Javascript 节点MySQL-发送前编辑响应

我正在使用

Node

和

MySQL

。我在节点中从MySQL中提取数据，如下所示：

app.get('/getposts', (req, res) => {
   connection.query("SELECT * FROM posts", function(err, rows, fields){
        if(err){
            console.log(err);
        }
        else if(rows.length) {
            res.send(rows)             // <= Edit this res before sending.
        }
        else {
            res.send('No Posts')
        }
    });
});

[
  1: {id:1, name:'post1', desc: 'post1 desc' },
  2: {id:2, name:'post2', desc: 'post2 desc' },
  3: {id:3, name:'post3', desc: 'post3 desc' }
]

我想在发送之前编辑响应。我希望

id

是

键

，

值

是

post

。像1我想要

1:{id:1，name:'post1'，desc:'post1 desc'}

。因此，整个响应应该如下所示：

app.get('/getposts', (req, res) => {
   connection.query("SELECT * FROM posts", function(err, rows, fields){
        if(err){
            console.log(err);
        }
        else if(rows.length) {
            res.send(rows)             // <= Edit this res before sending.
        }
        else {
            res.send('No Posts')
        }
    });
});

[
  1: {id:1, name:'post1', desc: 'post1 desc' },
  2: {id:2, name:'post2', desc: 'post2 desc' },
  3: {id:3, name:'post3', desc: 'post3 desc' }
]

---

我怎样才能做到这一点？非常感谢。

你需要这样的东西

var jsonObj = [
    {id:1, name:'post1', desc: 'post1 desc' },
    {id:2, name:'post2', desc: 'post2 desc' },
    {id:3, name:'post3', desc: 'post3 desc' }
];

var keyArr = [];

for(var index in jsonObj){
    var obj = {};
    obj[jsonObj[index].id] = jsonObj[index];
    keyArr.push(obj);

}

console.log(keyArr);

注意：这不是一个有效的json或数组

[
  1: {id:1, name:'post1', desc: 'post1 desc' },
  2: {id:2, name:'post2', desc: 'post2 desc' },
  3: {id:3, name:'post3', desc: 'post3 desc' }
]

最好的替代方案是

[ { '1': { id: 1, name: 'post1', desc: 'post1 desc' } },
  { '2': { id: 2, name: 'post2', desc: 'post2 desc' } },
  { '3': { id: 3, name: 'post3', desc: 'post3 desc' } } ]
