如何在Rails 3.1中初始化ActionDispatch :: ParamsParser? [英] How do I initialize ActionDispatch::ParamsParser in Rails 3.1?

问题描述

我的应用程序为其Rest接口定义了一个自定义Mime类型.所以我在mime_types.rb初始化程序中注册了它:

My application defines a custom Mime type for its Rest interface. So I register it in the mime_types.rb initializer:

Mime::Type.register "application/vnd.example.app-v1+xml", :xml_v1

并且Rails可以正确处理控制器中的respond_to块.

and Rails correctly handles the respond_to blocks in the controllers.

但是，我仍然需要告诉Rails使用ActionDispatch :: ParamsParser将传入的请求解析为XML.我只是不知道如何在初始化程序中使用它.正确的方法是什么?

However, I still need to tell Rails that incoming requests should be parsed as an XML, using ActionDispatch::ParamsParser. I just don't know how to use it inside an initializer. What's the correct way?

推荐答案

效果很好:

Mime::Type.register "application/vnd.example.app-v1+xml", :xml_v1

MyRailsApp::Application.config.middleware.delete "ActionDispatch::ParamsParser"
MyRailsApp::Application.config.middleware.use ActionDispatch::ParamsParser, { Mime::XML_V1 => :xml_simple }
