SOAP ()操作获得Java nullptr异常
SOAP ()操作获得Java nullptr异常
提问于 2017-03-10 07:32:30
我对Ruby代码使用Savon发布SOAP有个问题
我有一个参数XML_BODY，它显然没有被发送，或者，如果它是空的，在接收它的代码看来是空的(如果我试图返回"TEST"+XML_BODY，响应显示"TEST null")
其他数据似乎发送得很好--真的很困惑
客户端操作是pub_mugs()、post()、subscribe()
这个Python/Zeep代码完全成功了
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代码成功地用于pub_mugs()和订阅()，但是对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

也许Savon会产生不同的标题？我真的很不知所措-任何帮助都很感激
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)顺便说一下，我还尝试将文件直接读入字符串xml，跳过Nokogiri文档。
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，我就可以得到由Java代码生成的响应，因此很明显，Java在此之前是很高兴的，而且它正在访问数据库。

答案是这样
添加:无用于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 })页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
