AngularJS $http custom header for all requests

I was wondering if there is any way to configure all $http requests header with adding custom info. Something like config :

 var config = {headers: {
            'Authorization': 'Basic d2VudHdvcnRobWFuOkNoYW5nZV9tZQ==',
            'Accept': 'application/json;odata=verbose'
        }
    };

But for all $http calls I will make in different services. I'm sure there is a solution :D.Thanks

You can create a $http interceptor to extend your header:

myapp.factory('httpRequestInterceptor', function () {
  return {
    request: function (config) {

      config.headers['Authorization'] = 'Basic d2VudHdvcnRobWFuOkNoYW5nZV9tZQ==';
      config.headers['Accept'] = 'application/json;odata=verbose';

      return config;
    }
  };
});

myapp.config(function ($httpProvider) {
  $httpProvider.interceptors.push('httpRequestInterceptor');
});

A simpler solution could be to use Angular's run block:

app.run(['$http', function ($http) {
    $http.defaults.headers.common['Authorization'] = 'Basic d2VudHdvcnRobWFuOkNoYW5nZV9tZQ==';
    $http.defaults.headers.common['Accept'] = 'application/json;odata=verbose';
}]);

Note: This solution allows you to pass the static value only one time since the run block executes only once.
