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
