AngularJS $httpParamSerializer Service
Last Updated :
08 Feb, 2023
The AngularJS $httpParamSerializer service is a service that is used to serialize data into a URL-encoded string. It is commonly used with the AngularJS $http service to encode request parameters when making HTTP requests.
Syntax:
app.controller('myCtrl', function($scope, $http, $httpParamSerializer) {
// Serialize an object into a URL-encoded string
var serializedData = $httpParamSerializer({
foo: 'bar',
baz: 42
});
});
Parameter: The AngularJS $httpParamSerializer function takes a single object as its parameter.
Return value: It returns a URL-encoded string representation of the object.
Here is an example of using the $httpParamSerializer function:
app.controller('myCtrl', function($scope, $http, $httpParamSerializer) {
// Serialize an object into a URL-encoded string
var serializedData = $httpParamSerializer({
foo: 'bar',
baz: 42
});
});
In this example, the $httpParamSerializer function is called with an object containing two properties: foo and baz. The function returns a URL-encoded string representation of the object, which might look something like this:
foo=bar&baz=42
Here is an example of using the $httpParamSerializer service to serialize data for an HTTP post request:
app.controller('myCtrl', function($scope, $http, $httpParamSerializer) {
var data = {
foo: 'bar',
baz: 42
};
// Serialize the data into a URL-encoded string
var serializedData = $httpParamSerializer(data);
// Make the HTTP request
$http.post('https://example.com/api', serializedData, {
headers: {
'Content-Type': 'application/x-www-form-urlencoded'
}
}).then(function(response) {
// Success
}, function(response) {
// Error
});
});
Here is an example of using the AngularJS $httpParamSerializer service to make an HTTP GET request with URL-encoded request parameters:
app.controller('myCtrl', function($scope, $http, $httpParamSerializer) {
// Serialize the form data into a URL-encoded string
var serializedData = $httpParamSerializer($scope.formData);
// Make the HTTP request
$http.get('https://example.com/api', {
params: serializedData,
headers: {
'Content-Type': 'application/x-www-form-urlencoded'
}
}).then(function(response) {
// Success
}, function(response) {
// Error
});
});
Example 1: In this example, we have an AngularJS app with a single controller called mainCtrl. The mainCtrl controller has a scope function called submitForm which is called when the form is submitted. The submitForm function uses the $httpParamSerializer service to serialize the form data into a URL-encoded string and then uses the AngularJS $http service to make an HTTP POST request with the serialized data as the request body. The Content-Type header is set to application/x-www-form-urlencoded to indicate that the request body is URL-encoded.

<!doctype html>
<html ng-app="myApp">
<head>
<script src=

<script>
var app = angular.module('myApp', []);
app.controller('mainCtrl',
function ($scope, $http, $httpParamSerializer) {
$scope.submitForm = function () {
// Serialize the form data into a URL-encoded string
var serializedData = $httpParamSerializer($scope.formData);
// Make the HTTP request(Here, we
// are using the Demo HTTP request)
headers: {
'Content-Type': 'application/x-www-form-urlencoded'
}
}).then(function (response) {
// Success
}, function (response) {
// Error
});
};
});
</script>
</head>
<body ng-controller="mainCtrl">
<form ng-submit="submitForm()"
ng-model="formData">
<label>Name:</label>
<input type="text"
ng-model="formData.name" required>
<br>
<label>Email:</label>
<input type="email"
ng-model="formData.email" required>
<br>
<button type="submit">
Submit
</button>
</form>
</body>
</html>

Example 2: Here is an example of using the AngularJS $http service to send an HTTP POST request with an XML payload. Here, we define an AngularJS app and controller that uses the $http service to send an HTTP POST request with an XML payload. We create a scope variable called xmlData that holds the XML data. The XML data is sent in the request as the body data, and the ‘Content-Type’ header is set to ‘application/xml’ to indicate that the request contains XML data. The response is handled by the then method of the $http.post request, which logs the response in the browser’s console.
