Question

我想登录用户的签到以及他签到的地方的类别。

我试图获取用户喜欢和他们的类别，这对我有用 - “/ me / likes？fields = category” 以下是回复的回复：

{
    "data": [{
        "name": "11 East Street Cafe",
        "category": "Restaurant/Cafe",
        "id": "94871278677"
    },{
        "name": "ABC DEF",
        "category": "Politician",
        "id": "177526890164"
    }],
    "paging": {
        "cursors": {
            "before": "NDkyMzg4OTc3NTYyMjk3",
            "after": "MTc3NTI2ODkwMTY0"
        }
    }
}

为了办理登机手续，我尝试了“/ me / feed？with = location＆amp; fields = place，story”并返回已签入的地点列表。它返回我：

    {
    "data": [{
        "place": {
            "id": "117586118328311",
            "name": "Carraba's",
            "location": {
                "city": "Ellicott City",
                "country": "United States",
                "latitude": 39.27153726574,
                "longitude": -76.800542073324,
                "state": "MD",
                "zip": "21043"
            }
        },
        "story": "ABC was at Carraba's.",
        "id": "1533836476934935_1546360939015822"
    }, {
        "place": {
            "id": "876737405718973",
            "name": "Chipotle Mexican Grill",
            "location": {
                "city": "Baltimore",
                "country": "United States",
                "latitude": 39.2866707,
                "longitude": -76.6196671,
                "state": "MD",
                "street": "300 W Pratt St",
                "zip": "21201"
            }
        },
        "story": "Aadya Extentia was at Chipotle Mexican Grill.",
        "id": "1533836476934935_1546360502349199"
    }],
    "paging": {
        "next": "https://graph.facebook.com/v2.5/1533836476934935/feed?fields=place,story&wi…WzlgXDpe8ZCV8kHWcO2aNxlARSpwIZByS9OWkU8VC3nj2E3VoiLkJNpy2ESOI1R7fHIOJQZDZD"
    }
}

但它不会返回签到位置的类别。即我想知道它是餐厅，博物馆还是体育馆等。

我该怎么办？感谢。

Answer 1

您可以使用Field Expansion执行此操作：

/me/feed?with=location&fields=place{name,category},story

编辑：看起来这只适用于API版本＆lt; = 2.4，但不再适用于v2.5。

编辑＃2：我提交了一份错误报告，询问是否故意删除，或者是否是错误。 https://developers.facebook.com/bugs/1550467468600884/

Answer 2

即使 Place 是 Page ，我也无法通过字段扩展成功检索category字段...

这可以通过批处理请求完成，方法是使用第一个查询的输出作为第二个查询的输入：

curl \
    -F 'access_token={USER_ACCESS_TOKEN}' \
    -F 'include_headers=false' \
    -F 'batch=[{ "method":"GET","name":"get-places","relative_url":"me/feed?with=location&fields=place{id,name,location},story&limit=100", "omit_response_on_success": false },{"method":"GET","relative_url":"?ids={result=get-places:$.data.*.place.id}&fields=id,name,category"}]' \
