如何使用 wsdl 文件创建异步 zeep 客户端？

Question

我有使用 zeep 创建肥皂客户端的代码。我的服务器不返回 wsdl 文件，但我在本地有它。

同步版本的工作原理如下：

import uuid
from os import path
import structlog
import zeep

logger = structlog.get_logger(__name__)



class SyncClient(object):
    def __init__(self, ip_address: str):
        self.ip_address = ip_address
        self.port = 8080
        self.soap_client = None
        self.corrupt_timeseries_files = []
        self.id = uuid.uuid4()

    def connect_soap_client(self):
        this_files_dir = path.dirname(path.realpath(__file__))
        wsdl = 'file://{}'.format(path.join(this_files_dir, 'SOAPInterface.wsdl'))

        transport = zeep.Transport(timeout=5, operation_timeout=3)

        client = zeep.Client(wsdl, transport=transport)
        location = "http://{}:{}".format(self.ip_address, str(self.port))

        self.soap_client = client.create_service("{urn:webservices}SOAPInterface", location)

然后 asyc 客户端看起来像这样：

class AsyncClient(object):
    def __init__(self, ip_address: str):
        self.ip_address = ip_address
        self.port = 8080
        self.soap_client: zeep.client.Client = None
        self.corrupt_timeseries_files = []
        self.id = uuid.uuid4()

    def connect_soap_client(self):
        this_files_dir = path.dirname(path.realpath(__file__))
        wsdl = 'file://{}'.format(path.join(this_files_dir, 'SOAPInterface.wsdl'))

        transport = zeep.transports.AsyncTransport(timeout=5, wsdl_client=wsdl, operation_timeout=3)

        client = zeep.AsyncClient(wsdl, transport=transport)
        location = "http://{}:{}".format(self.ip_address, str(self.port))

        self.soap_client = client.create_service("{urn:webservices}SOAPInterface", location)

我看到zeep的文档指出文件加载是同步的。但我不明白当我有本地文件时如何创建异步客户端......

当我在测试中运行代码时出现错误消息：

httpx.UnsupportedProtocol：不支持的 URL 协议“文件”

通过 zeep 和 httpx 源代码调试后，我发现解决方案实际上非常简单：

不指定file://{path}，只指定{path}。然后 WSDL 加载正常。
