I have an api that receives this json:

{
    "instructions":[
        {
            "A":9,
            "B":1,
            "move":"moveover"
        },
        {
            "A":8,
            "B":1,
            "move":"moveover"
        }
        ],
        "length":10,
        "res":""
}

And the next one comes back to me:

{
  "instructions": [
    {
      "A": 9,
      "B": 1,
      "move": "moveover"
    },
    {
      "A": 8,
      "B": 1,
      "move": "moveover"
    }
  ],
  "length": 10,
  "res": "Position [0] :  0Position [1] :  1 9 8Position [2] :  2Position [3] :  3Position [4] :  4Position [5] :  5Position [6] :  6Position [7] :  7Position [8] : Position [9] : "
}

I take the data from the following web page / form: What I do is save the values of A, B and movements in an array, for example:

//lo que tendria en memoria 
var A=[1,3,5,8];
var B=[5,6,7,10];
var moves=[moveinto,moveover,pileover,pileinto];
//añadiendo los valores al array 
$scope.addMove = function () {
     A.push($scope.addA);
     B.push($scope.addB);
     moves.push($scope.addMov);
}

my question is how to assemble the json to be able to send it by post?

One idea I had was:

for (var i = 0; i < serverA.length; i++) {
      objetoJson[i] = {
        "instructions": [{
          "A": serverA[i],
          "B": serverB[i],
          "move": serverMove[i]
        }],
        "length": $scope.blockLength,
        "res": null
      };

but it did not work for me, now what I did was send it manually and if it works for me:

json = {
      "instructions": [{
          "A": 9,
          "B": 1,
          "move": "moveover"
        },
        {
          "A": 8,
          "B": 1,
          "move": "moveover"
        }
      ],
      "length": 10,
      "res": ""
    }
    $http.post("http://localhost:56493/api/BlocksProblem", json)
      .then(function (data) {
        $scope.result = data;
      }, function (response) {
        $scope.result = response;
      });

Could you tell me how to put my json together?

Your problem is that you are generating an arrangement of objects when what you have to generate is an object with a key instructions that has as value an arrangement, this is arranged generating the arrangement of instructions and then generating the object with the keys that you need:

First, since your controller already generates the structure of the instructions as follows:

var instructions = [];

$scope.addMove = function () {

    instructions.push({
        A: $scope.addA,
        B: $scope.addB,
        move: $scope.addMov
    });
}

later create your json in the following way:

json = {
    instructions: instructions,
    length: $scope.blockLength,
    res: ""
}

And you're ready to send it to your API.

Greetings!

I recommend you to manage everything as an array and then at the moment you need the Json, you will pair it in this way:

var json = [1,2,3,4];
var data = JSON.parse(json);

ALREADY SOLVED, THANK YOU TO ALL, THIS WAS MY SOLUTION:

reading is stackoverflow in English I found this:

link

So I proceeded to create mine:

    //Guardo los valores que obtengo del form en arrays 
    var serverMove = [];
    var serverA = [];
    var serverB = [];
    //create the json 
    var jsonS = {
          instructions: [],
          "length": $scope.blockLength,
          "res": ""
    };
       //lleno dinamicamente unicamente la parte de instrucciones
        for (var i = 0; i < serverA.length; i++) {
          jsonS.instructions.push({
            "A": serverA[i],
            "B": serverB[i],
            "move": serverMove[i]
          })
        }

the resulting json is something like this:

{ 
    "instructions": [
        { 
            "A": 1
            , "B": 3,
            "move": 
            "moveonto" 
        },
        { 
            "A": 5,
            "B": 9, 
            "move": "pileover" 
        } 
        ], 
        "length": 22, 
        "res": "" 
}

I hope it will be useful to someone
