getString返回的数组中包含NULL时，该键都不返回

当json为如下时：{ `{ "payType": 2, "payer": "-", "payAmount": "2602", "chargeInfos": [{

        "test": 1,

    }, {
        "test": null,

    }, {
        "test": null,

    }, {
        "test": null,

    }, {
        "test": null,
    }
]

}` 此时getString("chargeInfos") 打印出来的是[{"test":1},{},{},{},{}]，null都不返回
