問題描述

我對 JS 還很陌生，為了學習，我決定為 Discord 制作一個機器人，我學到了很多東西，并且還在繼續學習.我有一個自動角色"的想法.我知道傳統的做法.

I am fairly new to JS, and to learn I decided to make a bot for Discord, I have learned a lot and am continuing to learn. I had the idea for an "autorole". I know the conventional way of doing it.

bot.on('guildMemberAdd', member => {
  var role = member.guild.roles.find('name', 'Member');
  member.addRole(role);
});

但是，我希望它從 .json 文件中獲取角色.其余代碼都很好，我可以使用 >autorole Role 寫入 json.我只是不確定如何將 json 合并到 member.addRole(role).

However, I want it to get the role from a .json file. The rest of the code is fine, I can write to the json with >autorole Role. I am just unsure on how to incorporate the json into the member.addRole(role).

我的 json 看起來像這樣:

My json looks like this:

{
  "505107608391254026": {
    "role": "Staff"
  }
}

我嘗試過并且認為可行的方法如下.請記住，在有人決定將我列入嘗試學習和失敗的名單之前，我還是個新手.

What I tried, and thought would work is the following. Please remember I am very new before someone decides to slate me for trying to learn and failing.

首先我嘗試了這個:

let auto = JSON.parse(fs.readFileSync("./Storage/autorole.json", "utf8"));
bot.on('guildMemberAdd', member => {
  var role = member.guild.roles.find('name', auto.role);
  member.addRole(role);
});

失敗后，我嘗試了這個.

After that failed, I tried this.

let auto = JSON.parse(fs.readFileSync("./Storage/autorole.json", "utf8"));
bot.on('guildMemberAdd', member => {
  var role = auto.role;
  member.addRole(role);
});

推薦答案

我在我的 discord 機器人中使用了相同的方法.根據您的代碼，您可以在 json 文件中的不和諧 ID 下列出每個用戶的角色.

I am using the same method in my discord bot. From what I can tell by your code, you have roles for each user listed under their discord ids in your json file.

我沒有意識到那是公會 ID.我已更改以下代碼以適應它.

I didn't realize that was the guild ID. I have changed the below code to accommodate that.

如果您還沒有將文件定義為可用變量，那么您首先需要:

You will want to start out by defining your file as a usable variable if you haven't already:

var jsonPath = 'path to json here';
var jsonRead = fs.readFileSync(jsonPath);
var jsonFile = JSON.parse(jsonRead);

接下來，在 json 文件中定義公會的 id:

Next, define the guild's id in the json file:

bot.on('guildMemberAdd', member => {
    var guildId = member.guild.id;
    let autoRole = jsonFile[guildId]
})

既然已經完成了，我們現在可以將我們想要賦予的角色定義為 autoRole.role

Since that is done, we can now define the role we want to give as autoRole.role

我的完整代碼是:

var jsonPath = 'path to json here';
var jsonRead = fs.readFileSync(jsonPath);
var jsonFile = JSON.parse(jsonRead);

bot.on('guildMemberAdd', member => {
    var guildId = member.guild.id;
    let autoRole = jsonFile[guildId]
    let myRole = member.guild.roles.find(role => role.name === autoRole.role);
    member.addRole(myRole)
})

為了幫助您在評論中提出問題，您可以添加 if (!jsonFile[guildId]) 和 else 語句.換句話說，如果您的對象不存在，請執行此操作.

To help with what you asked in your comment, you could add if (!jsonFile[guildId]) with an else statement. In other words, if your object doesn't exist, do this.

代碼:

var jsonPath = 'path to json here';
var jsonRead = fs.readFileSync(jsonPath);
var jsonFile = JSON.parse(jsonRead);

bot.on('guildMemberAdd', member => {
    var guildId = member.guild.id;
    if (!jsonFile[guildId]) {
        console.log('Role could not be found')
    } else {
        let autoRole = jsonFile[guildId]
        let myRole = member.guild.roles.find(role => role.name === autoRole.role);
        member.addRole(myRole)
    }
})
