加了一些 cmets 来解释它：

const prefix = '!';

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

  const args = message.content.slice(prefix.length).split(/ +/);
  const command = args.shift().toLowerCase();
  const MINUTES = 5;

  if (command === 'suggest') {
    const questions = [
      { answer: null, field: 'title' },
      { answer: null, field: 'description' },
      { answer: null, field: 'author name' },
      { answer: null, field: 'colour' },
    ];
    let current = 0;

    // wait for the message to be sent and grab the returned message
    // so we can add the message collector
    const sent = await message.author.send(
      `**Question 1 of ${questions.length}:**\nWhat would you like the ${questions[current].field} be?`,
    );

    const filter = (response) => response.author.id === message.author.id;
    // send in the DM channel where the original question was sent
    const collector = sent.channel.createMessageCollector(filter, {
      max: questions.length,
      time: MINUTES * 60 * 1000,
    });

    // fires every time a message is collected
    collector.on('collect', (message) => {
      // add the answer and increase the current index
      questions[current++].answer = message.content;
      const hasMoreQuestions = current < questions.length;

      if (hasMoreQuestions) {
        message.author.send(
          `**Question ${current + 1} of ${questions.length}:**\nWhat would you like the ${questions[current].field} be?`,
        );
      }
    });

    // fires when either times out or when reached the limit
    collector.on('end', (collected, reason) => {
      if (reason === 'time') {
        return message.author.send(
          `I'm not saying you're slow but you only answered ${collected.size} questions out of ${questions.length} in ${MINUTES} minutes. I gave up.`,
        );
      }

      const embed = new MessageEmbed()
        .setTitle(questions[0].answer)
        .setDescription(questions[1].answer)
        .setAuthor(questions[2].answer)
        .setColor(questions[3].answer);

      message.author.send('Here is your embed:');
      message.author.send(embed);
      // send a message for confirmation
      message.author.send('Would you like it to be published? `y[es]/n[o]`');
      message.author.dmChannel
        .awaitMessages(
          // set up a filter to only accept y, yes, n, and no
          (m) => ['y', 'yes', 'n', 'no'].includes(m.content.toLowerCase()),
          { max: 1 },
        )
        .then((coll) => {
          let response = coll.first().content.toLowerCase();
          if (['y', 'yes'].includes(response)) {
            // publish embed, like send in a channel, etc
            // then let the member know that you've finished
            message.author.send('Great, the embed is published.');
          } else {
            // nothing else to do really, just let them know what happened
            message.author.send('Publishing the embed is cancelled.');
          }
        })
        .catch((coll) => console.log('handle error'));
    });
  }
});
