ruby - SOAP post() 操作获取 Java nullptr 异常

Question

我在使用 Savon 发布 SOAP 的 Ruby 代码时遇到问题

我有一个参数 XML_BODY，它显然没有被发送，或者，如果是，对于接收它的 Java 代码来说看起来是 null(如果我尝试返回“TEST”+XML_BODY，响应显示“TEST null”)

其他数据似乎发送正常 - 真的很困惑

客户端操作有pub_mugs()、post()、subscribe()

这段 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

此 Ruby/Savon 代码对 pub_mugs() 和 subscribe() 成功，但对 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
    }
  )

故障响应是这样的

: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信息

post() 操作运行一些访问 MySQL 数据库的 Java 代码

也许 Savon 正在生成不同的 header ？我真的很茫然 - 非常感谢任何帮助

编辑 - 更多信息

post() 的 Java 原型(prototype)

@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)

顺便说一句，我还尝试将文件直接读入字符串 xml，跳过 Nokogiri 文档

而且我尝试从字符串 xml 中删除所有空格，并删除 pretty_print

如果我更改用户名或密码，我可以获得由 Java 代码生成的响应，所以显然 Java 在此之前很满意，并且可以正常访问数据库

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

Answer 1

答案是这样的

为 convert_request_keys_to 添加了 :none

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

哈希键使用文字字符串

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