Yii框架如何统一URL地址？

//参考代码示例

$.ajax({

            type:"post",

            url:"<?php echo yii\helpers\Url::toRoute(['controllername/actionname']) ?>",

            data:{'params':params, 'params':params, 'params':params},

            dataType:"json",

            success:function(message){

                if(message.status == "success"){

                    window.location.href = "<?php echo yii\helpers\Url::toRoute(['controllername/actionname','id'=>$id]) ?>;

                }else{

                    alert(message.error_message);

                }

            }

        });
