这个JSON有什么问题

Question

我必须将此JSON格式作为post请求发送到api。但是当在JSONLint上在线检查时，它说错了，错误。请指导创建正确。以下是JSON格式：

{
"departure_time" = "2017-07-28T17:39:43.611Z";
steps = ({
    "encoded_polyline" = "ytfzDqzksM_AgB";
    "road_name" = "ytfzDqzksM_AgB";
}, {
    "encoded_polyline" = "yvfzDy}ksMPMf@a@";
    "road_name" = "yvfzDy}ksMPMf@a@";
}, {
    "encoded_polyline" = "_ufzDi_lsM}@mB";
    "road_name" = "_ufzDi_lsM}@mB";
}, {
    "encoded_polyline" = "}vfzDwblsMb@a@f@a@";
    "road_name" = "}vfzDwblsMb@a@f@a@";
}, {
    "encoded_polyline" = "qtfzD{dlsMoA}B";
    "road_name" = "qtfzD{dlsMoA}B";
});
vehicle = {
    axles = 2;
};
}

请指导其中的错误以及如何纠正错误。

验证的JSON

{
    "departure_time": "2017-07-28T17:39:43.611Z",
    "steps": [{
        "encoded_polyline": "ytfzDqzksM_AgB",
        "road_name": "ytfzDqzksM_AgB"
    }, {
        "encoded_polyline": "yvfzDy}ksMPMf@a@",
        "road_name": "yvfzDy}ksMPMf@a@"
    }, {
        "encoded_polyline": "_ufzDi_lsM}@mB",
        "road_name": "_ufzDi_lsM}@mB"
    }, {
        "encoded_polyline": "}vfzDwblsMb@a@f@a@",
        "road_name": "}vfzDwblsMb@a@f@a@"
    }, {
        "encoded_polyline": "qtfzD{dlsMoA}B",
        "road_name": "qtfzD{dlsMoA}B"
    }],
    "vehicle": {
        "axles": 2
    }
}

首先，分号必须用逗号替换分隔行，除了最后一行不需要任何东西：

"encoded_polyline" = "qtfzD{dlsMoA}B",
"road_name" = "qtfzD{dlsMoA}B"

要声明一个数组，请使用括号，而不是括号：

"steps" = [{
    "encoded_polyline" = "ytfzDqzksM_AgB";
    "road_name" = "ytfzDqzksM_AgB";
}, {
    "encoded_polyline" = "yvfzDy}ksMPMf@a@";
    "road_name = "yvfzDy}ksMPMf@a@";
}]

最后，在JSON中不使用等号符号。相反，使用冒号：

"departure_time" : "2017-07-28T17:39:43.611Z"
