Question

我有以下从soapUI生成的WSDL。当我测试来自soapUI的请求，它工作正常，但从savon抛出异常。我在Linux上使用savon 0.9.2。

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/
envelope/" xmlns:mes="http://www.domain.com/sub/05/00/Messages">
   <soapenv:Header/>
   <soapenv:Body>
      <mes:loginRequest>
         <!--Optional:-->
         <mes:Username>admin</mes:Username>
         <!--Optional:-->
         <mes:Password>pass</mes:Password>
         <!--Optional:-->
         <mes:ImpersonationUsername></mes:ImpersonationUsername>
         <!--Optional:-->
         <mes:ApplicationName></mes:ApplicationName>
      </mes:loginRequest>
   </soapenv:Body>
</soapenv:Envelope>

导致错误的脚本：

require 'rubygems'
require 'savon'
require 'pp'

client = Savon::Client.new "http://domain/Service.asmx?WSDL"

response = client.request(:mes, "login") do
  soap.body = {
"mes:Username" => "test",
"mes:Password" => "test",
"mes:ImpersonationUsername"=>"Test",
"mes:ApplicationName"=>"test"
}
end
pp response.to_hash

输出：

     :fault_code=>"UnknownError"},
   :xmlns=>
    "http://www.domain.com/sub/05/00/Messages"}}

SoapUI的输出如下：

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

         <UserTicket>95bfaa81149f4c118c8724b837235cd5</UserTicket>
      </LoginResult>
   </soap:Body>
</soap:Envelope>

Answer 1

您可能希望在savon请求中设置命名空间：client.namespaces["xmlns:mes"] = "http://www.domain.com/sub/05/00/Messages"

Answer 2

您发送的请求会创建以下肥皂消息

  <?xml version="1.0" encoding="UTF-8"?>
    <env:Envelope xmlns:xsd="http://www.w3.org/2001/XMLSchema"
                  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                  xmlns:mes="urn:namespace.com"
                  xmlns:env="http://schemas.xmlsoap.org/soap/envelope/">
  <env:Body>
    <mes:login>
    <mes:Username>test</mes:Username>
    <mes:Password>test</mes:Password>
    <mes:ImpersonationUsername>Test</mes:ImpersonationUsername>
    <mes:ApplicationName>test</mes:ApplicationName>
    </mes:login>
  </env:Body>

我猜那不是你的意图吗？请在.new

之后在代码中插入以下行

Savon.configure do |c|
  c.log = true
end

显示传出消息。

简单的Savon SOAP请求无法正常工作
