我试图在Ruby中构建Web服务客户端时出现这些错误

Question

我正尝试在Ruby中构建Web服务客户端。

当我尝试调用下面SOAP4R Ruby脚本生成的Web服务客户端代码：

wsdl2ruby.rb --wsdl *[web_service_url]* --type client 

我收到以下错误：

的时候，我尝试调用下面的代码动态生成Web服务客户端：

require 'soap/wsdlDriver' 

WSDL_URL = "http://*[web_service_url]*" 
factory = SOAP::WSDLDriverFactory.new(WSDL_URL) 
driver = factory.create_rpc_driver 

我收到以下错误：

当我尝试调用上面相同的代码，但与不同的URL（生产URL，而不是测试环境URL），我得到一个不同的错误：

C：/ Ruby192 /lib/ruby/gems/1.9.1/gems/httpclient-2.2.1/lib/httpclient/session.rb:748:in initialize': getaddrinfo: A non-recoverable error occurred during a database lookup.

为什么会出现这些错误，以及如何解决它们？我知道Web服务已经开始工作，因为我可以在C＃.Net中构建Web服务客户端。

soap4r在Ruby 1.9中有许多已知的问题。您应该考虑使用其中一个较新的SOAP工具包，例如savon或handsoap。
