在 python 中使用 zeep 从 wsdl 文件中检索数据

Question

我可以访问 wsdl 文件，我需要得到一份药物清单

但我被它困住了，我在这里尝试

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'])

它给了我这个错误

zeep.exceptions.Fault: 80210

当我从

中删除参数时

r = cl.service.getDrugList()

它给了我这个错误

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

在@Tarique 先生请求之后

根据这个链接 https://github.com/mvantellingen/python-zeep/issues/297#issuecomment-271803117 我使用相同的命令并为 mzssp wsdl linke 提供相同的输出，因为我发现 auth 有问题，这里是结果

感谢您要求的输出。

根据定义：getDrugList(DRUGSTATUS: xsd:string) -> DRUGLIST: {DRUG: ns0:drug[]} 看起来方法 getDrugList 仅采用 1 个字符串类型的参数并返回 drug 项目列表。

您正在传递一个参数“DRUGSTATUS”，我不确定它是否是服务可接受的有效状态：

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

你应该这样调用方法：

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)

如果response 是有效响应，则可以使用for 循环打印DRUGLIST。

希望对你有帮助
