wash_out gem 访问 soap_config 方法时出错

Question

我无法从使用 wash_out gem 创建的 SOAP 服务获得 xml 响应。现在我只想要一个将整数转换为字符串的 soap 响应，就像在 washout 示例代码中所做的那样。知道我在这里做错了什么吗？

我的控制器代码是：

soap_service namespace: 'http://localhost:3000/api/accounts/wsdl'
soap_action "get_new_account",
          :args   => :integer,
          :return => :string
def get_new_account
render :soap => params[:value].to_s
end

服务器响应以下 rpc wsdl：

<definitions xmlns="http://schemas.xmlsoap.org/wsdl/" xmlns:tns="http://localhost:3000/api/accounts/wsdl" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:soap-enc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" name="api_accounts" targetNamespace="http://localhost:3000/api/accounts/wsdl">
<types>
<schema xmlns="http://www.w3.org/2001/XMLSchema" targetNamespace="http://localhost:3000/api/accounts/wsdl"></schema>
</types>
<portType name="api_accounts_port">
<operation name="get_new_account">
<input message="tns:get_new_account"/>
<output message="tns:get_new_account_response"/>
</operation>
</portType>
<binding name="api_accounts_binding" type="tns:api_accounts_port">
<soap:binding style="rpc" transport="http://schemas.xmlsoap.org/soap/http"/>
<operation name="get_new_account">
<soap:operation soapAction="get_new_account"/>
<input>
<soap:body use="encoded" encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" namespace="http://localhost:3000/api/accounts/wsdl"/>
</input>
<output>
<soap:body use="encoded" encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" namespace="http://localhost:3000/api/accounts/wsdl"/>
</output>
</operation>
</binding>
<service name="service">
<port name="api_accounts_port" binding="tns:api_accounts_binding">
<soap:address location="http://localhost:3000/api/accounts/action"/>
</port>
</service>
<message name="get_new_account">
<part name="value" type="xsd:int"/>
</message>
<message name="get_new_account_response">
<part name="value" type="xsd:string"/>
</message>
</definitions>

soap 客户端正在发送以下消息：

<Envelope xmlns="http://schemas.xmlsoap.org/soap/envelope/">
    <Body>
        <get_new_account xmlns="http://localhost:3000/api/accounts/wsdl">
            <value>123</value>
        </get_new_account>
    </Body>
</Envelope>

服务器因以下内部错误而失败：

Started POST "/api/accounts/action" for ::1 at 2016-04-22 11:29:10 -0400

NoMethodError (undefined method `soap_config' for AccountsController:Class):

为了详细说明我的 rails 环境，我还包括了我的 Gemfile：

Answer 1

这意味着wash_out发现控制器有误。

gem源码(wash_out-0.9.2/lib/wash_out/router.rb):

class Router
  def initialize(controller_name)    # controller_name = "accounts"
    # @controller_name = AccountController
    # the controller maybe incorrect.
    @controller_name = "#{controller_name.to_s}_controller".camelize
  end
  ...
end

确保 gem 找到的控制器是正确的。

您的控制器代码是：

class Api::AccountsController < ApplicationController
  soap_service namespace: 'http://localhost:3000/api/accounts/wsdl'
  soap_action "get_new_account",
      :args   => :integer,
      :return => :string
  def get_new_account
    render :soap => params[:value].to_s
  end
end

正确的cofing/routes.rb代码为：

wash_out "Api::Accounts"

以上代码适用于 0.9.2 版本。

版本0.10.0，你可以这样做：

wash_out :accounts, module: "Api"
