ActionWebService例子及相关

1. rails 2.0以上版本下载actionwebservice插件。
2. 放到项目的vendor/plugins目录下
3. 配置config/environment.rb:
  a.在 Rails::Initializer.run do |config|...end之前加入：

class Rails::Configuration
       attr_accessor :action_web_service
      end

   b.在 Rails::Initializer.run do |config|...end之间加入：

config.frameworks += [ :action_web_service]
  config.action_web_service = Rails::OrderedOptions.new
config.load_paths += %W( #{RAILS_ROOT}/app/apis
                           #{RAILS_ROOT}/vendor/plugins/actionwebservice/lib)

     c.在 Rails::Initializer.run do |config|...end之后加入：

require 'action_web_service'

4.app下新建目录：apis
5.在app/apis下新建文件:person_api.rb:

class PersonApi < ActionWebService::API::Base
  inflect_names false
  api_method :add, :expects => [:string], :returns => [:int]
  api_method :remove, :expects => [:int], :returns => [:bool]
end

6.在controller里新建person_controller.rb:

class PersonController < ActionController::Base
  protect_from_forgery  .....# 如果application.rb里有就需要加上
  layout "invoke"
  web_service_api PersonApi
  web_service_scaffold :invoke

  def add

    return 1
  end

  def remove
    
  end

end

7. views下新建目录：person/invoke
8.将\vendor\plugins\actionwebservice\lib\action_web_service\templates\scaffolds下的methods.erb,parameters.erb, result.erb放到新建的目录下。
9.将layout.erb改名为invoke.erb放到views/layouts下。
10.vendor\plugins\actionwebservice\lib\action_web_service\scaffolding.rb的render_invocation_scaffold方法：

if self.active_layout.nil?
                render :file => scaffold_path("layout")
              else
                render :file => self.active_layout
              end

改为：

if self.active_layout.nil?
                render :file => scaffold_path("layout")
              else
                render :template => self.active_layout
              end

8. 重启服务，在浏览器中输入：http://localhost:3000/person/invoke,出现方法列表，ok!
