Hi. Could you try JSON.stringify(AAAA) instead of to toString?

Whenever we try to get a json object containing all the dataStore items, it returns an empty object.

This is the code which is run at pageload.


loadObjectList(): **void** {


console.log("BBBB" + **this**.appService.getNamespaces());

 

}

This method in the app.component.ts file references the getNamespaces function in the app.service.ts file

 


**private** serverUrl = '[https://play.dhis2.org/test/api/dataStore](https://play.dhis2.org/test/api/dataStore)';

**private** headers = **new** Headers({'Content-Type': 'application/json'});

 


getNamespaces(): **any**{

 


**var** AAAA;
AAAA = **this**.http.get(**this**.serverUrl, {headers: **this**.headers})
    .map(res => res.json());
console.log("AAAA: " + AAAA.toString());
**return** AAAA;

 

}

This method tries to contact the dhis2.org/test server to get the dataStore object.

I know that it exist, as the url ‘https://play.dhis2.org/test/api/dataStore’ gives

["METADATASTORE","social-media-video"]

This tells me that I should at least get something, but I don’t.

I also tried to add my client to the CORS whitelist, and tried different types of header, but nothing works.

I constantly get the response

app.service.ts:91 AAAA: [object Object]

app.component.ts:195 BBBB[object Object]

Hope you have an answer for this

Hey,

Not sure if you still need help with this but it looks like Angular2?

I believe that this.http.get returns an Observable, so you’ll need to subscribe to it. You might want to have a look at [1]
