Hi Tim, Sure this is possible (with the latest Zn of course): ZnClient new forJsonREST; url: 'http://climatedataapi.worldbank.org/climateweb/rest/v1/country/annualavg/pr'; addPath: { '20190101'. '20191231'. #bel }; get. I do not know how to use this API to get actual data, but the above succeeds with an empty JSON result. If you study #forJsonREST you should be able to figure out how this is done. Here is another example (from the unit tests): ZnClient new forJsonREST; url: 'http://easy.t3-platform.net/rest/geo-ip'; queryAt: 'address' put: '81.83.7.35'; get. And a very simple one: ZnClient new forJsonREST; get: 'https://api.ipify.org?format=json'. Note that the result depends a bit on whether NeoJSON is loaded or not (the fallback is to use STONJSON which is always present in the image). HTH, Sven

Hi everyone, I’m finally finding some space from world chaos and looking more into Pharo, and I have a question about retrieving json data from feeds - how is the best way to elegantly parse it - e.g.

I am doing :

url := ZnUrl fromString: 'http://climatedataapi.worldbank.org/climateweb/rest/v1/country/annualavg/pr’. url addPathSegments: {aDate1 asString. aDate2 asString. aCountryCode}. result := ZnEasy get: url. content := STONJSON fromString: result contents. ...

However I was kind of surprised there wasn't something on a ZnResponse for getting json objects e.g. result getJsonObjects

or something like that?

It’s so common I wonder if I am missing some trick? What aren’t there helpers in place for this or is there a better way to do this that I haven’t found yet?

I was kind of thinking something like (which obviously I can add myself)

result asJsonObjects sum: [:obj | (obj at: ‘annualData’) first ]
