如何用Python suds库创建肥皂标题？ [英] How to create soap header with Python suds library?
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 Python suds lib ：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）。看到起草文档有3个示例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！
$ b $ （
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!
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()
