How to pass parameters to $http in angularjs?

Question

Assume that I have two input boxes with corresponding ng-model as fname and lname. If I call http request as :

$http({method:\'GET\', url:\'/search\', params         


        

Answer 1

We can use input data to pass it as a parameter in the HTML file w use ng-model to bind the value of input field.

<input type="text" placeholder="Enter your Email" ng-model="email" required>

<input type="text" placeholder="Enter your password " ng-model="password" required> 

and in the js file w use $scope to access this data:

$scope.email="";
$scope.password="";

Controller function will be something like that:

 var app = angular.module('myApp', []);

    app.controller('assignController', function($scope, $http) {
      $scope.email="";
      $scope.password="";

      $http({
        method: "POST",
        url: "http://localhost:3000/users/sign_in",
        params: {email: $scope.email, password: $scope.password}

      }).then(function mySuccess(response) {
          // a string, or an object, carrying the response from the server.
          $scope.myRes = response.data;
          $scope.statuscode = response.status;

        }, function myError(response) {
          $scope.myRes = response.statusText;
      });
    });

Answer 2

Build URL '/search' as string. Like

"/search?fname="+fname"+"&lname="+lname

Actually I didn't use

 `$http({method:'GET', url:'/search', params:{fname: fname, lname: lname}})` 

but I'm sure "params" should be JSON.stringify like for POST

var jsonData = JSON.stringify(
    {
        fname: fname,
        lname: lname 
    }
);

After:

$http({
  method:'GET',
  url:'/search',
  params: jsonData
});

Here is a simple mathed to pass values from a route provider

//Route Provider
$routeProvider.when("/page/:val1/:val2/:val3",{controller:pageCTRL, templateUrl: 'pages.html'});


//Controller
$http.get( 'page.php?val1='+$routeParams.val1 +'&val2='+$routeParams.val2 +'&val3='+$routeParams.val3 , { cache: true})
        .then(function(res){
            //....
        })

Here is how you do it:

$http.get("/url/to/resource/", {params:{"param1": val1, "param2": val2}})
    .then(function (response) { /* */ })...

Angular takes care of encoding the parameters.

Maxim Shoustin's answer does not work ({method:'GET', url:'/search', jsonData} is not a valid JavaScript literal) and JeyTheva's answer, although simple, is dangerous as it allows XSS (unsafe values are not escaped when you concatenate them).
