When I go to this url in by browser, it shows me the json feed i expect:

https://www.facebook.com/feeds/page.php?format=json&id=237173582992285

When in PHP I do a 

<?php
print_r(file_get_contents('https://www.facebook.com/feeds/page.php?format=json&id=237173582992285'));
?>

I get an html page saying my browser is not supported by facebook and that I should upgrade. How do I make the file_get_contents return the json feed I'm expecting?

Additional Notes I also tried from bash wget https://www.facebook.com/feeds/page.php?format=json&id=237173582992285 and the file I downloaded also has html content saying browser not supported.

试试这个，它对我有用

 $ch = curl_init("https://www.facebook.com/feeds/page.php?format=json&id=237173582992285");
  curl_setopt( $ch, CURLOPT_POST, false );
  curl_setopt( $ch, CURLOPT_FOLLOWLOCATION, true );
  curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.7.12) Gecko/20050915 Firefox/1.0.7");
  curl_setopt( $ch, CURLOPT_HEADER, false );
  curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );
  $data = curl_exec( $ch );
  echo $data;

正如@Michael Mior 所指出的，它违反了Facebook 条款。但这是您问题的答案，facebook 有一个简单的检查来确保页面应该由浏览器打开，因此我们通过设置useragent标题来模仿它。

您应该改用 Facebook API。Graph API Explorer以及Pages API上的文档应该可以帮助您入门。

提要供 RSS 阅读器使用，而不是供脚本使用。理论上你可以通过更改User-Agent标题来解决这个问题，但这违反了 Facebook 的服务条款

要获取页面的公开帖子，您应该使用其相应的连接，即feed与任何有效的连接access_token。

因此，要获取您提到的页面的公共提要，请使用/237173582992285/feed. 此外，您可以选择仅获取您需要的数据，例如/237173582992285?fields=feed.fields(message,type,status_type) 会产生如下结果： 

{
  "id": "237173582992285",
  "feed": {
    "data": [
      {
        "message": "???? ???? ???? :) - ??? <3",
        "type": "photo",
        "status_type": "added_photos",
        "id": "237173582992285_461226513920323",
        "created_time": "2012-11-03T12:46:20+0000"
      },
      {
        "message": "?????? ????? ? ???? ???? ????? ?? ??????? ? ????? ???? ??????? ????? ???? ???????? ????????? :D :D :D - ??? <3",
        "type": "photo",
        "status_type": "added_photos",
        "id": "237173582992285_457876184255356",
        "created_time": "2012-10-26T09:43:01+0000"
      }, 
      ....etc
    ],
    "paging": {
      "previous": "https://graph.facebook.com/237173582992285/feed?fields=message,type,status_type&limit=25&since=1351946780",
      "next": "https://graph.facebook.com/237173582992285/feed?fields=message,type,status_type&limit=25&until=1348763989"
    }
  }
}
