我通过Facebook Graph API从页面获取Feed。最后给出了一个链接,以便检索Feed的下一页,如下所示(我删除了访问令牌):

   "paging": {
      "previous": "https://graph.facebook.com/v2.8/14408401557/feed?fields=from,message,link,created_time,type,name,id,comments.limit\u0025280\u002529.summary\u002528true\u002529,shares,reactions.limit\u0025280\u002529.summary\u002528true\u002529&limit=100&since=1483025111&access_token=XXX|XXX&__paging_token=enc_AdABZBt6ZC7DctahZAsXG9wOUghwu8tMLYo1ZAlMdLcVCwa8VqVjBEsZABFiLRSVlA96xTQzKkrnd2ALIlGrGLhZALSum7&__previous=1",
      "next": "https://graph.facebook.com/v2.8/14408401557/feed?fields=from,message,link,created_time,type,name,id,comments.limit\u0025280\u002529.summary\u002528true\u002529,shares,reactions.limit\u0025280\u002529.summary\u002528true\u002529&limit=100&access_token=XXX|XXX&__paging_token=enc_AdBOFdepWf3pcZBDLiV0r00WXJZA8qN7iYCZCzrwSoZCxYuKnHvXVUyCp35KCz4CW35p0gsmQV3Vzs5xKXe16QyCKMEN"

如果我尝试使用给定的网址,我会收到以下错误:

   "error": {
      "message": "Syntax error \"Expected \")\", got end of string\" at character 171: from,message,link,created_time,type,name,id,comments.limit(u0025280\\u002529.summary\\u002528true\\u002529,shares,reactions.limit\\u0025280\\u002529.summary\\u002528true\\u002529",
      "type": "OAuthException",
      "code": 2500,
      "fbtrace_id": "Dxf6QrEjBl6"
   }

有人知道为什么吗?

答案 0 :(得分:1)

它们似乎被编码为JSON的输出。但我的猜测是你在使用前没有解码它们。 e.g。

comments.limit \ u0025280 \ u002529.summary \ u002528true \ u002529

e.g。如果你手动更换它可以工作

comments.limit%280%29.summary%28true%29

有关字符串的JSON编码的说明,请参阅此答案https://stackoverflow.com/a/3020108/1542667,\ u0025只是'%'
