ReferenceError: $httpProvider is not defined
<p>This is my script.</p>

<pre><code>var rtsTaxi =  angular.module("rtsTaxi",['ngAnimate', 'ui.bootstrap']);\
rtsTaxi.config(['$httpProvider',function($httpProdvider)
{
           $httpProvider.defaults.headers.post['Content-Type'] = 'application/json;charset=utf-8';
           $httpProdvider.defaults.useXDomain = true;
           delete $httpProdvider.defaults.headers.common['X-Requested-With'];
}]);
rtsTaxi.controller("bookingController",function($scope){
var message ="Success";
$scope.bookNow = function()
{
     $http({
     method : 'POST',
     url: 'request-url',
     data: {messages : message},
     header : { 'Content-Type' : 'application/json; charset-utf-8'}
     });
};
</code></pre>

<p>When I run my application, Chrome console give me a Reference error for $httpProvider. I have tried other solutions in StackOverflow but still I am having the issue</p>
