更新05-09-2019 ：我仍然无法解决此问题，但我至少想出了问题的根源。显然Zeep无法确定某些元素的类型，我想这就是导致我最初描述的错误的原因：
DEBUG:zeep.xsd.schema:register_element('{http://eur-lex.europa.eu/search}WORK_PART_OF_WORK', <Element(name='WORK_PART_OF_WORK', type=<UnresolvedType(qname='{http://eur-lex.europa.eu/search}Relation')>)>)
这发生在多个元素上，所以我现在的问题是如何处理这些情况。有没有一种方法可以手动定义无法识别的元素的类型？
原始帖子：
我正在使用Python 3.6和Flask开发Web应用程序，在这里我需要使用SOAP API从Web服务获取一些数据。我已经安装了Zeep模块来执行此操作，但是由于这是我第一次使用SOAP API，因此Zeep非常迷路。 据我所知，请求已正确发送，并且正在终端窗口中从Web服务接收信息，但是随后出现以下错误：
AttributeError：'str'对象没有属性'keys'
以下是我需要使用的WSDL：https://eur-lex.europa.eu/eurlex-ws?wsdl和我要运行的XML查询，我已经在SOAPUI中对其进行了测试，并且效果很好：
<soap:Body>
<sear:searchRequest>
<sear:expertQuery>Title~"Decision (EU) 2016/342"</sear:expertQuery>
<sear:page>1</sear:page>
<sear:pageSize>10</sear:pageSize>
<sear:searchLanguage>en</sear:searchLanguage>
</sear:searchRequest>
</soap:Body>
我在Python中的代码是：
history = HistoryPlugin()
client = Client("https://eur-lex.europa.eu/eurlex-ws?wsdl", wsse=UsernameToken("#######","###########"), plugins=[history])
request_data = {
'expertQuery': 'Title~"Decision (EU) 2016/342"',
'page': 1,
'pageSize': 10,
'searchLanguage': 'en'
}
response = client.service.doQuery(**request_data)
在终端窗口中，我看到请求正在发送并且正在接收数据：

我完全迷路了，不知道如何解决此问题，因为我不了解该错误的含义，并且无法在Zeep中在线找到有关此特定错误的任何信息。
有什么想法吗？
