出于某种原因,当使用json或xml向我的应用程序发出请求时,我得到一个InvalidAuthenticityToken.我的理解是rails应该只为html或js请求提供真实性令牌,因此我不应该遇到这个错误.到目前为止,我发现的唯一解决方案是禁用protect_from_forgery来执行我想通过API访问的任何操作,但由于显而易见的原因,这并不理想.思考？

    def create
    respond_to do |format|
        format.html
        format.json{
            render :json => Object.create(:user => @current_user, :foo => params[:foo], :bar => params[:bar])
        }
        format.xml{
            render :xml => Object.create(:user => @current_user, :foo => params[:foo], :bar => params[:bar])
        }
    end
end

每当我将请求传递给操作时,这就是我在日志中获得的内容:

 Processing FooController#create to json (for 127.0.0.1 at 2009-08-07 11:52:33) [POST]

它不仅可以在HTML中填写表单,还可以发送包含参数的发布请求.例如,如果将Accept标志设置为'application/JSON',是否可以关闭真实性标记在HTTP标头？
