Using Http with map to get json response doesn't seem to work

[eesdil]

Trying to use http module from angular2 in nativescript, but I am getting this error:

file:///app/tns_modules/angular2/src/platform/serv
er/parse5_adapter.js:55:75: EXCEPTION: TypeError: _this.http.request(address, options)
                            .map is not a function. (In '_this.http.request(address, options)

This is working in the browser and also including in both places the rxjs map module

import 'rxjs/add/operator/map';

If I remove this from the browser I am getting the same message. But with nativescript even if I add it, it doesnt work...

What can be wrong here? Is there any working example using the http module?

Posted here, but so far no ideas, so adding it here as well

@eesdil, I had an early experiment with the http module, but then the API changed and I never updated it.

What example are you trying to port from the browser version? Could you post a repro project that I can run locally?

Thanks. It Would be too complicated to share and use it probably. I will create a repo bit later to be able to check it.

Hmm. I created one, but yet there is no backend to connect and it doesn't start :)... but you can see the code at least for now.

Seems like it started. I got "Service exited due to signal: Killed: 9" and started to debug it and it started to work... clicking on login in the app it also raised the error what i expected.

I got it running here. I had to add the typescript hooks and some of the compat d.ts files (the commit before that), but nothing more. I wonder if the problem occurs just for certain types of requests or parameters.

Thank you. I am checking it. It can happen that I am not getting back result (wrong ip address, as localhost cannot be accessed in the emulator), thats why it fails. But I am getting a bit frustrated as it takes 10 minutes to start the debugger. And Without debugger I just get immediate crash.

With the default android emulator it is a nightmare..., but using the genymotion it is working pretty well. So the http (map, etc) working fine in android, tried in linux and osx.

But in ios emulator I have the same error using the same code:

.js:79:28: JS ERROR EXCEPTION: Error during evaluation of "tap"
        ORIGINAL EXCEPTION: TypeError: this.http.request(address)
                    .map is not a function. (In 'this.http.request(address)
                    .map(function (res) { return res.json(); })', 'this.http.request(address)
                    .map' is undefined)

Didnt write yesterday, but even this is working in android, in the subscribe function I am getting string instead of json. Strangely if I remove the map function, I am not getting the result (just the headers) in the subscribe function.

This looks like a bug in the iOS require implementation. I'll update this issue when I know more.

@eesdil
Can you please confirm that the issue is resolved with the latest(0.0.36) release of nativescript-angular.
I have tested it with the sample-ng-http project and everything seems to work fine.

[eesdil]

Thanks. I will check it and let you know.

@eesdil I'm closing the issue - please reopen it if the problem reoccurs.
