使用 Discord Javascript Bot 的 Message.Edit 函数错误

Question

我正在尝试组装一个机器人，它可以将谷歌图像搜索结果检索到一个嵌入中，该嵌入“刷新/更改”页面到下一个图像/结果。现在，这个脚本有一个弹出的反应菜单，但是点击它时，我得到一个错误，上面写着：

       message.edit(gglembed(currentIndex))
                                             ^

TypeError: gglembed is not a function

代码：

    case 'rimg':
        var parts = message.content.split(' ');
        var search = parts.slice(1).join(" ");
        var options = {
            url: "http://results.dogpile.com/serp?qc=images&q=" + search,
            method: "GET",
            headers: {
                "Accept": "text/html",
                "User-Agent": "Chrome"
            }
        };
        request(options, function(error, response, responseBody) {


                $ = cheerio.load(responseBody); // load responseBody into cheerio (jQuery)

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


                var urls = new Array(links.length).fill(0).map((v, i) => links.eq(i).attr("href"));
                var imgresults = urls[Math.floor(Math.random() * urls.length)];
                console.log(urls);
                const gglembed = new Discord.MessageEmbed()

                    .setTitle('Image Search Results from  ' + message.author.tag)
                    .setImage(imgresults);
                message.channel.send({
                    embed: gglembed
                }).then(imgsearchembedr => {
                        if (imgresults.length <= 2) {
                            return;
                        }
                        message.react('➡️')
                        const filter = (reactions, user) => true;
                        const collector = message.createReactionCollector(
                            // only collect left and right arrow reactions from the message author
                            (reaction, user) => ['⬅️', '➡️'].includes(reaction.emoji.name) && user.id === message.author.id,
                            // time out after a minute
                            {
                                time: 60000
                            });

                    let currentIndex = urls + 1;
                    collector.on('collect', reaction => {
                        message.reactions.removeAll().then(async () => {
                            reaction.emoji.name === '⬅️' ? currentIndex -= 10 : currentIndex += 10
                            message.edit(gglembed(currentIndex))
                            if (currentIndex !== 0) {
                                await message.react('⬅️')
                            } else {
                                if (currentIndex + 10 < urls.length) message.react('➡️')
                            }
                        })
                    })
                })
        })
break;

任何帮助将不胜感激，谢谢。

您正在尝试将参数传递给您的 MessageEmbed？那是行不通的。要使用嵌入编辑消息，您必须执行message.edit(gglembed)。你想根据变量currentIndex 持有的内容以某种方式编辑嵌入，我说得对吗？如果是这种情况，您必须解释该变量应该做什么，因为我在您的代码中看不到这一点（我看不出该变量应该如何影响您的嵌入......）

编辑： 好的，要对嵌入消息做出反应，您必须执行以下操作：（我只替换了代码的重要部分）

//create a variable embedMessage which holds the message sent by the bot
const embedMessage = await message.channel.send({
                   embed: gglembed
               }).then(imgsearchembedr => {
                   if (imgresults.length <= 2) {
                       return;
                   }
               });
               embedMessage.react('➡️')
               const filter = (reactions, user) => true;
               const collector = embedMessage.createReactionCollector(
               // only collect left and right arrow reactions from the message author
                   (reaction, user) => ['⬅️', '➡️'].includes(reaction.emoji.name) && user.id === message.author.id,
                   // time out after a minute
                   {
                       time: 60000
                   }
               );
               let currentIndex = urls + 1;
               collector.on('collect', reaction => {
                   embedMessage.reactions.removeAll().then(async () => {
                       reaction.emoji.name === '⬅️' ? currentIndex -= 10 : currentIndex += 10
                       await embedMessage.edit(gglembed)
                       if (currentIndex !== 0) {
                           await embedMessage.react('⬅️')
                       } else {
                           if (currentIndex + 10 < urls.length) message.react('➡️')
                       }
                  })
              })```
