my question need angular js send json file , json should saved database using rest services.. idea achieve using angular fr client..

witrh angular, easiest way use $resource. in case, that:

var app = (...)  app.factory('driverpropfacaderest', function($resource) {     return $resource('http://(...)/driverprops/:id', {id:'@id'}); });  app.controller('driverpropcontroller', function($scope, driverpropfacaderest) {     var inputdata = { 'driverid': 'value', (...) };     driverpropfacaderest.save(inputdata, function(data) {         console.log(data);         (...)     }); }); 

see link in angular reference documentation more details: https://docs.angularjs.org/api/ngresource/service/$resource.

you use low level api $http, described below:

app.controller('driverpropcontroller', function($scope, $http) {     var inputdata = { 'driverid': 'value', (...) };     $http.post('http://(...)/driverprops', inputdata)          .success(function(data, status, headers, config) {               // callback called asynchronously               // when response available          })          .error(function(data, status, headers, config) {               // called asynchronously if error occurs               // or server returns response error status.          }); }); 

see link in angular reference documentation more details: https://docs.angularjs.org/api/ng/service/$http#post.

hope helps you, thierry
