如何在soap動作請求中添加可選參數？

Question

我想在soap_action添加可選paramteter（wash_out）的要求，這裏是代碼

soap_action "DeActivate_VAS_Request", 
:args => {:some_arguments}, :return => {:return_values} 

和操作

<operation name="DeActivate_VAS_Request"> 
    <soap:operation soapAction="DeActivate_VAS_Request"/> 
    <input> 
     <soap:body 
      use="encoded" 
      encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" 
      namespace="urn:WashOut"/> 
    </input> 
    <output> 
    <soap:body use="encoded" 
       encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" 
       namespace="urn:WashOut"/> 
    </output> 
</operation> 

行動應該是可選的，請幫助。

你可以猴子patch_out 0.5.2。把這個config/initializers/washout_monkey_patch.rb

WashOut::Param.class_eval do 
    attr_accessor :optional 

    def initialize(name, type, multiplied = false, optional = false) 
     type ||= {} 

     @name  = name.to_s 
     @raw_name = name.to_s 
     @map  = {} 
     @multiplied = multiplied 
     @optional = optional 

     if WashOut::Engine.camelize_wsdl.to_s == 'lower' 
     @name = @name.camelize(:lower) 
     elsif WashOut::Engine.camelize_wsdl 
     @name = @name.camelize 
     end 

     if type.is_a?(Symbol) 
     @type = type.to_s 
     elsif type.is_a?(Class) 
     @type   = 'struct' 
     @map   = self.class.parse_def(type.wash_out_param_map) 
     @source_class = type 
     else 
     @type = 'struct' 
     @map = self.class.parse_def(type) 
     end 
    end 

    def flat_copy 
     copy = self.class.new(@name, @type.to_sym, @multiplied, @optional) 
     copy.raw_name = raw_name 
     copy 
    end 
end 

WashOutHelper.module_eval do 
    def wsdl_occurence(param, inject, extend_with = {}) 
    if param.multiplied 
     data = { 
     "#{'xsi:' if inject}minOccurs" => 0, 
     "#{'xsi:' if inject}maxOccurs" => 'unbounded' 
     } 
    elsif param.optional 
     data = { 
     "#{'xsi:' if inject}minOccurs" => 0, 
     } 
    else 
     data = {} 
    end 

    extend_with.merge(data) 
    end 

    def wsdl_data(xml, params) 
    Rails.logger.debug params 
    params.each do |param| 
     tag_name = param.name 

     if !param.struct? 
     if param.multiplied 
      param.value = [] unless param.value.is_a?(Array) 
      param.value.each do |v| 
      xml.tag! tag_name, v, "xsi:type" => param.namespaced_type 
      end 
     elsif param.optional 
      if !param.value.nil? 
      xml.tag! tag_name, param.value, "xsi:type" => param.namespaced_type 
      end 
     else 
      xml.tag! tag_name, param.value, "xsi:type" => param.namespaced_type 
     end 
     else 
     if param.multiplied 
      param.map.each do |p| 
      xml.tag! tag_name, "xsi:type" => param.namespaced_type do 
       wsdl_data(xml, p.map) 
      end 
      end 
     elsif param.optional 
      if !param.map.empty? 
       xml.tag! tag_name, "xsi:type" => param.namespaced_type do 
       wsdl_data(xml, param.map) 
       end 
      end 
     else 
      xml.tag! tag_name, "xsi:type" => param.namespaced_type do 
      wsdl_data(xml, param.map) 
      end 
     end 
     end 
    end 
    end 
end 

要定義一個可選參數，使用沖洗::帕拉姆構造函數，傳遞一個第三個參數等於false和第四個參數等於true。在以下示例中，第三個輸入參數和第二個輸出參數將被定義爲可選項：

soap_action "YourWebService", 
    :args => { 
     :arg1 => :string, 
     :arg2 => :string, 
     :arg3 => WashOut::Param.new(:arg3, :string, false, true), 
    }, 
    :return => { 
     :arg1 => :string, 
     :arg2 => WashOut::Param.new(:arg2, :string, false, true), 
    }, 
    :to  => :web_service
