How do I get the HTTP response status code in AngularJS 1.2

You can use the promiss callbacks then, catch and finally after the $resource call.

For example. If you want to catch an error after a call, you would do something like this:

RestAPI.save({resource}, {data}, callbackFunction).$promise.catch(function(response) {
    //this will be fired upon error
    if(response.status == 500) alert('Something baaad happend');
}).then(function() {
    //this will be fired upon success
});

The response object will have status and the statusText properties. status being an integer status code and statusText the text. You'll also have the data property containing the server response.

edit: as suggested, it was response.status

You must add an interceptor inside your resource declaration. Like this:

var resource = $resource(url, {}, {
    get: {
        method: 'GET'
        interceptor: {
            response: function(response) {      
                var result = response.resource;        
                result.$status = response.status;
                return result;
            }
        }
    }                            
});

Usage:

resource.get(params, function(result) {
    console.log(result.$status)
});

IMO status code should have been provided by default. There is an issue for this https://github.com/angular/angular.js/issues/8341

I had faced the similar problem.I looked into the angular lib and added a few lines to have status returned in the response itself.In this file,find where promise is being returned.

Replace code block starting with

var promise = $http(httpConfig).then(function(response)

with the following

var promise = $http(httpConfig).then(function(response) {
            var data = response.data,
                promise = value.$promise;

            if (data) {
              // Need to convert action.isArray to boolean in case it is undefined
              // jshint -W018
              if ( angular.isArray(data) !== (!!action.isArray) ) {
                throw $resourceMinErr('badcfg', 'Error in resource configuration. Expected ' +
                  'response to contain an {0} but got an {1}',
                  action.isArray?'array':'object', angular.isArray(data)?'array':'object');
              }
              // jshint +W018
              if (action.isArray) {
                value.length = 0;
                forEach(data, function(item) {
                  value.push(new Resource(item));
                });
              } else {
                copy(data, value);
                value.$promise = promise;
              }
            }

            value.status = response.status;
            value.$resolved = true;

            response.resource = value;

            return response;
          }, function(response) {
            value.status = response.status;
            value.$resolved = true;

            (error||noop)(response);

            return $q.reject(response);
          });

or you can add this line

value.status = response.status;

and then access status in code like reponse.status.Though,this is kind of hack but worked for me.I also had to make changes in the minified version.

I agreed responseHeaders() function will only return response's header,but you can custom it and it's useful anyway.

To solve you problem. With the following:($$service is my $resource instance.)

var serve = new $$service();
serve.id = "hello_wrongPath"; // wrong path,will return 404
serve.$get()
    .then(function (data) {
        console.log("~~~hi~~~");
        console.log(data);
        return data;
    })
    .catch(function (error) {
        console.log("~~~error~~~");
        console.log(error);
        console.log(error.status); // --> 404
        console.log(error.statusText); // --> "Not Found"
        console.log(error.config.timeout); // --> 5000
        console.log(error.config.method); // --> GET
        console.log(error.config.url); // --> request url
        console.log(error.headers("content-type"));// --> "text/plain"
        return error.$promise;
    })
    .finally(function(data){
        console.log("~~~finally~~~");
        console.log(data); // --> undefined
    });

In this way,u can only catch status,statusText,timeout,method,headers(same with responseHeaders) in ERROR response.

If you want to see response details in success response,I used a interceptor like this:

ng.module("baseInterceptor", [])
    .factory("baseInterceptor", ["$q", function ($q) {
        return {
            'request': function (config) {
                console.info(config);
                //set timeout for all request
                config.timeout = 5000;
                return config;
            },
            'requestError': function (rejection) {
                console.info(rejection);
                return $q.reject(rejection);
            },
            'response': function (response) {
                console.log("~~interceptor response success~~");
                console.log(response);
                console.log(response.status);
                console.log(response.config.url);
                return response;
            },
            'responseError': function (rejection) {
                console.log("~~interceptor response error~~");
                console.log(rejection);
                console.log(rejection.status);
                return $q.reject(rejection);
            }
        };
    }]);

and then add interceptor to module:

.config(["$httpProvider", function ($httpProvider) {
    $httpProvider.interceptors.push("baseInterceptor");
}])
