Question

我想使用facebook FQL从页面流中提取帖子的图片网址，我能够得到以下内容，但是我更愿意只获得正常尺寸图片的链接，然后我计划使用java提取链接，但我想先简化结果。

FQL：

SELECT attachment   FROM stream WHERE source_id = 187050104663230  AND type = 247 AND created_time > 1383293228 LIMIT 1

上述结果：

{
  "data": [
    {
      "attachment": {
        "media": [
          {
            "href": "https://www.facebook.com/photo.php?fbid=699393523428883&set=a.190470824321158.46817.187050104663230&type=1&relevant_count=1",

尽可能缩小范围。

代码：

SELECT attachment.media.photo.images.src   FROM stream WHERE source_id = 187050104663230  AND type = 247 AND created_time > 1383293228 LIMIT 1

结果：

{
  "data": [
    {
      "attachment": {
        "media": [
          {
            "photo": {
              "images": [
                {
                  "src": "https://fbcdn-photos-h-a.akamaihd.net/hphotos-ak-prn2/1508634_699393523428883_996610253_s.png"
                },
                {
                  "src": "https://fbcdn-sphotos-h-a.akamaihd.net/hphotos-ak-prn2/s720x720/1508634_699393523428883_996610253_n.png"
                }
              ]
            }
          }
        ]
      }
    }
  ]
}
