How do I POST urlencoded form data with $http without jQuery?

Question

I am new to AngularJS, and for a start, I thought to develop a new application using only AngularJS.

I am trying to make an AJAX call to the server side, using

Answer 1

you need to post plain javascript object, nothing else

           var request = $http({
                method: "post",
                url: "process.cfm",
                transformRequest: transformRequestAsFormPost,
                data: { id: 4, name: "Kim" }
            });

            request.success(
                function( data ) {
                    $scope.localData = data;
                }
            );

if you have php as back-end then you will need to do some more modification.. checkout this link for fixing php server side

Answer 2

This worked for me. I use angular for front-end and laravel php for back-end. In my project, angular web sends json data to laravel back-end.

This is my angular controller.

var angularJsApp= angular.module('angularJsApp',[]);
angularJsApp.controller('MainCtrl', function ($scope ,$http) {

    $scope.userName ="Victoria";
    $scope.password ="password"


       $http({
            method :'POST',
            url:'http://api.mywebsite.com.localhost/httpTest?callback=JSON_CALLBACK',
            data: { username :  $scope.userName , password: $scope.password},
            headers: {'Content-Type': 'application/json'}
        }).success(function (data, status, headers, config) {
            console.log('status',status);
            console.log('data',status);
            console.log('headers',status);
        });

});

This is my php back-end laravel controller.

public function httpTest(){
        if (Input::has('username')) {
            $user =Input::all();
            return  Response::json($user)->setCallback(Input::get('callback'));
        }
    }

This is my laravel routing

Route::post('httpTest','HttpTestController@httpTest');

The result in browser is

status 200
data JSON_CALLBACK({"username":"Victoria","password":"password","callback":"JSON_CALLBACK"}); httpTesting.js:18 headers function (c){a||(a=sc(b));return c?a[K(c)]||null:a}

There is chrome extension called postman. You can use to test your back-end url whether it is working or not. https://chrome.google.com/webstore/detail/postman-rest-client/fdmmgilgnpjigdojojpjoooidkmcomcm?hl=en

hopefully, my answer will help you.

Answer 3

Here is the way it should be (and please no backend changes ... certainly not ... if your front stack does not support application/x-www-form-urlencoded, then throw it away ... hopefully AngularJS does !

$http({
     method: 'POST',
     url: 'api_endpoint',
     headers: {'Content-Type': 'application/x-www-form-urlencoded'},
     data: 'username='+$scope.username+'&password='+$scope.password
 }).then(function(response) {
    // on success
 }, function(response) {
    // on error
 });

Works like a charm with AngularJS 1.5

People, let give u some advice:

• use promises .then(success, error) when dealing with $http, forget about .sucess and .error callbacks (as they are being deprecated)

• From the angularjs site here "You can no longer use the JSON_CALLBACK string as a placeholder for specifying where the callback parameter value should go."

If your data model is more complex that just a username and a password, you can still do that (as suggested above)

$http({
     method: 'POST',
     url: 'api_endpoint',
     headers: {'Content-Type': 'application/x-www-form-urlencoded'},
     data: json_formatted_data,
     transformRequest: function(data, headers) {
          return transform_json_to_urlcoded(data); // iterate over fields and chain key=value separated with &, using encodeURIComponent javascript function
     }
}).then(function(response) {
  // on succes
}, function(response) {
  // on error
});

Document for the encodeURIComponent can be found here

Answer 4

All of these look like overkill (or don't work)... just do this:

$http.post(loginUrl, `username=${ encodeURIComponent(username) }` +
                     `&password=${ encodeURIComponent(password) }` +
                     '&grant_type=password'
).success(function (data) {

Answer 5

$http({

    method: "POST",
    url: "/server.php",
    headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
    data: "name='Олег'&age='28'",


}).success(function(data, status) {
    console.log(data);
    console.log(status);
});
