How do I get the HTTP response status code in Angu

问题:

Using ngResource in AngularJS 1.2rc(x), how do I get the status code now?

RestAPI.save({resource}, {data}, function( response, responseHeaders ) {
});

where RestAPI is my ngResource.

The response has the $promise object and the resource returned from the server but not a status anymore. The responseHeaders() function only has a status if the server injects the status code into the header object, but not the true returned status code. So some servers may serve it and some might not.

回答1:

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

回答3:

For anyone using a newer version of Angular, looks like we've had access to the status code as a 3rd param to the transformResponse function since angular 1.3, but it was never documented properly in the $resource docs.

回答4:

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");
}])

You can get response status like this:

$http.get(url).then(function(response){
  console.log(response.status); //successful status like OK
}, function(response){
  console.log(response.status); //error status like 400-Bad Request
})

回答6:

I'm using AngularJS v1.5.6, and I do it like this (in my case I put the "getData" method inside a service):

function getData(url) {
    return $q(function (resolve, reject) {
        $http.get(url).then(success, error);

        function success(response) {
            resolve(response);
        }
        function error(err) {
            reject(err);
        }
    });
}

then in the controller (for example), call that like this:

function sendGetRequest() {
    var promise = service.getData("someUrlGetService");
    promise.then(function(response) {
        //do something with the response data
        console.log(response.data);
    }, function(response) {
        //do something with the error
        console.log('Error status: ' + response.status);
    });
}

As documentation says, the response object has these properties:

• data – {string|Object} – The response body transformed with the transform functions.
• status – {number} – HTTP status code of the response.
• headers – {function([headerName])} – Header getter function.
• config – {Object} – The configuration object that was used to generate the request.
• statusText – {string} – HTTP status text of the response.

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

Hope it helps!

I think the right answer is a combination of Bardiel's and Ara's answers.

After adding 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;
            }
        }
    }                            
});

Use it as below:

RestAPI.save()
.query(function(response) {
    // This will return status code from API like 200, 201 etc
    console.log(response.$status);
})
.$promise.catch(function(response) {
    // This will return status code from server side like 404, 500 etc
    console.log(response.status);
});

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.
