在python中使用zeep从wsdl文件中提取数据。

Question

我有访问wsdl文件，我需要得到响应的药物清单。

但我被它卡住了，在这里我的尝试。

from zeep import Client
from requests.auth import HTTPBasicAuth  
from requests import Session
from zeep.transports import Transport

username = 'username'
password = 'password'
wsdl = 'wsdl link'

session = Session()
session.auth = HTTPBasicAuth(username, password)
cl = Client(wsdl,transport=Transport(session=session))
r = cl.service.getDrugList('DRUGSTATUS')
print(r['DRUGSTATUS'])

它给我这个错误

zeep.exceptions.Fault: 80210

当我把参数从

r = cl.service.getDrugList()

它给我这个错误

raise exceptions.ValidationError(
zeep.exceptions.ValidationError: Missing element DRUGSTATUS (DrugListServiceRequest.DRUGSTATUS)

应@Tarique先生的请求

据此链接https:/github.commvantellingenpython-zeepissues297#issuecomment-271803117。我使用同样的命令，并给我同样的输出为mzssp wsdl linke，因为我发现一个问题与Auth和这里的结果。

Answer 1

感谢所要求的输出。

从定义。getDrugList(DRUGSTATUS: xsd:string) -> DRUGLIST: {DRUG: ns0:drug[]} 它看起来像方法 getDrugList 只接受1个类型为string &amp的参数；它返回一个列表，其中包括 drug 项目。

你传递了一个参数'DRUGSTATUS'，我不确定这个参数是否是服务可以接受的有效状态。

r = cl.service.getDrugList('DRUGSTATUS')

你应该像这样调用这个方法

r = cl.service.getDrugList(DRUGSTATUS='some_status')
# where some_status is valid DRUGSTATUS string. It could be found in service docs or examples.

# then check the response status & content:
print(r.status_code)
print(r.content)

further if response 是一个有效的回应，那么 DRUGLIST 可使用 for 循环。

希望能帮到你
