帶有 meme subreddit 的 Discord.js meme 命令將圖像返回為

JavaScript

神不在的星期二 2022-07-08 17:48:34

我正在制作一個從 meme subreddit 發送隨機 meme 的 meme 命令，在發現除了嵌入中的實際圖像之外的所有內容后，我將圖像記錄到控制臺并返回403錯誤。如果有人能夠提供幫助，將不勝感激。代碼：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) }

我已經嘗試了您的代碼，并且看到&圖像中的 URL 被編碼為&（例如https://preview.redd.it/z8jsjzvkhq051.jpg?auto=webp&s=bb492d4861f48b62da806584f26bcc15f4d6663a：） Redd.it 無法理解它并返回 403 錯誤。

只需將圖像 URL 中的&to替換為&它對我有用。

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)

})

}

我調整了代碼以使其適用于任何 subreddit。所以你只需做（前綴）meme funny，它會在前 100 個或更少的帖子中搜索 subreddit “funny”。我還添加了一個 nsfw 檢查。如果您不在 discord 的 nsfw 頻道中，那么它將遍歷前 100 個帖子中的每一個，并檢查它是否是 nsfw。如果是，那么它將從我將每個帖子推入的數組中刪除。如果它找不到非 nsfw 帖子，那么它會在聊天中告訴你。但是，如果您在 nsfw 聊天中，那么它只會從它找到的前 100 個帖子中隨機選擇一個帖子。

旁注：我找不到檢查 subreddit 是否存在的方法，所以我只是檢查結果是否超過 1000 個字符。任何存在的 subreddit 都應該有超過 1000 個字符。任何不存在的字符都應少于 1000 個字符。

const prefix = '.'

const args = message.content.substring(1).split(" ")

if (message.content.startsWith(prefix){

if (args[0] == 'meme'){

if (args[1] != null){

var url = `https://www.reddit.com/r/${args[1]}/hot/.json?limit=100`

} else {

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

}

https.get(url, (result) => {

var body = ''

var chunked = false

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

body += chunk

if (chunked == false){

chunked = true

}

})

result.on('end', () => {

if (body.length > 1000){

var response = JSON.parse(body)

var postChildren = []

if (message.channel.nsfw == false){

var postsNumber = 0

for (var number = 0; number < response.data.children.length; number++){

postChildren.push(number)

}

for (var found = false; found == false; postsNumber ++){

if (postChildren.length > 0){

var index1 = Math.floor(Math.random() * (postChildren.length))

var index2 = postChildren[index1]

if (response.data.children[index2].data.over_18 == true){

postChildren.splice(index1, 1)

} else {

var index = response.data.children[index2].data

var found = true

}

} else {

var found = true

}

} else {

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

}

if (postChildren.length > 0 || message.channel.nsfw){

var title = index.title

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

var subRedditName = index.subreddit_name_prefixed

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

var text = index.selftext

if (title.length > 256) {

title = (title.substring(0, 253) + "...")

}

if (text.length > 2048) {

text = (text.substring(0, 2045) + "...")

}

const textembed = new Discord.MessageEmbed()

.setTitle(title)

.setColor('#ff0000')

.setDescription(text)

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

message.channel.send(textembed)

}

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

var image = index.preview.images[0].source.url.replace('&', '&')

if (title.length > 256) {

title = (title.substring(0, 253) + "...")

}

const imageembed = new Discord.MessageEmbed()

.setTitle(title)

.setImage(image)

.setColor('#ff0000')

.setURL(link)

message.channel.send(imageembed)

}

} else {

message.channel.send('Could not find a meme that was not nsfw')

}

} else {

message.channel.send('Could not find subreddit!')

}

}).on('error', function (e) {

console.log('Got an error: ', e)

})

這有點難以閱讀，因為您重復了兩次代碼塊（兩個文本嵌入和 img 嵌入）

第一個[Math.floor(Math.random() * 99) + 1]=>[Math.floor(Math.random() * 100)] 第二個使它可以選擇任何值，第一個永遠不能為0。

試試這個（在索引變量后插入代碼）

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()

.setTitle(subRedditName)

.setColor(9384170)

.setDescription(desc + (text ? `\n\n${text}` : ""))

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

if (isImage) {

const img = index.preview.images[0].source.url;

embed.setImage(img);

}

messsage.channel.send(embed);
