savon - 使用 Savon 对 Polarion 网络服务进行身份验证

Question

我正在尝试关注讨论 here使用 Ruby 和 Savon。我能够检索 session ID，但是每当我执行来自需要身份验证(跟踪器)的客户端的请求时，我都会收到“授权失败”错误。

require 'Savon'

tracker_url = 'http://myserver/polarion/ws/services/TrackerWebService?wsdl'
session_url = 'http://myserver/polarion/ws/services/SessionWebService?wsdl'

# todo handle bad login credentials gracefully
session_client = Savon.client(wsdl: session_url)
response = session_client.call(:log_in, message: {user_name: 'lsimons', password: 'mypassword'})
session_id = response.header[:session_id]

puts "Session ID: #{session_id}"

tracker_client = Savon.client(wsdl: tracker_url, soap_header: {"session" => session_id},     headers: {"sessionID" => session_id})

puts "Requesting Workitem"
begin
    tracker_client.call(:get_work_item_by_id, message: {project_id: 'myProject', workitem_id: 'myWorkitem'})
rescue
    puts "Client call failed"
end

此代码为 tracker_client 创建以下 SOAP 请求:

<?xml version="1.0" encoding="UTF-8"?>
<env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ins0="http://ws.polarion.com/TrackerWebService-impl" xmlns:ins1="http://ws.polarion.com/types" xmlns:ins2="http://ws.polarion.com/TrackerWebService-types" xmlns:ins3="http://ws.polarion.com/ProjectWebService-types" xmlns:tns1="http://ws.polarion.com/TrackerWebService" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <env:Header>
        <session>2164640482421325916</session>
    </env:Header>
    <env:Body>
        <tns1:getWorkItemById>
            <ins0:projectId>myProject</ins0:projectId>
            <ins0:workitemId>myWorkitem</ins0:workitemId>
        </tns1:getWorkItemById>
    </env:Body>
</env:Envelope>

但是，在论坛讨论中，sessionID 元素出现在标题之前。我不认为这在标准 SOAP 中是可能的？有没有办法通过 Savon 实现这一目标，还是我误解了论坛讨论？

我在同一个线程之后遇到了同样的问题。这就是我让它工作的方式(通过复制 log_in 请求的响应头):

tracker_client = Savon.client(
  wsdl: tracker_url,
  soap_header: {
    "ns1:sessionID" => session_id,
    :attributes! => {
      "ns1:sessionID" => {
        "env:actor"           => "http://schemas.xmlsoap.org/soap/actor/next",
        "env:mustUnderstand"  => "0",
        "xmlns:ns1"           => "http://ws.polarion.com/session"
      }
    }
  }
)
