我是mundodb的新用nodejs.I想要更新评论数据。这是我的文件

 {
       "__v": NumberInt(0),
       "_id": ObjectId("565443b1172e19d51f98b0ed"),
       "address": "tohana",
       "comments": [
         {
           "_id": ObjectId("5654455fe088d89c20736e3c"),
           "comment": "good man",
           "uemail": "dinesh@gmail.com",
           "uname": "dinesh" 
        },
         {
           "_id": ObjectId("565445e471dce6ca20705a84"),
           "comment": "nice person",
           "uemail": "kr@gmail.com",
           "uname": "krishan" 
        },
         {
           "_id": ObjectId("5654460e7aa73bec2064060e"),
           "comment": "bad person",
           "uemail": "Rai",
           "uname": "Rahul" 
        } 
      ],
       "email": "nishantg@ocodewire.com"▼,
       "name": "Nishant" 
    }

我在前端使用Angular js，在后端使用nodeJs。这是我的代码：

app.post('/commentsSave/:id', function(req, res) {
var id = req.params.id; // userId
var input = JSON.parse(JSON.stringify(req.body)); //commentData
var commentId = input.id; //commentId
var name  = input.name;
var email = input.email;
var comment = input.comment
res.send({data:id,data2:input});

})
