Getting a user ID from a mention
提问by OffstageAlmond
I want to get a Users ID from a mention. I am making a user info command so the author of the message will not always be them so I cannot do message.author.id. I have used substrings to split the command into the command itself and the mention but I cannot turn the mention into an ID.
我想从提及中获取用户 ID。我正在制作一个用户信息命令，所以消息的作者并不总是他们，所以我不能做message.author.id。我使用子字符串将命令拆分为命令本身和提及，但我无法将提及转换为 ID。
I am aware that discords mentions are actually <@USERID>, which is another way I could get the ID. Please tell me if I am able to get rid of the <@>so I am left with the ID, or turn the mention itself into an one using another method. I have looked through the docs and I am not aware of anything that could help me.
我知道 discords 提到的实际上是<@USERID>，这是我获得 ID 的另一种方式。请告诉我我是否能够摆脱<@>这样我留下的 ID，或者使用另一种方法将提及本身变成一个。我已经浏览了文档，但我不知道有什么可以帮助我的。

You can do that in two ways: if you want to use the mention as an argument, you can remove the mention characters with regex, like this: yourstring.replace(/[\\<>@#&!]/g, "");.
The other way to do that is to get the first mention in the message and then the user's id: message.mentions.users.first().id.
你可以这样做有两种方式：如果你想使用提及作为参数，你可以用正则表达式中删除提及的人物，像这样：yourstring.replace(/[\\<>@#&!]/g, "");。
另一种方法是获取消息中的第一个提及，然后获取用户的 id: message.mentions.users.first().id。
