删除字符串中的斜杠

Question

我在获得令牌后在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\"}"

我打印出的答案类显示为"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.

Answer 1

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"}
