使用 Ruby Savon 客户端连接到 PHP NuSOAP 服务器

Question

我正在尝试连接到使用 PHP NuSoap 库设置的远程 SOAP 服务。我正在使用 Ruby Savon 客户端进行连接。

访问服务的 WDSL 地址 (http://example.com/api/webservice.php?wdsl) 会提供有关我尝试使用的端点的以下信息：

   Name: addsubscription
   Binding: webserviceBinding
   Endpoint: http://www.example.com/api/webservice.php
   SoapAction: http://www.example.com/api/webservice.php/addsubscription
   Style: rpc
   Input:
     use: encoded
     namespace:
     encodingStyle: http://schemas.xmlsoap.org/soap/encoding/
     message: addsubscriptionRequest
     parts:
   Output:
     use: encoded
     namespace:
     encodingStyle: http://schemas.xmlsoap.org/soap/encoding/
     message: addsubscriptionResponse
     parts:
   Namespace:
   Transport: http://schemas.xmlsoap.org/soap/http
   Documentation:

像这样设置我的 Savon 客户端：

client = Savon::Client.new(wsdl: "http://www.example.com/api/webservice.php?wdsl")

然后尝试调用“添加订阅”方法：

response = client.call(:addsubscription) do
  message my_hash_of_stuff
end

在日志中给出以下错误 -

Savon::UnknownOperationError: Unable to find SOAP operation: :addsubscription
Operations provided by your service: []

像这样设置客户端：

client = Savon.client do
  endpoint "http://www.example.com/api/webservice.php"
  namespace ''
end

然后运行与上面相同的调用会引发 Savon::SOAPFault 错误，我假设这是由于缺少命名空间属性（我'不确定如何从这个错误中进一步调试/收集信息）？

根据以上信息，我应该如何配置 Savon 客户端以连接到该服务？

编辑：

像这样设置客户端 -

client = Savon.client(namespace: '', endpoint: 'http://www.example.com/api/webservice.php')

然后调用（使用填充的 message_hash 变量）

response = client.call(:addsubscription,
                     message: message_hash)

吐出以下错误：

看起来您使用的是过时的 Savon 版本

一个最小的实现可能如下所示：

require 'savon'

WSDL = 'http://www.example.com/api/webservice.php?wdsl'

client = Savon.client(wsdl: WSDL,
                      log: true,
                      log_level: :debug,
                      pretty_print_xml: true)
response = client.call(:addsubscription,
                        message: my_hash_of_stuff)
print response.to_hash
