HTTP POST方式调用SOAP OPERATION类的接口

wsdl地址或者接口地址中有多个方法(operation)

如下是soapui测试的例子，wsdl地址下包含多个operation，但是现在我想用http的方式，只做getKnowledgePartsDatabase方法。

 

因为soap的调用是直接传的xml，所以需要做两个strans来把数据转换一下。这里接口用的是hashmap，所以在abap转换xml的只需要传一个内表，转换里循环处理一下就可以了。如下：蓝框内为全部soapui的xml数据，只是将key value换成了loop

 

到这里就可以做建单的转换测试了。

 转过的xml自带了sap的Envelope和header，所以程序里给处理调，没想其他方法，如果有，可以推荐下，谢谢！

 

然后是写返回的转换，类型的xml

 

然后输数据处理
