Getting this error:

angular.min.js:122 TypeError: $http.get(…).success is not a function
at getUserInfo (app.js:7)
at new (app.js:12)
at Object.invoke (angular.min.js:43)

Here is my code:

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

gitHub.controller('mainController', ['$scope', '$http', function($scope, $http) {

    var $scope.user = '';
    function getUserInfo($scope, $http){ 
        $http.get('https://api.github.com/users')
            .success(function (result) {
                $scope.user = result;
                console.log(result);
            });
    };
    getUserInfo($scope, $http);
}]);

and here is the html

<!DOCTYPE html>
<html ng-app="gitHub">
<head>
    <title>Github Users Directory</title>
    <script src="angular.min.js"></script>
    <script src="app.js"></script>
</head>
<body>
    <div ng-controller="mainController">
        <div>
            <h1>GitHub Users</h1>
            Who do you want to search for?<input type="text" name="FindHim" ng-model="queryName" />
            <button ng-click="getUserInfo()">Search</button>
        </div>
        <div>
            {{ user }}
        </div>

    </div>
</body>
</html>
How to&Answers:

The .success and .error methods are deprecated and have been removed from AngularJS 1.6. Use the standard .then method instead.

$http.get('https://api.github.com/users')
  .then(function (response) {

    var data = response.data;
    var status = response.status;
    var statusText = response.statusText;
    var headers = response.headers;
    var config = response.config;

    $scope.user = data;
    console.log(data);
});

Deprecation Notice

The $http legacy promise methods .success and .error have been deprecated and will be removed in v1.6.0. Use the standard .then method instead.

— AngularJS (v1.5) $http Service API Reference — Deprecation Notice.

Also see SO: Why are angular $http success/error methods deprecated?.

Answer:

i think you need to use .then and not .success when using angular.

Example from the doc’s

var promise = asyncGreet('Robin Hood');
promise.then(function(greeting) {
  alert('Success: ' + greeting);
}, function(reason) {
  alert('Failed: ' + reason);
}, function(update) {
  alert('Got notification: ' + update);
});

Here is the example of how $Http uses it:

// Simple GET request example:
$http({
  method: 'GET',
  url: '/someUrl'
}).then(function successCallback(response) {
    // this callback will be called asynchronously
    // when the response is available
  }, function errorCallback(response) {
    // called asynchronously if an error occurs
    // or server returns response with an error status.
  });

And finally your code could look like this

$scope.getUserInfo = function () {
    $http.get('https://api.github.com/users')
        .then(function (result) {
            $scope.user = result;
            console.log(result);
        }, function(result) {
            //some error
            console.log(result);
        });
};

Answer:

this works

https://docs.angularjs.org/api/ng/service/$http

// Simple GET request example:
$http({
  method: 'GET',
  url: '/someUrl'
}).then(function successCallback(response) {
    // this callback will be called asynchronously
    // when the response is available
  }, function errorCallback(response) {
    // called asynchronously if an error occurs
    // or server returns response with an error status.
  });

Answer:

As per your current implementation, You are not passing arguments (i.e. $scope and $http) to getUserInfo from ng-click="getUserInfo()" thus you are getting the error.

You don’t need to pass these as arguments as $scope and $http as its already injected in controller and define the function in $scope.

gitHub.controller('mainController', ['$scope', '$http', function($scope, $http) {

    $scope.user = '';
    //Redefined function, without arguments
    $scope.getUserInfo = function (){ 
        $http.get('https://api.github.com/users')
            .success(function (result) {
                $scope.user = result;
                console.log(result);
            });
    };
    $scope.getUserInfo();
}]);

Answer:

You dont need to inject $scope, $http..

app.controller('MainController', function($scope, $http) { 
  $scope.fetchData = function(_city){
    $http.get("../api/AllPlaces?filter[where][placeCity]="+ _city)
    .then(function(response) {
      $scope.Data = response.data;
    });
  }
});

Answer:

No need to pass $http as a function parameter, since you have already injected $http as a dependency to your controller. I have made some modification to the code. Please check it will work fine for you.

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

gitHub.controller('mainController', ['$scope', '$http', function ($scope, $http) {

    $scope.user = '';

    $scope.getUserInfo = function() {
        $http.get('https://api.github.com/users')
            .success(function (result) {
                $scope.user = result;
                console.log(result);
            });
    };
    $scope.getUserInfo();
}]);

Answer:

According to Angular JS $http documentation, this system has been excludede from 1.4.3 + So, I have taken help from his post and you can try this way

app.controller('MainCtrl', function ($scope, $http){
   $http({
      method: 'GET',
      url: 'api/url-api'
   }).then(function (success){

   },function (error){

   });
}

OR

$http.get('api/url-api').then(successCallback, errorCallback);

function successCallback(response){
    //success code
}
function errorCallback(error){
    //error code
}

I prefer the second one which was more flexible for me.

Answer:

$http({
    method: 'GET',
    url: '....',
    headers: {
        'Authorization': 'Bearer ' + localStorage["token"]
    }
})
.then(function (data, status, headers, config) {
     alert(JSON.stringify(data) + "Status" + status);
})
.error(function (data, status, headers, config) {
     alert(JSON.stringify(data) + "Status" + status);
});

Answer:

function successCallback(response) {
return response
}
$http.get('url')
.then(successCallback)
