public static void sendrequest(string method, string notifications) { string url = service_base_url + method; jsonobject requestobject = new jsonobject(); jsonarray notificationsarray =null; jsonobject mainrequest = new jsonobject(); seek { notificationsarray = new jsonarray(notifications); requestobject.put("notifications", notificationsarray); mainrequest.put("request", requestobject); } grab (jsonexception e1) { // todo auto-generated grab block e1.printstacktrace(); } httpurlconnection connection = null; seek { url server = new url(url); connection = (httpurlconnection) server.openconnection(); connection.setrequestmethod("post"); connection.setrequestproperty("content-type", "application/json"); connection.setdoinput(true); connection.setdooutput(true); dataoutputstream author = new dataoutputstream(connection.getoutputstream()); writer.writebytes(mainrequest.tostring()); writer.flush(); writer.close(); parseresponse(connection); } grab (exception e) { system.out.println("an error occurred: " + e.getmessage()); } { if (connection != null) { connection.disconnect(); } } }
