Web Service系列之实例之spyne

原文链接: Web Service系列之实例之spyne

概要

本文主要关注利用spyne实现web service, 接口参数为自定义数据类型和数组

开发环境

➜  ~ cat /etc/redhat-release Fedora release 25 (Twenty Five)

➜  ~ python3Python 3.5.2 (default, Sep 14 2016, 11:28:32) >>> import spyne, suds, zeep>>> spyne.__version__'2.12.14'>>> suds.__version__, zeep.__version__('1.3.3.0', '1.4.1')

spyne ( https://github.com/arskom/spyne )

spyne webservice endpoint

接口说明
* say_hello_plus, 参数为Array(Name), 其中Name为自定义类型
* say_hello_plus2, 参数为Array(String)

suds - Python client

from suds.client import Clientip = '127.0.0.1'port = 8000client = Client("http://%s:%s/?wsdl" % (ip, port))#print(client)### say_hello_plusname = {}name["first_name"] = "Kylin"name["last_name"] = "Shu"names = client.factory.create("NameArray")names.Name.append(name)names.Name.append(name)r = client.service.say_hello_plus(names)print(r)### say_hello_plus2names = client.factory.create("stringArray")name = "Kylin"names.string.append(name)names.string.append(name)#r = client.service.say_hello('AAA', 2)#print(r)r = client.service.say_hello_plus2(names)print(r)

运行结果

➜  test_ws python3 ./client_spyne_suds.py(stringArray){   string[] =       "KylinShu",      "KylinShu", }(stringArray){   string[] =       "Kylin",      "Kylin", }

zeep - Python client

from zeep import Clientip = '127.0.0.1'port = 8000client = Client("http://%s:%s/?wsdl" % (ip, port))#print(client.wsdl.dump())### say_hello_plusfactory = client.type_factory("ns0")name = factory.Name(first_name='Kylin', last_name='Shu')names = factory.NameArray([name, name])r = client.service.say_hello_plus(names)print(r)### say_hello_plusfactory = client.type_factory("ns0")names = factory.stringArray(["Kylin", "Shu"])r = client.service.say_hello_plus2(names)print(r)
