如何将随机谷歌图像搜索添加到不和谐机器人

Question

我在使用 discord.js 时遇到了问题，我在 2 小时前就做对了，但我尝试向其中添加另一个图像搜索，但现在我无法将其恢复到原来的状态。我尝试重新组织小块代码、括号、括号和分号，我什至尝试在 Visual Studio 中撤消我的更改。

     switch(args[0]) {
             case 'iDog':
               image(msg);
               break;
           }
           //emoji commands
           switch(args[0]) {
             case 'eYOUTUBE':
               if(args[1] === 'emoji') {
                 msg.react('668632526641692680')
               } else {
                 msg.reply('You must specify either 5 things'); //I'll decide the things later or learn how to react with a uploaded emoji
               }
             break;
             case 'eTWITTER':
              if(args[1] === 'emoji') {
                msg.react('668632550742163457')

              case 'eREDDIT':

            switch(args[0]){

                        }else{
                          msg.reply('ERROR, PLEASE TYPE REDDIT FOLLOWED BY PROF');
                        }
                        break;



                        case 'clear':
                          if(!args[1]) {
                            msg.reply('ERROR')
                          } else {

                        }

     })


     function iDog(msg) {

      var options = {
        url: "http://results.dogpile.com/serp?qc=images&q=" + "dog",

          $ = cheerio.load(responseBody);


          var links = $(".image a.link");

          var urls = new Array(links.length).fill(0).map((v, i) => links.eq(i).attr("href"));

          console.log(urls);

          if (!urls.length) {

              return;
          }

          // Send result
          msg.channel.send( urls[Math.floor(Math.random() * urls.length)]);
      });


     }


    //bot uses the token ID to login
    bot.login(token);

如果我在底部附近输入function image(msg)，当我输入不和谐时，什么都不会弹出，因为我显然必须这样做function iDog(msg)，但是当我这样做时，文本会稍微变暗，当我将鼠标悬停在它上面时，它说“iDog 已声明，但从未被读取”，我在终端中收到错误“图像未定义”

Answer 1

尝试改变

function iDog(msg) {

到

function image(message) {
