JSON 语法问题

Question

我对JSON不太熟悉，主要是PHP。当我运行查询 Mapquest 地理编码 API 时，我得到以下 json 字符串，在 PHP 中尝试 json_decode 它变成 "NULL" ].

renderOptions({
    "info": {
        "statuscode": 0,
        "copyright": {
            "text": "\u00A9 2016 MapQuest, Inc.",
            "imageUrl": "https://api.mqcdn.com/res/mqlogo.gif",
            "imageAltText": "\u00A9 2016 MapQuest, Inc."
        },
        "messages": []
    },
    "options": {
        "maxResults": -1,
        "thumbMaps": true,
        "ignoreLatLngInput": false
    },
    "results": [{
        "providedLocation": {
            "street": "Kingston Upon Thames,uk"
        },
        "locations": [{
            "street": "",
            "unknownInput": "",
            "type": "s",
            "latLng": {
                "lat": 51.409628,
                "lng": -0.306262
            },
            "displayLatLng": {
                "lat": 51.409628,
                "lng": -0.306262
            },
            "mapUrl": "https://open.mapquestapi.com/staticmap/v4/getmap?key=na&type=map&size=225,160&pois=purple-1,51.4096275,-0.3062621,0,0,|¢er=51.4096275,-0.3062621&zoom=12&rand=54353"
        }]
    }]
})

运行通过 JSONLint，我得到以下错误：

Error: Parse error on line 1: renderOptions({ "in ^ Expecting 'STRING', 'NUMBER', 'NULL', 'TRUE', 'FALSE', '{', '[', got 'undefined'

我认为修复非常简单，但我不太了解 JSON 语法，所以我一直在摸索着把东西放在 'renderOptions'.[=13= 之前]

解决问题的正确语法是什么？

Answer 1

这将是一个有效的 json

{
    "renderOptions": {
        "info": {
            "statuscode": 0,
            "copyright": {
                "text": "\u00A9 2016 MapQuest, Inc.",
                "imageUrl": "https://api.mqcdn.com/res/mqlogo.gif",
                "imageAltText": "\u00A9 2016 MapQuest, Inc."
            },
            "messages": []
        },
        "options": {
            "maxResults": -1,
            "thumbMaps": true,
            "ignoreLatLngInput": false
        },
        "results": [{
            "providedLocation": {
                "street": "Kingston Upon Thames,uk"
            },
            "locations": [{
                "street": "",
                "unknownInput": "",
                "type": "s",
                "latLng": {
                    "lat": 51.409628,
                    "lng": -0.306262
                },
                "displayLatLng": {
                    "lat": 51.409628,
                    "lng": -0.306262
                },
                "mapUrl": "https://open.mapquestapi.com/staticmap/v4/getmap?key=na&type=map&size=225,160&pois=purple-1,51.4096275,-0.3062621,0,0,|¢er=51.4096275,-0.3062621&zoom=12&rand=54353"
            }]
        }]
    }
}

Answer 2

删除 renderOptions()，括号内的内容是 JSON，从第一个卷曲开始到最后一个卷曲结束。

Answer 3

在您的 URL 到 mapquest 地理编码服务中，您将有一个参数 "callback=renderOptions" - 可能是从示例中复制和粘贴的。删除该参数以删除回调包装。
