如何使用 Python suds 庫創建肥皂頭？

Question

我需要使用如下消息調用 SOAP 服務：

<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 示例代碼，它設置標題如下（並且效果很好）：

身份驗證 = 數組（）； $auth['token'] = 'xxx'; if ($auth) { // 添加認證頭 $this->clients[$module]->__setSoapHeaders( new SoapHeader( $namespace, 'auth', $auth ) ); }

我現在使用Python suds lib構造（空）主體和標頭，如下所示：

from suds.client import Client
from suds import WebFault

client = Client(url='https://example.com/sub.wsdl')

auth = client.factory.create('auth')
auth.token = 'xxx'
client.set_options(soapheaders=auth)

customerLogosPull = client.factory.create('customer_logos_pull')
result = client.service.customer_logos_pull(customerLogosPull)

但這給了我一個not well-formed (invalid token)消息。 打開日志記錄時，我發現這是消息：

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>
 }

我看起來很不錯，但它也給出了一個not well-formed (invalid token) 。 看到suds 文檔有 3 個關於如何傳入肥皂頭的示例，我也嘗試了其他兩個：

>>> 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'

和

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

它在日志中提供了此內容，但仍然是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 在標頭中正確設置令牌嗎？ 歡迎所有提示！

Answer 1

我讓我的肥皂頭工作如下：

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

對應於soap請求xml中如下所示的soapHeaders

<SOAP-ENV:Header>
  <xsi:SessionHeader>
     <xsi:sessionId>xxxxxxx</xsi:sessionId>
  </xsi:SessionHeader>
</SOAP-ENV:Header>

我們可以看到使用print client.last_sent()發送了什么請求

Answer 2

我試試

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)

但我遇到了以下行的錯誤

client = Client(url=WSDL_URL) 

這里的錯誤：

Traceback (most recent call last):
  File "/usr/local/lib/python3.6/site-packages/suds/transport/http.py", line 67, in open
    return self.u2open(u2request)

    return url.open(u2request, timeout=tm)

During handling of the above exception, another exception occurred:
