如何使用Python suds库创建soap头？

Question

我需要用这样的消息调用SOAP服务：

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:sub="https://secure.xpslogic.com/service/wijnen/sub">
   <soapenv:Header>
      <sub:auth>
         <token>?</token>
         <!--Optional:-->
         <user_id>?</user_id>
         <!--Optional:-->
         <user_token>?</user_token>
      </sub:auth>
   </soapenv:Header>
   <soapenv:Body>
      <sub:customer_logos_pull>
         <!--Optional:-->
         <language>?</language>
         <!--Optional:-->
         <limit>?</limit>
         <!--Optional:-->
         <options_utc>?</options_utc>
      </sub:customer_logos_pull>
   </soapenv:Body>
</soapenv:Envelope>

我有一些php示例代码，它将头设置如下（效果非常好）：

auth=array（）； $auth['token']='xxx'； 如果（$auth）{ //添加身份验证头 $this->；clients[$module]->；\uu setSoapHeaders( 新建SoapHeader( $命名空间， 'auth'， $认证 ) ); }在

我现在用Python suds lib构造（空）主体和头，如下所示：

^{pr2}$

但这给了我一条not well-formed (invalid token)消息。打开日志记录时，我发现以下消息：

DEBUG:suds.mx.core:processing:
(Content){
   tag = "auth"
   value =
      (auth){
         token = "xxx"
         user_id = None
         user_token = None
      }
   type = <Element:0x10ff8c950 name="auth">
   <Complex:0x10ff8cbd0>
      <Sequence:0x10ff8cc50>
         <Element:0x10ff8cd10 name="token" type="(u'string', u'http://www.w3.org/2001/XMLSchema')" />
         <Element:0x10ff8cd50 name="user_id" type="(u'string', u'http://www.w3.org/2001/XMLSchema')" />
         <Element:0x10ff8cd90 name="user_token" type="(u'string', u'http://www.w3.org/2001/XMLSchema')" />
      </Sequence>
   </Complex>
</Element>
 }

我觉得它很好，但是它也给出了一个not well-formed (invalid token)。看到关于如何传入soap头的suds docs has 3 examples，我也尝试了另外两个：

>>> token = client.factory.create('auth.token')
>>> token.set(TOKEN)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: token instance has no attribute 'set'

以及

>>> client.set_options(soapheaders={'auth': {'token': 'xxx'}})
>>> customerLogosPull = client.factory.create('customer_logos_pull')
>>> result = client.service.customer_logos_pull(customerLogosPull)

它在日志中给出了这个内容，并且仍然是一个not well-formed (invalid token)：

(Content){
   tag = "auth"
   value =
      {
         token = "xxx"
      }
   type = <Element:0x106049290 name="auth">
   <Complex:0x106049510>
      <Sequence:0x106049590>
         <Element:0x106049650 name="token" type="(u'string', u'http://www.w3.org/2001/XMLSchema')" />
         <Element:0x106049690 name="user_id" type="(u'string', u'http://www.w3.org/2001/XMLSchema')" />
         <Element:0x1060496d0 name="user_token" type="(u'string', u'http://www.w3.org/2001/XMLSchema')" />
      </Sequence>
   </Complex>
</Element>
 }

有人知道如何使用Python在头中正确地设置令牌吗？欢迎所有提示！在

Answer 1

我让我的肥皂头工作如下：

from suds.sax.element import Element
ssnp = Element("xsi:SessionHeader").append(Element('xsi:sessionId').setText("xxxxxxx"))
client.set_options(soapheaders=ssnp)

对应于下面在soap请求xml中显示的soap头

^{pr2}$

我们可以看到使用print client.last_sent()发送了什么请求

Answer 2

我试着

from suds.client import Client
WSDL_URL='http://apitest.comune.genova.it:28280/MANU_WSManutenzioni_MOGE/'

#Create the Client:
print("Print 1")
client = Client(url=WSDL_URL)

print("Print 2")
from suds.sax.element import Element
ssnp = Element("xsi:SessionHeader").append(Element('xsi:Authorization').setText("XXXXXXXXXXX"))
client.set_options(soapheaders=ssnp)

但是我在下面的行中遇到了一个错误

^{pr2}$

这里的错误是：

Traceback (most recent call last):

    return self.u2open(u2request)

During handling of the above exception, another exception occurred:
