Question

我正在制作一个不和谐的机器人，我希望该机器人发送用户发送的表情符号的图像或gif，但我似乎无法弄清楚如何检测表情符号是否为动画。< / p>

        var emoji1 = args[0].split(':')
        var emojiID = emoji1[2].split('>')

        const emoji = bot.emojis.get(emojiID);

        if (emoji.animated == true) {
            message.channel.send({
                file: "https://cdn.discordapp.com/emojis/" + emojiID[0] + ".gif"
            });
        } else {
            message.channel.send({
                file: "https://cdn.discordapp.com/emojis/" + emojiID[0] + ".png"
            });
        }

但是当我运行它时我得到一个错误

Cannot read property 'animated' of undefined

Answer 1

您应该尝试做

const emoji = client.emojis.find(emoji => emoji.name === `${emoji1}`);```

Answer 2

我建议为此使用Regex。 Here是一个在线编辑器，可以帮助您构建正则表达式

    var emojiId = args.join(" ").match(/(?<=<a?:.*:)\d*(?=>)/);

    const emoji = bot.emojis.get(emojiID[0]);

    message.channel.send({
            file: "https://cdn.discordapp.com/emojis/" + emojiID[0] + emoji.animated
                    ? ".gif"
                    : ".png"
    });

Answer 3

  const emoji = args[0];
  if(!emoji) return message.reply('Please define emoji to search for.');
  const emojiID = emoji.replace(/[^0-9]+/g, ''); //Using RegEx remove everything that isn't a number.
  const fetch = bot.emojis.get(emojiID); //Grab the emoji
  if(fetch.animated == true){ //If it's aniamted.
    message.channel.send({file: `https://cdn.discordapp.com/emojis/${emojiID}.gif`});
  }else if(fetch.animated == false){ //If it isn't
    message.channel.send({file: `https://cdn.discordapp.com/emojis/${emojiID}.png`});
  }else{ //If emoji isn't found
    return message.reply('Emoji not found. :(')
  }

这是我使用的：对于替换功能：https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Regular_Expressions 对于嵌套的if语句： https://www.w3schools.com/js/js_if_else.asp
