Python的SUDS TypeNotFound複雜類型的名稱與Python的肥皂水「__」

我遇到另一個可怕的錯誤TypeNotFound（Python 2.7版，無泡沫jurko == 0.6）Python的SUDS TypeNotFound複雜類型的名稱與Python的肥皂水「__」

開始這些XSD的相關部分：

<xs:complexType final="extension restriction" name="requestHeader"> 
    <xs:sequence> 
     <xs:element minOccurs="0" name="type" type="tns:requestType"/> 
     <xs:element minOccurs="0" name="userID" type="xs:string"/> 
     <xs:element minOccurs="0" name="sessionID" type="xs:string"/> 
    </xs:sequence> 
</xs:complexType> 
<xs:complexType final="extension restriction" name="requestType"> 
    <xs:sequence> 
     <xs:element name="__value" type="xs:int"/> 
    </xs:sequence> 
</xs:complexType>

WSDL正確導入XSD，所以我不相信醫生會幫助：

<wsdl:definitions 
    name="FooBarService" 
    targetNamespace="foo.bar.ns" 
    xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" 
    xmlns:tns="foo.bar.ns" 
    xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
    xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/"> 
<schema xmlns="http://www.w3.org/2001/XMLSchema"> 
<import namespace="foo.bar.ns" schemaLocation="someschemafile.xsd"/> 
<import namespace="http://jaxb.dev.java.net/array" schemaLocation="someschemafile2.xsd"/>

而且someschemafile.xsd：

<xs:schema 
    xmlns:xs="http://www.w3.org/2001/XMLSchema" 
    xmlns:ns1="http://jaxb.dev.java.net/array" 
    xmlns:tns="foo.bar.ns" 
    attributeFormDefault="unqualified" 
    elementFormDefault="unqualified" 
    targetNamespace="foo.bar.ns">

然後，我創建requestHeader和requestType：

q = soap_client.factory.create('requestHeader') 
print q 

(requestHeader){ 
    type = 
    (requestType){ 
     __value = None 
    } 
    userID = None 
    sessionID = None 
}

然後：

q.type = soap_client.factory.create('requestType') 
q.type.__value = 42 
q.userID = "foo" 
q.sessionID = "bar" 
print q 

(requestHeader){ 
    type = 
     (requestType){ 
      __value = 42 
     } 
    userID = "foo" 
    sessionID = "bar" 
}

，然後我嘗試調用使用requestHeader方法，在這之後，我得到：

TypeNotFound(u"Type not found: '__value'",)

我也試過這個：

q = { 
    'type': 42, 
    'userID': "foo", 
    'sessionID': "bar" 
}

但這呈現錯誤的SOAP消息：

<header> 
    <type>42</type> 
    <userID>foo</userID> 
    <sessionID>bar</sessionID> 
</header>

，而不是

<header> 
    <type> 
     <__value>42</__value> 
    </type> 
    <userID>foo</userID> 
    <sessionID>bar</sessionID> 
</header>

這到底是由服務拒絕。

很抱歉，我無法提供完整的WSDL和XSD，它們受到限制。

我能做些什麼來使泡沫創建正確的SOAP XML與__value元素？

我使用的是WSDL的本地副本，所以我可以對其進行更改，只要它能夠生成正確的SOAP XML。不過，我不知道要改變什麼。

編輯：增加了幾分清洗回溯（刪除的東西被稱爲SUDS方法之前）request是肥皂水對象，其中的一個屬性的類型是requestHeader

「，然後我嘗試調用使用requestHeader方法，之後，我得到：「請顯示你打電話的方法。 – dopstar

你必須記住的是，以'__variable'這樣的雙下劃線開頭的類變量對於python中的類是私有的（它們實際上被破壞不是真正的私有），這可能是你遇到困難的原因。如果必須，我會說停止使用雙下劃線或使用一個下劃線。通過使用破損的名字的籃球是可能的，但它真的很混亂，不pythonic，我會直接勸阻它。 – dopstar

是的，我知道Python中有兩個下劃線，但是......我不是所請求的SOAP API的作者，我只是在使用它......而那個東西就是企業Java怪獸，其中雙下劃線名稱意味着什麼都沒有。。我會看看我是否可以做一些事情來防止Python中的名稱混亂，也許這就是爲什麼SUDS會感到困惑。 Thnx – Tomislav

按@dopstar評論的，這是因爲錯誤的在SUDS中。因爲我沒有時間試圖修復它的來源，我設計有點醜陋的解決方法

from lxml import etree 

etree_object = build_XML_using_etree() 

soap_client.service.someServiceMethod(
    __inject={'msg': etree.tostring(etree_object)} 
)

醜陋的部分，其實並不是在這裏看到它是針織，因爲我們可以隱藏在背後build_XML_using_etree方法的XML的邏輯不要依賴SUDS在這裏做。

在另一方面，一旦原始XML注入SUDS棧，一切工作得很好，所以也許這不是那麼糟糕......
