请问gin框架如何接受二维数组map？

比如在php里有这样的二维关联数组：

$where_in = [
    'id' => [1,2,34],
    'state' => [35,6,7,8],
];

$where = [
    'age' => 18,
    'sex' => 1,
];

$type = [
    1,
    2,
];  
$params = [
    'name' => '张三',
    'where' => $where,
    'where_in' => $where_in,
    'type' => $type,
];

如何通过get接收参数传递？

url是这样的：
http://192.168.3.107:8000/item?name=张三&where[age]=18&where[sex]=1&where_in[id][0]=1&where_in[id][1]=2&where_in[id][2]=34&where_in[state][0]=35&where_in[state][1]=6&where_in[state][2]=7&where_in[state][3]=8&type[0]=1&type[1]=2

如果通过c.Request.URL.Query() 去接收，返回的是一个 k v类型的map，无法合并
