Question

这是json格式

[ { baseurl: 'http://localhost:5051/springbootdemo/getServerData',
    server: '1' },
  { baseurl: 'http://localhost:5052/springbootdemo/getServerData',
    server: '1' },
  { baseurl: 'http://localhost:5053/springbootdemo/getServerData',
    server: '2' },
  { baseurl: 'http://localhost:5054/springbootdemo/getServerData',
    server: '2' } ]

我想以这种形式重新安排

[
  {server:1 , urls: [
    "http://localhost:5051/springbootdemo/getServerData",
    "http://localhost:5052/springbootdemo/getServerData"
  ]},
  {server:2 , urls: [
    "http://localhost:5053/springbootdemo/getServerData",
    "http://localhost:5054/springbootdemo/getServerData"
  ]}`enter code here`
]

我想要上述格式的重新安排。

首先，它不是JSON-它是一个普通数组。其次，您可以像这样使用reduce：

const arr = [{baseurl:'http://localhost:5051/springbootdemo/getServerData',server:'1'},{baseurl:'http://localhost:5052/springbootdemo/getServerData',server:'1'},{baseurl:'http://localhost:5053/springbootdemo/getServerData',server:'2'},{baseurl:'http://localhost:5054/springbootdemo/getServerData',server:'2'}];
const res = Object.values(arr.reduce((a, { baseurl, server }) => {
  (a[server] = a[server] || { server: +server, urls: [] }).urls.push(baseurl);
  return a;
}, {}));

console.log(res);

.as-console-wrapper { max-height: 100% !important; top: auto; }

以要求的格式格式化json数组
