如何用Python suds库创建肥皂标题？

问题描述

 < 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> 
<！ - 可选： - > 
< user_id>？< / user_id> 
<！ - 可选： - > 
< user_token>？< / user_token> 
< / sub：auth> 
< / soapenv：Header> 
< soapenv：Body> 
< sub：customer_logos_pull> 
<！ - 可选： - > 
< language>？< / language> 
<！ - 可选： - > 
< limit>？< / limit> 
<！ - 可选： - > 
< options_utc>？< / options_utc> 
< / sub：customer_logos_pull> 
< / soapenv：Body> 
< / soapenv：Envelope> 
  

我有一些php示例代码，它将头文件设置为如下所示）：

auth = array（）;
$ auth ['token'] ='xxx';
if（$ auth）{
// add auth header
$ this-> clients [$ module] - > __ setSoapHeaders（
new SoapHeader（
$ namespace，
'auth'，
$ auth
）
）;
}

我现在使用：来自suds.client的

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

但这给我一个不好形成（无效令牌）消息。打开日志记录时，我发现这是消息：

  DEBUG：suds.mx.core：processing：
 （内容）{
 tag =auth
值= 
（auth）{
令牌=xxx
 user_id =无
 user_token =无
} 
 type =<元素：0x10ff8c950 name =auth> 
< Complex：0x10ff8cbd0> 
<序列：0x10ff8cc50> 
< Element：0x10ff8cd10 name =tokentype =（u'string'，u'http：//www.w3.org/2001/XMLSchema'）/> 
< Element：0x10ff8cd50 name =user_idtype =（u'string'，u'http：//www.w3.org/2001/XMLSchema'）/> 
< Element：0x10ff8cd90 name =user_tokentype =（u'string'，u'http：//www.w3.org/2001/XMLSchema'）/> 
< / Sequence> 
< / Complex> 
< / Element> 
} 
  

我看起来很好，但它也给出了一个格式不正确（无效令牌）。看到关于如何传递肥皂标题，我尝试了其他两个：

 >>> token = client.factory.create（'auth.token'）
>>> token.set（TOKEN）
 Traceback（最近一次调用的最后一个）：
在< module>中，第1行的文件< stdin> 
 AttributeError：令牌实例没有属性'set'
  

和

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

它在日志中给出了这个内容， 格式不正确（无效标记）：

 （内容）{ 
 tag =auth
 value = 
 {
 token =xxx
} 
 type =<元素：0x106049290 name =auth > 
< Complex：0x106049510> 
<序列：0x106049590> 
< Element：0x106049650 name =tokentype =（u'string'，u'http：//www.w3.org/2001/XMLSchema'）/> 
< Element：0x106049690 name =user_idtype =（u'string'，u'http：//www.w3.org/2001/XMLSchema'）/> 
<元素：0x1060496d0 name =user_tokentype =（u'string'，u'http：//www.w3.org/2001/XMLSchema'）/> 
< / Sequence> 
< / Complex> 
< / Element> 
} 
  

有人知道如何使用Python在标头中正确设置标记吗？所有提示都欢迎！

解决方案

$ b $ （显示与soap头对应的client.set_options（soapheaders = ssnp）

下面的soap请求xml

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

我们可以使用 print client.last_sent（）

I need to call a SOAP service with a message like this:

<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>

I've got some php example code, which sets the headers as follows (and which works perfectly well):

auth = array();$auth['token'] = 'xxx';if ($auth) { // add auth header $this->clients[$module]->__setSoapHeaders( new SoapHeader( $namespace, 'auth', $auth ) );}

I now construct the (empty) body and the header as follows with the Python suds lib:

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)

but this gives me a not well-formed (invalid token) message. When turning on logging I find this to be the message:

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>
 }

It looks pretty fine by me, but it also gives a not well-formed (invalid token). seeing that the suds docs has 3 examples on how to pass in soap headers, I tried the other two as well:

>>> 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'

and

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

which gives this content in the logs, and still a 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>
 }

Does anybody know how I can correctly set the token in the header using Python? All tips are welcome!

解决方案

I got my soap Headers working as below:

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

corresponding to soap Headers shown below in soap request xml

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

We can see what request was sent using print client.last_sent()
