Error handling in AngularJS http get then construct

How can I handle an HTTP error, e.g. 500, when using the AngularJS "http get then" construct (promises)?

$http.get(url).then(
    function(response) {
        console.log('get',response)
    }
)

Problem is, for any non 200 HTTP response, the inner function is not called.

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

$http.get(url).success(successCallback).error(errorCallback);

Replace successCallback and errorCallback with your functions.

Edit: Laurent's answer is more correct considering he is using then. Yet I'm leaving this here as an alternative for the folks who will visit this question.

I could not really work with the above. So this might help someone.

$http.get(url)
  .then(
    function(response) {
        console.log('get',response)
    }
  ).catch(
    function(response) {
    console.log('return code: ' + response.status);
    }
  )

See also the $http response parameter.

Try this

function sendRequest(method, url, payload, done){

        var datatype = (method === "JSONP")? "jsonp" : "json";
        $http({
                method: method,
                url: url,
                dataType: datatype,
                data: payload || {},
                cache: true,
                timeout: 1000 * 60 * 10
        }).then(
            function(res){
                done(null, res.data); // server response
            },
            function(res){
                responseHandler(res, done);
            }
        );

    }
    function responseHandler(res, done){
        switch(res.status){
            default: done(res.status + ": " + res.statusText);
        }
    }

You can make this bit more cleaner by using:

$http.get(url)
    .then(function (response) {
        console.log('get',response)
    })
    .catch(function (data) {
        // Handle error here
    });

Similar to @this.lau_ answer, different approach.

If you want to handle server errors globally, you may want to register an interceptor service for $httpProvider:

$httpProvider.interceptors.push(function ($q) {
    return {
        'responseError': function (rejection) {
            // do something on error
            if (canRecover(rejection)) {
                return responseOrNewPromise
            }
            return $q.reject(rejection);
        }
    };
});

You need to add an additional parameter:

$http.get(url).then(
    function(response) {
        console.log('get',response)
    },
    function(data) {
        // Handle error here
    })
