在python中部署多个Web服务，即多个wsdl文件 [英] Deploy multiple web services, i.e. multiple wsdl files, in python

问题描述

我正在基于此示例，使用Spyne在python中创建Web服务. .但是，我所有的服务都组合到一个位于http://localhost:8000/?wsdl的wsdl文件中.我正在寻找另一种在单个wsdl文件中分别部署每个Web服务的方法，例如 http://localhost:8000/service1/?wsdl和http://localhost:8000/service2?wsdl

I'm creating web services in python using Spyne based on this example. However, all my services are combined into one wsdl file locating at http://localhost:8000/?wsdl. I'm looking for another way to deploy each web service separately in a single wsdl file, e.g. http://localhost:8000/service1/?wsdl and http://localhost:8000/service2?wsdl

推荐答案

Spyne为此提供了一个WsgiMounter类:

Spyne has a WsgiMounter class for this:

from spyne.util.wsgi_wrapper import WsgiMounter

app1 = Application([SomeService], tns=tns,
        in_protocol=Soap11(), out_protocol=Soap11())
app2 = Application([SomeOtherService], tns=tns,
        in_protocol=Soap11(), out_protocol=Soap11())
wsgi_app = WsgiMounter({
    'app1': app1,
    'app2': app2,
})

现在，您可以使用与传递WsgiApplication实例相同的方式，将wsgi_app传递给Wsgi实现.

Now you can pass wsgi_app to the Wsgi implementation that you're using the same way you'd pass a WsgiApplication instance.

您的Wsgi实现也肯定具有类似的功能，您也可以在例如您需要为根请求提供服务，而不是为空的404请求提供服务.

Your Wsgi implementation also would definitely have a similar functionality, you can also use that in case e.g. you need to serve something for the root request instead of an empty 404 request.

可以在以下位置找到最新的完全正常工作的示例:

请注意，您不能将一个Service类用于多个应用程序.如果必须这样做，可以这样:

Please note that you can't use one Service class with multiple applications. If you must do that, you can do it like this:

def SomeServiceFactory():
    class SomeService(ServiceBase):
        @rpc(Unicode, _returns=Unicode)
        def echo_string(ctx, string):
            return string
    return SomeService

，并对每个Application实例使用SomeServiceFactory()调用.

and use the SomeServiceFactory() call for every Application instance.

例如

app1 = Application([SomeServiceFactory()], tns=tns,
        in_protocol=Soap11(), out_protocol=Soap11())
app2 = Application([SomeServiceFactory()], tns=tns,
        in_protocol=Soap11(), out_protocol=Soap11())

希望有帮助.
