推荐答案
您有一个名为将负责处理请求
You have a method called respond_to which will take care of the requests
def index
@people = Person.find(:all)
respond_to do |format|
format.html
format.xml { render :xml => @people.to_xml }
format.json {render :json => @people.to_json}
end
end
控制器中的上述方法将根据请求格式回复
The above method in controller will respond according to the request format
