将json数据与javascript合并

Question

我得到了一个这样的 JSON 文件。 我需要合并来自同一个证书名称的名称和值。

使用 javascript 执行此操作的最佳方法是什么？

    [
        {
          certname: 'server1',
          environment: 'acceptance',
          name: 'clientcert',
          value: 'server1'
        },
        {
          certname: 'server2',
          environment: 'acceptance',
          name: 'clientcert',
          value: 'server2'
        },
        {
          certname: 'server3',
          environment: 'acceptance',
          name: 'clientcert',
          value: 'server3'
        }
    ],
    ]    
        {
          certname: 'server1',
          environment: 'acceptance',
          name: 'operatingsystem',
          value: 'windows'
        },
        {
          certname: 'server2',
          environment: 'acceptance',
          name: 'operatingsystem',
          value: 'windows'
        },
        {
          certname: 'server3',
          environment: 'acceptance',
          name: 'operatingsystem',
          value: 'RedHat'
        }
   ],
   [
        {
          certname: 'server1',
          environment: 'acceptance',
          name: 'operatingsystemmajrelease',
          value: '2008 R2'
        },
        {
          certname: 'server2',
          environment: 'acceptance',
          name: 'operatingsystemmajrelease',
          value: '2008 R2'
        },
        {
          certname: 'server3',
          environment: 'acceptance',
          name: 'operatingsystemmajrelease',
          value: '6'
        }
    ],
    [
        {
          certname: 'server1',
          environment: 'acceptance',
          name: 'clientversion',
          value: '5.5.2'
        },
        {
          certname: 'server2',
          environment: 'acceptance',
          name: 'clientversion',
          value: '5.5.2'
        },
        {
          certname: 'server3',
          environment: 'acceptance',
          name: 'clientversion',
          value: '5.5.2'
        }
    ]

我需要合并来自同一个证书名称的名称和值。

结果必须是：

var endresult= {
  0:{clientcert:"server1", operatingsystem:"windows", operatingsystemmajrelease: "2008 R2", clientversion: 5.5.2}, 
  1:{clientcert:"server2", operatingsystem:"windows", operatingsystemmajrelease: "2008 R2", clientversion: 5.5.2},
  2:{clientcert:"server3", operatingsystem:"RedHat", operatingsystemmajrelease: 6, clientversion: 5.5.2},
};

或者

{
  clientcert: 'server3',
  operatingsystem: 'windows',
  operatingsystemmajrelease: '2008 R2',
  clientversion: '5.5.2'
},
{
  clientcert: 'server2',
  operatingsystem: 'windows',
  operatingsystemmajrelease: '2008 R2',
  clientversion: '5.5.2'
},
{
  clientcert: 'server1',
  operatingsystem: 'RedHat',
  operatingsystemmajrelease: '6',
  clientversion: '5.5.2'
},

我不知道合并回 json 格式或合并到 JS 对象是否更容易，这两种结果都很好。 :-) 我需要将其合并到 SQL 数据库中，所以我认为 JSON 是最好的结果？

Answer 1

 const json = [{certname: 'server1',environment: 'acceptance',name: 'clientcert',value: 'server1'},{certname: 'server2',environment: 'acceptance',name: 'clientcert',value: 'server2'},{certname: 'server3',environment: 'acceptance',name: 'clientcert',value: 'server3'},{certname: 'server1',environment: 'acceptance',name: 'operatingsystem',value: 'windows'},{certname: 'server2',environment: 'acceptance',name: 'operatingsystem',value: 'windows'},{certname: 'server3',environment: 'acceptance',name: 'operatingsystem',value: 'RedHat'},{certname: 'server1',environment: 'acceptance',name: 'operatingsystemmajrelease',value: '2008 R2'},{certname: 'server2',environment: 'acceptance',name: 'operatingsystemmajrelease',value: '2008 R2'},{certname: 'server3',environment: 'acceptance',name: 'operatingsystemmajrelease',value: '6'},{certname: 'server1',environment: 'acceptance',name: 'clientversion',value: '5.5.2'},{certname: 'server2',environment: 'acceptance',name: 'clientversion',value: '5.5.2'},{certname: 'server3',environment: 'acceptance',name: 'clientversion',value: '5.5.2'},]; function format(json){ const data = json.reduce((a, b) => { if(!a[b.certname]) a[b.certname] = {}; a[b.certname][b.name] = b.value; return a; }, {}); return Object.values(data); } console.log(format(json));

编辑：根据更新的问题，输入拆分为子数组。 要检查它，您可以：

• 在转到上述解决方案之前合并所有内容，如下所示：

 const json = [[{certname: 'server1',environment: 'acceptance',name: 'clientcert',value: 'server1'},{certname: 'server2',environment: 'acceptance',name: 'clientcert',value: 'server2'},{certname: 'server3',environment: 'acceptance',name: 'clientcert',value: 'server3'}],[{certname: 'server1',environment: 'acceptance',name: 'operatingsystem',value: 'windows'},{certname: 'server2',environment: 'acceptance',name: 'operatingsystem',value: 'windows'},{certname: 'server3',environment: 'acceptance',name: 'operatingsystem',value: 'RedHat'}],[{certname: 'server1',environment: 'acceptance',name: 'operatingsystemmajrelease',value: '2008 R2'},{certname: 'server2',environment: 'acceptance',name: 'operatingsystemmajrelease',value: '2008 R2'},{certname: 'server3',environment: 'acceptance',name: 'operatingsystemmajrelease',value: '6'}],[{certname: 'server1',environment: 'acceptance',name: 'clientversion',value: '5.5.2'},{certname: 'server2',environment: 'acceptance',name: 'clientversion',value: '5.5.2'},{certname: 'server3',environment: 'acceptance',name: 'clientversion',value: '5.5.2'}],]; function format(json){ const data = json.reduce((a,b)=>[...a, ...b], []).reduce((a, b) => { if(!a[b.certname]) a[b.certname] = {}; a[b.certname][b.name] = b.value; return a; }, {}); return Object.values(data); } console.log(format(json));

• 或者迭代reduce内的子数组，如下所示：

 const json = [[{certname: 'server1',environment: 'acceptance',name: 'clientcert',value: 'server1'},{certname: 'server2',environment: 'acceptance',name: 'clientcert',value: 'server2'},{certname: 'server3',environment: 'acceptance',name: 'clientcert',value: 'server3'}],[{certname: 'server1',environment: 'acceptance',name: 'operatingsystem',value: 'windows'},{certname: 'server2',environment: 'acceptance',name: 'operatingsystem',value: 'windows'},{certname: 'server3',environment: 'acceptance',name: 'operatingsystem',value: 'RedHat'}],[{certname: 'server1',environment: 'acceptance',name: 'operatingsystemmajrelease',value: '2008 R2'},{certname: 'server2',environment: 'acceptance',name: 'operatingsystemmajrelease',value: '2008 R2'},{certname: 'server3',environment: 'acceptance',name: 'operatingsystemmajrelease',value: '6'}],[{certname: 'server1',environment: 'acceptance',name: 'clientversion',value: '5.5.2'},{certname: 'server2',environment: 'acceptance',name: 'clientversion',value: '5.5.2'},{certname: 'server3',environment: 'acceptance',name: 'clientversion',value: '5.5.2'}],]; function format(json){ const data = json.reduce((a, b) => { b.forEach(t => { if(!a[t.certname]) a[t.certname] = {}; a[t.certname][t.name] = t.value; }) return a; }, {}); return Object.values(data); } console.log(format(json));

const data = [{

const result = {};
data.forEach(val => {

})
JSON.stringify(Object.values(result))
