I'm attempting to utilize the ruby gem Savon to connect to a web service provided by propertyware (http://propertyware.com/apidocs/Getting-Started). I've successfully connected to the service via SoapUI and executed an echoString request. When I try to do the same via Ruby I get a null user authentication error.

Here's what I've tried in Ruby...

require 'rubygems'
require 'savon'

client = Savon::Client.new do
  wsdl.document = 'http://propertyware.com/pw/services/PWServices?wsdl'
  wsse.credentials 'username', 'pwd'
end

response = client.request :web, :echo_string, :body => {:arg => "Hello world."}

Which produces the following xml...

<env:Envelope xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns:web="http://propertyware.com/pw/services/PWServices" 
    xmlns:env="http://schemas.xmlsoap.org/soap/envelope/" 
    xmlns:ins0="http://propertyware.com/pw/services/PWServices"

    xmlns:ins4="http://xml.apache.org/xml-soap">
    <env:Header>
        <wsse:Security xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd">
            <wsse:UsernameToken xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd" wsu:Id="UsernameToken-1">
                <wsse:Username>user</wsse:Username>
                <wsse:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText">pwd</wsse:Password>
            </wsse:UsernameToken>
        </wsse:Security>
    </env:Header>
    <env:Body>
        <web:echoString>
            <arg>Hello world.</arg>
        </web:echoString>
    </env:Body>
</env:Envelope>

Here's the xml produced by SoapUI...

<soapenv:Envelope xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" 
    xmlns:web="http://webservices" >
   <soapenv:Header>
      <wsse:Security xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd">
         <wsse:UsernameToken wsu:Id="UsernameToken-1" xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd">
            <wsse:Username>user</wsse:Username>
            <wsse:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText">pwd</wsse:Password>
            <wsse:Nonce EncodingType="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-soap-message-security-1.0#Base64Binary">R41mCRd+tY+xthhE/YISLQ==</wsse:Nonce>
            <wsu:Created>2011-10-25T09:52:40.220Z</wsu:Created>
         </wsse:UsernameToken>
      </wsse:Security>
   </soapenv:Header>
   <soapenv:Body>
      <web:echoString soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
         <arg xsi:type="xsd:string">?</arg>
      </web:echoString>
   </soapenv:Body>
</soapenv:Envelope>

One obvious difference is that SoapUI includes a nonce key and a createdAt timestamp. I'm not sure how to make savon do that without moving to digest auth. (and fwiw that doesn't work).

I'm not real savoy in the ways of web services - any guidance would be much appreciated.

Also - here's the response when I attempt to connect via savon:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <soapenv:Body>
        <soapenv:Fault>
            <faultcode xmlns:ns1="http://xml.apache.org/axis/">ns1:Server.Unauthenticated</faultcode>
            <faultstring>User 'null' not authenticated (unknown user)</faultstring>
            <detail>
                <ns2:hostname xmlns:ns2="http://xml.apache.org/axis/">rcpppwwwapt012.realpage.com</ns2:hostname>
            </detail>
        </soapenv:Fault>
    </soapenv:Body>
</soapenv:Envelope>

TIA! Bob

尝试将 wsse 中的摘要设置为 true。这将指示 Savon 将 nonce 和 createdAt 添加到请求中：

wsse.credentials 'username', 'pwd', :digest

在 Savon 版本 2 中，您需要以下内容：

client = Savon.client do
  wsdl 'https://webservice/theservice.wsdl'  
  wsse_auth("user", "pass", :digest)
end

我相信第一步是处理错误。

<faultstring>User 'null' not authenticated (unknown user)</faultstring>

您的凭据未传递给服务。
