Question

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，则看到接收它的Java代码为空（如果我尝试返回＆＃34; TEST＆＃34; + XML_BODY，响应显示＆＃34; TEST null＆＃34;）

其他数据似乎发送好了 - 真的很困惑

客户端操作是pub_mugs（），post（），subscribe（）

此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（），但对于post（）

失败

  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, message: { username: "usr", 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多少

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

如果我更改用户名或密码，我可以通过Java代码生成此响应，因此显然Java在此之前很开心，而且正在访问数据库

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

Answer 1

回答是这个

已添加：无转换请求，以及convert_request_keys_to

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

SOAP post（）操作获取Java nullptr异常
