selfLink doesn't behave correctly with Cross-site baseurls

[aarcro]

I'm serving my Angular app from localhost:8000, with django running a tastypie backend on localhost:8888. I'm simulating a mobile app, so I have no need or desire to have django server the angular app.

With a config like this:

RestangularProvider.setBaseUrl('http://localhost:8888/api/v1/');  // Following the bing example
RestangularProvider.setRestangularFields({
  selfLink: 'resource_uri'
});

and resoure_uri values, which look like: "/api/v1/object/id"

The generated path when trying to put is:
http://localhost:8888/api/v1//api/v1/object/id

Perhaps BaseUrl should be split to BasePath and BaseDomain?

Also, this doesn't work:

    var site_address = "http://localhost:8888";
    console.log('Put from here:' + site_address + obj.resource_uri);
    return obj.customPUT(site_address + obj.resource_uri);

the correct address is logged, but the customPUT still goes to localhost:8000 :(

Not the best way to submit a patch, I know, but I did this:

And this:

                  if (__this.config.isAbsoluteUrl(elemSelfLink)) {

                    elemUrl = elemSelfLink;                                                                                                                                                          
                  }                                                                                                                                                                                  

Hope that points you in the right direction. It seems to be working for me at the moment. Actually I can see that it would break elemSelfLink values that started with http://

Hey,

Answering by parts:

Also, this doesn't work:

var site_address = "http://localhost:8888";
console.log('Put from here:' + site_address + obj.resource_uri);
return obj.customPUT(site_address + obj.resource_uri);

the correct address is logged, but the customPUT still goes to localhost:8000 :(

If you need to do a put to a custom URL, you should use oneUrl or allUrl. Something like Restangular.oneUrl('people', 'http://locahost:8888/people/name/123').customPUT(objectToPut). However, if it's going to locallhost, you should use "normal" Restangular behaviour.

and resoure_uri values, which look like: "/api/v1/object/id"

The generated path when trying to put is:
http://localhost:8888/api/v1//api/v1/object/id

Perhaps BaseUrl should be split to BasePath and BaseDomain?

Does this happen with the latest version of Restangular? I've fixed some problems with self linking elements in version 1.2.2. If that's not working, I'll mark this as a bug and check it out.

Thanks!

Hi @mgonto,
Thanks for all your work on restangular.

I'm running into similar behavior.

Configuration:

RestangularProvider.setBaseUrl("http://localhost:3000")

RestangularProvider.setSelfLinkAbsoluteUrl("http://localhost:3000")

RestangularProvider.setRestangularFields
  selfLink: '_links.self.href' # HAL self link

When trying to retrieve posts from a user it fails to honour the baseUrl.
The path is correct though, looking like the selfLink is behaving correctly.

The request goes to the nodejs server that is serving my app, instead of the api server.

Restangular.all("users").getList().then (users) ->
  user = users[0]
  user.all("posts").getList().then (posts) ->
    $scope.posts = posts

I can make it work by commenting out https://github.com/mgonto/restangular/blob/master/src/restangular.js#L27 and changing
https://github.com/mgonto/restangular/blob/master/src/restangular.js#L645
to

return __this.config.absoluteUrl+elemSelfLink;

Cheers

This issue shouldn't be closed. It still exists in 1.3.1 and based on the release notes, the behaviour hasn't changed in 1.4.0.

I'm currently circumventing this the "hard way" in a responseInterceptor:

angular.module('myapp').run([
  'Restangular',
  function(Restangular) {
    'use strict';

    // Workaround for https://github.com/mgonto/restangular/issues/493
    // Part 1: Figure out the protocol, host and port of the base url
    var parser = document.createElement('a');
    parser.href = Restangular.configuration.baseUrl;
    var baseUrl = parser.protocol + '//' + parser.host;

    Restangular.addResponseInterceptor(function(data, operation, what, url, response, deferred) {
      if (operation === "getList") {
        // Workaround for https://github.com/mgonto/restangular/issues/493
        // Part 2: Update selfLinks to have the full URL with the host
        if (data.length && data[0].href) {
          data.forEach(function(item) {
            if (item.href && item.href[0] === '/') {
              item.href = baseUrl + item.href;
            }
          });
        }
      }

      return data;
    });
  }
]);

I have the same problem with this where the baseURL is ignored for self links.

Additionally I am getting an issue when the links include a format suffix such as /resource/id.json then a call to a sub resources is calling /resource/id.json/subresource instead of /resource/id/subresource.json.

Can the RequestSuffix be taking into account for the self links?

[scottmcdonnell]

Added pull request #785 as a suggestion to fix the above issues.

[RemoteCTO]

+1 for this. I've also used the dirty patch as in #493 (comment) in the meantime.

[cstephe]

I use delete Restangular.configuration.absoluteUrl; as a work around

This issue has been a long time wait (from 2013) and gaining PR in multiple issues. It would be great to increase the priority. Thanks

[daviesgeek]

If I'm understanding this correctly, this is addressed in #851?
