您可以使用json库 json

You can use the json library json

您可以执行以下操作:

jsonArray = [{"content":"1D","createdTime":"09-06-2011 00:59"},   
              {"content":"2D","createdtime":"09-06-2011 08:00"}]
objArray = JSON.parse(jsonArray)

只要您的JSON适合您的模型，就可以对您的评论做出回应

In response to your comment, you can do this, as long as your JSON fits your model

objArray.each do |object|
  # This is a hash object so now create a new one.
  newMyObject = MyObject.new(object)
  newMyObject.save # You can do validation or any other processing around here.
end
