带有 meme subreddit 的 Discord.js meme 命令将图像返回为

Question

我正在制作一个从 meme subreddit 发送随机 meme 的 meme 命令，在发现除了嵌入中的实际图像之外的所有内容后，我将图像记录到控制台并返回403错误。如果有人能够提供帮助，将不胜感激。

代码：

const https = require('https');

const Discord = require('discord.js');

const url = 'https://www.reddit.com/r/meme/hot/.json?limit=100'

module.exports = {

    name: 'meme',

    description: 'sends meme',

    execute(message, args) {

        https.get(url, (result) => {

            var body = ''

            result.on('data', (chunk) => {

                body += chunk

            })

            result.on('end', () => {

                var response = JSON.parse(body)

                var index = response.data.children[Math.floor(Math.random() * 99) + 1].data

                if (index.post_hint !== 'image') {

                    var text = index.selftext

                    const textembed = new Discord.MessageEmbed()

                        .setTitle(subRedditName)

                        .setColor(9384170)

                        .setDescription(`[${title}](${link})\n\n${text}`)

                        .setURL(`https://reddit.com/${subRedditName}`)

                    message.channel.send(textembed)

                }

                var image = index.preview.images[0].source.url

                var title = index.title

                var link = 'https://reddit.com' + index.permalink

                var subRedditName = index.subreddit_name_prefixed

                if (index.post_hint !== 'image') {

                    const textembed = new Discord.RichEmbed()

                        .setTitle(subRedditName)

                        .setColor(9384170)

                        .setDescription(`[${title}](${link})\n\n${text}`)

                        .setURL(`https://reddit.com/${subRedditName}`)

                    message.channel.send(textembed)

                }

     

Answer 1

我已经尝试了您的代码，并且看到&图像中的 URL 被编码为&（例如https://preview.redd.it/z8jsjzvkhq051.jpg?auto=webp&s=bb492d4861f48b62da806584f26bcc15f4d6663a：） Redd.it 无法理解它并返回 403 错误。只需将图像 URL 中的&to替换为&它对我有用。const https = require('https');const Discord = require('discord.js');const url = 'https://www.reddit.com/r/meme/hot/.json?limit=100'module.exports = {    name: 'meme',    description: 'sends meme',    execute(message, args) {        https.get(url, (result) => {            var body = ''            result.on('data', (chunk) => {                body += chunk            })            result.on('end', () => {                var response = JSON.parse(body)                var index = response.data.children[Math.floor(Math.random() * 99) + 1].data                if (index.post_hint !== 'image') {                    var text = index.selftext                    const textembed = new Discord.MessageEmbed()                        .setTitle(subRedditName)                        .setColor(9384170)                        .setDescription(`[${title}](${link})\n\n${text}`)                        .setURL(`https://reddit.com/${subRedditName}`)                    message.channel.send(textembed)                }                var image = index.preview.images[0].source.url.replace('&', '&')                var title = index.title                var link = 'https://reddit.com' + index.permalink                var subRedditName = index.subreddit_name_prefixed                if (index.post_hint !== 'image') {                    const textembed = new Discord.RichEmbed()                        .setTitle(subRedditName)                        .setColor(9384170)                        .setDescription(`[${title}](${link})\n\n${text}`)                        .setURL(`https://reddit.com/${subRedditName}`)                    message.channel.send(textembed)                }                console.log(image);                const imageembed = new Discord.MessageEmbed()                    .setTitle(subRedditName)                    .setImage(image)                    .setColor(9384170)                    .setDescription(`[${title}](${link})`)                    .setURL(`https://reddit.com/${subRedditName}`)                message.channel.send(imageembed)            }).on('error', function (e) {                console.log('Got an error: ', e)            })        })    },}

Answer 2

我调整了代码以使其适用于任何 subreddit。所以你只需做（前缀）meme funny，它会在前 100 个或更少的帖子中搜索 subreddit “funny”。我还添加了一个 nsfw 检查。如果您不在 discord 的 nsfw 频道中，那么它将遍历前 100 个帖子中的每一个，并检查它是否是 nsfw。如果是，那么它将从我将每个帖子推入的数组中删除。如果它找不到非 nsfw 帖子，那么它会在聊天中告诉你。但是，如果您在 nsfw 聊天中，那么它只会从它找到的前 100 个帖子中随机选择一个帖子。旁注：我找不到检查 subreddit 是否存在的方法，所以我只是检查结果是否超过 1000 个字符。任何存在的 subreddit 都应该有超过 1000 个字符。任何不存在的字符都应少于 1000 个字符。const prefix = '.'const args = message.content.substring(1).split(" ")if (message.content.startsWith(prefix){&nbsp; &nbsp; if (args[0] == 'meme'){&nbsp; &nbsp; &nbsp; &nbsp; if (args[1] != null){&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; var url = `https://www.reddit.com/r/${args[1]}/hot/.json?limit=100`&nbsp; &nbsp;

Answer 3

这有点难以阅读，因为您重复了两次代码块（两个文本嵌入和 img 嵌入）第一个[Math.floor(Math.random() * 99) + 1]=>[Math.floor(Math.random() * 100)] 第二个使它可以选择任何值，第一个永远不能为0。试试这个（在索引变量后插入代码）const isImage = index.post_hint === "image";const subRedditName = index.subreddit_name_prefixed;const title = index.title;const link = 'https://reddit.com' + index.permalink;const text = !isImage && index.selfText;const desc = `[${title}](${link})`;const embed = new Discord.MessageEmbed()&nbsp; &nbsp; .setTitle(subRedditName)&nbsp; &nbsp; .setColor(9384170)&nbsp; &nbsp; .setDescription(desc + (text ? `\n\n${text}` : ""))&nbsp; &nbsp; .setURL(`https://reddit.com/${subRedditName}`);if (isImage) {&nbsp; &nbsp; const img = index.preview.images[0].source.url;&nbsp; &nbsp; embed.setImage(img);}messsage.channel.send(embed);
