1、定义structGVariant{/*Noavailablefields*/}GVariant是一个变量数据类型；它可以包含一个或多个值以及有关值类型的信息。2、实例方法constgchar**g_variant_get_strv(GVariant*value,gsize*length)获取GVariant字符数组内容。这个方法会做一个浅拷

GVariantFormatStrings类型字符串实例分析(sa{sv}as)外层是元组类型，内含三个成员，分别是字符串s字典类型数组a{sv}，字符串作为key，variant作为value字符串类型数组as(i@ii)外层是元组类型，内含三个成员，分别是gint类型数字类型ivariant类型@i，对应数字
