Ruby on rails Rails通过输出json并尝试将其作为方法调用来响应_

我创建了一个用json响应的简单api。当我尝试从浏览器调用它时，我会得到相应的json响应，但当我尝试从actionscript远程调用它时，它似乎试图调用json，就好像它是一个方法一样。这是控制器操作：

  def matcher
    @conn = Connection.first
    if(@conn)
      respond_with({:conn => @conn, :status => :ok}.to_json)
    else
      respond_with({:status => :no_content}.to_json)
    end
  end

这是服务器收到呼叫时的响应

谢谢

我很好奇为什么它能在浏览器中工作。我预计它在那里也会失败。 使用以下命令检查响应单元的源：

def respond_with(*resources, &block)
  raise "In order to use respond_with, first you need to declare the formats your " <<
        "controller responds to in the class level" if self.class.mimes_for_respond_to.empty?

  if response = retrieve_response_from_mimes(&block)
    options = resources.extract_options!
    options.merge!(:default_response => response)
    (options.delete(:responder) || self.class.responder).call(self, resources, options)
  end
end

respond_with是一个响应程序，它将对象作为参数，而不是json。它根据操作确定适当的响应

如果您想呈现自己的json，可以使用respond_to.

也可以发布js代码吗？我没有js代码。调用方处于actionscriptUPDATE中：只有在POST no GETT的情况下才会发生上述链接现在已失效。是github上的后期归档。

def respond_with(*resources, &block)
  raise "In order to use respond_with, first you need to declare the formats your " <<
        "controller responds to in the class level" if self.class.mimes_for_respond_to.empty?

  if response = retrieve_response_from_mimes(&block)
    options = resources.extract_options!
    options.merge!(:default_response => response)
    (options.delete(:responder) || self.class.responder).call(self, resources, options)
  end
end

respond_to do |format|
  format.html # some.html.erb
  format.json  { render :json => {:conn => @conn, :status => :ok}.to_json }
end
