带有 meme subreddit 的 Discord.js meme 命令将图像返回为 403 禁止

问题描述

我正在制作一个 meme 命令，从 meme subreddit 发送一个随机 meme，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.

I'm making a meme command that sends a random meme from the meme subreddit and after discovering everything except the actual image in embed was working I logged the image to console and it returned a 403 error. If anyone is able to help it would be greatly appreciated.

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})

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

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


}

推荐答案

我试过你的代码，看到图片URL中的&被编码为&(示例:https://preview.redd.it/z8jsjzvkhq051.jpg?auto=webp&s=bb492d4861f48b62da806584f26bcc15f4d6663a)Redd.it 无法理解并返回一个403 错误.

I have tried your code and have seen that the & in the image URL is encoded to & (example: https://preview.redd.it/z8jsjzvkhq051.jpg?auto=webp&s=bb492d4861f48b62da806584f26bcc15f4d6663a) that Redd.it can't understand it and returns a 403 error.

只需将图片 URL 中的 & 替换为 & 即可.

Just replace the & to & in the image URL and it worked for me.

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})

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

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