我遇到使用Savon发布SOAP的 Ruby代码的问题

我有一个参数XML_BODY,显然没有被发送,或者,如果是,看起来为接收它的Java代码为null(如果我尝试返回“TEST”XML_BODY,响应显示“TEST null”)

其他数据似乎发送好 – 真的很困惑

客户端操作是pub_mugs(),post(),subscribe()

这个Python / Zeep代码完全成功

from requests import Session
from zeep import Client
from zeep.transports import Transport

if __name__ == "__main__":

  url="http://localhost:8080/Wormhole?wsdl"

  with open('../../web/web/xsd/DETEP2012-with-content.xml','r') as f:
    xml=f.read().replace('n','')

  session = Session()
  session.verify = False
  transport = Transport(session=session)
  client = Client(url,transport=transport)

  print client.service.PubMugs(username='usr',password='pwd') #SUCCESS

  print client.service.subscribe(username='usr',password='pwd') #SUCCESS

  print client.service.post(username='usr',password='pwd',mug='110',XML_BODY=xml) #SUCCESS

这个Ruby / Savon代码成功用于pub_mugs()和subscribe(),但是对于post()失败了

client = Savon.client(wsdl: ENV["WSDL"],:ssl_verify_mode => :none,:raise_errors => false,pretty_print_xml: true)

  doc = File.open("../web/web/xsd/DETEP2012-with-content.xml") { |f| Nokogiri::XML(f) }

  xml = doc.to_xml.delete("n").split(">",2)[1] # Removes initial <?xml ... >

  ap xml # The XML here looks correct

  response_pub_mugs = client.call(:pub_mugs,message: { username: "usr",password: "pwd" } )

  ap response_pub_mugs #SUCCESS

  response_subscribe = client.call(:subscribe,password: "pwd" } )      

  ap response_subscribe #SUCCESS

  #THIS CALL FAILS!
  response_post = client.call(:post,message: {
      username: "usr",password: "pwd",mug: "110",XML_BODY: xml
    }
  )

故障响应就是这个

:fault => {
     :faultcode => "S:Server",:faultstring => "java.lang.NullPointerException",:"@xmlns:ns4" => "http://www.w3.org/2003/05/soap-envelope"
}

堆栈跟踪并没有告诉我太多

post()操作运行一些访问MySQL数据库的Java代码

也许Savon正在生成一个不同的标题?我真的很茫然 – 任何帮助都非常感激

编辑 – 更多信息

post()的Java原型

@WebMethod(operationName = "post")
public String post(@WebParam(name = "username") String username,@WebParam(name = "password") String password,@WebParam(name = "mug") String mug,@WebParam(name = "XML_BODY") String XML_BODY)

BTW我也尝试将文件直接读入字符串xml,跳过Nokogiri文档

我已经尝试从字符串xml中删除所有空格,并删除了pretty_print

如果我更改了用户名或密码,我可以通过Java代码生成此响应,所以显然Java很高兴,直到这一点,它正在访问数据库好吧

:post_response => {
          :return => "Unknown username or password. Message NOT submitted.",:"@xmlns:ns2" => "http://seti/"
}

解决方法

回答是这样的

添加:无转换为rep_request_keys_to

client = Savon.client(wsdl: ENV["WSDL"],pretty_print_xml: false,convert_request_keys_to: :none)

用于散列键的文字字符串

response_post = client.call(:post,message: { 'username': 'usr','password': 'pwd','mug': '110','XML_BODY': xml })
