python实现webservice的几种方法

以下是Python实现WebService的三种方法：
1.使用Python自带的模块suds库实现WebService。

from suds.client import Client
url = 'http://www.webxml.com.cn/WebServices/WeatherWebService.asmx?wsdl'
client = Client(url)
result = client.service.getWeatherbyCityName('北京')
print(result)

2.使用Python自带的模块zeep库实现WebService。

from zeep import Client
url = 'http://www.webxml.com.cn/WebServices/WeatherWebService.asmx?wsdl'
client = Client(url)
result = client.service.getWeatherbyCityName('北京')
print(result)

3.使用第三方库spyne实现WebService。

from spyne import Application, rpc, ServiceBase, Integer, Unicode
from spyne.protocol.soap import Soap11
from spyne.server.wsgi import WsgiApplication

class HelloWorldService(ServiceBase):
    @rpc(Unicode, Integer, _returns=Unicode)
    def say_hello(ctx, name, times):
        return 'Hello, %s' % name * times

application = Application([HelloWorldService], tns='spyne.examples.hello', in_protocol=Soap11(validator='lxml'), out_protocol=Soap11())
wsgi_application = WsgiApplication(application)

if __name__ == '__main__':
    import logging
    from wsgiref.simple_server import make_server
    logging.basicConfig(level=logging.DEBUG)
    logging.getLogger('spyne.protocol.xml').setLevel(logging.DEBUG)
    logging.info("listening to http://127.0.0.1:8000")
    logging.info("wsdl is at: http://localhost:8000/?wsdl")
    server = make_server('127.0.0.1', 8000, wsgi_application)
    server.serve_forever()
