如何访问嵌套的JSON数据

Question

我正在尝试访问Nodejs(discord.js(中的消息

{
"627832600865800222": {                 //guild id
"348832732647784460": {             // author id
"message": "hii hello"
}
}
}

let author_id = message.author.id
let guild_id = message.guild.id
let out = msg [guild_id].author_id.message 
console.log(out)

预期输出：你好

但结果输出：未定义在guild_id之后，输出是未定义的

Answer 1

更改let out = msg [guild_id].author_id.message

至let out = msg[guild_id][author_id].message
