如何使用 Savon 进行包含命名空间的 SOAP 调用

Question

我正在尝试连接到 this SOAP API. Specifically, I am trying to login via this login call。

文档指出我应该提出以下请求：

POST /service/replicatorV4.asmx HTTP/1.1
Host: demo12231.srv106.webshopdemo.net
Content-Type: text/xml; charset=utf-8
Content-Length: length
SOAPAction: "http://tempuri.org/Login"

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
    <Login xmlns="http://tempuri.org/">
      <username>string</username>
      <password>string</password>
    </Login>
  </soap:Body>
</soap:Envelope>

当我在SoapUI 发出以下请求：

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:tem="http://tempuri.org/">
  <soapenv:Header/>
  <soapenv:Body>
    <tem:Login>
      <tem:username>Administrator</tem:username>
      <tem:password>passw0rd12</tem:password>
    </tem:Login>
  </soapenv:Body>
</soapenv:Envelope>

然后我得到了这个令人满意的回复：

<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">
  <soap:Body>
    <LoginResponse xmlns="http://tempuri.org/">
      <LoginResult>48594fe6-41fd-45f9-9f84-89ef8c247b85</LoginResult>
    </LoginResponse>
  </soap:Body>
</soap:Envelope>

但是，当我和 Savon 提出这样的请求时：

require 'savon'

client          = Savon.client( :wsdl => "http://demo12231.srv106.webshopdemo.net/service/replicatorV4.asmx?WSDL",
                                :open_timeout => 100,
                                :read_timeout => 100,
                                :ssl_verify_mode => :none,
                                :log_level => :debug,
                                :log => false,
                                :logger => Rails.logger,
                                :convert_request_keys_to => :camelcase)

response        = client.call(:login, :message => {:username => "Administrator", :password => "passw0rd12"})

然后我得到了这个不满意的回复：

     :soap_action=>"http://tempuri.org/Login"}>>

响应的正文部分是：

{:login_response=>{:login_result=>nil, :@xmlns=>"http://tempuri.org/"}}

这告诉我，也许服务确实收到了整体请求，但没有获得变量。响应看起来很像我在 SoapUI 中使用错误的 username 和 password:

发出此请求时的响应

<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">
  <soap:Body>
    <LoginResponse xmlns="http://tempuri.org/">
      <LoginResult xsi:nil="true"/>
    </LoginResponse>
  </soap:Body>
</soap:Envelope>

我注意到变量中需要命名空间 tem。这可能与我的问题有关吗？还是有别的解释？

创建一个没有 Rails 的纯 Ruby 脚本。

然后根据您使用 SoapUI 创建的内容检查输出。 Post 差异，有人会提供帮助。

当我运行这个脚本时：

require 'savon'

c = Savon.client(wsdl:
                "http://demo12231.srv106.webshopdemo.net/service/replicatorV4.asmx?WSDL",
                log_level: :debug,
                log: true,
                pretty_print_xml: true)
response = c.call(:login,
                  :message => {:username => "Administrator", :password => "passw0rd12"})

对我有用。它可能是你的 Rails 部分中的某些东西会干扰。我不这样做 Rails 因此我在那里帮不了什么忙（我更喜欢 Sinatra :-)）。
