webread POST query behavior changed between MATLAB R2016b and R2017a

Hello all,

I updated recently to MATLAB R2017a and the behavior of the webread function seems to have changed. I'm trying to get data from a web service using a POST query:

url = 'https://estadisticas.bcrp.gob.pe/estadisticas/series/api/';
options = weboptions('RequestMethod','post','CertificateFilename','');
start_str = '2003-1';
end_str = '2017-2';
series = 'PN00181MM';
webread(url,'series',series,'fechaini',start_str,'fechafin',end_str,'idioma','ing','formato','txt',options);

This works fine in MATLAB R2016b, returning time series data... but MATLAB R2017a seems to be returning a txt version of the webpage found at the url.

I would like to know how to obtain the previous behavior using MATLAB R2017a.

All help would be appreciated!

Best,

Hugo.

It is recommended to use 'webwrite' instead of 'webread'. For example,

options = weboptions('CertificateFilename','');
webwrite(url,'series',series,'fechaini',start_str,'fechafin',end_str,'idioma','ing','formato','txt',options);

For more information on webwrite take a look into the following link webwrite.
