我正在设置一个新的服务器,并且希望运行一个nodejs脚本来解决问题。但问题是,它在脚本启动/或运行后发布错误。
我试着在GitHub上联系“作者”,但没有回答,我也试过在其他我在线的服务器上进行测试,但它说的是同样的错误。(包括下调nodejs/npm版本的评级)
我找到的代码来自于这个GitHub页面:https://github.com/Triniayo/nodejs-discord-csgoupdate
// Requirements
const { Client } = require('discord.js');
const fs = require('fs');
const Parser = require('rss-parser');
const htmlToText = require('html-to-text');
const log = require('npmlog');
// Load Config
const cfg = require('./config.json');
// Create feeder instance
let rssParser = new Parser({
// Renaming 'content:encoded' to 'contentHtml' because it won't be useable otherwise
customFields: {
item: [
['content:encoded', 'contentHtml']
]
},
// Setting User Agent
headers: {
'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/69.0.3497.100 Safari/537.36'
}
});
// Setting variables for the RSS output
let updateTitle;
let updateURL;
let updateContent;
let updateDate;
// Setting last update variable
let lastUpdate;
function getLastUpdate() {
// Getting date of last update from check-update.txt file
let dateFromFile = fs.readFileSync('check-update.txt');
lastUpdate = dateFromFile.toString();
}
// Getting last date from check-update.txt file every 5 seconds
setInterval(getLastUpdate, 5000);
// Create Discord Bot Instance
const bot = new Client();
// Logging into Bot Account
bot.on('ready', () => {
log.info('discord', `Logged in as ${bot.user.tag} (User ID: ${bot.user.id}) on ${bot.guilds.size} server(s)`);
bot.user.setActivity('Fetching Updates');
// Checking every 10 seconds if there's a new update, and if it's been posted already
setInterval(getUpdate, 10000);
});
function getUpdate() {
// Get current date and edit format
let getDate = new Date();
let date = [
getDate.getFullYear(),
('0' + (getDate.getMonth() + 1)).slice(-2),
('0' + getDate.getDate()).slice(-2)
].join('-');
// Fetching updates from CS:GO Blog
(async () => {
// Setting RSS Feed URL
let feed = await rssParser.parseURL('http://blog.counter-strike.net/index.php/category/updates/feed/');
// Setting items into variables
feed.items.forEach(item => {
if (item.isoDate.includes(`${date}`)) {
updateTitle = item.title;
updateURL = item.link;
updateContent = item.contentHtml;
updateDate = item.isoDate;
}
});
// Converting from HTML to readable text
let format = htmlToText.fromString(updateContent, {
wordwrap: 130
});
// Limiting the update to 10 lines
let updateNotes = format.split('\n', 10);
if (updateDate.includes(`${date}`)) {
if (lastUpdate !== date) {
bot.channels.get(cfg.channelid).send("@everyone A new CS:GO Update has been released!", {
embed: {
"title": `${updateTitle}`,
"description": `${updateNotes.join('\n')}...\n\n[Continue reading on the CS:GO Blog](${updateURL})`,

}
}
});

fs.writeFileSync('check-update.txt', `${date}`)
}
} else {
// Do nothing if update has been posted already.
}
})();
}

bot.login(cfg.token);下面是错误,我是在将nodejs & npm更新到最新版本后得到的。

(node:23692) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). (rejection id: 13)我不知道,这个错误意味着什么,因为我是nodejs的新手。
国家预防机制/节点的版本:
node: v8.16.1
npm: 6.12.0我一定是改变了什么。我对javascript或nodejs没有感觉。这个脚本可以自由地放在GitHub上。
更新:编辑10/10/2019-15:28:使用日期格式做什么?-示例;在github上,它使用这种格式阅读check-update.txt : 10/23/2018 (例如)
好像它不会给我发不和谐的帖子。(如果它不这么做的话,它应该这么做)
示例:
// Checking every 10 seconds if there's a new update, and if it's been posted already
setInterval(getUpdate, 10000);以下是问题所在:
// Do nothing if update has been posted already.
}
})();
}也许我应该从不和谐的开发者那里创造一个新的机器人?

改变它。请求url http到https,isoDate向pubDate请求。isoDate不在提要内容中。
// Setting RSS Feed URL
let feed = await rssParser.parseURL('https://blog.counter-strike.net/index.php/category/updates/feed/');
// Setting items into variables
feed.items.forEach(item => {
if (item.pubDate.includes(`${date}`)) {
updateTitle = item.title;
updateURL = item.link;
updateContent = item.contentHtml;
updateDate = item.pubDate || '';
}
});发布于 2019-10-10 12:37:55
您发布的错误如下:
(node:23692) UnhandledPromiseRejectionWarning: TypeError: Cannot read property 'includes' of undefined
at /home/mikkel/bots/csgo/app.js:87:24
at <anonymous>
at process._tickCallback (internal/process/next_tick.js:189:7)错误消息的第一行是说试图调用includes,或者获取对象的includes属性,但是对象没有定义。错误消息的第二行告诉您问题发生在何处;第87行(和第24列)。
第87行内容如下:
if (updateDate.includes(`${date}`)) {因此,updateDate对象必须以某种方式未定义。综上所述,我们发现它仅在第70行的forEach循环中设置,但它位于此循环内的if语句中。
feed.items.forEach(item => {
if (item.isoDate.includes(`${date}`)) {
updateTitle = item.title;
updateURL = item.link;
updateContent = item.contentHtml;
updateDate = item.isoDate;
}
});如果循环从未运行,那么updateDate将永远不会被设置。如果循环中的每个项都不包括它们的isoDate属性中的日期,那么updateDate将永远不会被设置。
因此,我们必须警惕这些案件。
通过将第87行更改为以下内容,我们可以添加将updateDate设置为某些内容的条件:
if (updateDate && updateDate.includes(`${date}`)) {https://stackoverflow.com/questions/58322866
