Web Service 之 Python -- spyne
概要
本文主要關注利用spyne實現web service, 介面引數為自定義資料型別和陣列
pip install spyne, suds, zeep
>>> import spyne, suds, zeep
>>> spyne.__version__'2.12.14'
>>> suds.__version__, zeep.__version__('1.3.3.0', '1.4.1')

Server部分
#!/usr/bin/python # coding:utf-8 from spyne import Application, rpc, ServiceBase from spyne import Integer, Unicode, Array, ComplexModel, Iterable, String from spyne.protocol.soap import Soap11 from spyne.server.wsgi import WsgiApplication from wsgiref.simple_server import make_server class Person(ComplexModel): name = Unicode age = Integer class HelloWorldService(ServiceBase): @rpc(Unicode, Integer, _returns=Iterable(Unicode)) def say_hello(self, name, times): for i in range(times): yield "Hello %s, It's the %s time to meet you." % (name, i + 1) @rpc(Array(Person), _returns=Iterable(Unicode)) def say_hello_1(self, persons): print('-------say_hello_1()--------') if not persons: yield 'None' for person in persons: print('name is : %s, age is %s.' % (person.name, person.age)) yield 'name is : %s, age is %s.' % (person.name, person.age) class HelloWorldService2(ServiceBase): @rpc(Array(String), _returns=Iterable(Unicode)) def say_hello_2(self, persons): if not persons: yield 'None' for person in persons: yield person application = Application([HelloWorldService, HelloWorldService2], 'spyne.examples.hello', in_protocol=Soap11(validator='lxml'), out_protocol=Soap11()) wsgi_application = WsgiApplication(application) if __name__ == '__main__': import logging host = '127.0.0.1' port = 8000 logging.info("listening to http://127.0.0.1:8000") logging.info("wsdl is at: http://localhost:8000/?wsdl") server = make_server(host, port, wsgi_application) server.serve_forever()
Client部分(Suds)
#!/usr/bin/python # coding:utf-8 from suds.client import Client host = '127.0.0.1' port = 8000 client = Client('http://%s:%s/?wsdl' % (host, port)) # print client persons = client.service.say_hello('zhangsan', 2) print persons print '-' * 20 person = {} person['name'] = 'zhangsan' person['age'] = 23 persons = client.factory.create('PersonArray') persons.Person.append(person) persons.Person.append(person) person = client.service.say_hello_1(persons) print person print '=' * 20 persons = client.factory.create('stringArray') persons.string.append('lisi') persons.string.append('zhangsan') person = client.service.say_hello_2(persons) print person
zeep - Python client
#!/usr/bin/python # coding:utf-8 from zeep import Client ip = '127.0.0.1' port = 8000 client = Client("http://%s:%s/?wsdl" % (ip, port)) # print(client.wsdl.dump()) ### say_hello factory = client.type_factory("ns0") r = client.service.say_hello('zhansgan', 3) print(r) ### say_hello_1 factory = client.type_factory("ns0") person = factory.Person(name='zhangsan', age=23) persons = factory.PersonArray([person, person]) r = client.service.say_hello_1(persons) print(r) ### say_hello_2 factory = client.type_factory("ns0") persons = factory.stringArray(["zhansgan", "lisi"]) r = client.service.say_hello_2(persons) print(r)
