如何解析来自 ruby​​ 客户端的 SOAP 响应?

问题描述

我正在学习 Ruby，我编写了以下代码来了解如何使用 SOAP 服务:

I am learning Ruby and I have written the following code to find out how to consume SOAP services:

require 'soap/wsdlDriver'
wsdl="http://www.abundanttech.com/webservices/deadoralive/deadoralive.wsdl"
service=SOAP::WSDLDriverFactory.new(wsdl).create_rpc_driver
weather=service.getTodaysBirthdays('1/26/2010')

我得到的回复是:

#<SOAP::Mapping::Object:0x80ac3714

我很难弄清楚如何在一个漂亮的表格中解析和显示返回的信息，甚至只是如何遍历记录并访问每个元素(即全名、年龄等).我经历了整个getTodaysBirthdaysResult.methods - Object.new.methods"并继续努力尝试找出如何访问元素，但后来我到了数组，我迷路了.

I am having a great deal of difficulty figuring out how to parse and show the returned information in a nice table, or even just how to loop through the records and have access to each element (ie. FullName,Age,etc). I went through the whole "getTodaysBirthdaysResult.methods - Object.new.methods" and kept working down to try and work out how to access the elements, but then I get to the array and I got lost.

如有任何帮助，我们将不胜感激.

Any help that can be offered would be appreciated.

推荐答案

如果你无论如何都要解析 XML，你不妨跳过 SOAP4r 并使用 Handsoap.免责声明:我是 Handsoap 的作者之一.

If you're going to parse the XML anyway, you might as well skip SOAP4r and go with Handsoap. Disclaimer: I'm one of the authors of Handsoap.

示例实现:

# wsdl: http://www.abundanttech.com/webservices/deadoralive/deadoralive.wsdl
DEADORALIVE_SERVICE_ENDPOINT = {
  :uri => 'http://www.abundanttech.com/WebServices/DeadOrAlive/DeadOrAlive.asmx',
  :version => 1
}

class DeadoraliveService < Handsoap::Service
  endpoint DEADORALIVE_SERVICE_ENDPOINT
  def on_create_document(doc)
    # register namespaces for the request
    doc.alias 'tns', 'http://www.abundanttech.com/webservices/deadoralive'
  end

  def on_response_document(doc)
    # register namespaces for the response
    doc.add_namespace 'ns', 'http://www.abundanttech.com/webservices/deadoralive'
  end

  # public methods

  def get_todays_birthdays
    soap_action = 'http://www.abundanttech.com/webservices/deadoralive/getTodaysBirthdays'
    response = invoke('tns:getTodaysBirthdays', soap_action)
    (response/"//NewDataSet/Table").map do |table|
      {
        :full_name => (table/"FullName").to_s,
        :birth_date => Date.strptime((table/"BirthDate").to_s, "%m/%d/%Y"),
        :death_date => Date.strptime((table/"DeathDate").to_s, "%m/%d/%Y"),
        :age => (table/"Age").to_s.gsub(/^\(([\d]+)\)$/, '\1').to_i,
        :known_for => (table/"KnownFor").to_s,
        :alive? => (table/"DeadOrAlive").to_s == "Alive"
      }
    end
  end
end

用法:

DeadoraliveService.get_todays_birthdays
