的Python /肥皂水：類型未找到：「XS：複雜類型」

Question

我有一個使用Suds調用SOAP的Web服務（該服務是寫在ASP.net）以下簡單的Python測試腳本：

from suds.client import Client 

url = 'http://someURL.asmx?WSDL' 

client = Client(url) 

result = client.service.GetPackageDetails("MyPackage" ) 

print result 

當我運行這個測試腳本，我收到以下錯誤（使用代碼標籤，因爲它不換行）：

No handlers could be found for logger "suds.bindings.unmarshaller" 
Traceback (most recent call last): 
    File "sudsTest.py", line 9, in <module> 
    result = client.service.GetPackageDetails("t3db" )

suds.TypeNotFound: Type not found: 'xs:complexType' 

在源WSDL文件的頭展望（重新格式化，以適合）：

<?xml version="1.0" encoding="utf-8" ?> 
<wsdl:definitions xmlns:http="http://schemas.xmlsoap.org/wsdl/http/" 
xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" 
xmlns:s="http://www.w3.org/2001/XMLSchema" 
xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" 
xmlns:tns="http://http://someInternalURL/webservices.asmx" 
xmlns:tm="http://microsoft.com/wsdl/mime/textMatching/" 
xmlns:mime="http://schemas.xmlsoap.org/wsdl/mime/" 
targetNamespace="http://someURL.asmx" 
xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"> 

我根據輸出的最後一行猜測：

suds.TypeNotFound: Type not found: 'xs:complexType' 

，我需要用Sud酒店的doctor class固定的模式，但作爲一個SOAP新手，我不知道需要什麼固定在我的情況。有沒有人有任何使用Suds修復/更正架構的經驗？

Ewall的資源是一個不錯的選擇。如果您嘗試在泡沫塑料卡票據中搜索，則可以看到其他人遇到問題similar to yours，但具有不同的對象類型。學習它的例子以及它們如何導入它們的命名空間是一種很好的方法。

The problem is that your wsdl contains a schema definition that references the (...) but fails to import the " http://schemas.xmlsoap.org/soap/encoding/ " namespace (and associated schema) properly. The schema can be patched at runtime using the schema ImportDoctor as discussed here: https://fedorahosted.org/suds/wiki/Documentation#FIXINGBROKENSCHEMAs .

This is a fairly common problem.

A commonly referenced schema (that is not imported) is the SOAP section 5 encoding schema. This can now be fixed as follows:

（所有重點都是我的）。

您可以嘗試這些文檔提供的行，添加WSDL中提供的名稱空間。這可能是一個嘗試錯誤的事情。

imp = Import('http://schemas.xmlsoap.org/soap/encoding/') 
# Below is your targetNamespace presented in WSDL. Remember 
# that you can add more namespaces by appending more imp.filter.add 
imp.filter.add('http://someURL.asmx') 
doctor = ImportDoctor(imp) 
client = Client(url, doctor=doctor) 

你沒有提供你正在使用的WSDL，我想你有理由不顯示給我們......所以我覺得你必須自己去嘗試這些可能性。祝你好運！
