Question

大家晚上好。我想提一下，关于wsdl，肥皂，泡沫，我对这件事情都很新！试着提供尽可能多的信息。 wsdl就是这个http://api3.pingar.com/PingarAPIService.asmx?WSDL

我花了好几个小时试图找到我正在使用的代码有什么问题，但最终却没有结果。我借用了这里找到的代码：https://gist.github.com/maheshcr/1829570，并填写了必要的字段（AppID，KeyID）。我的问题是，当我运行此代码时，我收到：服务器引发的错误：'服务器无法处理请求。 ---＆GT;对象引用未设置为对象的实例。'

当我在网上看到类似的问题时，我认为它必须是一个印刷错误。在仔细检查并比较wsdl和代码调用之后，我没有发现任何错误。

我真的没有想法，作为最后的手段，我在这里寻求帮助。以下是在我的命令行上打印的请求正文：

(PingarAPIRequest){
   AppID = "12345abc" #hypothetical appid
   AppKey = "abcd123456" #hypothetical appkey
   Language = "en"
   RapidDiscovery = 
      (RapidDiscovery){
         Query = None
         Documents = 
            (Documents){
               string[] = <empty>
            }
         DocumentsFormat = <empty>
         NumberOfResults = None
         SummaryLength = None
         MinKeyphraseness = None
      }
   EntityExtraction = 
      (EntityExtractionRequest){
         Documents = 
            (ArrayOfString){
               string[] = 
                  "Just a random input where we expect to find iron man 3 and the hobbit as the extracted entities.
",
            }
         DocumentsFormat = "Text"
         IncludeSingleSiblings = True
         TaxonomyNames = 
            (TaxonomyNames){
               string[] = <empty>
            }
         NumberOfKeywords = 10
         EntitiesToExtract = 
            (EntitiesToExtract){
               EntityTypes[] = <empty>
            }
         WikifyLinkDensity = 0.5
      }
   ContentAnalysis = 
      (ContentAnalysis){
         Documents = 
            (Documents){
               string[] = <empty>
            }
         DocumentsFormat = <empty>
         SummaryLength = None
         EntitiesToRedact = 
            (EntitiesToRedact){
               EntityTypes[] = <empty>
            }
         EntitiesToSanitize = 
            (EntitiesToSanitize){
               EntityTypes[] = <empty>
            }
      }
 }

任何帮助和/或建议都将受到高度赞赏！在此先感谢您的时间，我将确保发布任何更多信息尽快。我希望这篇文章能够帮助其他人。

编辑：我认为添加suds.logging信息会很有用。调试模式 - suds.client：

<SOAP-ENV:Envelope xmlns:ns0="http://api.pingar.com/" xmlns:SOAP-             ENC="http://schemas.xmlsoap.org/soap/encoding/"             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-    ENV="http://schemas.xmlsoap.org/soap/envelope/">

纠正上述行。删除请求soap-ENV中的空格，如SOAP-ENC和SOAP-ENV之间的空格，您将得到您的响应。我尝试使用soapui，我得到了回复。

我通过删除空格尝试了以下请求。

<SOAP-ENV:Envelope xmlns:ns0="http://api.pingar.com/" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
