AngularJs $ does not send data

The question:

Could anyone tell me why the following statement does not send the post data to the designated url? The url is called but on the server when I print $_POST – I get an empty array. If I print message in the console before adding it to the data – it shows the correct content.

$'request-url',  { 'message' : message });

I’ve also tried it with the data as string (with the same outcome):

$'request-url',  "message=" + message);

It seem to be working when I use it in the following format:

    method: 'POST',
    url: 'request-url',
    data: "message=" + message,
    headers: {'Content-Type': 'application/x-www-form-urlencoded'}

but is there a way of doing it with the $ – and do I always have to include the header in order for it to work? I believe that the above content type is specifying format of the sent data, but can I send it as javascript object?

The Solutions:

Below are the methods you can try. The first solution is probably the best. Try others if the first one doesn’t work. Senior developers aren’t just copying/pasting – they read the methods carefully & apply them wisely to each case.

Method 1

I had the same problem using MVC and found the solution here

There is much confusion among newcomers to AngularJS as to why the
$http service shorthand functions ($, etc.) don’t appear to
be swappable with the jQuery equivalents (, etc.)

The difference is in how jQuery and AngularJS serialize and transmit the data. Fundamentally, the problem lies with your server language of choice being unable to understand AngularJS’s transmission natively … By default, jQuery transmits data using

Content-Type: x-www-form-urlencoded

and the familiar foo=bar&baz=moe serialization.

AngularJS, however, transmits data using

Content-Type: application/json 

and { "foo": "bar", "baz": "moe" }

JSON serialization, which unfortunately some Web server languages—notably
—do not unserialize natively.

Works like a charm.


// Your app's root module...
angular.module('MyModule', [], function($httpProvider) {
  // Use x-www-form-urlencoded Content-Type
  $['Content-Type'] = 'application/x-www-form-urlencoded;charset=utf-8';

   * The workhorse; converts an object to x-www-form-urlencoded serialization.
   * @param {Object} obj
   * @return {String}
  var param = function(obj) {
    var query = '', name, value, fullSubName, subName, subValue, innerObj, i;

    for(name in obj) {
      value = obj[name];

      if(value instanceof Array) {
        for(i=0; i<value.length; ++i) {
          subValue = value[i];
          fullSubName = name + '[' + i + ']';
          innerObj = {};
          innerObj[fullSubName] = subValue;
          query += param(innerObj) + '&';
      else if(value instanceof Object) {
        for(subName in value) {
          subValue = value[subName];
          fullSubName = name + '[' + subName + ']';
          innerObj = {};
          innerObj[fullSubName] = subValue;
          query += param(innerObj) + '&';
      else if(value !== undefined && value !== null)
        query += encodeURIComponent(name) + '=' + encodeURIComponent(value) + '&';

    return query.length ? query.substr(0, query.length - 1) : query;

  // Override $http service's default transformRequest
  $httpProvider.defaults.transformRequest = [function(data) {
    return angular.isObject(data) && String(data) !== '[object File]' ? param(data) : data;

Method 2

It’s not super clear above, but if you are receiving the request in PHP you can use:

$params = json_decode(file_get_contents('php://input'),true);

To access an array in PHP from an AngularJS POST.

Method 3

You can set the default “Content-Type” like this:

$["Content-Type"] = "application/x-www-form-urlencoded";

About the data format:

The $ and $http.put methods accept any JavaScript object (or a string) value as their data parameter. If data is a JavaScript object it will be, by default, converted to a JSON string.

Try to use this variation

function sendData($scope) {
        url: 'request-url',
        method: "POST",
        data: { 'message' : message }
    .then(function(response) {
            // success
    function(response) { // optional
            // failed

Method 4

I have had a similar issue, and I wonder if this can be useful as well:

var xsrf = $.param({fkey: "key"});
    method: 'POST',
    url: url,
    data: xsrf,
    headers: {'Content-Type': 'application/x-www-form-urlencoded'}


Method 5

I like to use a function to convert objects to post params.

myobject = {'one':'1','two':'2','three':'3'}

Object.toparams = function ObjecttoParams(obj) {
    var p = [];
    for (var key in obj) {
        p.push(key + '=' + encodeURIComponent(obj[key]));
    return p.join('&');

    method: 'POST',
    url: url,
    data: Object.toparams(myobject),
    headers: {'Content-Type': 'application/x-www-form-urlencoded'}

Method 6

This has finally been addressed in angular 1.4 using $httpParamSerializerJQLike


.controller('myCtrl', function($http, $httpParamSerializerJQLike) {
  method: 'POST',
  url: baseUrl,
  data: $httpParamSerializerJQLike({
      "email":"[email protected]",
    'Content-Type': 'application/x-www-form-urlencoded'

Method 7

I use jQuery param with AngularJS post requrest. Here is a example … create AngularJS application module, where myapp is defined with ng-app in your HTML code.

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

Now let us create a Login controller and POST email and password.

app.controller('LoginController', ['$scope', '$http', function ($scope, $http) {
    // default post header
    $['Content-Type'] = 'application/x-www-form-urlencoded;charset=utf-8';
    // send login data
        method: 'POST',
        url: '',
        data: $.param({
            email: $,
            password: $scope.password
        headers: {'Content-Type': 'application/x-www-form-urlencoded'}
    }).success(function (data, status, headers, config) {
        // handle success things
    }).error(function (data, status, headers, config) {
        // handle error things

I don’t like to exaplain the code, it is simple enough to understand 🙂 Note that param is from jQuery, so you must install both jQuery and AngularJS to make it working. Here is a screenshot.

enter image description here

Hope this is helpful. Thanks!

Method 8

I had the same problem with AngularJS and Node.js + Express 4 + Router

Router expects the data from post’s request in body. This body was always empty if i followed the example from Angular Docs

Notation 1

$'/someUrl', {msg:'hello word!'})

But if i used it in the data

Notation 2

       withCredentials: false,
       method: 'post',
       url: yourUrl,
       headers: {'Content-Type': 'application/x-www-form-urlencoded'},
       data: postData

Edit 1:

Otherwise node.js router will expect the data in req.body if used notation 1:


Which also sends the information as JSON payload. This is better in some cases where you have arrays in your json and x-www-form-urlencoded will give some problems.

it worked. Hope it helps.

Method 9

Unlike JQuery and for the sake of pedantry, Angular uses JSON format for POST
data transfer from a client to the server (JQuery applies x-www-form-urlencoded presumably, although JQuery and Angular uses JSON for data imput). Therefore there are two parts of problem: in js client part and in your server part. So you need:

  1. put js Angular client part like this:

    method: 'POST',
    url: 'request-url',
    data: {'message': 'Hello world'}


  1. write in your server part to receive data from a client (if it is php).

            $data               = file_get_contents("php://input");
            $dataJsonDecode     = json_decode($data);
            $message            = $dataJsonDecode->message;
            echo $message;     //'Hello world'

Note: $_POST will not work!

The solution works for me fine, hopefully, and for you.

Method 10

To build on @felipe-miosso’s answer:

  1. Download it as an AngularJS module from here,
  2. Install it
  3. Add it to your application:

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

Method 11

To send data via Post methode with $http of angularjs you need to change

data: "message=" + message, with data: $.param({message:message})

Method 12

I don’t have the reputation to comment, but in response/addition to Don F’s answer:

$params = json_decode(file_get_contents('php://input'));

A second parameter of true needs to be added to the json_decode function in order to properly return an associative array:

$params = json_decode(file_get_contents('php://input'), true);

Method 13


  var payload = $.param({ jobId: 2 });

                    method: 'POST',
                    url: 'web/api/ResourceAction/processfile',
                    data: payload,
                    headers: { 'Content-Type': 'application/x-www-form-urlencoded' }

WebAPI 2

public class AcceptJobParams
            public int jobId { get; set; }

        public IHttpActionResult ProcessFile([FromBody]AcceptJobParams thing)
            // do something with fileName parameter

            return Ok();

Method 14

This code solved the issue for me. It is an application-level solution:

  function($httpProvider) {
    $httpProvider.defaults.transformRequest.push(function(data) {
        var requestStr;
        if (data) {
            data = JSON.parse(data);
            for (var key in data) {
                if (requestStr) {
                    requestStr += "&" + key + "=" + data[key];
                } else {
                    requestStr = key + "=" + data[key];
        return requestStr;
    $["Content-Type"] = "application/x-www-form-urlencoded";

Method 15

Add this in your js file:

$["Content-Type"] = "application/x-www-form-urlencoded";

and add this to your server file:

$params = json_decode(file_get_contents('php://input'), true);

That should work.

Method 16

I also faced similar problem and i was doing something like this and that didn’t worked. My Spring controller was not able read data parameter.

var paramsVal={data:'"id":"1"'};
  $"Request URL",  {params: paramsVal});  

But reading this forum and API Doc, I tried following way and that worked for me.
If some one also have similar problem, You can try below way as well.

      method: 'POST',
      url: "Request URL",           
      params: paramsVal,
      headers: {'Content-Type': 'application/x-www-form-urlencoded;charset=utf-8'}

Please check$http#post for what param config does.
{data:’”id”:”1″‘} – Map of strings or objects which will be turned to URL?data=”id:1″

Method 17

this is probably a late answer but i think the most proper way is to use the same piece of code angular use when doing a “get” request using you $httpParamSerializer will have to inject it to your controller
so you can simply do the following without having to use Jquery at all ,


Method 18

In my case I resolve the problem like this :

var deferred = $q.defer();

    method: 'POST',
    url: 'myUri', 
    data: $.param({ param1: 'blablabla', param2: JSON.stringify(objJSON) }),
    headers: { 'Content-Type': 'application/x-www-form-urlencoded' }
    function(res) {
        console.log('succes !',;
    function(err) {
        console.log('error...', err);
return deferred.promise;

You need to use JSON.stringify for each param containing a JSON object, and then build your data object with “$.param” 🙂

NB : My “objJSON” is a JSON object containing array, integer, string and html content. His total size is >3500 characters.

Method 19

I know has accepted answer. But, following might help to future readers, if the answer doesn’t suit them for any reason.

Angular doesn’t do ajax same as jQuery. While I tried to follow the guide to modify angular $httpprovider , I encountered other problems. E.g. I use codeigniter in which $this->input->is_ajax_request() function always failed (which was written by another programmer and used globally, so cant change) saying this was not real ajax request.

To solve it, I took help of deferred promise. I tested it in Firefox, and ie9 and it worked.

I have following function defined outside any of the angular code. This function makes regular jquery ajax call and returns deferred/promise (I’m still learning) object.

function getjQueryAjax(url, obj){
    return $.ajax({
        type: 'post',
        url: url,
        cache: true,
        data: obj

Then I’m calling it angular code using the following code. Please note that we have to update the $scope manually using $scope.$apply() .

    var data = {
        media: "video",
        scope: "movies"
    var rPromise = getjQueryAjax("myController/getMeTypes" , data);
            $scope.testData = JSON.parse(response);
        console.log("AJAX failed!");

This may not be the perfect answer, but it allowed me to use jquery ajax calls with angular and allowed me to update the $scope.

Method 20

I had the same problem in express .. to resolve you have to use bodyparser to parse json objects before sending http requests ..


Method 21

I am using WCF webservices with angular js and below code

        contentType: "application/json; charset=utf-8",//required
        method: "POST",
        url: '../../operation/Service.svc/user_forget',
        dataType: "json",//optional
        data:{ "uid_or_phone": $scope.forgettel, "user_email": $scope.forgetemail },
        async: "isAsync"//optional

       }).success( function (response) {

         $scope.userforgeterror = response.d;                    

Hope it helps.

Method 22

Didn’t find a complete code snippet of how to use $ method to send data to the server and why it was not working in this case.

Explanations of below code snippet…

  1. I am using jQuery $.param function to serialize the JSON data to www post data
  2. Setting the Content-Type in the config variable that will be passed along with the request of angularJS $ that instruct the server that we are sending data in www post format.

  3. Notice the $ method, where I am sending 1st parameter as url, 2nd parameter as data (serialized) and 3rd parameter as config.

Remaining code is self understood.

$scope.SendData = function () {
           // use $.param jQuery function to serialize data from JSON 
            var data = $.param({
                fName: $scope.firstName,
                lName: $scope.lastName

            var config = {
                headers : {
                    'Content-Type': 'application/x-www-form-urlencoded;charset=utf-8;'

            $'/ServerRequest/PostDataResponse', data, config)
            .success(function (data, status, headers, config) {
                $scope.PostDataResponse = data;
            .error(function (data, status, header, config) {
                $scope.ResponseDetails = "Data: " + data +
                    "<hr />status: " + status +
                    "<hr />headers: " + header +
                    "<hr />config: " + config;

Look at the code example of $ method here.

Method 23

If your using PHP this is a easy way to access an array in PHP from an AngularJS POST.

$params = json_decode(file_get_contents('php://input'),true);

Method 24

If using Angular >= 1.4, here’s the cleanest solution using the serializer provided by Angular:

  .config(function ($httpProvider, $httpParamSerializerJQLikeProvider){
    $['Content-Type'] = 'application/x-www-form-urlencoded; charset=utf-8';

And then you can simply do this anywhere in your app:

  method: 'POST',
  url: '/requesturl',
  data: {
    param1: 'value1',
    param2: 'value2'

And it will correctly serialize the data as param1=value1&param2=value2 and send it to /requesturl with the application/x-www-form-urlencoded; charset=utf-8 Content-Type header as it’s normally expected with POST requests on endpoints.


During my research I found that the answer to this problem comes in many different flavors; some are very convoluted and depend on custom functions, some depend on jQuery and and some are incomplete in suggesting that you only need to set the header.

If you just set the Content-Type header, the end point will see the POST data, but it won’t be in the standard format because unless you provide a string as your data, or manually serialize your data object, it will all be serialized as JSON by default and may be incorrectly interpreted at the endpoint.

e.g. if the correct serializer was not set in the above example, it would be seen in the endpoint as:


And that can lead to unexpected parsing, e.g. ASP.NET treats it as a null parameter name, with {"param1":"value1","param2":"value2"} as value; or Fiddler interprets it the other way, with {"param1":"value1","param2":"value2"} as the parameter name, and null as the value.

Method 25

Similar to the OP’s suggested working format & Denison’s answer, except using $ instead of just $http and is still dependent on jQuery.

The good thing about using jQuery here is that complex objects get passed properly; against manually converting into URL parameters which may garble the data.

$ 'request-url', jQuery.param( { 'message': message } ), {
    headers: { 'Content-Type': 'application/x-www-form-urlencoded' }

Method 26

Just put the data you want to send as second parameter:

$'request-url',  message);

Another form which also works is:

$'request-url',  { params: { paramName: value } });

Make sure that paramName exactly matches the name of the parameter of the function you are calling.

Method 27

When I had this problem the parameter I was posting turned out to be an array of objects instead of a simple object.

Method 28

Just updated from angular 1.2 to 1.3, have found a problem in the code. Transforming a resource will lead to an endless-loop because (I think) of the $promise holding again the same object. Maybe it will help someone…

I could fix that by:

 * The workhorse; converts an object to x-www-form-urlencoded serialization.
 * @param {Object} obj
 * @return {String}
var param = function (obj) {
var query = '', name, value, fullSubName, subName, subValue, innerObj, i;

angular.forEach(obj, function(value, name) {
+    if(name.indexOf("$promise") != -1) {
+        return;
+    }

    value = obj[name];
    if (value instanceof Array) {
        for (i = 0; i < value.length; ++i) {

Method 29

I’ve been using the accepted answer’s code (Felipe’s code) for a while and it’s been working great (thanks, Felipe!).

However, recently I discovered that it has issues with empty objects or arrays.
For example, when submitting this object:

    A: 1,
    B: {
        a: [ ],
    C: [ ],
    D: "2"

PHP doesn’t seem to see B and C at all. It gets this:

    "A" => "1",
    "B" => "2"

A look at the actual request in Chrome shows this:

A: 1
D: 2

I wrote an alternative code snippet. It seems to work well with my use-cases but I haven’t tested it extensively so use with caution.

I used TypeScript because I like strong typing but it would be easy to convert to pure JS:

angular.module("MyModule").config([ "$httpProvider", function($httpProvider: ng.IHttpProvider) {
    // Use x-www-form-urlencoded Content-Type
    $["Content-Type"] = "application/x-www-form-urlencoded;charset=utf-8";

    function phpize(obj: Object | any[], depth: number = 1): string[] {
        var arr: string[] = [ ];
        angular.forEach(obj, (value: any, key: string) => {
            if (angular.isObject(value) || angular.isArray(value)) {
                var arrInner: string[] = phpize(value, depth + 1);
                var tmpKey: string;
                var encodedKey = encodeURIComponent(key);
                if (depth == 1) tmpKey = encodedKey;
                else tmpKey = `[${encodedKey}]`;
                if (arrInner.length == 0) {
                else {
                    arr = arr.concat( => `${tmpKey}${inner}`));
            else {
                var encodedKey = encodeURIComponent(key);
                var encodedValue;
                if (angular.isUndefined(value) || value === null) encodedValue = "";
                else encodedValue = encodeURIComponent(value);

                if (depth == 1) {
                else {
        return arr;

    // Override $http service's default transformRequest
    (<any>$httpProvider.defaults).transformRequest = [ function(data: any) {
        if (!angular.isObject(data) || data.toString() == "[object File]") return data;
        return phpize(data).join("&");
    } ];
} ]);

It’s less efficient than Felipe’s code but I don’t think it matters much since it should be immediate compared to the overall overhead of the HTTP request itself.

Now PHP shows:

    "A" => "1",
    "B" => [
        "a" => ""
    "C" => "",
    "D" => "2"

As far as I know it’s not possible to get PHP to recognize that B.a and C are empty arrays, but at least the keys appear, which is important when there’s code that relies on the a certain structure even when its essentially empty inside.

Also note that it converts undefineds and nulls to empty strings.

Method 30

I solved this by below codes:

Client Side (Js):

                url: me.serverPath,
                method: 'POST',
                data: data,
                headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
                success(function (serverData) {
                    console.log("ServerData:", serverData);

notice that data is an object.

On the server (ASP.NET MVC):

        public string Api()
            var data = JsonConvert.DeserializeObject<AgentRequest>(Request.Form[0]);
            if (data == null) return "Null Request";
            var bl = Page.Bl = new Core(this);

            return data.methodName;

and ‘AllowCrossSiteJsonAttribute’ is needed for cross domain requests:

public class AllowCrossSiteJsonAttribute : ActionFilterAttribute
        public override void OnActionExecuting(ActionExecutingContext filterContext)
            filterContext.RequestContext.HttpContext.Response.AddHeader("Access-Control-Allow-Origin", "*");

Hope this was useful.
