REST API

Question

{ 
    "_id": "58be5a4a031372098578b1d6", 
    "name": "A", 
    "email": "abc@gmail.com", 
    "username": "A.a", 
    "password": "$2a$05$GAF1hP91EowKUTKr14ASL.MRd2lOjotfOgVlEghwnqctNcIe5seNW", 
    "latitude": 12, 
    "longitude": 72, 
    "profilePic": "images/A.png", 
    "__v": 9, 
    "isBuddyEnabled": true, 
    "friendRequests": [ 
    { 
     "friendId": "58be7aa0c204cb134068975d", 
     "isAccepted": true 
    }, 
    { 
     "friendId": "58bf8cb4c26d5811b188a600", 
     "isAccepted": false 
    } 
    ], 
    "friends": [ 
    "58be7aa0c204cb134068975d" 
    ], 
    "networkContacts": [ 
    { 
     "profession": "doctor" 
    } 
    ], 
    "interests": [ 
    "sports", 
    "music" 
    ] 
} 

我有一個用戶上面的JSON，現在我需要這樣的json的數組的所有信息，其friendRequest isAccepted是假的，這意味着這些請求正在等待對他來說， 爲如：當我打API /請求/ 58be5a4a031372098578b1d6 =>我得ID的信息58bf8cb4c26d5811b188a600

到現在我能中檢索其請求，通過下面的查詢

app.post('/api/users/requests/:id'function(req,res){User.find({"_id":req.params.id}) 
    .find({"friendRequests.isAccepted":false},function(err,callback){}}) 

Answer 1

可以使用不被接受的ID彈出陣列過濾器根據過濾

User.find({"_id":req.params.id}, function (err, user) { 

    var friendRequests = user.friendRequests.filter(function (fr) { 
    return fr.isAccepted == false; 
    }).pop(); 

    console.log(friendRequests); //logs { "friendId": "58bf8cb4c26d5811b188a600", "isAccepted": false 
});
