       const message = {
            "data": {

                "offerid": offerid,

		};
		
		$.ajax({

            type:'post',
            url: baseurl+'/ali-receive',
            data:"message="+json.stringify(message)
        });
		

   @postmapping("/ali-receive")
    public void alireceive(@requestparam("message") string message) {
                receivelog receivelog = json.parseobject(message, receivelog.class);
