如何使用Python Suds(版本0.3.6)导入XSD架构SOAP库:TypeNotFound异常?

标签: python soap wsdl suds

我正在尝试使用带有Python Suds的SABRE旅行网络服务,但是一个XSD似乎没有格式良好(可能在此架构中缺少命名空间)。


from suds.client import Client
wsdl = 'http://webservices.sabre.com/wsdl/sabreXML1.0.00/tpf/OTA_AirPriceLLSRQ.wsdl'
client = Client(wsdl, cache=None)

调试跟踪返回:

Ran 2 tests in 11.669s

Type not found: '(OTA_AirPriceRQ, http://webservices.sabre.com/sabreXML/2003/07, )'

这是逻辑:Python Suds在“无”命名空间中加载OTA_AirPriceRQ。 我读了“修复破坏的模式”Python Suds文档(https://fedorahosted.org/suds/wiki/Documentation#FIXINGBROKENSCHEMAs):


from suds.client import Client
from suds.xsd.doctor import ImportDoctor, Import
wsdl = 'http://webservices.sabre.com/wsdl/sabreXML1.0.00/tpf/OTA_AirPriceLLSRQ.wsdl'
imp = Import('http://webservices.sabre.com/sabreXML/2003/07/OTA_AirPriceLLSRQ', 'http://webservices.sabre.com/wsdl/sabreXML1.0.00/tpf/OTA_AirPriceLLSRQ.xsd')
d = ImportDoctor(imp)
client = Client(wsdl, cache=None, doctor=d)

但脚本返回另一个例外:

我不明白如何使用“医生”功能。有人可以帮帮我吗? 谢谢。

我刚刚向该Suds门票发布了一个解决方法。您可能需要查看它:https://fedorahosted.org/suds/ticket/239#comment:19

简而言之,这是解决方法代码:

from suds.client import Client
import sys
sys.setrecursionlimit(10000)
c = Client('http://url.to/endpoint?wsdl', cache=None)

这看起来像https://fedorahosted.org/suds/ticket/239。我把你的例子添加到了票证中。
