编写json

{
    "data": [
        {
            "name": "向某"
        },
        {
            "name": "罗某"
        },
        {
            "name": "张某"
        },
        {
            "name": "王某"
        },
        {
            "name": "周某"
        },
        {
            "name": "李某"
        }
    ]
}

提示，这个要放在服务器里边去跑，不然后要报跨域异常
