Rails路由匹配查询参数

本文介绍了Rails路由匹配查询参数的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

轨道路由非常适合匹配RESTful样式的URL的'/'分隔位，但是我可以匹配 map.connect 配置。我希望根据’？

Rails routes are great for matching RESTful style '/' separated bits of a URL, but can I match query parameters in a map.connect config. I want different controllers/actions to be invoked depending on the presence of a parameter after the '?'.

我正在尝试类似的操作...

I was trying something like this...

map.connect "api/my/path?apple=:applecode", :controller => 'apples_controller', :action => 'my_action' map.connect "api/my/path?banana=:bananacode", :controller => 'bananas_controller', :action => 'my_action'

出于路由目的，我并不关心参数的值，只要它可以在 params 哈希

For routing purposes I don't care about the value of the parameter, as long as it is available to the controller in the params hash

推荐答案

解决方案基于从外部进入的路线（Rails）的高级约束部分（guides.rubyonrails/routing.html）。

The following solution is based on the "Advanced Constraints" section of the "Rails Routing from the Outside In" rails guide (guides.rubyonrails/routing.html).

在您的config / routes.rb文件中，包括识别器类是否具有匹配项？方法，例如：

In your config/routes.rb file, include a recognizer class have a matches? method, e.g.:

class FruitRecognizer def initialize(fruit_type) @fruit_type = fruit_type.to_sym end def matches?(request) request.params.has_key?(@fruit_type) end end

然后将类中的对象用作路由约束，如：

Then use objects from the class as routing constraints, as in:

map.connect "api/my/path", :contraints => FruitRecognizer.new(:apple), :controller => 'apples_controller', :action => 'my_action'
