Question

我正在从API JSON响应索引，如下所示：

[{
    "id": 1
    "name": "Gimbal HQ",
    "addressLineOne": "5775 Morehouse Drive, San Diego CA 92121",
    "geoFenceCircle": {
        "radius": 100,
        "visibility": "ORGANIZATION",
        "location": {
            "latitude": 32.89494374592149,
            "longitude": -117.19603832579497
        }
    },
    "placeAttributes": {
        "key1": "value1",
        "key2": "value2"
    }
},
{
    "id": 3291
    "name": "Gimbal R&D",
    "addressLineOne": "5665 Morehouse Drive, San Diego CA 92121",
    "geoFencePolygon": {
        "visibility": "ORGANIZATION",
        "locations": [
            {
                "latitude": 32.8953153522896,
                "longitude": -117.19559844351653
            },
            {
                "latitude": 32.8954009341414,
                "longitude": -117.19516929007415
            },
            {
                "latitude": 32.89564867061472,
                "longitude": -117.1949815354431
            },
            {
                "latitude": 32.89545949009762,
                "longitude": -117.19463284827117
            },
            {
                "latitude": 32.894986537037255,
                "longitude": -117.19496544218902
            },
            {
                "latitude": 32.894864920127866,
                "longitude": -117.19554479933623
            }
        ]
    },
    "placeAttributes": {
        "key1": "value1",
        "key2": "value2"
    }
}]

这一切都很好，花花公子。但我的问题是我的代码，特别是这一行：

for geofence in geofences:
        obj, created = Geofence.objects.get_or_create(name=geofence['name'])

我似乎提出了以下错误：

21:17:17 web.1  |     obj, created = Geofence.objects.get_or_create(name=geofence['name'])
21:17:17 web.1  | TypeError: string indices must be integers

我无法弄清问题是什么，有人可以对此有所了解吗？

Answer 1

最好检查地理围栏对象数据类型。

它看起来像是一个数组而不是地图。

Answer 2

我认为您需要在名称索引前面放置一个索引。尝试：

obj, created = Geofence.objects.get_or_create(name=geofence[0]['name'])

Answer 3

您的JSON格式的字符串数据已损坏（每个,键后id缺少两次）：

[{
"id" : 1
"name" : "Gimbal HQ",
"addressLineOne" : "5775 Morehouse Drive, San Diego CA 92121"
}]

Answer 4

我认为您正在将dict访问到列表中。

for geofence in geofences:
        obj, created = Geofence.objects.get_or_create(name=geofence[geofence].get('name'))

这里['geofence']指的是for循环的索引，它将选择列表对象并访问dict对象，你可以在python中编写get()方法。这样做的主要好处是它将永远回归。

JSON索引TypeError：字符串索引必须是整数
