javascript - 如何检查某人是否有特定角色(How to check if someone has a certain role)

Question

Ok, I know that there are similar questions out there but no matter what I try I get the same result.

(好的，我知道那里也有类似的问题，但是不管我尝试什么，我都会得到相同的结果。)

I have been trying for 2 days now to figure out how to check if I had the "OverBot-Admin" role for a ban command.

(我已经尝试了2天，以弄清楚如何检查我是否具有ban命令的“ OverBot-Admin”角色。)

But whenever I run the command it spams the chat!

(但是，每当我运行命令时，它就会向聊天室发送垃圾邮件！)

Here is my code:

(这是我的代码：)

      if (command === "ban") {
    if(message.member.roles.has(role => role.name === "OverBot-Admin")) {
      let reason = args.slice(1).join(" ");
      if (!reason) reason = "No reason provided";
      const user = message.mentions.users.first();

      if (user) {
        const member = message.guild.member(user);

        if (member) {
          member
            .ban({ reason: "They were being bad." })
            .then(() => {
              message.reply(
                ":white_check_mark: Successfully banned " +
                  message.user.id +
                  "for " +
                  reason
              );

              const embed = new Discord.RichEmbed()
                .setTitle("Ban")
                .addField("Member:", message.user.id)
                .addField("Reason:", reason)
                .setTimestamp()
                .setFooter(
                  "Created by OverThrow, OverBot SE",
                  "https://cdn.discordapp.com/avatars/649431468254429224/0b63291c1e7342c2320ca5c3cce806ca.png?size=2048"
                );
            })
            .catch(err => {
              message.reply(":x: I was unable to ban that member!");

              console.error(err);
            });
        } else {
          message.reply(":x: That user isn't a member to this guild!");
        }
      } else {
        message.reply(":x: You didn't mention a member to ban!");
      }
    }
  } else {
    message.reply(":x: I couldn't ban this user, please make sure you have the OverBot-Admin role!")
  }

message.member.roles.has() requires a role ID as an argument, whereas here, you are passing in a function.

(message.member.roles.has()需要角色ID作为参数，而在这里，您要传入一个函数。)

The method I think you are looking for is Collection.exists (although this method is deprecated, if anyone can figure out a different way to go about this, please let me know).

(我认为您正在寻找的方法是Collection.exists （尽管不建议使用此方法，但是如果有人可以找到其他解决方法，请告诉我）。)

Looking at the message.reply in the then function after banning, I see a message.user.id .

(望着message.reply在then取缔后的功能，我看到一个message.user.id 。)

However, message.user does not seem to be a valid property of the message object according to the docs.

(但是，根据文档， message.user似乎不是消息对象的有效属性。)

I assume that you would be referring to the user who was just banned, in which case you can reuse the user or member variable you previously defined.

(我假设您是指刚刚被禁止的用户，在这种情况下，您可以重用先前定义的user或member变量。)
