Facebook图:后游标出错

Question

当我在facebook图形api上发出get请求，用于页面搜索时，一切都很好。但是，当我使用after光标或单击'next‘字段时，我得到以下错误：

{
    "error": {
        "message": "An unknown error has occurred.",
        "type": "OAuthException",
        "code": 1,
        "fbtrace_id": "B4oyy5hYamh"
    }
}

直到昨天，一切都运行得很完美，但今天我发现了这个问题。

这是我的第一个请求：

https://graph.facebook.com/v2.10/search?access_token=*******&fields=about,paging&type=place&center=41.817557,12.446137&categories=["FOOD_BEVERAGE"]&distance=2000&limit=25

这是对下一页的请求：

https://graph.facebook.com/v2.10/search?access_token=*******&fields=about,paging&type=place&center=41.817557,12.446137&categories=["FOOD_BEVERAGE"]&distance=2000&limit=25&after=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

Answer 1

你的后缀看起来不正确，它应该是一个很短的代码。您是否粘贴了访问令牌？

此查询https://graph.facebook.com/search?q=food&type=page&limit=3&access_token=ACCESS_TOKEN返回

{
data: [
{
name: "Food Network",
id: "20534666726"
},
{
name: "FOODbible",
id: "996909263665350"
},
{
name: "Food",
id: "113109208703114"
}
],
paging: {
cursors: {
before: "MAZDZD",
after: "MgZDZD"
},
next: "https://graph.facebook.com/v2.5/search?access_token=ACCESSTOKEN&pretty=1&q=food&type=page&limit=3&after=MgZDZD"
}
}

因此，要获取下一个列表，我只需将After值(MgZDZD)附加到初始查询，以获取下一页结果。例如https://graph.facebook.com/search?q=food&type=page&limit=3&access_token=ACCESS_TOKEN&after=MgZDZD
