Php Yii cgui自动完成动态源URL。如何？

情况：

带有“国家”下拉列表、“邮政编码”文本字段、“城市”文本字段的表单

国家下拉列表有两项：比利时和法国（有效值分别为BE和FR）

“PostalCode”字段是CJuiAutoComplete字段，根据从国家/地区下拉列表中选择的值，它必须从“BeCity/getBelgianPostalCodes”或“FrCity/getFrenchPostalCodes”获取自动完成数据

这两个操作相互独立，工作完美，它们生成正确的自动完成数据。但是，我无法理解如何根据国家/地区下拉列表的选定值使其动态工作。我尝试将所选国家/地区置于会话状态，并从中动态生成sourceUrl。当我查看生成的html的源代码时，根据所选的国家/地区，生成的sourceUrl是正确的，但我仍然从加载的第一个国家/地区获取值。那么大概是缓存问题还是什么

代码如下：

            echo CJSON::encode($res);
            Yii::app()->end();
        }

这是使用会话变量的正确方法，还是有更好的方法

那么缓存问题呢

感谢您的帮助

Ok，我们可以通过一个操作（函数）获取country参数，并执行该操作中的所有逻辑，而不是尝试重新路由到两个单独的操作：
