Laravel8.x中Session使用简单记录

为了方便记录，Session的操作就routes/web.php路由文件中完成。

以上操作均在web.php路由中完成

使用Request实例操作session

存储session

put-存储session

push第一个参数，一直点下去将，点后的名称都会变是多维数组的键：

如push(a.a1.a2,'wangwu')

解释：数组a下面有一个key为a1的数组，a1下面有一个key为a2的数组，a2数组下有个key为0键，其对应的值为wangyu。

push可以追加元素进数组

更新session

覆盖已有session的值就是更新
