i know it's old question spent lot of time find example works in java post here solution i've done. used httpurlconnection insted of httpclient , httppost classes.
import java.io.bufferedreader; import java.io.dataoutputstream; import java.io.ioexception; import java.io.inputstreamreader; import java.net.httpurlconnection; import java.net.url; import java.nio.charset.standardcharsets; public class flightsjava { public static void main(string[] args) throws ioexception { string request = "http://partners.api.skyscanner.net/apiservices/pricing/v1.0/"; url url = new url( request ); httpurlconnection conn= (httpurlconnection) url.openconnection(); conn.setdooutput( true ); conn.setinstancefollowredirects( false ); conn.setrequestmethod( "post" ); conn.setrequestproperty( "content-type", "application/x-www-form-urlencoded"); conn.setrequestproperty("accept", "application/json"); conn.setrequestproperty( "charset", "utf-8"); string urlparameters = "apikey=your_api_key&country=br¤cy=brl&locale=pt-br&originplace=sdu&destinationplace=gru&outbounddate=2016-09-23&locationschema=iata&adults=1"; byte[] postdata = urlparameters.getbytes( standardcharsets.utf_8 ); int postdatalength = postdata.length; conn.setrequestproperty( "content-length", integer.tostring( postdatalength )); conn.setusecaches( false ); try{ dataoutputstream wr = new dataoutputstream(conn.getoutputstream()); wr.write(postdata); wr.flush(); wr.close(); int responsecode = conn.getresponsecode(); system.out.println("\nsending 'post' request url : " + url); system.out.println("post parameters : " + urlparameters); system.out.println("response code : " + responsecode); system.out.println("header fields : " + conn.getheaderfields()); } catch (exception e){ system.out.println(e); } } } remember change "your_api_key" apikey provided skyscanner.
hope helps anyone.
