Question

现在我可以通过使用nodejs将postgres数据库作为json输出查询来获取数据，如下所示

[{"headers":["id","name","description","type","actionmode","outputparser","dispatchtype","troubleticketaction","alarmaction","actionexecutionmode","cost","isparent__"],"values":["100","test_bsc_interface","test_bsc_interface","test","Open Loop","regex","HPSA",null,null,"Asynchronous",null,"0"]},{"headers":["id","name","description","type","actionmode","outputparser","dispatchtype","troubleticketaction","alarmaction","actionexecutionmode","cost","isparent__"],"values":["101","check_tt","check_tt","test","Open Loop","None","Trouble Ticket","check_tt",null,"Synchronous",null,"0"]}

我期待输出，其中应该避免重复的标题。这是什么方法？下面是我尝试的代码片段仍然无法正常工作，我也使用_.each。请任何人告诉我解决方案

var result = _.map(json_object, function(o) {
                    return {headers:keys[0], values : _.values(o)}
                });

[{"headers":["id","name","description","type","actionmode","outputparser","dispatchtype","troubleticketaction","","actionexecutionmode","cost","isparent__"],"values":["100","test_bsc_interfacalarmactione","test_bsc_interface","test","Open Loop","regex","HPSA",null,null,"Asynchronous",null,"0"]},,"values":["101","check_tt","check_tt","test","Open Loop","None","Trouble Ticket","check_tt",null,"Synchronous",null,"0"]}

我认为你的问题来自我回答的另一篇文章：

How to format the JSON object key/value pair

var _ = require('lodash');

var data = [
  { id: '714', actionname: 'test_bsc_interface', actionid: '100' },
  { id: '715', actionname: 'list_all_available_interfaces', actionid: '103' },
  { id: '716', actionname: 'check_tt', actionid: '101' }
];

var result;

if (_.size(data) > 0) {
  result = {
    headers: _.keys(data[0]),
    values: _.map(data, function(o) {
      return _.values(o);
    })
  };
}

console.dir(result);

，输出为：

{ 
  headers: [ 'id', 'actionname', 'actionid' ],
  values: [ 
    [ '714', 'test_bsc_interface', '100' ],
    [ '715', 'list_all_available_interfaces', '103' ],
    [ '716', 'check_tt', '101' ] 
  ] 
}
