从文件夹 discord.js 获取随机图像

Question

Hi I am trying to fetch a random image out of a folder and make the discord bot send it. When I type the command I get the following error: (node:15184) UnhandledPromiseRejectionWarning: Error: ENOENT: no such file or directory, stat 'c:\Users\Charlie\Desktop\discordbot2\t.png'

Here is my code:

var fs = require('fs');
client.on("message",message=>{
  if(message.content==('image')){
    console.log("image")
    var files = fs.readdirSync('folder')
    var chosenFile = files[Math.floor(Math.random() * files.length)] 
    console.log(chosenFile)
    message.channel.send(
      {
        files : [
          chosenFile
        ]
      }
    )
  }
})

Answer 1

The pathname you pass to message.channel.send() in the files option is just the file name. It's supposed to be a path (relative to the current directory, or absolute), which is how it's interpreted. As the chosen file isn't in the current directory, it generates the ENOENT "no such file or directory" error.

To make a relative path, you can use path.join , passing the both the path to the directory holding the file and the file name:

const path = require('path');
...
    message.channel.send({files: [path.join('folder', chosenFile)] })
