命名空间错误python zeep

Question

我正在尝试读取此Soap API http://telemetriaws1.ana.gov.br/ServiceANA.asmx?WSDL。当我试图调用DadosHidrometeorologicosGerais函数时，我得到了这个错误：

File "/home/1234/.local/share/virtualenvs/data_getter-1W9NAele/lib/python3.6/site-packages/zeep/xsd/schema.py", line 570, in _get_component
return items[qname]
KeyError: <lxml.etree.QName object at 0x7f2e93fa6d00>
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
zeep.exceptions.LookupError: No element 'DocumentElement' in namespace None. Available elements are: NewDataSet

所有其他功能运行正常。

下面是我的代码：

 from zeep import Client

 client = Client('http://telemetriaws1.ana.gov.br/ServiceANA.asmx?WSDL')
 client.service.DadosHidrometeorologicosGerais(codEstacao='86450500', dataInicio='05/05/2018', dataFim='05/05/2018')

Answer 1

我不确定，但xml文件似乎是从某个数据集生成的。"id“属性与元素的标识不匹配。

一种可能的解决方案是省略对XML的zeep解析，并返回raw data。使用模块xml.etree.ElementTree来解析它。

from zeep import Client, Settings
import xml.etree.ElementTree as ET

settings = Settings(force_https=False, raw_response=True)
WSDL = 'http://telemetriaws1.ana.gov.br/ServiceANA.asmx?WSDL'

client = Client(WSDL, settings=settings)

response = client.service.DadosHidrometeorologicosGerais(codEstacao='86450500',
                                                     dataInicio='05/05/2018',
                                                     dataFim='05/05/2018')

root = ET.fromstring(response.content)
