我在获取令牌后在facebook中请求用户详细信息。我收到了以下回复。 回复如下
"{\"id\":\"xxxxx\",\"name\":\"abcd\",\"first_name\":\"ab\",\"last_name\":\"cd\",
\"link\":\"http:\\/\\/www.facebook.com\\/profile.php?id=xxxxx\",\"quotes\":\"Life is a difficult game. You can win it only by retaining your birthright to be a person.\",\"gender\":\"female\",\"timezone\":5.5,\"locale\":\"en_US\",\"verified\":true,\"updated_time\":\"2012-02-22T12:59:39+0000\"}"
我打印的答案类显示为"String"
。我想把它改成哈希。
(我想删除上面的\。)
我试过但没有得到正确的格式。

那是JSON。你只需要解析它。
require 'json'
JSON.parse("{\"id\":\"xxxxx\",\"name\":\"abcd\",\"first_name\":\"ab\",\"last_name\":\"cd\",
\"link\":\"http:\\/\\/www.facebook.com\\/profile.php?id=xxxxx\",\"quotes\":\"Life is a difficult game. You can win it only by retaining your birthright to be a person.\",\"gender\":\"female\",\"timezone\":5.5,\"locale\":\"en_US\",\"verified\":true,\"updated_time\":\"2012-02-22T12:59:39+0000\"}")
#=> {"id"=>"xxxxx", "name"=>"abcd", "first_name"=>"ab", "last_name"=>"cd", "link"=>"http://www.facebook.com/profile.php?id=xxxxx", "quotes"=>"Life is a difficult game. You can win it only by retaining your birthright to be a person.", "gender"=>"female", "timezone"=>5.5, "locale"=>"en_US", "verified"=>true, "updated_time"=>"2012-02-22T12:59:39+0000"}

您获得的响应是JSON对象。将其解析为哈希的最简单方法是使用JSON gem。以下是字符串中前几个实体的示例。如您所见,它只返回一个哈希值。
ruby-1.9.3-rc1 :001 > require 'json'
=> true
ruby-1.9.3-rc1 :002 > JSON.parse("{\"id\":\"xxxxx\",\"name\":\"abcd\",\"first_name\":\"ab\"}")
=> {"id"=>"xxxxx", "name"=>"abcd", "first_name"=>"ab"}
