问题遇到的现象和发生背景

json如何再往field_values中添加一个对象 {
"field_uuid": "field001",
"type": 2,
"value": "1"
}

问题相关代码，请勿粘贴截图

{
"tasks": [{
"priority": "1",
"total_manhour": 0,
"estimate_variance": null,
"time_progress": 0,
"attribute": null,
"field_values": [
{
"field_uuid": "field001",
"type": 2,
"value": "1"
}
],
"add_manhours": [],
"watchers": ["1", "1"]
}]
}

瞅瞅行不行

先把json 转成对象 再往对象里面添加有一值 再转json
这种方式最简单了

这样


{
    "tasks": [
        {
            "attribute": null,
            "priority": 14,
            "watchers": [
                75,
                74,
                56
            ],
            "time_progress": 1360003243228,
            "field_values": {
                "two": {
                    "id": 76,
                    "name": 12
                },
                "one": {
                    "field_uuid": null,
                    "type": 1
                }
            },
            "add_manhours": [
                null
            ],
            "estimate_variance": null,
            "total_manhour": 61
        }
    ]
}
