使用Ruby Savon客户端连接到PHP NuSOAP服务器

Question

我试图连接到已经使用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。

访问该服务的WDSL地址（http://example.com/api/webservice.php?wdsl）给出了关于终点，我尝试使用以下信息：

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: 

设置我的萨翁客户像这样：

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

和然后尝试调用“添加订阅”方法：

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

gi VES在日志下面的错误 -

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

设置客户端，像这样：

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

，然后运行相同的呼叫如上提出了萨翁::的SOAPFault错误，这我假设是由于缺乏名称空间属性（我不知道如何进一步调试/收集此错误中的信息）？

根据以上信息，我应该如何配置Savon客户端连接到此服务？

编辑：

设置客户机像这样 -

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

，然后调用（用填充message_hash VAR）

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

吐出以下错误：

它看起来像你在过时的萨翁版本< 2.x.我建议升级到版本2.x（2.11.1，因为我正在写）。随着v2的推出，界面发生了很大变化。

最小实现看起来是这样的：

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
