带有meme subreddit的Discord.js meme命令返回图像为403禁止
带有meme subreddit的Discord.js meme命令返回图像为403禁止
提问于 2020-04-22 01:59:29
我做了一个meme命令，从meme子编辑中随机发送一个meme，在发现除了嵌入中的实际图像之外的所有东西都在工作后，我将图像记录到控制台，它返回了一个403错误。如果有人能帮上忙，我们将不胜感激。
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)
}
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)
})
})
},

我已经尝试过您的代码，并且已经看到图像URL中的&被编码为Redd.it无法理解的& (示例：https://preview.redd.it/z8jsjzvkhq051.jpg?auto=webp&s=bb492d4861f48b62da806584f26bcc15f4d6663a)，并返回403错误。
只需将图像URL中的&替换为&，我就可以使用它了。
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)
})
})

我调整了代码，使它可以与任何subreddit一起工作。所以你只需添加(前缀)表情包搞笑，它就会在前100个或更少的帖子中搜索子subreddit“搞笑”。我还添加了nsfw检查。如果你不在nsfw频道的不和谐上，那么它会检查前100个帖子中的每一个，并检查它是否是nsfw。如果是，那么它将从我推送每个帖子的数组中删除它。如果它找不到非nsfw的帖子，那么它会在聊天中告诉你。然而，如果你在nsfw聊天，那么它会从它找到的前100个帖子中随机挑选一个帖子。
附注:我找不到方法来检查subreddit是否存在，所以我只是让它检查结果是否超过1000个字符。任何存在的subreddit都应该超过1000个字符。任何不存在的字符都应该少于1000个字符。

这有点难读，因为你重复了两次代码块(两个文本嵌入和img嵌入)
first [Math.floor(Math.random() * 99) + 1] => [Math.floor(Math.random() * 100)]，第二个值，所以可以选择任何值，第一个值永远不能是0。
尝试此操作(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()
.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);
}
