$http get request with angularjs

I’m very new to AngularJS and I’m trying to make a weather app just for practice.
as weather service i use: https://openweathermap.org. my http request does not work, here’s my code:

angular.module("weather", []).controller('WeatherController', function($scope,$http){
    
$scope.getWeather = function() {
    $http.get('https://api.openweathermap.org/data/2.5/weather?q=London&appid=69f76656f3a6e0a34db5e6052e851f76', config).then(function successCallback(response){
        console.log(response);
    }, function errorCallback() {
        console.log('error');
    }) 
}
        
    
      
   
});

<div class="n-p-b" ng-app="weather" ng-controller="WeatherController">
<button ng-click="getWeather()">click</button>
    <img src="png/righr-arrow .png" class="arrow-right">
    <div class="card" style="width: 50rem; height: 35rem; border-radius: 5%; box-shadow: 0 0 2rem rgba(0, 0, 255, 0.1);">
        <img src="img/blue.png" class="card-img-top" alt="...">
        <div class="card-body" style="padding: 0%;">
           <div class="b-card">
            <div class="twitter">
                <p>Twitter Feed</p>
            </div>

            <div class="weather-week">
                <p>mon</p>
                <p>tue</p>
                <p>wed</p>
                <p>thu</p>
                <p>fri</p>
                <p>sat</p>
                <p>sun</p>
            </div>
           </div>

          </div>
      </div>
    <img src="png/left-arrow.png" class="arrow-left">
    
</div>

I tried to use different forms of requests(shortcut etc),different links, but it does not work
