在 Javascript 中生成一组 UUID [英] Generate an array of UUID's in Javascript

问题描述

使用诸如 uuid 之类的模块如何生成以下结构.

<预><代码>['d9baea4e-2436-4481-accb-7c2fe835039e'，'60152666-8c2c-4d33-a5c8-da1dda106c5d'，'c4eaa558-83cc-4b94-9aff-1aefdc204794','273998e3-3138-41eb-b740-28ee53f7e344']

我是否正确地假设这可以通过 Promise 来完成，或者至少可以给出这样的方法.

解决方案

uuid 实际上是一个同步功能，根据文档.所以一个简单的循环就可以:

const uuidv4 = require('uuid/v4');const ids = [];for(让 i=0;i<10;i++){ids.push(uuidv4());}

或者如果你愿意，你也可以做一个单线:

const ids = Array(4).fill().map(() => uuid());

Using a module such as uuid how could I generate the following structure.

[
    'd9baea4e-2436-4481-accb-7c2fe835039e',
    '60152666-8c2c-4d33-a5c8-da1dda106c5d', 
    'c4eaa558-83cc-4b94-9aff-1aefdc204794', 
    '273998e3-3138-41eb-b740-28ee53f7e344'
]

Would I be right in assuming this could be done with a Promise or at least could such an approach be given.

解决方案

uuid is actually a synchronous function, per the docs. So a simple loop would do:

const uuidv4 = require('uuid/v4');
const ids = [];
for(let i=0;i<10;i++){
  ids.push(uuidv4());
}

Or you can also do a one-liner if you like:

const ids = Array(4).fill().map(() => uuid());
